GENERAL DESCRIPTION: The almond tree grows to a height of about 7 metres and is popular as a garden tree due to its pinky-white blossom. It is botanically classified as a drupe.
DISTRIBUTION: Native to Western Asia and North Africa, it is now extensively cultivated throughout the Mediterranean region, Israel and California.
OTHER SPECIES: There are two main types of almond tree – bitter and sweet. The sweet almond does not produce any essential oil.
HERBAL/FOLK TRADITION: A ‘fixed’ oil commonly known as ‘sweet almond oil’ is made by pressing the kernels from both the sweet and bitter almond trees. Unlike the essential oil, this fixed oil does not contain any benzaldehyde or prussic acid, and has many medical and cosmetic uses. It is used as a laxative, for bronchitis, coughs, heartburn and for disorders of the kidneys, bladder and biliary ducts. It helps relieve muscular aches and pains, softens the skin and premotes a clear complexion.
ACTIONS: Anaesthetic, antispasmodic, narcotic, vermifuge (FFPA).
EXTRACTION: Essential oil by steam distillation from the kernels. The nuts are first pressed and macerated in warm water for 12 to 24 hours before the oil is extracted. It is during this process that the prussic acid is formed; it is not present in the raw seed. Most commercial bitter almond oil is rectified to remove all prussic acid, i.e. free from prussic acid (FFPA).
CHARACTERISTICS: Light colourless liquid with a characteristic ‘marzipan’ scent (FFPA).
PRINCIPAL CONSTITUENTS: Benzaldehyde (95 per cent), prussic acid (3 per cent).
SAFETY DATA: Prussic acid, also known as hydrocyanic acid or cyanide, is a well-known poison. Benzaldehyde is also moderately toxic.
AROMATHERAPY/HOME: USE None. ‘Should not be used in therapy either internally or externally.’2
OTHER USES: Bitter almond oil is no longer used for internal medication. Rectified bitter almond oil is used for flavouring foods, mainly confectionery; the most common uses are ‘almond essence’ and marzipan. The oil (FFPA) is increasingly being replaced by synthetic benzaldehyde in food flavourings.... almond, bitter
FAMILY: Rutaceae
SYNONYMS: C. vulgaris, C. bigaradia, Seville orange, sour orange bigarade (oil).
GENERAL DESCRIPTION: An evergreen tree up to 10 metres high with dark green, glossy, oval leaves, paler beneath, with long but not very sharp spines. It has a smooth greyish trunk and branches, and very fragrant white flowers. The fruits are smaller and darker than the sweet orange. It is well known for its resistance to disease and is often used as root stock for other citrus trees, including the sweet orange.
DISTRIBUTION: Native to the Far East, especially India and China, but has become well adapted to the Mediterranean climate. It also grows abundantly in the USA (California), Israel and South America. Main producers of the oil include Spain, Guinea, the West Indies, Italy, Brazil and the USA.
OTHER SPECIES: There are numerous different species according to location – oils from Spain and Guinea are said to be of superior quality.
HERBAL/FOLK TRADITION: ‘Oranges and lemons strengthen the heart, are good for diminishing the coagubility of the blood, and are beneficial for palpitation, scurvy, jaundice, bleedings, heartburn, relaxed throat, etc. They are powerfully anti-scorbutic, either internally or externally applied.’. The dried bitter orange peel is used as a tonic and carminative in treating dyspepsia.
In Chinese medicine the dried bitter orange and occasionally its peel are used in treating prolapse of the uterus and of the anus, diarrhoea, and blood in the faeces. Ingestion of large amounts of orange peel in children, however, has been reported to cause toxic effects.
ACTIONS: Anti-inflammatory, antiseptic, astringent, bactericidal, carminative, choleretic, fungicidal, sedative (mild), stomachic, tonic.
EXTRACTION: An essential oil by cold expression (hand or machine pressing) from the outer peel of the almost ripe fruit. (A terpeneless oil is also produced.) The leaves are used for the production of petitgrain oil; the blossom for neroli oil.
CHARACTERISTICS: A dark yellow or brownish-yellow mobile liquid with a fresh, dry, almost floral odour with a rich, sweet undertone.
PRINCIPAL CONSTITUENTS: Over 90 per cent monoterpenes: mainly limonene, myrcene, camphene, pinene, ocimene, cymene, and small amounts of alcohols, aldehydes and ketones.
SAFETY DATA: Phototoxic; otherwise generally non-toxic, non-irritant and non sensitizing. Limonene has been reported to cause contact dermatitis in some individuals.
AROMATHERAPY/HOME: USE See sweet orange.
OTHER USES: Used in certain stomachic, laxative and carminative preparations. Employed as a fragrance component in soaps, detergents, cosmetics, colognes and perfumes. Extensively used as a flavouring material, especially in liqueurs and soft drinks. Also utilized as a starting material for the isolation of naturallimonene.... orange, bitter
