FAMILY: Fabaceae (Leguminosae)
SYNONYMS: Copahu balsam, copaiba, copaiva, Jesuit’s balsam, Maracaibo balsam, para balsam.
GENERAL DESCRIPTION: Wild-growing tropical tree up to 18 metres high, with thick foliage and many branches. The natural oleoresin occurs as a physiological product from various Copaifera species. Not a ‘true’ balsam.
DISTRIBUTION: Native to north east and central South America. Mainly produced in Brazil; also Venezuela, Guyana, Surinam and Colombia.
OTHER SPECIES: Several Copaifera speices yield an oleoresin: the Venezuelan type ‘Maracaibo balsam’ has a low oil content, the Brazilian type ‘para balsam’ has a high oil content. See also Botanical Classification section.
HERBAL/FOLK TRADITION: Used for centuries in Europe in the treatment of chronic cystitis and bronchitis; also for treating piles, chronic diarrhoea and intestinal problems.
ACTIONS: Batericidal, balsamic, disinfectant, diuretic, expectorant, stimulant.
EXTRACTION: 1. The crude balsam is collected by drilling holes into the tree trunks; it is one of the most plentiful naturally occurring perfume materials. 2. An essential oil is obtained by dry distillation from the crude balsam. It is mainly the ‘para balsams’ with a high oil content (60–80 per cent), which are used for distillation.
CHARACTERISTICS: 1. The crude balsam is a viscous, yellowy-brown or greenish-grey liquid which hardens upon exposure to air with a mild, woody, slightly spicy odour. It blends well with styrax, amyris, lavandin, cedarwood, lavender, oakmoss, woods and spices. 2. The oil is a pale yellow or greenish mobile liquid with a mild, sweet, balsamic-peppery odour. It blends well with cananga, ylang ylang, vanilla, jasmine, violet and other florals.
PRINCIPAL CONSTITUENTS: Mainly caryophyllene.
SAFETY DATA: Relatively non-toxic, non-irritant, possible sensitization. Large doses cause vomiting and diarrhoea.
AROMATHERAPY/HOME: USE:
DIGESTIVE SYSTEM: Intestinal infections, piles.
Respiratory System: Bronchitis, chills, colds, coughs, etc.
Genito-Rinary System: Cystitis.
Nervous System: Stress-related conditons.
OTHER USES: The oleoresin is used in pharmaceutical products especially cough medicines and iuretics. The oil and crude balsam are extensively used as a fixative and fragrance component in all types of perfumes, soaps, cosmetics and detergents. The crude is also used in porcelain painting.

Development of such mechanical and biomechanical devices points the way to a much wider use of e?ective prostheses, enabling people who would previously have died or been severely handicapped to lead normal or near normal lives. The technical hazards that have already been overcome provide a sound foundation for future successes. Progress so far in producing prostheses should also ensure that organ replacement is free from the serious ethical problems that surround the use of genetic manipulation to cure or prevent serious diseases (see ETHICS).
Limbs These are best made to meet the individual’s requirements but can be obtained ‘o? the shelf’. Arti?cial joints normally comprise complex mechanisms to stimulate ?exion and rotation movements. Leg prostheses are generally more useful than those for arms, because leg movements are easier to duplicate than those of the arm. Modern electronic circuitry that enables nerve impulses to be picked up and converted into appropriate movements is greatly improving the e?ectiveness of limb prostheses.
Eyes Arti?cial eyes are worn both for appearance and for psychological reasons. They are made of glass or plastic, and are thin shells of a boat-shape, representing the front half of the eye which has been removed. The stump which is left has still the eye-muscles in it, and so the arti?cial eye still has the power of moving with the other. A glass eye has to be replaced by a new one every year. Plastic eyes have the advantage of being more comfortable to wear, being more durable, and being unbreakable. Research is taking place aimed at creating a silicon chip that stimulates the visual cortex and thus helps to restore sight to the blind.
Dental prostheses is any arti?cial replacement of a tooth. There are three main types: a crown, a bridge and a denture. A crown is the replacement of the part of a tooth which sticks through the gum. It is ?xed to the remaining part of the tooth and may be made of metal, porcelain, plastic or a combination of these. A bridge is the replacement of two or three missing teeth and is usually ?xed in place. The replacement teeth are held in position by being joined to one or more crowns on the adjacent teeth. A denture is a removable prosthesis used to replace some or all the teeth. The teeth are made of plastic or porcelain and the base may be of plastic or metal. Removable teeth may be held more ?rmly by means of implants.
Heart The surgical replacement of stenosed or malfunctioning heart-valves with metal or plastic, human or pig valves has been routinely carried out for many years. So too has been the insertion into patients with abnormal heart rhythms of battery-driven arti?cial pacemakers (see CARDIAC PACEMAKER) to restore normal function. The replacement of a faulty heart with an arti?cial one is altogether more challenging. The ?rst working attempt to create an arti?cial heart took place in the early 1980s. Called the Jarvik-7, it had serious drawbacks: patients had to be permanently connected to apparatus the size of an anaesthetic trolley; and it caused deaths from infection and clotting of the blood. As a result, arti?cial hearts have been used primarily as bridging devices to keep patients alive until a suitable donor heart for transplantation can be found. Recent work in North America, however, is developing arti?cial hearts made of titanium and dacron. One type is planted into the chest cavity next to the patient’s own heart to assist it in its vital function of pumping blood around the body. Another replaces the heart completely. Eventually, it is probable that arti?cial hearts will replace heart transplants as the treatment of choice in patients with serious heart disorders.
Liver Arti?cial livers work in a similar way to kidney dialysis machines (see DIALYSIS). Blood is removed from the body and passed through a machine where it is cleaned and treated and then returned to the patient. The core of the device comprises several thousand ?exible membrane tubules on which live liver cells (from pigs or people) have been cultured. There is an exchange of biological molecules and water with the ‘circulating’ blood, and the membrane also screens the ‘foreign’ cells from the patient’s immune system, thus preventing any antagonistic immune reaction in the recipient.
Nose The making of a new nose is the oldest known operation in plastic surgery, Hindu records of such operations dating back to 1,000 BC. Loss of a nose may be due to eroding disease, war wounds, gun-shot wounds or dog bites. In essence the operation is the same as that practised a thousand years before Christ: namely the use of a skin graft, brought down from the forehead. Alternative sources of the skin graft today are skin from the arm, chest or abdomen. As a means of support, the new nose is built round a graft of bone or of cartilage from the ear.... prosthesis

Perhaps the simplest base is lard or butter, as used by Maria Treben. 2 handfuls (4oz or 120g) finely chopped herbs are digested in 500g lard or butter. Heat gently one hour. Stand overnight. Should be sufficiently fluid next morning to filter through muslin or a wire-mesh strainer. Pour into jars. Very effective but its life is not more than a few weeks.
((a) Vaseline base. Dissolve vaseline. Place 1oz (handful) fresh herb (say . . . Chickweed) or tablespoon dried herb (or 2 teaspoons powder) in 7oz (100g) vaseline melted in low heat. Simmer gently 15 minutes, stirring all the time. Strain through a wire-mesh strainer while hot and pour into air-tight containers.
(b) Vaseline base. To incorporate essential oils; i.e. Oil of Eucalyptus 2ml; Oil of Pine 1ml; Oil of Peppermint 2ml; vaseline to 30 gram. Melt the vaseline. Add oils. Stir until cold. Makes a useful inhalant ointment applied directly to the frontal sinus areas, or inhaled from boiling water. (Fred Fletcher Hyde) (c) Mixed base, suitable for holding liquid extracts, tinctures. Ingredients: parts, Almond oil 12; Liquid Extract (say . . . Comfrey) 5; powdered gum Acacia 3; water (preferably distilled) to 100.
Method: Rub together a small equal amount of well-sieved Acacia powder and water to form a paste – best performed in a pestle and mortar. Add the Almond oil. Mix. Add liquid extract, tincture or oil slowly until a good consistency is reached. Slowly add remaining water and stir. Store in airtight glass jars.
(d) Olive and Beeswax base. Ingredients: 2oz beeswax; 16oz Olive oil.
Method: cut beeswax into slices and dissolve in the Olive oil on a low heat. Stir until all beeswax is dissolved. Place in a stone jar or pyrex vessel 12oz aerial parts of fresh herb material (Marigold, Plantain, Chickweed etc) or 4oz hard woody parts, roots or barks (Comfrey, Marshmallow, etc). Pour on the Olive oil and beeswax. Place in a warm oven for 3 hours; give an occasional stir. While still hot, strain through a wire-mesh strainer into pots. Store in a refrigerator. Where powders are used, the proportion is 2oz for every 16oz Olive oil.
((e) Coconut oil base. Dissolve 7 parts Coconut oil. Add 5 parts powdered herbs and 6 parts beeswax. Simmer gently 1 and a half hours. Strain through warm wire mesh strainer or muslin. Filter if necessary. Pour into jars.
(f) Pile ointment. Prepare, vaseline base. Add, Liquid Extract Pilewort 5 per cent, Liquid Extract Witch Hazel 5 per cent; Tincture Benzoin 5 per cent; Menthol 2 and a half per cent.
((g) Pain Reliever. Prepare, vaseline base. Add Menthol 2 per cent; Eucalyptus 2 per cent; Camphor 2 per cent; Oil of Mustard 0.2 per cent.
(h) Russian traditional. It is still common in country practice to simmer popular herbs (Marigold, Arnica, St John’s Wort) in butter, as above.
Preservatives. Length of life of above ointments is increased by addition of Benzoic acid, Nipagen, etc. Benzoinated lard was once a popular base used in pharmacy. Ointments containing volatile oils should be kept in porcelain or glass pots in preference to synthetic containers. All ointments should be stored out of the light and in a cool place.
