Composition The cellular components are red cells or corpuscles (ERYTHROCYTES), white cells (LEUCOCYTES and lymphocytes – see LYMPHOCYTE), and platelets.
The red cells are biconcave discs with a diameter of 7.5µm. They contain haemoglobin
– an iron-containing porphyrin compound, which takes up oxygen in the lungs and releases it to the tissue.
The white cells are of various types, named according to their appearance. They can leave the circulation to wander through the tissues. They are involved in combating infection, wound healing, and rejection of foreign bodies. Pus consists of the bodies of dead white cells.
Platelets are the smallest cellular components and play an important role in blood clotting (see COAGULATION).
Erythrocytes are produced by the bone marrow in adults and have a life span of about 120 days. White cells are produced by the bone
marrow and lymphoid tissue. Plasma consists of water, ELECTROLYTES and plasma proteins; it comprises 48–58 per cent of blood volume. Plasma proteins are produced mainly by the liver and by certain types of white cells. Blood volume and electrolyte composition are closely regulated by complex mechanisms involving the KIDNEYS, ADRENAL GLANDS and HYPOTHALAMUS.... blood

Besides these, there are always ozone, minerals and organic matter present in small and variable amounts, and more or less water vapour according to the weather. In the air of towns, sulphurous acid and sulphuretted hydrogen are important impurities derived from combustion. After air has been respired once, the oxygen falls by about 4 per cent and the carbonic acid rises to about 4 per cent, while organic matter and water vapour are greatly increased and the air rises in temperature. The cause of the discomfort felt in badly ventilated rooms and crowded halls is associated with the increase in the temperature and moisture of the air, but a high percentage of carbon dioxide may be present without causing any noticeable discomfort or appreciable quickening of the respiration. A combination of hot weather and emissions from vehicles and fossil-fuel combustion produces pollutants linked to a rise in the incidence of ASTHMA and other cardiorespiratory conditions. Falling levels of ozone in the upper atmosphere are also believed to contribute to global warming because ozone screens the earth from most of the sun’s harmful ultraviolet radiation.... air

It is a recurrent and paroxysmal disorder starting suddenly and ceasing spontaneously due to occasional sudden excessive rapid and local discharge of the nerve cells in the grey matter (cortex) of the BRAIN. Epilepsy always arises in this way from the brain, but its origin is often of microscopic size. It is diagnosed by the clinical symptoms based on the observations of witnesses. Its cause can sometimes be established by laboratory tests, and brain scanning. Fits can be the ?rst sign of a tumour, or follow a stroke, brain injury or infection, but in the large majority no underlying cause is found – so-called idiopathic epilepsy.
A single epileptic ?t is not epilepsy. Of those people who have a single seizure, a signi?cant minority (20 per cent) have no further attacks.
Major (generalised) seizures have a sudden, often unprovoked onset; the patient emits a cry, then falls to the ground, rigid, blue, and then twitching or jerking both sides of the body: the tonic-clonic convulsion. Drowsiness and confusion may last for some hours after recovering consciousness. Some experience a momentary warning (AURA): a smell, or sensation in the head or abdomen, vision, or déjà vu.
Partial seizures: focal motor (Jacksonian) begin with twitching of the angle of the mouth, the thumb, or the big toe. If the seizure discharge then spreads, the twitching or jerking spreads gradually through the limbs. Consciousness is preserved unless the seizure spreads to produce a secondary generalised ?t. In some attacks the eyes and head may turn, the arm may rise, and the body may turn, while some patients feel tingling in the limbs.
Complex partial seizures (temporal lobe epilepsy) The patient usually appears blank, vacant and may be unable to talk, or may mumble or chatter – though later they often have no memory of this period. They may be able to carry out complex tasks, taking o? gloves or clothes, and may smack their lips or rub repeatedly on one limb (automatisms). A sense of strangeness supervenes: unreality, or a feeling of having experienced it all before (déja vu). There may be a sense of panic. Strange unpleasant smells and tastes are olfactory and gustatory hallucinations. The visual hallucinations evoke complex scenes. An initial rising sense of warmth or discomfort in the stomach, or ‘speeding-up’ of thoughts are common psychomotor symptoms. All these strange symptoms are brief, disappearing within a few seconds or up to 3–4 minutes.
Minor seizures (petit mal) Attacks start in childhood. They last a few seconds. The child ceases what he or she is doing, stares, looks a little pale, and may ?utter the eyelids. The head may drop forwards. Attacks are commonly provoked by overbreathing. The child and parents may be unaware of the attacks
– ‘just daydreaming’. Major ?ts develop in one-third of subjects. By contrast with other types of epilepsy, the ELECTROENCEPHALOGRAM (EEG) is diagnostic.
Precautions Children with epilepsy should take normal school exercises and games, and can swim under supervision. Adults must avoid working at heights, with exposed dangerous machinery, and driving vehicles on public roads. Current legislation allows driving after two years of complete freedom from attacks during waking hours; those who for more than three years have had a history of attacks only while asleep may also drive.
Treatment identi?es, and avoids where possible, any factors (such as shortage of sleep or excessive ?uids) which aggravate or trigger attacks. If ?ts are very infrequent, treatment may not be recommended. However, frequent ?ts may be embarassing, may cause injury or may cause long-term brain damage so treatment is advisable. Anti-epileptic drugs are usually necessary for several years under medical supervision. Carbamazepine and sodium valproate are the most frequently prescribed. The dose is governed by the degree of control of ?ts and sometimes drug levels can be monitored by blood tests to check on dosage. Strict adherence to the drug schedule gives a reasonable chance of total suppression of ?ts, especially in younger patients whose ?ts have started recently. The table summarises anticonvulsant drugs in use. Interactions can occur between anti-epileptics and, if drug treatment is changed, the patient needs careful monitoring. In particular, abrupt withdrawal of a drug should be avoided as this may precipitate severe rebound seizures.
Indications First-choice drugs: Ethosuximide PM, JME Phenobarbitone M, P Phenytoin M, P, CP Carbamazepine M, P, CP Valproate M, PM, JME Second-line drugs: Primidone M, P, CP Clobazam M, CP Vigabatrin M, P, CP Lamotrigine M, P, CP Gabapentin M, P, CP Topirimate P
M = major generalised tonic-clonic; P = partial or focal; CP = complex partial (temporal lobe); PM = petit mal; JME = juvenile myoclonic epilepsy.
Anticonvulsant drugs
As all anticonvulsant drugs have an e?ect on the brain, it is not surprising that there may be side-effects, especially inolving alertness or behaviour. In each case careful assessment is necessary for doctor and patient to agree on the best compromise between stopping ?ts and avoiding ill-effects of medication.
Patients who have an epileptic seizure should not be restrained or have a gag or anything else placed in their mouths; nor should they be moved unless in danger of further injury. Any tight clothing around the neck should be loosened and, when the seizure has passed, the person should be placed in the recovery position to facilitate a return to consciousness (see APPENDIX 1: BASIC FIRST AID).

Avoid overstocking; some herbs lose their potency on the shelf in time, especially if exposed. Do not keep on a high shelf out of the way. Experts suggest a large box with a lid to protect its contents, kept in a cool dry place away from foods and other household items. Store mixtures containing Camphor separately elsewhere. Camphor is well-known as a strong antidote to medicinal substances. Keep all home-made ointments in a refrigerator. However harmless, keep all remedies out of reach of children. Be sure that all tablet containers have child-resistant tops.
Keep a separate box, with duplicates, permanently in the car. Check periodically. Replace all tablets when crumbled, medicines with changed colour or consistency. Always carry a large plastic bottle of water in the car for cleansing dirty wounds and to form a vehicle to Witch Hazel and other remedies. Label all containers clearly.

Medicines fall into three categories: POM (Prescription Only Medicines), P (Pharmacy Only), and OTC (Over The Counter). POM and P medicines must be prescribed by a registered medical practitioner and dispensed by a pharmacist. P medicines can be sold only by a registered pharmacist. Health stores are concerned with the OTC products, the sale of which is governed by S.I. Medicines General Sales List, Order 1980, No 1922.
All medicines and substances used as medicine bearing a medicinal claim on label or advertising material must be licenced. Without a licence it is not lawful for any person, in his business, to manufacture, sell, supply, export, or import into the United Kingdom any medicinal products unless some exemption is provided in the Act or subsequent regulations. The prefix ML, followed by the Manufacturer’s number must appear on the label together with the product licence number prefixed by the capitals PL. For example, if any person other than a pharmacist sells a medicinal product which claims to relieve indigestion or headache, but the label of which bears no licence number, that shopkeeper (and the manufacturer) will be breaking the law.
All foods are exempt from licencing provided no claims are made of medicinal benefits.
A special licence (manufacturer’s) is required by any person who manufactures or assembles a medicinal product. (Section 8) He must hold a Product Licence for every product he manufactures unless some special exemption is provided by the Act. He may of course act to the order of the product licence holder. (Section 23)
“Manufacture” means any process carried on in the course of making a product but does not include dissolving or dispersing the product in, or diluting or mixing it with some other substance used as a vehicle for the purpose of administering it. It includes the mixture of two or more medicinal products.
“Assembly” means enclosing a medicinal product in a container which is labelled before the product is sold or supplied, or, where the product is already enclosed in a container in which it is supplied, labelling the container before the product is sold or supplied in it. (Section 132)
From the practitioner’s point of view, herbal medicines are exempt from the Act and no licence is required.
The consulting herbalist in private practice who compounds his own preparations from medicinal substances may apply to the Medicines Control Agency, 1 Nine Elms Lane, London SW8 5NQ for a manufacturer’s licence to authorise mixture and assembly, for administration to their patients after he has been requested in their presence to use his own judgement as to treatment required. Products thus sold, will be without any written recommendation and not advertised in any way.
The “assembly” aspect of his licence refers to his ability to buy in bulk, repackage and label. Where he uses prepackaged products and does not open the packet, or relabel, a licence is not required. He will not be able to use terms, “Stomach mixture”, “Nerve mixture”, etc, implying cure of a specific condition.
It is necessary for the practitioner to have a personal consultation with his patient before making his prescription. Subsequent treatment may be supplied by a third person or by post at the discretion of the practitioner.
A licence is required where one or more non-herbal ingredients (such as potassium iodide, sodium citrate, etc) are included. Dispensing non-herbal remedies constitutes “manufacture” for which a licence is required. (MAL 24 (3))
The main thing the licensing authority looks for before granting a licence is evidence of safety. The manufacturers’ premises must be licenced. A wholesaler or distributor, also, must have a licence.
Where a product is covered by a Product Licence certain medicinal claims may be made. Where claims are made, the Act requires a warning to appear on the label worded: “If you think you have the disease to which this product refers, consult a registered medical practitioner before taking this product. If you are already receiving medical treatment, tell your doctor you are also taking this product.” (SI 41, s.5)
Labels of all medicines, tablets, etc, must carry the words: “Keep out of the reach of children”.
Under the Act it is illegal for medicines to be offered for sale for cancer, diabetes, epilepsy, glaucoma, kidney disease, locomotor ataxy, paralysis, sexually transmitted diseases and tuberculosis; these diseases to be treated by a registered medical practitioner only.
Definition of a herbal remedy. A “herbal remedy” is a medicinal product consisting of a substance produced by subjecting a plant or plants to drying, crushing or any other process, or of a mixture whose sole ingredients are two or more substances so produced, or of a mixture whose sole ingredients are one or more substances so produced and water or some other inert substances. (Section 132)
No licence is required for the sale, supply, manufacture or assembly of any such herbal remedy in the course of a business in which the person carrying on the business sells or supplies the remedy for administration to a particular person after being requested by or on behalf of that person, and in that person’s presence, to use his own judgement as to the treatment required. The person carrying on the business must be the occupier of the premises where the manufacture or assembly takes place and must be able to close them so as to exclude the public. (Section 12 (1))
No licence is required for the sale, supply, manufacture or assembly of those herbal remedies where the process to which the plant or plants are subjected consists only of drying, crushing or comminuting and the remedy is sold or supplied under a designation which only specifies the plant or plants and the process and does not apply any other name to the remedy; and without any written recommendation (whether by means of a labelled container or package or a leaflet or in any other way) as to the use of the remedy. (Section 12 (2)) This exemption does not apply to imported products. Except where a herbal product is supplied for a medicinal use, legally it is not even a medicinal product.
The 1968 Act has been a great step forward in the history of herbal medicine, The British Herbal Medicine Association and the National Institute of Medical Herbalists fought and won many special concessions. In years following the Act standards rose sharply. Practitioners enjoy a measure of recognition, with power to manufacture and dispense their own medicines and issue official certificates for incapacitation for work.

During an asthma attack, the muscle in the walls of the airways contracts, causing narrowing. The linings of the airways also become swollen and inflamed, producing excess mucus that can block the smaller airways.
In some people, an allergic response triggers the airway changes. This allergic type of asthma tends to occur in
childhood and may develop in association with eczema or certain other allergic conditions such as hay fever (see rhinitis, allergic). Susceptibility to these conditions frequently runs in families and may be inherited.
Some substances, called allergens, are known to trigger attacks of allergic asthma. They include pollen, house-dust mites, mould, and dander and saliva from furry animals such as cats and dogs. Rarely, certain foods, such as milk, eggs, nuts, and wheat, provoke an allergic asthmatic reaction. Some people with asthma are sensitive to aspirin, and taking it may trigger an attack.
When asthma starts in adulthood, there are usually no identifiable allergic triggers. The 1st attack is sometimes brought on by a respiratory infection.
Factors that can provoke attacks in a person with asthma include cold air, exercise, smoke, and occasionally emotional factors such as stress and anxiety. Although industrial pollution and exhaust emission from motor vehicles do not normally cause asthma, they do appear to worsen symptoms in people who already have the disorder. Pollution in the atmosphere may also trigger asthma in susceptible people.
In some cases, a substance that is inhaled regularly in the work environment can cause a previously healthy person to develop asthma. This type is called occupation asthma and is one of the few occupational lung diseases that is still increasing in incidence.
There are currently about 200 substances used in the workplace that are known to trigger symptoms of asthma, including glues, resins, latex, and some chemicals, especially isocyanate chemicals used in spray painting. However, occupational asthma can be difficult to diagnose because a person may be regularly exposed to a particular trigger substance for weeks, months, or even years before the symptoms of asthma begin to appear.
Asthmatic attacks can vary in severity from mild breathlessness to respiratory failure. The main symptoms are wheezing, breathlessness, dry cough, and tightness in the chest. In a severe attack, breathing becomes increasingly difficult, resulting in a low level of oxygen in the blood. This causes cyanosis (bluish discoloration) of the face, particularly the lips. Untreated, such attacks may be fatal.
There is no cure for asthma, but attacks can be prevented to a large extent if a particular allergen can be identified.
Treatment involves inhaled bronchodilator drugs (sometimes known as relievers) to relieve symptoms. When symptoms occur frequently, or are severe, inhaled corticosteroids are also prescribed. These drugs are used continuously to prevent attacks by reducing inflammation in the airways and are also known as preventers.
Other drug treatments include sodium cromoglicate and nedocromil sodium, which are useful in preventing exerciseinduced asthma.
A new group of drugs called leukotriene receptor antagonists may reduce the dose of corticosteroid needed to control the condition.
Theophylline or the inhaled anticholinergic drug ipratropium may also be used as bronchodilators.
An asthma attack that has not responded to treatment with a bronchodilator needs immediate assessment and treatment in hospital.... asthma
FAMILY: Myrtaceae
SYNONYMS: P. officinalis, pimento, pimenta, Jamaica pepper.
GENERAL DESCRIPTION: An evergreen tree which reaches about 10 metres high and begins to produce fruit in its third year. Each fruit contains two kidney-shaped green seeds which turn glossy black upon ripening.
DISTRIBUTION: Indigenous to the West Indies and South America, it is cultivated extensively in Jamaica, Cuba and, to a lesser degree, in Central America. Imported berries are distilled in Europe and America.
OTHER SPECIES: Four other varieties of pimento are found in Venezuela, Guyana and the West Indies which are used locally as spices.
HERBAL/FOLK TRADITION: Used for flatulent indigestion and externally for neuralgic or rheumatic pain. Pimento water is used as a vehicle for medicines which ease dyspepsia and constipation since it helps prevent griping pains. It is used extensively as a domestic spice – allspice is so called because it tastes like a combination of cloves, juniper berries, cinnamon and pepper.
ACTIONS: Anaesthetic, analgesic, anti-oxidant, antiseptic, carminative, muscle relaxant, rubefacient, stimulant, tonic.
EXTRACTION: Essential oil by steam distillation from 1. the leaves, and 2. the fruit. The green unripe berries contain more oil than the ripe berries, but the largest percentage of oil is contained in the shell of the fruit. An oleoresin from the berries is also produced in small quantities.
CHARACTERISTICS: 1. Pimenta leaf oil is a yellowish-red or brownish liquid with a powerful sweet-spicy scent, similar to cloves. 2. Pimenta berry oil is a pale yellow liquid with a sweet warm balsamic-spicy bodynote (middle note) and fresh, clean top note. It blends well with ginger, geranium, lavender, opopanax, labdanum, ylang ylang, patchouli, neroli, oriental and spicy bases.
PRINCIPAL CONSTITUENTS: Mainly eugenol, less in the fruit (60–80 per cent) than in the leaves (up to 96 per cent), also methyl eugenol, cineol, phellandrene and cryophyllene among others.
SAFETY DATA: Eugenol irritates the mucous membranes, and has been found to cause dermal irritation. Pimenta leaf and berry oil should therefore be used with care in low dilutions only.
AROMATHERAPY/HOME: USE:
Circulation, muscles and joints: Arthritis, fatigue, muscle cramp, rheumatism, stiffness etc. ‘Used in tiny amounts … in a massage oil for chest infections, for severe muscle spasm to restore mobility quickly, or where extreme cold is experienced.’1
Respiratory System: Chills, congested coughs, bronchitis.
Digestive System: Cramp, flatulence, indigestion, nausea.
Nervous System: Depression, nervous exhaustion, neuralgia, tension and stress.
OTHER USES: Used in aromatic carminative medicines; as a fragrance component in cosmetics and perfumes, especially soaps, aftershaves, spicy and oriental fragrances. Both leaf and berry oil are used extensively for flavouring foods, especially savoury and frozen foods, as well as alcoholic and soft drinks.... allspice
