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

Essential Oils

Volatile oils. Out of 250,000 flowering plants only 2,000 yield essential oils. Soluble in alcohol, colourless. Contained in plants, they are responsible for taste, aroma and medicinal action. Organic properties give the flower its scent. May be anti-bacterial, antispasmodic, sedative, expectorant, antiseptic, anti-inflammatory. The smell of a flower roughly conveys the potency of its oil. An example is menthol in the mint family.

Oils used in Phytotherapy: Almond, English Chamomile, Aniseed, Bergamot, Black Pepper, Buchu, Camphor, Cedarwood, Cloves, Coriander, Cypress, Eucalyptus, Geranium, Juniper, Lavender (French), Lavender (English), Lavender (Spanish), Lemon, Marjoram, Orange (sweet), Patchouli, Peppermint, Pine (Scots), Rosemary, Sage, Sandalwood, Thyme, Spearmint, St John’s Wort, Turpentine, Ylang Ylang.

Most oils are obtained by steam distillation. Being highly concentrated, internal use is by a few drops, diluted. About 30-40 are used medicinally; each having its own specific healing properties. Some are convenient as inhalants; a few drops on a tissue for relief of catarrh, colds, etc. Fragrant burners and electronic diffusers are available for vapour-inhalation. Bring to boil 2 pints water; allow to stand 3-4 minutes; sprinkle on the surface 5-10 drops Eucalyptus oil and with towel over head, inhale steam, 5-10 minutes.

Examples: (a) equal parts dilute oils of Thyme and Hypericum (acute middle ear inflammation) 3-4 drops injected into ear 2-3 times daily. (b) 10 drops oil Marjoram in bath water for cramp. Eucalyptus is a useful antibacterial; Cinnamon (anti-inflammatory), Juniper (urinary antiseptic), Orange blossom (anti- depressant), Lavender (sedative).

Essential oils should never be used neat, except as prescribed by a suitably qualified practitioner. While aromatherapists do not prescribe internally, Dr Paul Belaiche, one of France’s leading experts on essential oils, advises oral medication at a maximum daily dosage of 12 drops according to the oil. He advises drops on the tongue, on activated charcoal, in capsule form using a suitable excipient or vegetable oil, or mixed with a little honey. Anal injection has proved successful, (8-10 drops in 10ml vegetable oil) or suppositories made from 200-300mg (8-10 drops) essential oil to 2 grams of base per suppository. Oils should never be allowed to touch the eyes.

Capsules of Garlic oil may be inserted into the rectum for worms or prostate disorder. OR: 10 drops oil mixed with 10ml vegetable oil and injected with the aid of a pipette. Dilute oil of Thyme is used as a massage-rub for chest infections. Oil of Cloves is not only an antiseptic but an analgesic to assuage moderate dental pain. Volatile oils reflexly stimulate the medulla through the olfactory nerve, thus promoting appetite and flow of saliva. All stimulate production of white blood cells and thereby support the immune system.

Oils not used: Basil, Bitter Almonds, Boldo, Calamus, Horseradish, Mugwort, Mustard, Pennyroyal, Rue, Sassafras, Savin, Tansy, Thuja, Wormseed.

Oils not used in pregnancy: Bay, Buchu, Chamomile, Clary Sage, Cinnamon, Clove, Fennel, Hyssop, Juniper, Marjoram, Myrrh, Peppermint, Rose, Rosemary, Sage, Thyme. All other oils – half the normal amount.

Tea: 2-3 drops, selected oil, on teabag makes 3 cups tea.

Inhalant: 10 drops on tissue, or same amount in hot water to inhale steam.

Bath water: add: 10-15 drops.

Compress: 10-15 drops in half a cup (75ml) milk or water. Soak suitable material and apply.

Massage: 6 drops in two teaspoons ‘carrier’ vegetable oil (Almond, Peanut, Olive, etc).

Fragrant oils replace hospital smell.

Fish Oils

It is now accepted that oily fish is good for the heart, arthritis, skin disorders and some cases of chronic headache.

In Greenland, where much oily fish is eaten, heart disease is scarcely known. Each year over 200,000 people in Britain alone die of heart disease. Western affluence-diseases from a diet of excess saturated fat (from meat, butter, etc) may be reduced by modest amounts of oily fish.

A daily intake of 800 milligrams of essential fatty acids as contained in herring, mackerel, cod, etc., can play a decisive role in cardiac treatments. Such fish may be eaten twice weekly. On days when not taken, supplement with pure fish oil or fish oil capsules. As little as 1oz (30 grams) of mackerel, herring or other similar fish is sufficient.

When eating oily fish only twice a week a teaspoon of pure fish oil or dessertspoon cod liver oil daily is sufficient.

Labels of fish oils should be carefully studied for their DHA and EPA content in milligrams. Add together to a total 800 milligrams – average daily dose.

Fish oils can lower the level of triglycerides and reduce ‘stickiness’ of the blood – its tendency to clot and possibly block coronary vessels. As fish oil Vitamin A contains 10,000iu of Retinol, it should not be taken for extended periods without the advice of a practitioner. ... fish oils

Oils, Impregnated

 Properties of herbs may be extracted into an oil base, such as Olive or other vegetable oil in the proportion of 250g dried or 750g fresh herb to 1 pint (500ml) oil.

Bruise herbs with a rolling pin (double quantity for fresh herb). Add oil. Simmer in low heat until herbs change colour – about 1 hour. Strain into bottles.

Alternative. Place crushed herb, preferably flowers, in the oil in a wide-mouthed bottle or jar. Cover. Shake daily. After 3 days, strain off and replenish with fresh material. Repeat the process 3 or 4 times until the oil is saturated with essence of the flowers (or herb). Strain and bottle. Method suitable for Lavender, Rosemary, Bergamot, Rose petals, Mullein and Chamomile.

Sunflower oil is used in general practice, although Olive or other vegetable oil proves satisfactory. ... oils, impregnated

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.
