It is commonly known as Bi ma in china, wooderboom in Denmark, Kiki in Egypt, Karchak in Iran, Aerand in India, Kastorka in Russia and Aderi in Nepal. The plant is native to southeastern Mediterranean Basin, Eastern Africa, and India. It is an erect, rapid-growing tender perennial that is grown in St. Louis as a warm weather annual. In certain parts of the U.S., including Missouri, it has escaped gardens and naturalized in fields, waste areas and along roadsides. Few of the popular common names of the plant are Castor bean, Castor, Castor oil plant, Castor-bean-plant, Castorbean, Palma-christi, wonder tree and Castor-Bean Tree. Genus name comes from the Latin word ricinus meaning a tick from the appearance of the seeds and specific epithet means common. The plant is so named because its seed looks like ‘tick’ and its occurrence is ‘common’ in many parts of the world. Every part of this plant is poisonous if ingested, mostly the seeds which consists of highly toxic ricin. Oil from the seeds has been used in a wide variety of industrial applications. Castor oil has application in the industry of varnishes and paints, nylon and other synthetic fibers today.

Plant Description

Castor is a fast-growing, evergreen glabrous, soft-woody shrub or small tree, often grown as annual, usually up to 6 to 15 feet (2-5 meters) tall with a strong tap root and prominent lateral roots. Shoots are glaucous, variously green, reddish or purplish. Occasional glands are found at nodes, petioles and main axes of inflorescences. Stipules are 1–3 cm long, connate. Stem is hollow, erect and grayish green in color when tender and as it ages the stem changes to brownish red color. The plant is found growing in thickets and waste places, disturbed sites, river bed, sand banks, in flood outs related with watercourses and along roadsides. The plant prefers semi-arid and arid soils with poor water retention ability. R. communis grows on sandy loam and clay with low nutrient soils, acidic to alkaline conditions. It does best on deep sandy loams and soil should also be well drained, and not saline.


Castor oil plant has large glossy, alternate leaves that are 15-45 centimeters (5.9-17.7 in) long. They are long-stalked, and palmate with 5-12 deep lobes with coarsely toothed segments. In some varieties leaves start off dark reddish purple or bronze when young, progressively changing to a dark green, sometimes with a reddish tinge, as they mature. The leaves of some other varieties are green practically from the start, whereas in yet others a pigment masks the green color of all the chlorophyll-bearing parts, leaves, stems and young fruit, so that they remain a dramatic purple-to-reddish-brown throughout the life of the plant.


The unisexual flowers appear in clusters at the end of the main stem in late summer. The flowers are usually green or red in color, depending on the variety of the plant. They have no petals.

Male flowers often appear towards the base of inflorescence and are yellowish-green with prominent creamy stamens. They appear in ovoid spikes up to 15 centimeters long. Female flowers appear on the tips of the spikes and can be distinguished by their prominent red stigma.


Castor flowers are followed by ellipsoid to globose oblong, spiny seed pods or capsules roughly 3 lobed and 1.5-2.5 cm long which contain an average of three seeds. Fruits are initially green turning to red or purplish red and drying to brown. When the fruit dries and split open, the seed is often ejected with considerable force. The seeds contained within the fruit are ellipsoid, 7–17 mm long, compressed, with a brittle, greyish, silvery or beige with mottled markings, shining seed coat and with distinct depressed conical caruncle at the base. The pod resembles a pinto bean.


Greek historian Herodotus first recognized the castor oil plant during 4th century B.C. and called it “Kiki.” He said that the oil from Kiki was used by the Egyptians for numerous purposes, such as providing fire for lamps and as an ingredient for ointments. By this point, the plant had already been introduced to Greece, where it is grown up to the present day under the same name. Later on, both Theophrastus and Dioscorides described the castor oil plant, and Dioscorides even gave an account of the process of extracting the oil from the plant. He highlighted that the seeds should be used externally as they were extremely purgative. There was also a mention of this plant in the Bible under the name “Kikajon”, in the Book of Jonah.

During the early middle Ages, the castor oil plant became popular in Europe for its medicinal qualities, mainly in the treatment of various skin diseases. Albertus Magnus, the bishop of Ratisbon, recorded and cultivated the plant in the middle 13th century, but the plant later fell out of favor and became less popular.

During the 18th century, castor oil and seeds required for European medicine were imported from Jamaica, and the name “castor” started to be used. Today it is planted throughout the world due to its amazing medicinal values and health promoting benefits.


A range of varieties have been selected for their leaf or flower/fruit colors, and for oil production. Some of the most common ornamental types include:

  • Carmencita Bright Red: It has red stems and bright red seed pods, along with dark purplish or bronzy-red leaves. This well-branched cultivar grows about 5-6 feet tall.

  • Carmencita Rose: It has blue-green foliage and peach-colored seed pods.
  • Gibsonii: It has dark red-tinged leaves and pinkish seed pods; it grows 4-5 feet tall.
  • Impala: It is a more compact cultivar that grows to 4 feet tall with reddish-purple leaves and stems, with the brightest color on the new growth.
  • New Zealand purple: It has smaller, reddish purple leaves and branches less than other types.
  • Red Spire: It grows 7-10 feet tall, with red stems, bronze leaves, and red seed pods.
  • Sanguineus: It has blood-red stems and leaves.
  • Zanzibarensis: It is another tall variety (7-10 feet) with green leaves with white midribs.

Health benefits of Castor beans

Castor seeds are well-known for several health properties and chief among them is the use of castor seed oil as a cleansing laxative and purgative.  Many herbalists make the use of castor bean oil in order to treat food poisoning. In Chinese medicine castor bean seeds also popularly known as castor oil seeds are used to extract the castor oil and use it as an external application. Listed below are few of the health benefits of castor beans

1. Rheumatism

Poultice prepared from castor seeds can be applied with beneficial results to gouty and rheumatic swellings. Decoction of the roots of castor plant with carbonate of potash is also useful in the treatment of lumbago, rheumatism and sciatica. Paste of the kernel without the embryo, boiled in milk, is also given as a medicine in these conditions.

2. Skin Disorders

Poultice of castor leaves is beneficial as an external application to boils and swellings. Coated with some bland oil such as coconut oil and heated, the hot leaves can be applied over guinea-worm sores to extract the worms. A poultice of castor seeds is also applied to scrofulous sores and boils due to tuberculosis of lymph nodes.

3. Bowel cleansing

Early evidence has shown that a single dose of castor oil given by mouth may help cleanse the bowels. Some research recommends that castor oil is more effective at causing bowel movements than a high-fiber diet or milk of magnesia and cascara. There is disagreement about whether castor oil is better than a commercial kit composed of magnesium citrate oral solution, phenolphthalein, and bisacodyl.

4. Problem of Breast Milk Secretion

Castor oil massaged over the breast after child-birth increases the flow of milk, as it stimulates the mammary glands. Castor leaves can also be used to stimulate the breasts, for the same purpose.

5. Dandruff

If used regularly as hair oil, it helps the growth of the hair and cures dandruff.

6. Jaundice and liver related problems

Fresh leaves of castor plant have hepato-protective action i.e. it protects liver damage. In case of jaundice in initial stage, use fresh leaf of plant to cure it. For this take 4-5 gm. of leaves and grind them. Add this to boiling water and make decoction and drink twice a day. Or take 4-5 gm. of leaves and extract its juice, mix with water and drink twice a day.

7. Constipation

Castor oil can safely be used round the year. It simply passes out after completing its purgative action, making the patient feel a mild irritation in the anus at that time.

Administration of castor oil as a purgative is very simple. About 30 to 60 grams of pure odorless castor oil is given orally with 250 to 375 grams of lukewarm milk. It acts just after an hour. Those who find its use nauseating and unpalatable: can take it with ginger water or aqua anisi in place of milk. This greatly reduces its’ unpleasantness, while destroying mucous and promoting healthy appetite.

8. Natural Birth-Control

According to Ayurvedic and Unani treatises, if a woman chews one castor seed daily for a period of seven days after the menstruation she becomes sterile. This has been interpreted by many that castor seed is an herb for birth control and if the woman swallows one castor seed, after the menstrual cycle she will not conceive during that month. When pregnancy is preferred, the practice can be given up and conception follows after a year.

9. Repellent properties 

Taste of the castor oil is terrible so it has been used as a spray to repel moles. Similarly the odor of the castor plants is unpleasant; thus, they have been used as repellent when planted around the mole infested areas. Care should be taken that children and pets have no access to the poisonous seeds.
