Key application: In occasional constipation; contraindicated in intestinal obstruction and acutely inflamed intestinal diseases, ulcerative colitis, appendicitis. (German Commission E, ESCOP, WHO.)The Ayurvedic Pharmacopoeia of India recommends the use of dried juice of leaves in dysmenorrhoea and diseases of the liver.Aloe vera improved the hypoglycaemic effect of glyburide (gliben- clamide) when one tablespoonful aloe juice was given orally in the morning and at bedtime to 36 diabetic patients for 42 days. The juice (same dose) showed antihyperglycaemic activity (independently). (Francis Brinker.)Anthraquinone glycosides, known as aloin, in small doses act as a tonic to the digestive system, and at higher doses become a strong purgative, as well as increase colonic secretions and peristaltic contractions. Resin fraction is also as important as aloin in cathartic action. In A. barbadensis the highest percentage of aloin is 21.8%.Aloe produces pelvic congestion and is used for uterine disorders, generally with Fe and carminatives. The pulp is used in menstrual suppressions.A molecule in the Aloe vera gel, ace- mannan, stimulates macrophages and releases immune system potentiators; enhances function of T cells and interferon production. Animal studies have shown promising results in sarcoma.The carboxypeptidase and salicylate components of Aloe gel can inhibit bradykinin, a pain-producing agent; C-glycosyl chromone appears to reduce topical inflammation. Aloe gel also slows or inhibits the synthesis of thromboxane, which may accelerate the healing of burns. (Natural Medicines Comprehensive Database, 2007.)Dosage: Leaf pulp juice—10-20 ml. (CCRAS.) Dried leaf pulp juice— 125-500 mg powder. (API Vol. I.)... aloe barbadensisFAMILY: Rutaceae
SYNONYMS: C. aurantium var. dulcis, C. aurantium var. sinensis, China orange, Portugal orange.
GENERAL DESCRIPTION: An evergreen tree, smaller than the bitter variety, less hardy with fewer or no spines. The fruit has a sweet pulp and non-bitter membranes. Another distinguishing feature is the shape of the leaf stalk: the bitter orange is broader and in the shape of a heart.
DISTRIBUTION: Native to China; extensively cultivated especially in America (California and Florida) and round the Mediterranean (France, Spain, Italy). The expressed oil is mainly produced in Israel, Cyprus, Brazil and North America; the distilled oil mainly comes from the Mediterranean and North America.
OTHER SPECIES: There are numerous cultivated varieties of sweet orange, for example Jaffa, Navel and Valencia. There are also many other subspecies such as the Japanese orange (C. aurantium var. natsudaidai). See also bitter orange.
HERBAL/FOLK TRADITION: A very nutritious fruit, containing vitamins A, B and C. In Chinese medicine the dried sweet orange peel is used to treat coughs, colds, anorexia and malignant breast sores. Li Shih-chen says: ‘The fruits of all the different species and varieties of citrus are considered by the Chinese to be cooling. If eaten in excess they are thought to increase the “phlegm”, and this is probably not advantageous to the health. The sweet varieties increase bronchial secretion, and the sour promote expectoration. They all quench thirst, and are stomachic and carminative.’.
ACTIONS: Antidepressant, anti-inflammatory, antiseptic, bactericidal, carminative, choleretic, digestive, fungicidal, hypotensive, sedative (nervous), stimulant (digestive and lymphatic), stomachic, tonic.
EXTRACTION: 1. Essential oil by cold expression (hand or machine) of the fresh ripe or almost ripe outer peel. 2. Essential oil by steam distillation of the fresh ripe or almost ripe outer peel. An oil of inferior quality is also produced by distillation from the essences recovered as a byproduct of orange juice manufacture. Distilled sweet orange oil oxidizes very quickly, and anti-oxidant agents are often added at the place of production. (An oil from the flowers is also produced occasionally called neroli Portugal or neroli petalae; an oil from the leaves is also produced in small quantities.)
SYNONYM: 1. A yellowy-orange or dark orange mobile liquid with a sweet, fresh fruity scent, richer than the distilled oil. It blends well with lavender, neroli, lemon, clary sage, myrrh and spice oils such as nutmeg, cinnamon and clove.
2. A pale yellow or colourless mobile liquid with a sweet, light-fruity scent, but little tenacity.
PRINCIPAL CONSTITUENTS: Over 90 per cent monoterpenes, mainly limonene. The cold expressed oil also contains bergapten, auraptenol and acids.
SAFETY DATA: Generally non-toxic (although ingestion of large amounts of orange peel has been known to be fatal to children); non-irritant and non-sensitizing (although limonene has been found to cause dermatitis in a few individuals). Distilled orange oil is phototoxic: its use on the skin should be avoided if there is danger of exposure to direct sunlight. However, there is no evidence to show that expressed sweet orange oil is phototoxic although it too contains coumarins.

Extensively used in all areas of the food and drinks industry (more so than the bitter orange oil). Used as the starting material for the isolation of naturallimonene.... orange, sweet
