Ricinus communis-ஆமணாக்குச்செடி




The castor oil plant, Ricinus communis, is a species of flowering plant in the spurge family, Euphorbiaceae. It belongs to a monotypic genus, Ricinus, and subtribe, Ricininae. The evolution of castor and its relation to other species are currently being studied using modern genetic tools.
Its seed is the castor bean which, despite its name, is not a true bean. Castor is indigenous to the southeastern Mediterranean Basin, Eastern Africa, and India, but is widespread throughout tropical regions (and widely grown  in Malaysia and elsewhere as an ornamental plant).

Castor seed is the source of castor oil, which has a wide variety of uses. The seeds contain between 40% and 60% oil that is rich in triglycerides, mainly ricinolein. The seed contains ricin, a toxin, which is also present in lower concentrations throughout the plant.

An unrelated plant species, Fatsia japonica, is similar in 

appearance and known as the false castor oil

The leaves have Anti-vatha properties.The leaves can either be given as decoction or surasam.
The leaves are made into small pieces,then fried in castoroil and used for formentation in case of arthritis over the swollen and painful areas.
The leaves are heated and applied over the breast as a bandage to induce milk secretion in case of lactating mothers.
For painful abdomen due to constipation , amenorrhoea etc ,castor oil is gently applied externally over lower abdomen.Also the heated leaves of this plant should be externally applied over this area.
The roots are crushed and prepared as decoction and given for 3-5 days in case of pricking pain over axilla and increased vatha condition , lumbago,diseases of abdomen,pain around urinary bladder,
The oil prepared from seeds is castor oil.This oil is used to induce purgation in case of constipation,intesinal worms in children,eczema and dermatosis.
The dried seed powder is given in dose of about 1 to 2 gm in rheumatism, lumbago, piles, constipation, diseases of liver, spleen and sciatica etc.
For increased iyam or kapha conditions,cough,bronchial asthma etc, 2 parts of castor oil and 1 part of honey is mixed well and given internally to induce purgation and produce relief.

Though The Us National National University has time to search about this medicinal plant. The Indian Siddha Medicine Has gone far away in using as Traditional Medicine

The ancient and modern medicinal uses of the castor bean plant, Ricinus communis L. (Euphorbiaceae), in about fifty countries worldwide, has been surveyed. The different medicinal uses are grouped separately in relation to their pharmacological action, whether real or presumed, within the various medical specialties. The results show an extensive use of this plant throughout the world and the authors suggest that further research should be carried out to determine the active principles present in the various parts of the plant.

The plant grows throughout the tropical areas of India. In tropical regions the tree reaches the height upto 10-12 metres, whereas, in temperate regions a slender, woody, branching bush reaches upto 1-2 metres in height. The leaves alternate, palmately lobed with seven serrate lobes. The flowers monoecious, male flowers shortly stalked and female ones, sessile. The fruits are blunt, greenish, tricoccus capsules. The seeds are ovoid, flattened, shining and pinkish-grey in colour.

The plant is classified into two types viz. white and red. The white variety is commonly used in medicine. The botanical name of  Castor Oil Plant  is Ricinus communis and it belongs to family Euphorbiaceae. The seeds contain 45% of fixed oil, which consists glycerides of ricinoleic, isoricinoleic, stearic and dihydroxystearic acids. The seeds have lipases and a crystalline alkaloid, ricinine. The leaves and the stem also contain ricinine. Detection of palmitic (1.2), stearic (0.7), arachidic (0.3), hexadecenoic (0.2), oleic (3.2), linoleic (3.4), linolenic (0.2), ricinoleic (89.4%) and dihydroxy stearic acids as esters in castor oil by GLC
