Castor oil plant - a plant that adorns the gardens of bold gardeners, as well as gardeners who love beauty, but do not know about the properties of castor oil plants. The plant practically does not require care, and diseases and pests bypass it - just plant the seedlings in the most honorable place of the garden and observe the growth of the northern palm.
Castor oil plant has been popular since ancient times - the plant is mentioned in ancient Greek and Roman literature, and castor oil seeds were found in the tombs of the pharaohs. Even the Bible did not forget to mention castor oil.
Castor oil plant is a really dangerous decoration for the garden. The fact is that all parts of the plant contain ricin, and castor seeds are the most toxic. Euphorbia are generally poisonous, but castor oil is simply a champion among euphorbia in toxicity. There is no sensible antidote for ricin, and the signs of poisoning are similar to a common cold. When all organs begin to fail, then doctors usually shrug. Many literary works describe the process of ricin poisoning - ground castor bean seeds. It’s enough to watch the final seasons of the series “Breaking Bad” to make sure that ricin is not a joke. And castor oil is your personal ricin in the garden.

By the way, castor oil is made from castor oil seeds.
If you have the courage and small children do not run around your garden, then it is worth growing castor oil, observing safety measures: rubber gloves for all agricultural activities, working on the leeward side, thorough washing of hands and face after the maintenance of castor oil.
Castor oil plant (Ricinus communis)
Description: Homeland - Africa. A monotypic genus having many garden forms and varieties.
From the history: as a cultivated plant, castor oil plant (Ricinus communis L) from the family of euphorbia was known in ancient times: its seeds were found in the tombs of Egyptian pharaohs, buried in the IV-III centuries BC. e. In the 1st century AD e. Roman encyclopedist Pliny described this plant and its properties. The Romans called it “castor”, which means “tick”: the seeds are like him. Hence the generic name of castor oil. According to the testimony of Herodotus and Diodorus, the ancient Greek name of castor bean came to Hellas from Ancient Egypt. The fact that the homeland of castor bean is regions of North and East Africa is recognized by most botanists. Thickets of perennial wild plants have been preserved on the entire northern coast of Africa to the present. From here, the castor bean tree settled inland along the major rivers of the Niger and Senegal. Very tall (up to 10 m) and powerful reddish plants are found in Ethiopia and along the coast of the Indian Ocean. Local residents have long planted castor oil, fencing it with thickets of dwellings and crops. They rubbed the body with oil from the seeds, this gave the skin freshness and shine, and in the cool time it protected it from the cold. Oil was also used to make hides and skins, to illuminate homes and even to fry vegetables, which was not done anywhere on other continents. From Africa, cultivated castor oil plants spread to Asia, and especially to India. The inscription made in Sanskrit in the I century BC. e „mentions the cultivation of castor oil and the receipt of oil from it for the refueling of lamps and from preparations and medicines. Nowadays, India holds the first place in the world in the production and export of castor oil seed.
Having arrived with the first colonists in Latin America, castor beetle quickly went wild there and settled on its own near human habitation, along roads and trails, and planting of cultivated plants became clogged.
In Europe, interest in castor oil appeared only at the end of the 18th century, after the British brought seeds to London from their southern colonies. The rapid development of technology in the 19th century and aviation at the beginning of the 20th century led to a sharp increase in demand for castor oil. Non-drying and non-freezing technical oil, a product of hot pressing of seeds (content of 40-58%), turned out to be an indispensable lubricant for the rubbing parts of machine tools, machines, and later aircraft. It has found wide application in textile, leather, paint and varnish, soap and perfumery production. Everyone knows castor oil, used in medicine as a laxative. It is obtained by cold pressing of seeds, as a result of which the toxic substances ricin and ricinin containing cyanides pass into cake and do not have a toxic effect on the body.
Russia became acquainted with castor oil in the first half of the 19th century, when one of the southern landowners, who served in the Russian embassy under the Persian Shah, brought seeds of this plant from India. Kishchevina quickly mastered not only in the Volga gardens from Astrakhan to Saratov, but also, running wild, went far into the steppe. In the middle of the century, the first attempts were made to grow plants in culture and to obtain oil from seeds. At that time, castor oil got several local names: “Turkish hemp”, “castor”, “paradise tree”. In Georgia, Abusalatini - so it was called here - was grown in gardens. In the Caspian lowland in the vicinity of Kizlyar, castor oil seeds were used to obtain oil for lamps and for medical purposes. In Turkmenistan, even before the Russians arrived there, castor oil was bred as a medicinal plant. The Turkmen called it “chakcha” (rattle), the Uzbeks called “kana” and “kanakunzhut” (kana - a tick, sesame - an oil plant). At the end of the 19th century, whole plantations of castor oil plants appeared on the Russian territories of Turkestan, Transcaucasia and in the Kuban-Black Sea district.
Subsequently, under the influence of cultivation and prolonged selection, races and varieties suitable for cultivation in a temperate climate arose. Today, castor oil is grown as an ornamental plant far beyond its original range, reaching Scotland, i.e., up to 56 ° north latitude. Naturally, in such a vast expanse both in culture (field and garden), and in the weed-wild state, African castor bean trees have greatly changed. This created great difficulties in compiling the taxonomy of the genus Ricinus, to which botanists attributed from one to 30 species for 200 years.

A perennial plant grown as a deciduous, annual. The bushes are relatively wide, sprawling, up to 200 cm tall. The stems are erect, branched, bare, green, red, brown with a bluish bloom. The leaves are arranged in the following order, large, green, on long hollow petioles, palmately separate, with 5-10 lobes. Flowers are nondescript, have no decorative value; they are collected in racemose, rather dense inflorescences. The fruit is an oval-spherical box covered with spikes, up to 3 cm in diameter. In 1 g from 8 to 25 seeds.
In the practice of floriculture, decorative forms with colored foliage and undersized varieties are more often used. For instance:
The most common domestic variety 'Cossack' - a powerful branchy plant up to 200 cm tall. The stems are brown-red, dark, shiny. The leaves are dark green with red veins, young are reddish-purple with white dots on the edges of the cloves. The flowers are bright red with dark-colored stigmas. Boxes of bright red, purple or carmine color, which persists until the seeds fully ripen.
Location: grows better and more decorative in sunny, warm and humid places. It does not tolerate frost and prolonged cooling.
The soil: prefers sites with deeply cultivated, loose, nutritious soil, chernozem.
Care: the plant is very responsive to the introduction of nitrogen before the formation of inflorescences. The assimilation of this nutrient contributes to a sufficient supply of moisture during the period from flowering to seed formation. Due to the slow initial growth, castor oil is easily drowned out by weeds, but on clean soil, seedlings grow well even with a lack of water.
Reproduction: seeds that are sown in March in pots or in April-May directly into the ground, 2-3 seeds per well. In seedlings, it is recommended to remove from the cotyledonary leaves the oily peel adhering to them, which causes the seedlings to rot. To get good seedlings, it is recommended to take pots of at least 20 cm in diameter. The day before sowing, the seeds should be soaked. It is recommended to sow castor oil to a depth of 6 to 1-2 cm at a soil temperature of at least 12 ° C. Shoots appear within 3 weeks.
The development of castor bean is unusually fast. If necessary, tranship the plants into large pots and arrange overgrown plants. With the right culture, in a short time, plants reach large sizes, with large leaves (up to 70-80 cm wide and up to 2 m or more in length). Plants are planted in the ground with the preservation of an earthen coma, in nutritious loose soil heated from manure. Seedlings are planted in a permanent place after the end of spring frost.
On industrial crops of stunted forms, the distance between rows is 60-90 cm and between plants in rows 20-30 cm. When decoratively using tall forms, the distance between them is 1 to 3 m so that the beauty of the plants is more visible.
Castor oil obtained from castor oil seeds has long been used in medicine as a laxative for enterocolitis, acute constipation of various etiologies, proctitis, inflammation of the gastrointestinal tract, poisoning (with the exception of poisoning with fat-soluble substances), food toxic infections, inflammatory conditions of the digestive tract, as well as for cleansing the intestines (thin and thick sections) before diagnostic procedures of internal organs. Castor oil is also used in eye practice with squamous blepharitis. In gynecology, castor oil is used for diseases of the vagina and cervix, and in obstetric practice it is prescribed to stimulate labor activity along with hormonal drugs (quinine, pachycarpine, etc.). External castor oil as part of liniment (Camphocin), ointments (Vishnevsky ointment), which have antiseptic properties and the ability to accelerate tissue regeneration, is used to treat diaper rash, radiation injuries of the skin, burns, ulcers, cracks, soften the skin, as well as balms - like means for improving hair growth, with seborrhea and diffuse hair loss. Castor-seed paste is recommended for the treatment of ulcers, cutaneous leishmaniasis.
Castor oil seeds, in addition to oil, contain highly toxic protein compounds, therefore the use of drugs from them is contraindicated during pregnancy, bleeding in the intestines and uterus, acute and chronic glomerulonephritis, poisoning with fat-soluble compounds (phenol, benzene, carbon tetrachloride and others) and male fern extract .
Side effects of poisoning with castor seeds: diarrhea, nausea, vomiting, headache, fever, abdominal pain, constipation after bowel movements is possible. With repeated use of drugs, addiction, digestion, enterocolitis, leukocytosis, impaired heart function, anuria, often cramps are possible, and even severe death can occur with poisoning.
In other areas
In the perfumery industry, castor oil is used to make high-quality soaps, hair cosmetics (balm - Hummingbird), creams (Special, Paprine), lotion (Resol), shampoos, eyeshadows, mascaras, lipsticks, nail polish removers .
Castor oil also has a technical purpose, it is used to lubricate machines, especially aircraft engines, since it has a high viscosity, does not dry out and does not freeze. In addition, castor oil is widely used in metallurgy, leather, textile and soap industries, in the manufacture of linoleum and many other synthetic products. Oil is also used as a fuel.
Castor oil plant is a wonderful ornamental plant; forms with variegated leaves are especially widely grown. Large, with beautiful marble colors castor seeds are used to make beads and other jewelry.
Castor oil bean plant (lat. Ricinus communis) - a species of the castor bean plant (lat. Ricinus) of the family euphorbiaceae (lat. Euphorbiaceae). The genus castor bean - monotypic, contains a single species - castor bean.
The generic name "Ricinus" comes from the Latin word "risinos" - a tick, the species "communis" - ordinary.
Monoecious plant. In culture, an annual herbaceous plant, reaching 2 m in height, dies very quickly from autumn frosts. In tropical and subtropical countries - a perennial plant with a tree-like stem up to 10 m in height. Lives up to 10 years. The root is powerful, pivotal, highly branched. The stem is hollow, articulated, branched, light green, or pink, red, purple or almost black. In some forms, the stem is waxy. Leaves with early falling stipules, alternate, two lower opposite, large, on long petioles (20-60 cm), glabrous, thyroid up to 80 cm wide, palmately dissected from 5-11 ovate-oblong dentate lobes. Flowers are nondescript, same-sex (male and female). Perianth simple, cup-shaped, three-five-separate. The stamens are numerous (more than 1000), in the upper part they are repeatedly branched. Pestle with an upper spherical-oval three-nested ovary. Inflorescences are brushes that are located at the ends of stems and lateral branches, as well as in the axils of the leaves. Male flowers are located in the lower part of the inflorescence, female flowers in the upper. The formula of the castor oil flower ordinary: ♂ * О0-5Т1-∞П0, ♀ * О0-5Т0П (3).
Fruit - a box, bare or covered with spikes, spherical or elongated, 1-3.5 cm in diameter, revealing with three wings. In the unripe state, the fruits of green, yellow, pink, red or purple, when ripening, turns brown. Seeds - large, up to 2.2 cm in length, ovoid or round-elliptical, with a marble-shiny mottled seed skin (sperm). Each fruit contains 3 seeds. It blooms in July - August, the fruits ripen in September.
The homeland of wild castor bean plant - tropical Africa and Asia, grows in Ethiopia. It is widely cultivated in all areas of the temperate zone of the globe as an annual culture. In Russia, it is cultivated mainly in the south of the European part - the North Caucasus, Krasnodar and Stavropol Territories, the Rostov Region and the Lower Volga Region.
Castor oil seeds contain up to 60% fatty oil (castor oil), consisting mainly of glyceride of unsaturated ricinolic (ricinoleic) acid, the content of which reaches up to 80-85%. The oil also contains stearic, oleic, linoleic, dioxistearic acid and glycerin. In addition to oil, seeds contain protein substances (14-17%), including toxalbumin, alkaloids (0.1-1.0%), nitrogen-free substances (10-12%), fiber (18-19%), and also extremely a poisonous substance of a protein nature - ricin. Pyridine alkaloid, ricinin, was found in all organs of castor bean.Ricinin belongs to the group of alkaloids with a rare combination of substituents, the presence of a cyano group is especially characteristic in it. This alkaloid is called "one of the most powerful known toxins." This substance, obtained from castor beans (also called castor bean fruit), is many times more toxic than potassium cyanide, sarin gas and cobra venom. Potassium, calcium, magnesium, iron were found from macronutrients in castor oil, manganese, copper, zinc, chromium nickel, molybdenum, lead, selenium, and beryllium were found from microelements.
Castor oil has a laxative and cleansing effect. When it enters the duodenum, oil under the influence of pancreatic juice lipase breaks down with the formation of glycerol and ricinolic acid, which are capable of irritating the receptors of the intestinal mucosa and, as a result, cause reflex enhancement of peristalsis of the small intestines, and then the large ones.
Under the influence of castor oil, the volume of intestinal contents increases, intestinal motility increases, and its emptying accelerates. The oil remaining in the intestine facilitates the movement of feces through the colon. The laxative effect develops 2-6 hours after taking the oil and weakens after bowel movement.
Castor oil also causes a reflex contraction of the uterus (myometrium).
Pregnancy and lactation. The use of castor oil is contraindicated during pregnancy due to the possibility of its early termination. Use in the III trimester of pregnancy is possible only for health reasons. If necessary, use during lactation should stop breastfeeding for the entire duration of treatment.
Use in pediatrics. The use of castor oil in children under 12 years of age is not recommended due to the high sensitivity of the intestines of children to irritating substances and the risk of dehydration.
Influence on the ability to drive vehicles and control mechanisms. While taking castor oil, it is not recommended to drive a motor vehicle, you should refrain from other operator activities in connection with a possible violation of the concentration of attention during the onset of the effect.
Caution when using. It is not recommended to use castor oil as a laxative for more than 3 days, because digestion, as well as the absorption of vitamins A and D, with the development of appropriate hypovitaminosis can be impaired. The use of castor oil in the treatment with medicines obtained from male fern is unacceptable, because however, their systemic absorption and the development of a neurotoxic effect are possible.
Interaction with other drugs:
With simultaneous use, it reduces the absorption of fat-soluble vitamins A, D and K. At doses up to 4 g / day, it increases the absorption of fat-soluble drugs - extract of male fern, mebendazole, griseofulvin, probucol.
With simultaneous use with salt laxatives, a sharp increase in the laxative effect is possible.
M-anticholinergics (atropine sulfate, platifilin, pirenzepine), antispasmodics (papaverine, drotaverin) weaken the effect of castor oil.
Anticholinesterase agents (neostigmine, pyridostigmine, rivastigmine) and glycerin enhance the laxative effect of castor oil.
It enhances the effect of agents that stimulate the contractile activity of the myometrium (methylergometrine, ergometrine, oxytocin, prostaglandins) up to the risk of uterine rupture in childbirth.
When applied topically, it increases the percutaneous absorption of drugs applied together with it on the skin.
- acute inflammatory bowel disease (including appendicitis),
- mechanical intestinal obstruction,
- abdominal pain of unknown origin,
- intestinal and uterine bleeding,
- acute and chronic glomerulonephritis,
- poisoning with fat-soluble poisons (including gasoline, carbon tetrachloride, extract of male fern),
- children's age (up to 12 years).
Application in traditional medicine
In folk medicine, castor oil is used as a laxative, strong anthelmintic and diuretic, as well as in ointments for the treatment of burns, ulcers, skin softening and for rubbing into the skin as a means of improving hair growth. Castor oil is used in home cosmetics to care for dry skin and hair. Folk medicine recommends castor oil to strengthen hair, with loss and baldness, against dandruff, and also to strengthen nails, eyebrows and eyelashes. Bulgarian cosmetologists use castor oil mixed with essential oil plants to treat nesting baldness.

Features of castor oil
Castor oil plant ordinary is a decorative leafy annual. This spreading plant can reach a height of 2-10 meters. Upright bare branched shoots can be painted in red, brown or greenish blue. Next-placed leaf plates with hollow long petioles look very impressive. Large palm-separated leaf plates in their composition include from 5 to 7 blades, while they are painted green. Thanks to its large spectacular foliage, the plant has become so popular among gardeners. But the dim flowers, collected in inflorescences in the form of a brush, have no decorative value. Fruits are boxes, on the surface of which thorns are located, they have an oval-spherical shape, and make the bush even more beautiful, located between the leaves. These fruits contain oval seeds that have a motley mosaic color: brown, pink, light pink against the background of the main color shade, which depends on the variety and may be brown-red, gray or otherwise. This plant is poisonous because it contains ricin pyridine alkaloid. Often cultivated low-grade varieties of castor oil plant with foliage, which has a bright color, for example, castor bean Zanzibar, a variety of Gibson or castor bean Cambodian.
Growing castor oil from seeds
Castor oil can be propagated only by seeds, and before seeding, they need to be scarified. According to statistics, out of 10 seeds sown, only 6 or 7 are germinated. To increase the percentage of germination and scarification is done, for this you just need to rub the seeds on an emery cloth and then immerse them in a solution of a growth stimulator for 12 hours (Heteroauxin, Epin, etc.). ) Sowing seeds can be done directly in the open ground in the last April days or in May. However, it is preferable to grow castor oil plant through seedlings, while sowing seeds is carried out in March or the first April days. For planting, it is recommended to use plastic buckets with a volume of 1 liter, which ½ part must be filled with garden soil. The seeds are sown individually, deepening only 20-30 mm. In the event that the seeds have been scarified, the first seedlings will appear after three or four days. If the sticky peel, which is located on the surface of the cotyledonary leaves, does not separate itself, it needs to be helped by using tweezers for this. Otherwise, rot may develop on the seed.
The seedling that has appeared is growing very actively. At first, the shoot is stretched, then the first leaf plate is formed, and it was at this time that the seedlings needed to be rearranged in a cool, well-lit place, while it should be noted that the temperature there should not drop below 15 degrees. As the flower grows, you need to gradually add soil to the container and do this until it is full. In the event that the growth of the plant is very fast, then it will have to be transferred to a larger pot. By the time it comes time to transplant seedlings into the open ground, it can have a height of about 100 centimeters.
What time to land
Castor oil plant differs in that it is completely capricious and undemanding to growing conditions. If you want it to grow very quickly and have an incredibly spectacular appearance, then for planting you should choose a warm, well-lit place with loose moist soil, saturated with nutrients. Plants feel best on chernozem. It will be possible to plant seedlings in open soil only after return frosts have passed, and this time, as a rule, falls on the last days of May or the first days - June.
How to plant
Before proceeding to planting, seedlings must be abundantly watered. Then the bushes, together with a lump of earth, are carefully transferred into the prepared pits, which are covered with simple garden soil and compacted well. After this, castor oil must be properly watered.
Sowing of castor oil plants directly into the ground is carried out in the first May days, while it is necessary to make not very deep holes and put in them 2 or 3 seeds.
Attention! The seeds of this plant are characterized by a high content of toxic substances. So, the lethal dose for a child is 6 seeds, and for an adult - 20 seeds. While working with castor oil, experts advise wearing gloves.
Castor Oil Care
Castor oil planted in open ground grows very quickly, and at the same time, no special efforts are required from the gardener. The main thing is to remember that such a flower needs systematic watering. So, every 5 days under a bush you need to pour a bucket of water. Weeding is needed only for young plants, and when they grow up, then weed grass will not interfere with them. Before the inflorescences begin to form, it is recommended to feed the plant with nitrogen-containing fertilizer.
Diseases and pests
Such a plant is highly resistant to harmful insects and diseases. If you planted the seeds directly in the open soil, then young plants can damage the false stalks, wireworms, caterpillars of the meadow moth, winter scoops, and a sand lark can also settle on them. During flowering, young fruits can damage meadow bugs. Get rid of the tracks is not difficult. In the event that there are few caterpillars, then they can be removed by hand, if there are a lot of them, then an infusion of wormwood will come to the rescue. In order to make it, you need to fill the bucket 1/3 part with chopped wormwood, and then pour so much water into it to make it full. The infusion will be ready in three days, it needs to be filtered and you can start processing the bushes. In the event that next to these flowers sow spicy greens (for example: dill, coriander, garlic, parsley, mint or onions), then the caterpillars will bypass them. It is very difficult to get rid of wireworm and rosemary, so it is better to resort to preventive measures before the plant becomes infected. For this, during planting, each hole should be shed with a not very strong solution of potassium permanganate.
Castor bean can get sick with pink, gray or black rot, cercosporosis, late blight, bacteriosis, phyllosticosis, powdery mildew and other fungal diseases. It is recommended to treat infected bushes with Bordeaux liquid or other similar means.
In the event that you decide to collect seeds from plants grown by you, then in the summer, mark those bushes that look most impressive, are absolutely healthy and powerful. In the first days of September, the fruits must be cut and folded to dry in a room with good ventilation. Seed boxes dry only in November or December. If the fruits dry very well, then with light pressure they should completely crumble, and from them, seeds of 2 or 3 pieces will fall out, which are similar in appearance to beans. Remember that working with castor beans and its seeds must always be in gloves. These seeds must be stored in a place where children or animals cannot reach them. They remain viable for at least four years.
Castor bean Zanzibar
This fast-growing annual plant can reach a height of 200 centimeters. He has spectacular racemose inflorescences and large leafy plates. In single plantings, it looks like a rare tropical plant, in connection with this it is planted, as a rule, as a tapeworm. The leaf plates are painted purple-red.
Castor bean Borbon tree
The height of the bush can reach up to three meters. The dense trunk has a red color. Large green leaf plates are glossy.
Russian breeders managed to develop a decorative variety, which became very popular, and it is called Cossack. The bush reaches 200 centimeters in height, it has a glossy brownish-red trunk, as well as dark green adult leafy plates with reddish veins. Young leaves are colored purple-red and have white dots along the edges of the teeth. Red-bloody flowers have stigmas of a darker shade. Fruits can be purple, red or carmine.
Benefits and harms of castor oil
Despite the fact that castor oil is poisonous and contains a large amount of ricin venom, it is very useful for humans, because valuable essential oil is extracted from it. Castor oil plants are even grown on an industrial scale to produce this oil. The composition of this oil contains unsaturated glyceride, oleic, stearic, linoleic acid and glycerin, as well as micro and macro elements magnesium, iron, calcium and potassium. Castor oil (castor oil) made on the basis of oil extracted from castor oil seeds is used as a laxative in the treatment of enteritis, constipation, colitis and other intestinal diseases associated with inflammation. It is also used externally for bruises, wounds, burns, ulcers, warts and colds. This oil is used in the treatment of varicose veins and hemorrhoids. And it is used as drops for eye inflammation and in the treatment of gynecological diseases. You can buy such oil in capsules or in small bottles of dark glass. When stored in a refrigerator, it can retain its useful properties for up to several years, while the oil should be in a bottle of dark-colored glass, which has a tightly ground stopper.
Such a plant is also used in the treatment of endometriosis. To do this, you need to take 10 grams of fresh leaves, cut them finely and combine with 200 ml of freshly boiled water. Boil the resulting mixture for 15 to 20 minutes. over a small fire. Then the mixture will need to be infused for several hours, after which it should be filtered. Drink the infusion of 1 large spoon three times in knocking for 14 days.
To treat bronchitis or colds, a tepid castor is used. It should be rubbed several times in knocks into the patient’s chest area, after which the person is well wrapped. Every day, castor should be rubbed into problem areas with warts, burns, wounds, hemorrhoids or varicose veins. In case of eye inflammation, 1 or 2 drops of castor oil should be dripped in the eyes before bedtime for 3-5 days.
Castor has also found wide application in cosmetology. It is used to treat the skin surface of the head and hair, to remove age spots, to get rid of wrinkles and other irregularities of the epidermis. And with the help of such oil they fight with corns and corns.
Several popular recipes
- Eyelash strengthening. Dip the brush into the castor and spread it over the cilia, while keeping the product out of the eyes. 30 minutes later remove unabsorbed oil from the eyelashes with a napkin. To obtain a visible result, it is necessary to carry out such procedures every day for a month.
- Problem skin. Steam the skin surface of the face and spread a warm castor on it. After 60–90 minutes Wipe your face with a paper towel and rinse it with cool water.
- Hair loss. In a small container, combine freshly squeezed lemon juice, castor oil and alcohol taken in a 1: 1: 1 ratio. This composition before bedtime should be rubbed into the skin surface of the head. In the morning, it needs to be washed off with a large amount of tepid water.
- Dandruff. Combine the castor and tincture of calendula in a 1: 1 ratio. Then the mixture must be rubbed into the skin surface of the head. 30 minutes later need to wash your hair.
The funds made of castor oil have contraindications. They can not be used by pregnant and breastfeeding women, with exacerbation of chronic diseases (even chronic constipation), with intestinal and uterine bleeding, with individual intolerance, with intestinal obstruction of a mechanical nature. Experts do not recommend the use of such drugs to treat children under 12 years old.
Castor oil in the garden: features of growing
Like other heat-loving decorative plants, castor bean plants are grown in seedlings - planting seeds in open ground threatens to damage the young plants with return frosts. In the southern regions, you can plant seeds directly in the open ground, one seed per hole.

Castor bean seeds for seedlings are sown in separate cups or peat pots in March, observing safety precautions. When the threat of frost has passed, seedlings are planted in a permanent place in the garden.
Before planting, seeds must be soaked in water for a day. Depth of planting of castor bean seeds - Castor bean seedlings appear through . When seedlings of castor oil appear, it is necessary to remove the oily peel from the cotyledonous leaves so that the seedlings do not rot.
You can’t call castor seedlings frail - the height of the sprouts immediately after germination reaches 5 cm. If there is a need, castor bean plants are thinned, observing a distance of 5 cm between adjacent plants.
Castor bean seedlings grow rapidly, so immediately after the appearance of these leaves, seedlings growing in a common container are dived into separate containers. Seedlings are planted in a permanent place after the end of spring frost. An earthen lump on seedlings must be preserved to reduce the survival time of the plant.

Castor Oil Care simple: plentiful watering, weeding and top dressing with nitrogen mineral fertilizers. If the soil is rich in nutrients, then you can do without fertilizing at all.
Designers advise planting castor oil at a distance so that the beauty of castor oil does not turn into a uniform wall. The distance helps to fully reveal the beauty of the northern palm. The plant looks good against the background of low walls - on a sunny day, large castor leaves give an openwork shadow to nearby objects.
Varieties of castor oil
Due to the prevalence of castor oil, ordinary castor oil was transformed into several varieties, which differ in the structure and color of the leaves and trunk. During mutations, the plant has not lost its toxicity, therefore, when growing all types of castor oil, accuracy is required.
Meet the types of castor oil:
- Castor oil plant has a green stem that reaches a height of 120 cm, the leaves are large glossy.
- Bourbon castor, tree-like grows up to 3 meters up. The plant has a red trunk and large shiny leaves.
- Castor bean Zanzibar reaches a height of 2 m. The plant is famous for its dark red leaves of gigantic size.
- Castor oil plant Indian grows to a height of 120 cm: the leaves are dark green, the trunk is black.
- Gibson Castor Oil grow to 150 cm in height, leaves and trunk of the plant are dark red.
Castor oil (castor oil seed oil) is used in scientific medicine:
- Castor is prescribed for inflammation of the gastrointestinal tract, colitis and fever.
- Outwardly, castor oil is used to treat ulcers, burns, and also when removing warts.
- In cosmetology, castor oil is used for whitening age spots and rapid eyelash growth.
- In gynecology, castor oil is used to stimulate labor.
- Infusion of castor bean grass treats inflammatory diseases of the uterus, and with colds and bronchitis they rub the chest.
Infusion of castor leaves: 10 grams of chopped leaves should be poured into a glass of boiling water and insisted for 15 minutes in a boiling water bath, then cool and strain the infusion. It is recommended to take the infusion 3 times a day for 1 tablespoon with endometritis.
