Purging Croton

Croton tiglium

Euphorbiaceae

San: Jepalah, Dantibijah

Hin: Jamalgota

Ben: Jaypal Mal: Nirvalam

Tam: Nervalam, Sevalamkottai

Tel: Nepala

Importance: Purging croton or croton oil plant, a small evergreen tree with separate male and female flowers, is one among the seven poisons described in Ayurveda. The drug is well known for its drastic purgative property. The drug is found to be useful in ascites, anasarca, cold, cough, asthma, constipation, calculus, dropsy, fever and enlargement of the abdominal viscera. The seed paste is a good application for skin diseases, painful swellings and alopacia. The seed-oil is useful in chronic bronchitis, laryngeal affections, arthritis and lock jaw. Misraka-sneham is an important preparation using the drug (Nadkarni, 1954; Dey, 1980; Sharma, 1983).

Distribution: It is distributed throughout North India. It is cultivated in Assam, West Bengal and South India.

Botany: Croton tiglium Linn. belongs to the family Euphorbiaceae. It is a small evergreen tree, 4.5-6.0m in height with ash coloured smooth bark and young shoots sprinkled with stellate hairs. Leaves are oblong to ovate-lanceolate, obtuse or rounded at the 2-glanded box, acuminate, membraneous, yellowish green and minutely toothed. Flowers are small, unisexual, males on slender pedicels, females larger and on short thick pedicels. Fruits are ovoid or oblong trigonous capsules. Seeds are smooth, testa black and enclosing reddish brown oily endosperm (Warrier et al,1994). Other species belonging to the genus Croton are as follows:

C. aromaticus Linn. C. caudatus Geisel C. jouera Roxb.

C. malabaricus Bedd.

C. oblongifolius Roxb.

C. polyandrus Roxb. syn. Baliospermum montanum Muell-Arg.

C. reticulatus(Chopra et al, 1980)

Agrotechnology: The plant is propagated by seeds. Seeds are to be sown on seedbeds and about 2 months old seedlings are used for transplanting. Pits of size 50cm cube are to be taken at 3m spacing and filled with dried cowdung, sand and topsoil and formed into a mound. The seedlings are to be planted on these mounds. Irrigation during summer months is beneficial. Application of organic manure after every 6 months is desirable. Weeding is to be carried out one month after transplanting. The plant is not attacked by any serious pests or diseases. Fruits are formed at the end of first year. Fruits when ripen and start to crack are to be collected, dried in sun, then the outer shell is removed and again dried for one day before marketing (Prasad et al,1997).

Properties and activity: Oil contains phorbol myristate acetate (Husain et al, 1992). Seeds contain upto 20% protein and 30-50% lipids. Iso-guanine-D-ribose (crotoniside) and saccharose were isolated from the seeds. In fractionation of croton oil, liquid-liquid distribution procedures proved to be the separation tools of choice. The per hydrogenated parent hydrocarbon of phorbol is a perhydrocyclopropabenzulene called tigliane and phorbol is 1, 1a , 1b , 4, 4a, 7a , 7b, 8, 9, 9a-decahydro-4a , 7 , 9 , 9a - tetrahydroxy-3-(hydroxymethyl)-1, 1, 6, 8 tetramethyl-5-H-cyclopropa[3,4] benz [1.2-e]azulen-5- one. Phorbol, a tetracylic diterpene with a 5, 7, 6 and 3- membered ring has 6 oxygen functions. Phorbol accounts for 3.4% and 4- deoxy- 4 - phorbol for 0.29% of the weight of croton oil. Twenty- five phorbol-12, 13-diesters have been detected (Hecker et al, 1974). A toxin croton 1, mol. wt 72,000 has been isolated from the seeds (Lin et al, 1978).

Phorbol myristate acetate activates nitroblue tetrazolium reduction in human polymorphs. Seed and oil is purgative, rubefacient and anti-dote for snakebite. The seeds and oil are acrid, bitter, thermogenic, emollient, drastic purgative, digestive, carminative, anthelmintic, antiinflammatory, vermifuge, deterent, diaphoretic, expectorant, vesicant, irritant and rubefacient.... purging croton

Cholesterol

Cholesterol is a porridge-like substance found in animal fats: cream, whole milk, cheese, butter, meat, eggs, bacon, etc. There are two kinds of cholesterol in human blood serum, one of which is beneficial; the other, harmful if in excess. The beneficial, known as high density lipoprotein (HDL) is believed to keep down concentration of the harmful variety – low density lipoprotein (LDL). The desirable blood cholesterol level should be less than 5.2 mmol per litre. (Government: “Health of the Nation”)

Cholesterol is necessary for maintenance of brain and glandular system, the production of bile salts and certain hormones.

Excesses plug arteries with a gluey consistency. Fats may start furring up arteries from childhood, yet it may take many years for symptoms to develop. The more meat and dairy products eaten the more cholesterol is produced. 90 per cent cases of gall stones are composed of cholesterol. A link between coronary heart disease and high cholesterol levels is strong and consistent. Anger and hostility raise cholesterol level.

The first indication of narrowing of the arteries may be an attack of angina, severe chest pain occurring on exertion due to an inadequate supply of blood and oxygen to the heart muscle. No one should exceed a fat and cholesterol count of 40 per day. For those of moderate risk level, a count of below 30 is advised.

Dr Paul Durrington, consultant physician, Manchester Royal Infirmary and researcher in lipids, believes that ‘reducing the amount of saturated fats in the diet and reducing weight are the most effective ways of lowering cholesterol levels’.

Allium Sativum

Linn.

Family: Liliaceae, Alliaceae.

Habitat: Native to Central Asia. Cultivated all over India.

English: Garlic.

Ayurvedic: Lashuna, Rasona, Yavaneshta, Ugragandha, Ma- haushadh, Arishta.

Unani: Seer, Lahsun.

Siddha/Tamil: Ullippoondu, Vellaip- pondu.

Action: Antibiotic, bacteriostatic, fungicide, anthelmintic, antithrom- bic, hypotensive, hypoglycaemic, hypocholesterolaemic. Also used for upper respiratory tract infections and catarrhal conditions.

Key application: As a supportive to dietary measures for elevated levels of lipids in blood; as a preventive measure for age-dependent vascular changes. (German Commission E, ESCOP, WHO, The British Herbal Pharmacopoeia.) Also as an antimicrobial. (The British Herbal Pharmacopoeia). Garlic has been shown to be effective in respiratory infections and catarrhal conditions. (The British Herbal Compendium.)

The Ayurvedic Pharmacopoeia ofIn- dia indicates the use of the bulb as a brain tonic in epilepsy and psychic disorders.

Heavy consumption of garlic prior to surgery led to increased clotting time or reduced platelet aggregation (in human case reports). Garlic tablets at a dose of 400 mg twice daily for 12 weeks reduced platelet aggregation 59% compared with placebo in 80 patients (in human clinical study). (Francis Brinker.)

Garlic cloves are high in sulphur- containing amino acids known as al- liin (no taste, no smell, no medicinal action). With crushing or chewing alli- in comes into contact with the enzyme alliinase. Alliinase, in less than 6 s, transforms alliin into allicin (strongly medicinal), which breaks down into a number of sulphur compounds including ajoene, vinyldithin and diallyl disulfide, and trisulfide. The antibiotic effect is attributed to allicin; hypogly- caemic effect to allicin and allylpro- phyldisulphide (also to S-allyl cysteine sulfoxide); anticarcinogenic activity to diallyl monosulfide; platelet aggregation inhibitory effect to diallyl-di- and tri-sulphides. Ajoene inactivated human gastric lipase, which is involved in digestion and absorption of dietary fats.

Diallyltetra, penta-, hexa- and hep- tasulphides are potential antioxidants.

Chylomicrons

These are organized blobs of fats, synthesized in the submucosa of the small intestine out of dietary fats, phospholipids, specialized proteins and cholesterol, carried out of the intestinal tract by the lymph, and slowly released into the bloodstream. In the capillaries, the triglycerides inside the chylomicrons, recognized by their protein markers, are absorbed into the tissues for fuel or storage, and the outside cholesterol and phospholipid transport-cover continues through the blood to be absorbed by the liver for its use. This sideways approach takes (ideally) a large part of dietary fats into the lymph back alleys, spreading their release into the bloodstream out over many hours, thereby avoiding short-term blood fat and liver fat overload. To synthesize the maximum amount of dietary fats into chylomicrons, you need well-organized emulsification and digestion of lipids by the gallbladder and pancreas.... chylomicrons

Eye, Disorders Of

Arcus senilis The white ring or crescent which tends to form at the edge of the cornea with age. It is uncommon in the young, when it may be associated with high levels of blood lipids (see LIPID).

Astigmatism (See ASTIGMATISM.)

Blepharitis A chronic in?ammation of the lid margins. SEBORRHOEA and staphylococcal infection are likely contributors. The eyes are typically intermittently red, sore and gritty over months or years. Treatment is di?cult and may fail. Measures to reduce debris on the lid margins, intermittent courses of topical antibiotics, steroids or systemic antibiotics may help the sufferer.

Blepharospasm Involuntary closure of the eye. This may accompany irritation but may also occur without an apparent cause. It may be severe enough to interfere with vision. Treatment involves removing the source of irritation, if present. Severe and persistent cases may respond to injection of Botulinum toxin into the orbicularis muscle.

Cataract A term used to describe any opacity in the lens of the eye, from the smallest spot to total opaqueness. The prevalence of cataracts is age-related: 65 per cent of individuals in their sixth decade have some degree of lens opacity, while all those over 80 are affected. Cataracts are the most important cause of blindness worldwide. Symptoms will depend on whether one or both eyes are affected, as well as the position and density of the cataract(s). If only one eye is developing a cataract, it may be some time before the person notices it, though reading may be affected. Some people with cataracts become shortsighted, which in older people may paradoxically ‘improve’ their ability to read. Bright light may worsen vision in those with cataracts.

The extent of visual impairment depends on the nature of the cataracts, and the ?rst symptoms noticed by patients include di?culty in recognising faces and in reading, while problems watching television or driving, especially at night, are pointers to the condition. Cataracts are common but are not the only cause of deteriorating vision. Patients with cataracts should be able to point to the position of a light and their pupillary reactions should be normal. If a bright light is shone on the eye, the lens may appear brown or, in advanced cataracts, white (see diagram).

While increasing age is the commonest cause of cataract in the UK, patients with DIABETES MELLITUS, UVEITIS and a history of injury to the eye can also develop the disorder. Prolonged STEROID treatment can result in cataracts. Children may develop cataracts, and in them the condition is much more serious as vision may be irreversibly impaired because development of the brain’s ability to interpret visual signals is hindered. This may happen even if the cataracts are removed, so early referral for treatment is essential. One of the physical signs which doctors look for when they suspect cataract in adults as well as in children is the ‘red re?ex’. This is observable when an ophthalmoscopic examination of the eye is made (see OPHTHALMOSCOPE). Identi?cation of this red re?ex (a re?ection of light from the red surface of the retina –see EYE) is a key diagnostic sign in children, especially young ones.

There is no e?ective medical treatment for established cataracts. Surgery is necessary and the decision when to operate depends mainly on how the cataract(s) affect(s) the patient’s vision. Nowadays, surgery can be done at any time with limited risk. Most patients with a vision of 6/18 – 6/10 is the minimum standard for driving – or worse in both eyes should

E

bene?t from surgery, though elderly people may tolerate visual acuity of 6/18 or worse, so surgery must be tailored to the individual’s needs. Younger people with a cataract will have more demanding visual requirements and so may opt for an ‘earlier’ operation. Most cataract surgery in Britain is now done under local anaesthetic and uses the ‘phaco-emulsi?cation’ method. A small hole is made in the anterior capsule of the lens after which the hard lens nucleus is liqui?ed ultrasonically. A replacement lens is inserted into the empty lens bag (see diagram). Patients usually return to their normal activities within a few days of the operation. A recent development under test in the USA for children requiring cataract operations is an intra-ocular ?exible implant whose magnifying power can be altered as a child develops, thus precluding the need for a series of corrective operations as happens now.

Chalazion A ?rm lump in the eyelid relating to a blocked meibomian gland, felt deep within the lid. Treatment is not always necessary; a proportion spontaneously resolve. There can be associated infection when the lid becomes red and painful requiring antibiotic treatment. If troublesome, the chalazion can be incised under local anaesthetic.

Conjunctivitis In?ammation of the conjunctiva (see EYE) which may affect one or both eyes. Typically the eye is red, itchy, sticky and gritty but is not usually painful. Redness is not always present. Conjunctivitis can occasionally be painful, particularly if there is an associated keratitis (see below) – for example, adenovirus infection, herpetic infection.

The cause can be infective (bacteria, viruses or CHLAMYDIA), chemical (e.g. acids, alkalis) or allergic (e.g. in hay fever). Conjunctivitis may also be caused by contact lenses, and preservatives or even the drugs in eye drops may cause conjunctival in?ammation. Conjunctivitis may addtionally occur in association with other illnesses – for example, upper-respiratory-tract infection, Stevens-Johnson syndrome (see ERYTHEMA – erythema multiforme) or REITER’S SYNDROME. The treatment depends on the cause. In many patients acute conjunctivitis is self-limiting.

Dacryocystitis In?ammation of the lacrimal sac. This may present acutely as a red, painful swelling between the nose and the lower lid. An abscess may form which points through the skin and which may need to be drained by incision. Systemic antibiotics may be necessary. Chronic dacryocystitis may occur with recurrent discharge from the openings of the tear ducts and recurrent swelling of the lacrimal sac. Obstruction of the tear duct is accompanied by watering of the eye. If the symptoms are troublesome, the patient’s tear passageways need to be surgically reconstructed.

Ectropion The lid margin is everted – usually the lower lid. Ectropion is most commonly associated with ageing, when the tissues of the lid become lax. It can also be caused by shortening of the skin of the lids such as happens with scarring or mechanical factors – for example, a tumour pulling the skin of the lower lid downwards. Ectropion tends to cause watering and an unsightly appearance. The treatment is surgical.

Entropion The lid margin is inverted – usually the lower lid. Entropion is most commonly associated with ageing, when the tissues of the lid become lax. It can also be caused by shortening of the inner surfaces of the lids due to scarring – for example, TRACHOMA or chemical burns. The inwardly directed lashes cause irritation and can abrade the cornea. The treatment is surgical.

Episcleritis In?ammation of the EPISCLERA. There is usually no apparent cause. The in?ammation may be di?use or localised and may affect one or both eyes. It sometimes recurs. The affected area is usually red and moderately painful. Episcleritis is generally not thought to be as painful as scleritis and does not lead to the same complications. Treatment is generally directed at improving the patient’s symptoms. The in?ammation may respond to NON-STEROIDAL ANTI-INFLAMMATORY DRUGS (NSAIDS) or topical CORTICOSTEROIDS.

Errors of refraction (Ametropia.) These will occur when the focusing power of the lens and cornea does not match the length of the eye, so that rays of light parallel to the visual axis are not focused at the fovea centralis (see EYE). There are three types of refractive error: HYPERMETROPIA or long-sightedness. The refractive power of the eye is too weak, or the eye is too short so that rays of light are brought to a focus at a point behind the retina. Longsighted people can see well in the distance but generally require glasses with convex lenses for reading. Uncorrected long sight can lead to headaches and intermittent blurring of vision following prolonged close work (i.e. eye strain). As a result of ageing, the eye becomes gradually long-sighted, resulting in many people needing reading glasses in later life: this normal process is known as presbyopia. A particular form of long-sightedness occurs after cataract extraction (see above). MYOPIA(Short sight or near sight.) Rays of light are brought to a focus in front of the retina because the refractive power of the eye is too great or the eye is too short. Short-sighted people can see close to but need spectacles with concave lenses in order to see in the distance. ASTIGMATISMThe refractive power of the eye is not the same in each meridian. Some rays of light may be focused in front of the retina while others are focused on or behind the retina. Astigmatism can accompany hypermetropia or myopia. It may be corrected by cylindrical lenses: these consist of a slice from the side of a cylinder (i.e. curved in one meridian and ?at in the meridian at right-angles to it).

Keratitis In?ammation of the cornea in response to a variety of insults – viral, bacterial, chemical, radiation, or mechanical trauma. Keratitis may be super?cial or involve the deeper layers, the latter being generally more serious. The eye is usually red, painful and photophobic. Treatment is directed at the cause.

Nystagmus Involuntary rhythmic oscillation of one or both eyes. There are several causes including nervous disorders, vestibular disorders, eye disorders and certain drugs including alcohol.

Ophthalmia In?ammation of the eye, especially the conjunctiva (see conjunctivitis, above). Ophthalmia neonatorum is a type of conjunctivitis that occurs in newborn babies. They catch the disease when passing through an infected birth canal during their mother’s labour (see PREGNANCY AND LABOUR). CHLAMYDIA and GONORRHOEA are the two most common infections. Treatment is e?ective with antibiotics: untreated, the infection may cause permanent eye damage.

Pinguecula A benign degenerative change in the connective tissue at the nasal or temporal limbus (see EYE). This is visible as a small, ?attened, yellow-white lump adjacent to the cornea.

Pterygium Overgrowth of the conjunctival tissues at the limbus on to the cornea (see EYE). This usually occurs on the nasal side and is associated with exposure to sunlight. The pterygium is surgically removed for cosmetic reasons or if it is thought to be advancing towards the visual axis.

Ptosis Drooping of the upper lid. May occur because of a defect in the muscles which raise the lid (levator complex), sometimes the result of ageing or trauma. Other causes include HORNER’S SYNDROME, third cranial nerve PALSY, MYASTHENIA GRAVIS, and DYSTROPHIA MYOTONICA. The cause needs to be determined and treated if possible. The treatment for a severely drooping lid is surgical, but other measures can be used to prop up the lid with varying success.

Retina, disorders of The retina can be damaged by disease that affects the retina alone, or by diseases affecting the whole body.

Retinopathy is a term used to denote an abnormality of the retina without specifying a cause. Some retinal disorders are discussed below. DIABETIC RETINOPATHY Retinal disease occurring in patients with DIABETES MELLITUS. It is the commonest cause of blind registration in Great Britain of people between the ages of 20 and 65. Diabetic retinopathy can be divided into several types. The two main causes of blindness are those that follow: ?rst, development of new blood vessels from the retina, with resultant complications and, second, those following ‘water logging’ (oedema) of the macula. Treatment is by maintaining rigid control of blood-sugar levels combined with laser treatment for certain forms of the disease – in particular to get rid of new blood vessels. HYPERTENSIVE RETINOPATHY Retinal disease secondary to the development of high blood pressure. Treatment involves control of the blood pressure (see HYPERTENSION). SICKLE CELL RETINOPATHY People with sickle cell disease (see under ANAEYIA) can develop a number of retinal problems including new blood vessels from the retina. RETINOPATHY OF PREMATURITY (ROP) Previously called retrolental ?broplasia (RLF), this is a disorder affecting low-birth-weight premature babies exposed to oxygen. Essentially, new blood vessels develop which cause extensive traction on the retina with resultant retinal detachment and poor vision. RETINAL ARTERY OCCLUSION; RETINAL VEIN OCCLUSION These result in damage to those areas of retina supplied by the affected blood vessel: the blood vessels become blocked. If the peripheral retina is damaged the patient may be completely symptom-free, although areas of blindness may be detected on examination of ?eld of vision. If the macula is involved, visual loss may be sudden, profound and permanent. There is no e?ective treatment once visual loss has occurred. SENILE MACULAR DEGENERATION (‘Senile’ indicates age of onset and has no bearing on mental state.) This is the leading cause of blindness in the elderly in the western world. The average age of onset is 65 years. Patients initially notice a disturbance of their vision which gradually progresses over months or years. They lose the ability to recognise ?ne detail; for example, they cannot read ?ne print, sew, or recognise people’s faces. They always retain the ability to recognise large objects such as doors and chairs, and are therefore able to get around and about reasonably well. There is no e?ective treatment in the majority of cases. RETINITIS PIGMENTOSAA group of rare, inherited diseases characterised by the development of night blindness and tunnel vision. Symptoms start in childhood and are progressive. Many patients retain good visual acuity, although their peripheral vision is limited. One of the characteristic ?ndings on examination is collections of pigment in the retina which have a characteristic shape and are therefore known as ‘bone spicules’. There is no e?ective treatment. RETINAL DETACHMENTusually occurs due to the development of a hole in the retina. Holes can occur as a result of degeneration of the retina, traction on the retina by the vitreous, or injury. Fluid from the vitreous passes through the hole causing a split within the retina; the inner part of the retina becomes detached from the outer part, the latter remaining in contact with the choroid. Detached retina loses its ability to detect light, with consequent impairment of vision. Retinal detachments are more common in the short-sighted, in the elderly or following cataract extraction. Symptoms include spots before the eyes (?oaters), ?ashing lights and a shadow over the eye with progressive loss of vision. Treatment by laser is very e?ective if caught early, at the stage when a hole has developed in the retina but before the retina has become detached. The edges of the hole can be ‘spot welded’ to the underlying choroid. Once a detachment has occurred, laser therapy cannot be used; the retina has to be repositioned. This is usually done by indenting the wall of the eye from the outside to meet the retina, then making the retina stick to the wall of the eye by inducing in?ammation in the wall (by freezing it). The outcome of surgery depends largely on the extent of the detachment and its duration. Complicated forms of detachment can occur due to diabetic eye disease, injury or tumour. Each requires a specialised form of treatment.

Scleritis In?ammation of the sclera (see EYE). This can be localised or di?use, can affect the anterior or the posterior sclera, and can affect one or both eyes. The affected eye is usually red and painful. Scleritis can lead to thinning and even perforation of the sclera, sometimes with little sign of in?ammation. Posterior scleritis in particular may cause impaired vision and require emergency treatment. There is often no apparent cause, but there are some associated conditions – for example, RHEUMATOID ARTHRITIS, GOUT, and an autoimmune disease affecting the nasal passages and lungs called Wegener’s granulomatosis. Treatment depends on severity but may involve NON-STEROIDAL ANTI-INFLAMMATORY DRUGS (NSAIDS), topical CORTICOSTEROIDS or systemic immunosuppressive drugs.

Stye Infection of a lash follicle. This presents as a painful small red lump at the lid margin. It often resolves spontaneously but may require antibiotic treatment if it persists or recurs.

Sub-conjunctival haemorrhage Haemorrhage between the conjunctiva and the underlying episclera. It is painless. There is usually no apparent cause and it resolves spontaneously.

Trichiasis Inward misdirection of the lashes. Trichiasis occurs due to in?ammation of or trauma to the lid margin. Treatment involves removal of the patient’s lashes. Regrowth may be prevented by electrolysis, by CRYOTHERAPY to the lid margin, or by surgery.

Importance: Castor is a perennial evergreen shrub. The Sanskrit name erandah describes the property of the drug to dispel diseases. It is considered as a reputed remedy for all kinds of rheumatic affections. They are useful in gastropathy such as gulma, amadosa, constipation, inflammations, fever, ascitis, strangury, bronchitis, cough, leprosy, skin diseases, vitiated conditions of vata, colic, coxalgia and lumbago. The leaves are useful in burns, nyctalopia, strangury and for bathing and fermentation and vitiated conditions of vata, especially in rheumatoid arthritis, urodynia and arthralgia. Flowers are useful in urodynia and arthralgia and glandular tumours. Seeds are useful in dyspepsia and for preparing a poultice to treat arthralgia. The oil from seeds is a very effective purgative for all ailments caused by vata and kapha. It is also recommended for scrotocele, ascites, intermittent fever, gulma, colonitis, lumbago, coxalgia and coxitis (Warrier et al, 1996). Oil is also used for soap making. Fresh leaves are used by nursing mothers in the Canary Island as an external application to increase the flow of milk. Castor oil is an excellent solvent of pure alkaloids and as such solutions of atropine, cocaine, etc. is used in ophthalmic surgery. It is also dropped into the eye to remove the after-irritation caused by the removal of foreign bodies.

Distribution: It is a native of N. E. tropical Africa. It is found throughout India, cultivated and found wild upto 2400m.

Botany: Ricinus communis Linn. belongs to the family Euphorbiaceae. It is a monoecious evergreen shrub growing upto 4m. Leaves are alternate, palmatifid, 6-10 lobed, each 1- nerved with many lateral nerves and peltate. Lobes are lanceolate, thinly pubescent below, margin serrate and apex acuminate. Paniculate racemes are terminal with male flowers below, female ones above. Perianth is cupular, splitting into 3-5 lobes, laceolate, valvate, margin inrolled and acuminate. Filaments of stamen are connate and repeatedly branched with divergent anther cells. Sepals are 5, sub-equal, lanceolate, valvate and acute. Ovary is globose, echinate, 3-locular with 3 ovules and pendulous. Styles are 3, stout, papillose, stigmatiferous. Capsules are 3-lobed and prickly with oblong seeds having smooth testa and marbled, shiny and carunculate. R. bronze King and R. africanus are two good garden varieties which are known as Italian and East Indian Castors, respectively (Mathew, 1983, Grieve and Leyel, 1992).

Agrotechnology: Castor is cultivated both in the plains and the hills. As it has deep root system it is hardy and capable of resisting drought. It does not withstand waterlogging and frost. It requires hard dry climate for proper development of fruits and seeds. It requires a well- drained soil, preferably sandy loam or loamy sand. High soil fertility is of less importance as compared to the good physical condition of the soil. It cannot tolerate alkalinity. It is generally grown in red loamy soils, black soils and alluvial soils. The plant is seed propagated. The seed rate required is 5-12 kg/ha (pure crop) and 3 kg/ha (mixed crop). Seeds are to be sown on a hot bed early in March. When the plants come up individual plant is to be planted in a separate pot filled with light soil and plunged into a fresh hot bed. The young plants are to be kept in glass houses till early June where they are hardened and kept out. The suitable season of growing is kharif season. The crop is usually sown in April and planting is done in early July. The land is to be ploughed 2-3 times with the onset of rains and is repeated after rain. The spacing recommended is 60X90cm in case of pure crop but it is seldom cultivated pure. It is usually grown mixed with crops such as jowar, arhar, chilly, groundnut, cowpea, cotton, etc. 10-15t FYM/ha and 50kg N, 50kg P2O5 and 20kg K2O/ha will be sufficient. Addition of neem cake is beneficial as it increases oil content. There should be sufficient moisture in the field at the time of sowing. A month after planting, weeding and earthing up is to be done. The plant is attacked by hairy caterpillar, castor semi - looper, castor seed caterpillar, etc. which can be managed by integrated pest management measures. The leaf blight disease occurring in castor can be controlled by spraying with Bordeaux mixture 2-3 times at 15 days interval. Harvesting of ripe fruits can be done from the end of November till the end of February. The fruit branches are picked when they are still green to avoid splitting and scattering of the seeds. The pods are to be heaped up in the sun to dry. Then the seeds are to be beaten with stick and winnowed. Roots, leaves, flowers, seeds and oil constitute the economic parts. The average yield is 500-600kg/ha (Thakur, 1990).

Properties and activity: The beancoat yielded lupeol and 30-norlupan-3 -ol-20-one. Roots, stems and leaves contain several amino acids. Flowers gave apigenin, chlorogenin, rutin, coumarin and hyperoside. Castor oil is constituted by several fatty acids (Husain et al, 1992). Seed coat contained 1. 50-1. 62% lipids and higher amounts of phosphatides and non-saponifiable matter than seed kernel. Fresh leaves protected against liver injury induced by carbon tetra chloride in rats while cold aqueous extract provided partial protection (Rastogi et al, 1991). Root and stem is antiprotozoal and anticancerous. Root, stem and seed are diuretic. The roots are sweet, acrid, astringent, thermogenic, carminative, purgative, galactagogue, sudorific, expectorant and depurative. Leaves are diuretic, anthelmintic and galactagogue. Seeds are acrid, thermogenic, digestive, cathartic and aphrodisiac. Oil is bitter, acrid, sweet, antipyretic, thermogenic and viscous (Warrier et al, 1996). Castor oil forms a clean, light- coloured soap, which dries and hardens well and is free from smell. The oil varies much in activity. The East Indian is the more active, but the Italian has the least taste. Castor oil is an excellent solvent of pure alkaloids. The oil furnishes sebacic acid and caprylic acid. It is the most valuable laxative in medicines. It acts in about 5 hours, affecting the entire length of the bowel, but not increasing the flow of bile, except in very large doses. The mode of its action is unknown. The oil will purge when rubbed into the skin (Grieve and Leyel, 1992).... castor

Nicotinic Acid

Nicotinic acid is a member of the vitamin B complex. It is essential for human nutrition, the normal daily requirement for an adult being about 15–20 mg. A de?ciency of nicotinic acid is one of the factors in the etiology of PELLAGRA, and either nicotine acid or NICOTINAMIDE is used in the treatment of this condition. Nicotinic acid also reduces the concentration of blood lipids (see HYPERLIPIDAEMIA).... nicotinic acid

Maca Tea - A Libido Enhancer

Maca tea has been recognized for its nutritional properties and for being a libido enhancer. Maca plant, also known as the “Peruvian ginseng”, is an herb that grows in the high Andes of Bolivia and Peru for thousands of years. It is related to the turnip and the radish, having green and fragrant tops that lie along the ground. Maca has been used in Peru as a remedy to enhance energy and sexual function. The constituents of maca root are basically minerals such as calcium, potassium, magnesium, zinc, phosphorus and iron; sterols, lipids, carbohydrates, fiber, proteins and amino acids. How To Make Maca Tea Maca tea has a sweet taste, similar to butterscotch. To brew maca tea you will need an herbal tea of your choice to combine it with the maca powder. Prepare the herbal tea and after 1-2 minutes, add a teaspoon of maca powder and stir the mixture. To really enhance the flavor, you can add milk or honey. Tea connoisseurs recommend Soya milk. Maca Tea Benefits
  • Helps providing energy without over-stimulating the body’s systems.
  • Enhances libido and helps in the treatment of erectile dysfunction.
  • Increases the production of sperm.
  • Helps relieving the symptoms of menopause.
  • Strengthens your immune system.
  • Balances and stabilizes the body’s cardiovascular, nervous, muscular and lymphatic systems.
Maca Tea Side Effects In toxicity studies, maca tea showed no adverse pharmacological effects. However, maca root contains iodine, which can lead to side effects such as thyroid disease. Maca root is also high in glucosinolates and in case of over consumption, combined with low-iodine diet, can cause goiter. It can also cause hives and fatigue to people that are allergic to the constituents of maca tea. Maca Tea is a wonderful tea with many health benefits. It is ideal for incresing your libido and boosting your immune system! Try to avoid over consumption in order not to experience any of its side effects!... maca tea - a libido enhancer

Fatty Acid

an organic acid with a long straight hydrocarbon chain and an even number of carbon atoms. Fatty acids are the fundamental constituents of many important lipids, including *triglycerides. Some fatty acids can be synthesized by the body; others, the *essential fatty acids, must be obtained from the diet. Examples of fatty acids are palmitic acid, oleic acid, and stearic acid. See also fat; saturated fatty acid; unsaturated fatty acid.... fatty acid

Globulin

n. one of a group of simple proteins that are soluble in dilute salt solutions and can be coagulated by heat. A range of different globulins is present in the blood (the serum globulins, including alpha (?), beta (?), and *gamma (?) globulins).

See also hormone-binding globulins.... globulin

Glutathione

n. a peptide containing the amino acids glutamic acid, cysteine, and glycine. It functions as a *coenzyme in several oxidation-reduction reactions. Glutathione serves as an *antioxidant: it reacts with potentially harmful oxidizing agents and is itself oxidized (see also selenium). This is important in ensuring the proper functioning of proteins, haemoglobin, membrane lipids, etc. High levels of glutathione in the blood are associated with longevity.... glutathione

Menopause

This is the term applied to the cessation of MENSTRUATION at the end of reproductive life. Usually it occurs between the ages of 45 and 50, although it may occur before the age of 30 or after the age of 50. It can be a psychologically disturbing experience which is quite often accompanied by physical manifestations. These include hot ?ushes, tiredness, irritability, lack of concentration, palpitations, aching joints and vaginal irritation. There may also be loss of libido (sex drive). Most women can and do live happy, active lives through the menopause, the length of which varies considerably.

One of the major problems of the menopause which does not give rise to symptoms until many years later is osteoporosis (see BONE, DISORDERS OF). After the menopause, 1 per cent of the bone is lost per annum to the end of life. This is a factor in the frequency of fractures of the femur in elderly women as a result of osetoporosis, but it can be prevented by hormone replacement therapy (see below).

Hormone replacement therapy (HRT) This term has become synonymous with the scienti?cally correct term ‘OESTROGENS replacement therapy’ to signify the treatment of menopausal symptoms and signs with oestrogens, now usually combined with PROGESTOGEN. Oestrogen and combined treatment relieve the short-term symptoms such as hot ?ushes, sweats and vaginal dryness. Atrophic vaginitis and vulvitis (shrinking of the tissues of VULVA and VAGINA due to fall in natural oestrogen levels) also usually respond to treatment with oestrogens.

Cyclical therapy is necessary to avoid abnormal bleeding in women who have reached the menopause. If oestrogens are given alone, there is an increased risk of endometrial hyperplasia (overgrowth of the ENDOMETRIUM) which may lead to endometrial cancer, so these are restricted to women who have had a hysterectomy and are no longer at risk. Other women can be given oestrogen-progestogen combinations.

There is good evidence that oestrogen alone or in combination can prevent the bone-loss associated with the menopause by reducing the demineralisation of bone which normally occurs after the menopause; and, if it is started early and continued for years, it may prevent the development of osteoporosis. Oestrogen is far more e?ective than calcium supplements and has been shown greatly to reduce fractures affecting the spine, wrists and legs after the age of 50.

However, HRT is no longer licensed for ?rst-line treatment to prevent osteoporosis, as increased risk of stroke, breast cancer and coronary heart disease cannot justify treatment for long periods – unless the woman has severe menopausal symptoms. HRT is recommended for short-term use only in menopausal women whose lives are inconvenienced by vasomotor instability (severe ?ushes, etc.) or vaginal atrophy, although the latter may respond to local oestrogen treatment – creams or pessaries. In terms of oestrogenic activity, natural oestrogen such as oestradiol, oestrone and oestriol are more appropriate for HRT than synthetic oestrogens like ethinyloestradiol, mestranol and diethylstilboestrol.

Many experts believe that controversy surrounding the risks and bene?ts of HRT have been settled by a large randomised trial (the Women’s Health Initiative), published in 2003, which showed that combined treatment increases the risk of breast tumours, stroke and coronary heart disease (in the ?rst year). Oestrogen alone (given to women who have had a hysterectomy) also increases the risk of stroke. Five years of combined treatment may double the risk of breast cancer, and the heart-disease risk is nearly doubled during the ?rst year of use. This is in spite of the bene?cial effects of HRT on blood lipids. However, there are others who consider that di?erent dose combinations of di?erent hormones may one day prove bene?cial, so research continues.

HRT can also provoke minor adverse effects such as breast tenderness, ?uid retention, leg cramps and nausea. The risk of abnormal blood clotting means that HRT is not normally recommended for women who smoke heavily or have had THROMBOSIS, severe HYPERTENSION, stroke or liver disease. HRT has, however, brought symptomatic bene?ts to many menopausal women, who can then justify taking the other increased risks – only fully understood since the large trial results were published.

As the evidence stands at present, careful consideration of each woman’s medical history and the severity of her menopausal symptoms is necessary in deciding what combination of drugs should be given and for how long. In general, the indications should be severe menopausal symptoms that can be controlled by the lowest dose for the shortest time. Using HRT to alleviate mild symptoms, or to prevent future bone loss, is probably of insu?cient bene?t to counter the other risks described above.... menopause

Hypertriglyceridaemia

n. an excess of *triglyceride lipids in the serum, which can be caused by a genetic predisposition with or without a high-fat diet (see also lipoprotein lipase), excessive alcohol intake, or poorly controlled diabetes mellitus.

Prunus Avium

Linn.

Family: Rosaceae.

Habitat: Native to Eurasia; cultivated in Kashmir, Kumaon and Himachal Pradesh.

English: Sweet Cherry.

Ayurvedic: Elavaaluka, Elaya, Harivaaluka.

Folk: Gilaas, Krusbal.

Action: Fruit stalks—diuretic, antiinflammatory, astringent, used for oedema, inflammation of urinary tract, cystitis, nephritis, urinary retention.

The stems contain salicylic acid, organic acids tannins and potassium salts. Protocatechuic, p-coumaric, fer- ulic and diferculic acids have been identified in the shoots.

The fruit contains salicylates and cyanogenic glycosides, and vitamin A, B1 and C. Sugars consist mainly of glucose and fructose, with sucrose as a minor component. Malic acid is the principal acid, small amounts of citric, tartaric and succinic acids are also reported. The lipids of the fruit pulp contain cis-vaccenic acid.

Pravastatin

n. a drug used to reduce abnormally high levels of cholesterol and other lipids in the blood (see statin). Its actions and side-effects are similar to those of *atorvastatin.... pravastatin

Surfactant

n. a wetting agent. Surfactants can be added to materials used in dentistry to reduce surface tension and so improve flow. Pulmonary surfactant, secreted by type II *pneumocytes, is a complex mixture of compounds (including lipids, protein, and carbohydrates) that prevents the air sacs (alveoli) of the lungs from collapsing by reducing surface tension. In its absence, as in the immature lungs of premature babies, *atelectasis and *respiratory distress syndrome will develop.... surfactant

Rouleau

A group of red blood cells arranged together like a roll of coins, usually only noticed on a slide under a microscope. Since red blood cells in a reasonably healthy person should have a mutually repelling membrane charge, this means that something like an inflammatory response or an elevation of liver-synthesized lipids (LDLs and VLDLs) is occurring. Inflammation makes the blood “sticky,” and the lipids from the liver lower the charges. Remember, of course, that I am talking about subclinical imbalances...such things as rouleau can accompany some pretty gnarly diseases. Our kind of rouleau can give you a headache or make your hands and feet cold because it’s hard to push rolls of coins through little bitty capillaries.... rouleau

Tea For Cellulite

Cellulite is a painless affection which consists of the fat layer growth. This is not very unusual and many women around the world suffer from it. Generally, cellulite is your body’s way of protecting your organism when you’re pregnant. On the other hand, you can develop cellulite from having a very unbalanced diet: unhealthy foods and drinks (sodas and fast food). Also, the lack of workout and exercise will slow your calories from burning, making them stick mostly to your hips and thighs. How Tea for Cellulite Works A Tea for Cellulite’s main purpose is to make your blood veins work properly and eliminate the lipids surplus. Also, their action implies veins dilatation and increased blood pressure so that your entire body will work to get rid of the unwanted fats. What you need to know about cellulite is that this is not regular fat and, at times, even thin women have it. Keeping a diet will not make it go away so don’t starve yourself to death! Efficient Tea for Cellulite When choosing a Tea for Cellulite, you must keep in mind a couple of facts: it must be very efficient and safe. Since having a cellulite will not hurt more than your feelings, alternative medicine practitioners advice against all pills that promise to work miracles on your body and recommend, instead, an herbal treatment. If you don’t know which teas to choose from, here’s a list to guide you on: - Horse Chestnut Tea – it has anti inflammatory properties. Its main active constituent, Aescin, improves your blood flow by decreasing the pore size of your capillary walls. This will make your skin look a lot smoother and reduce the cellulite level. - Ginkgo Biloba Tea – is a great vasodilator whose main goal is to improve circulation. This Tea for Cellulite will also stop cholesterol level from enhancing and it can be used to treat memory loss, stress, anxiety, headaches and anemia. However, don’t drink more than 3 cups per day or you’ll get diarrhea. - Green Tea – has blood thinning properties, so you must avoid it at all costs in case you’re already on regular blood thinners. A cup of Green Tea per day will also improve your general health and bring relief in case you’re suffering from infertility, anemia, headaches or stress. However, don’t take it if you’re on menopause or menstruation in order to avoid stomach irritations and uterine contractions. - Dandelion Tea – will enhance your liver’s ability to process lipids faster and energize your entire body. However, this Tea for Cellulite is also a strong diuretic and purgative so you may want to avoid it if you suffer from diarrhea or upset stomach. Also, too much dandelion tea might cause urinary tract infections. Tea for Cellulite Side Effects When taken properly, these teas are generally safe. However, exceeding the number of cups recommended per day may weaken your digestive and nervous systems and lead to vomiting, nausea, headaches and even hallucinations. Before starting a treatment based on a Tea for Cellulite, talk to your doctor in order to find out which are the risks. Don’t take any of these teas if you’re pregnant, breastfeeding, on blood thinners, anticoagulants or preparing for a surgery. Children shouldn’t be allowed to take an herbal treatment since there is no study to prove how safe it is for them. But if you have the green light from your doctor and nothing could interfere with your Tea for Cellulite cure, choose a tea that fits best your needs and enjoy its health benefits!... tea for cellulite

Tinospora Cordifolia

(Willd.) Miers ex Hook. f. & Thoms.

Family: Menispermaceae.

Habitat: Tropical India and the Andamans.

Ayurvedic: Guduuchi, Gudu- uchikaa, Guluuchi, Amrita, Am- ritaa, Amritalataa, Amritavalli, Chinnaruuhaa, Chinnodbhavaa, Madhuparni, Vatsaadani, Tantrikaa, Kundalini. Guduuchi sattva (starch).

Unani: Gilo, Gulanchaa. Sat-e-Gilo (starch).

Siddha: Seenil, Amrida-valli.

Folk: Giloya.

Action: Herb—antipyretic, an- tiperiodic, anti-inflammatory, antirheumatic, spasmolytic, hypo- glycaemic, hepatoprotective. Water extract increases urine output. Stem juice—prescribed in high fever; decoction in rheumatic and bilious fevers. Aqueous extract of the plant—fabrifuge. Starch—antacid, antidiarrhoeal and antidysenteric.

The Ayurvedic Pharmacopoeia of India, along with other therapeutic applications, recommends the dried stems in jaundice, anaemia, polyuria and skin diseases.

The stem contains alkaloidal constituents, including berberine; bitter principles, including columbin, chas- manthin, palmarin and tinosporon, tinosporic acid and tinosporol.

The drug is reported to possess one- fifth of the analgesic effect of sodium salicylate. Its aqueous extract has a high phagocytic index.

Alcoholic extract of the stem shows activity against E. coli. Active principles were found to inhibit in vitro the growth of Mycobacterium tuberculosis.

Oral administration of alcoholic extract of the root resulted in a significant reduction in blood and urine glucose and in lipids in serum and tissues of alloxan diabetic rats. (Phytother Res. 2003 17 (4), 410-3.)

A significant reduction in levels of SGOT, SGPT, ALP and bilirubin were observed following T. cordifolia treatment during CCl4 intoxication in mature rats. (J. Toxicol Sci. 2002, 27 (3), 139-46.) The plant extract showed in vitro inactivating activity in Hepatitis- B surface antigen. (Indian Drugs, 1993, 30, 549.)

A new hypoglycaemic agent was isolated from the plant; it was found to be 1,2-substituted pyrrolidine.

The starch from roots and stem, used in chronic diarrhoea and dysentery, contains a polysaccharide having 1-4 glucan with occasional branching points.

Dosage: Stem—3-6 g powder; 2030 g for decoction. (API, Vol. I.)... tinospora cordifolia

Trigonella Foenum-graecum

Linn.

Family: Papilionaceae; Fabaceae.

Habitat: Widely cultivated in many parts of India.

English: Fenugreek.

Ayurvedic: Methikaa, Methi, Vastikaa, Selu, Methini, Dipani, Bahupatrikaa, Bodhaini, Gand- haphala.

Unani: Hulbaa, Methi.

Siddha/Tamil: Vendhayam.

Action: Seeds—used in loss of appetite, flatulence, dyspepsia, colic; diarrhoea, dysentery; enlargement of liver and spleen; and as a lactagogue and puerperal tonic.

Key application: German Commission E reported secretolytic, hypermic and mild antiseptic activity of the seed. The British Herbal Pharmacopoeia reported its actions as demulcent and hy- poglycaemic. ESCOP and WHO monographs indicate the use of seeds in adjuvant therapy for diabetes mellitus, anorexia, also in hypercholesterolemia.

The seeds gave alkaloids, including trigonelline, gentianine and carpaine; saponins, based mainly on the sa- pogenins, diosgenin and its isomer yamogenin, gitogenin and tigogenin; flavonoids, including vitexin and its glycosides and esters and luteolin; a volatile oil in small quantities. The mucilage (25-30%) is mostly a galac- tomannan.

A C-steroidal sapogenin peptide ester, fenugreekine, exhibited hypogly- caemic activity.

About 80% of the total content of free amino acids in the seeds is present as 4-hydroxyisoleucine, which appears to directly stimulate insulin. (Eur J Pharmacol, 390, 2000; Natural Medicines Comprehensive Database, 2007.)

Saponin rich extracts reduce blood levels of the cholesterol. The fibrous fraction of seeds also causes a reduction in blood lipids.

The aqueous extract is demulcent, promoted healing of gastric ulcers produced experimentally in rats and exhibited a smooth muscle relaxing effect in rabbits without affecting either the heart or blood pressure.

Fenugreek has been reported to stimulate the liver microsomal cy- tochrome P450 dependent aryl hy- droxylase and cytochrome b5 in rats; increased bile secretion has also been observed.

Fenugreek extract containing trigo- nelline and trigonellic acid maybe used as a hair growth stimulant.

Dosage: Seed—3-5 g powder. (CCRAS.)... trigonella foenum-graecum

Triticum Aestivum

Linn.

Family: Gramineae; Poaceae.

Habitat: Cultivated as a food crop mainly in Punjab, Haryana, Uttar Pradesh., Madhya Pradesh, Maharashtra, Bihar and Rajasthan.

English: Wheat.

Ayurvedic: Godhuuma.

Folk: Gehun.

Action: Wheat germ oil is rich in tocopherol (vitamin E) content, total tocopherols 1897 mcg/g, alpha tocopherol 67%. The presence of ergosterol (provitamin D) has also been reported.

Wheat germ is also used for its minerals, proteins and lipid contents. Germ proteins are rich in lysine (5.285.55 g/100 g protein) and possess high biological value (94%) and protein efficiency ratio (2.9).

Wheat germ contains haemaggluti- nating and antipyretic factors, but these are destroyed by toasting. It also contains haemoproteins, possessing per- oxidase activity.

In adult rats, addition of wheat germ (7%) to a high fat (cholesterol) diet significantly decreased VLDL-cholesterol and VLDL-triglycerides and increased the HDL-cholesterol after-7 weeks of feeding.

Bran oil contains tocopherols, but major part of them (68%) is in epsilon form; alpha-tocopherol forms only 11% of the total.

Gluten lipids, associated with gluten, contain a high percentage of linoleic acid; lowering of serum cholesterol level has been observed in experiments (lipid-free gluten is devoid of cholesterol-lowering effect).

Sensitivity to gluten has also been reported (even when whole wheat flour was used).... triticum aestivum

Xanthoma

(Plural: xanthomata.) A deposit of fatty material in the skin, subcutaneous fat and tendons. The presence of a xanthoma may be the ?rst sign that a person has primary or secondary HYPERLIPIDAEMIA – a raised concentration of lipids (see LIPID) in the blood. This can lead to ATHEROMA, and appropriate clinical and laboratory examinations should be done to determine the diagnosis and treatment.

When fatty deposits occur in various parts of the body – skin, brain, cornea, internal organs and tendons – the condition is called xanthomatosis. Treatment is of the underlying conditions, an important aim being to lower the concentrations of fats in the body.

Xanthomata have a variety of manifestations which may point to the underlying cause. These include:

Eruptive Eruptive yellow papules on the buttocks.

Plane Yellow plaques or macules in the skin.

Tuberous Nodules on the elbows or knees.

Tendinous Subcutaneous nodules ?xed to tendons, particularly those on the back of the ?ngers and the ACHILLES TENDON.... xanthoma

Coronary Heart Disease

The cause of: coronary occlusion, coronary blockage, coronary thrombosis. A heart attack occurs when a coronary artery becomes blocked by swellings composed, among other things, of cholesterol. Such swellings may obstruct the flow of blood leading to a blood clot (thrombus). Cholesterol is a major cause of CHD.

Coronary thrombosis is more common in the West because of its preference for animal fats; whereas in the East fats usually take the form of vegetable oils – corn, sunflower seed, sesame, etc. Fatty deposits (atheroma) form in the wall of the coronary artery, obstructing blood-flow. Vessels narrowed by atheroma and by contact with calcium and other salts become hard and brittle (arterio-sclerosis) and are easily blocked. Robbed of oxygen and nutrients heart muscle dies and is replaced by inelastic fibrous (scar) tissue which robs the heart of its maximum performance.

Severe pain and collapse follow a blockage. Where only a small branch of the coronary arterial tree is affected recovery is possible. Cause of the pain is lack of oxygen (Vitamin E). Incidence is highest among women over 40 who smoke excessively and who take The Pill.

The first warning sign is breathlessness and anginal pain behind the breastbone which radiates to arms and neck. Sensation as if the chest is held in a vice. First-line agent to improve flow of blood – Cactus.

For cholesterol control target the liver. Coffee is a minor risk factor.

Measuring hair calcium levels is said to predict those at risk of coronary heart disease. Low hair concentrations may be linked with poor calcium metabolism, high aortic calcium build-up and the formation of plagues. (Dr Allan MacPherson, nutritionist, Scottish Agricultural College, Ayr, Scotland)

Evidence has been advanced that a diagonal ear lobe crease may be a predictor for coronary heart disease. (American Journal of Cardiology, Dec. 1992)

Tooth decay is linked to an increased risk of coronary heart disease and mortality, particularly in young men. (Dr Frank De Stefano, Marshfield Medical Research Foundation, Wisconsin, USA) Treatment. Urgency. Send for doctor or suitably qualified practitioner. Absolute bedrest for 3 weeks followed by 3 months convalescence. Thereafter: adapt lifestyle to slower tempo and avoid undue exertion. Stop smoking. Adequate exercise. Watch weight.

Cardiotonics: Motherwort, Hawthorn, Mistletoe, Rosemary. Ephedra, Lily of the Valley, Broom.

Cardiac vasodilators relax tension on the vessels by increasing capacity of the arteries to carry more blood. Others contain complex glycosides that stimulate or relax the heart at its work. Garlic is strongly recommended as a preventative of CHD.

Hawthorn, vasodilator and anti-hypertensive, is reputed to dissolve deposits in thickened and sclerotic arteries BHP (1983). It is believed to regulate the balance of lipids (body fats) one of which is cholesterol.

Dupuytren’s Contracture

The Thatcher Finger. Fibrosis of the palm of the hand leading to deformity. Inability to straighten the ring and little finger due to fixed flexion. A tightened sinew. High serum fat levels are present, the disease affecting men from the age of 20 and women after the menopause.

“It is believed that oxidation of the lipids by free radicals (which are also present in high numbers in patients who have Dupuytren’s contracture) produces toxins which kill fibroblast cells in the palmar fascia. The surrounding tissue overreacts by producing many more fibroblasts, a bit like callous formation after a wound. The rapid increase in fibrous tissue leads to the contracture. This explains why the contracture is so common among patients with diabetes, epilepsy and alcoholism – serum lipid levels are raised in all these groups . . . However, the disorder occurs only if the patient has a genetic predisposition to the disease.” (Mr Paul Sanderson, Orthopaedic Surgeon, Wrightington Hospital, Wigan, in the Journal of Bone and Joint Surgery, Nov. 1992)

Treatment. Directed towards prevention. Same as for HYPERLIPIDAEMIA.

Hyperlipidaemia

Presence in the blood of excess lipids (fatty substances) including cholesterol, often a forerunner of arterial disease, coronary thrombosis, strokes. Related to diabetes and heart disease. There is an inherited form giving rise to family history of coronary disease at an early age.

Causes. Diet of too much animal fat, smoking, overweight, little exercise.

Symptoms. Same as those for ischaemic heart disease, acute pancreatitis, indigestion, abdominal pain. Alternatives. Hawthorn berries, Lime flowers, Goat’s Rue. Garlic – raw bulb with salads or 2-3 capsules at night. Herb Purslane (Portulaca oleracae): rich in EFA’s (essential fatty acids) in general, and EPA in particular.

Garlic powder significantly reduces serum cholesterol and triglyceride levels in hyperlipidaemia. (German Association of General Practitioners, Study Group on Phytotherapy)

Guar gum. Lowers serum fat levels, body weight and blood pressure: see entry. Add Hawthorn for angina; Goat’s Rue for diabetes; Ispaghula seeds (Regulan) for intestinal and bowel health and to reduce blood-fats.

Fenugreek seeds. Lowers blood cholesterol levels in healthy people and in diabetics. Contain galacto- mannan which aids fat digestion.

Diet. Low fat. High-complex carbohydrate diet. Sugar and refined starches raise but Oats and Bran lower cholesterol levels. High levels reduced by oleic acid (Olive oil). French research workers claim three apples a day can lower plasma and liver cholesterol levels by as much as 30 per cent. The effect is believed to be due to vegetable fibre, especially pectin. Those who stopped eating their three apples after the trial showed a return to higher levels. Replace unsaturated with vegetable polyunsaturated fats. Two or three fatty fish meals weekly to prevent clumping of platelets. Linseed, Grape juice, Artichokes. See entry – OILY FISH.

Supplement: Nicotinic acid.

Stop smoking. Limit intake of alcohol. ... hyperlipidaemia

Atherosclerosis

Accumulation of cholesterol and other fatty substances (lipids) in the walls of arteries, causing them to narrow. Atherosclerosis can affect arteries in any area of the body and is a major cause of stroke, heart attack (see myocardial infarction), and poor circulation in the legs. The arteries become narrowed when fatty substances, such as cholesterol, that are carried in the blood accumulate on the inside lining of the arteries and form yellow deposits called atheroma. These deposits restrict blood flow through the arteries. In addition, the muscle layer of the artery wall becomes thickened, narrowing the artery even more. Platelets (tiny blood cells responsible for clotting) may collect in clumps on the surface of the deposits and initiate the formation of blood clots. A large clot may completely block the artery, resulting in the organ it supplies being deprived of oxygen.

There are usually no symptoms in the early stages of atherosclerosis. Later, symptoms are caused by reduced or total absence of a blood supply to the organs supplied by the affected arteries. If the coronary arteries, which supply the heart muscle, are partially blocked, symptoms may include the chest pain of angina. If there is complete blockage in a coronary artery, a sudden, often fatal, heart attack may occur. Many strokes are a result of atherosclerosis in the arteries that supply blood to the brain. If atherosclerosis affects the leg arteries, the 1st symptom may be cramping pain when walking due to poor blood flow to the leg muscles. If the condition is associated with an inherited lipid disorder (see hyperlipidaemias), fatty deposits may develop on tendons or under the skin in visible lumps.

The risk of developing atherosclerosis is determined largely by the level of cholesterol in the bloodstream, which depends on dietary and genetic factors. Athersclerosis is most common in Western countries, where most people eat a diet high in fat. Some disorders such as diabetes mellitus can be associated with a high cholesterol level regardless of diet. Blood flow through an artery can be investigated by angiography or Doppler ultrasound scanning.

The best treatment for atherosclerosis is to prevent it from progressing by following a healthy lifestyle. This includes eating a low-fat diet, not smoking, exercising regularly, and maintaining the recommended weight for height. These measures lead to a lower-than-average risk of developing significant atherosclerosis. People found to have high blood cholesterol but who are otherwise in good health will be advised to adopt a low-fat diet. They may also be given drugs that decrease blood cholesterol levels (see lipid-lowering drugs). For people who have had a heart attack, research has shown that there may be a benefit in lowering blood cholesterol levels, even if the level is within the average range for healthy people.

People who have atherosclerosis and are experiencing symptoms of the condition may be prescribed a drug such as aspirin to reduce the risk of blood clots forming on the damaged artery lining.

Surgical treatment such as coronary angioplasty (see angioplasty, balloon) may be recommended for those people thought to be at high risk of severe complications. If blood flow to the heart is severely obstructed, a coronary bypass operation to restore blood flow may be carried out.... atherosclerosis

Fats And Oils

Nutrients that provide the body with its most concentrated form of energy. Fats, which are also called lipids, are compounds containing chains of carbon and hydrogen with very little oxygen. Chemically, fats consist mostly of fatty acids combined with glycerol. They are divided into 2 main groups, saturated and unsaturated, depending on the proportion of hydrogen atoms. If the fatty acids contain the maximum possible quantity of hydrogen, the fats are saturated. If some sites on the carbon chain are unoccupied by hydrogen, they are unsaturated; when many sites are vacant, they are polyunsaturated. Monounsaturated fats are unsaturated fats with only one site that could take an extra hydrogen. Animal fats, such as those in meat and dairy products, are largely saturated, whereas vegetable fats tend to be unsaturated.

Fats are usually solid at room temperature; oils are liquid. The amount and types of fat in the diet have important implications for health. A diet containing a large amount of fat, particularly saturated fat, is linked to an increased risk of atherosclerosis and subsequent heart disease and stroke.

Some dietary fats, mainly triglycerides (combinations of glycerol and 3 fatty acids), are sources of the fat-soluble vitamins A, D, E, and K and of essential fatty acids. Triglycerides are the main form of fat stored in the body. These stores act as an energy reserve and also provide insulation and a protective layer for delicate organs. Phospholipids are structural fats found in cell membranes. Sterols, such as cholesterol, are found in animal and plant tissues; they have a variety of functions, often being converted into hormones or vitamins.

Dietary fats are first emulsified by bile salts before being broken down by lipase, a pancreatic enzyme. They are absorbed via the lymphatic system before entering the bloodstream.Lipids are carried in the blood bound to protein; in this state they are known as lipoproteins. There are 4 classes of lipoprotein: very low-density lipoproteins (VLDLs), low-density lipoproteins (LDLs), high-density lipoproteins (HDLs), and chylomicrons. LDLs and VLDLs contain large amounts of cholesterol, which they carry through the bloodstream and deposit in tissues. HDLs pick up cholesterol and carry it back to the liver for processing and excretion. High levels of LDLs are associated with atherosclerosis, whereas HDLs have a protective effect. (See also nutrition.)... fats and oils

Cell

n. the basic unit of all living organisms, which can reproduce itself exactly (see mitosis). Each cell is bounded by a cell membrane of lipids and protein, which controls the passage of substances into and out of the cell. Cells contain *cytoplasm, in which are suspended a *nucleus and other structures (*organelles) specialized to carry out particular activities in the cell (see illustration).

Complex organisms are built up of millions of cells that are specially adapted to carry out particular functions. The process of cell differentiation begins early on in the development of the embryo and cells of a particular type (e.g. blood cells, liver cells) always give rise to cells of the same type. Each cell has a particular number of *chromosomes in its nucleus. The sex cells (sperm and ova) always contain half the number of chromosomes of all the other cells of the body (see meiosis); at fertilization a sperm and ovum combine to form a cell with a complete set of chromosomes that will develop into the embryo.... cell
