The laxative effect of the product helps cleanse the body when losing weight. To do this, you need to drink a teaspoon of oil orally in the morning or evening and abstain from food. You can drink after an hour. Depending on the dose, the effect of the drug occurs within six hours.
Another laxative is prepared from a mixture of castor oil and the juice of any citrus fruit: 1 milliliter of oil per kilogram of weight and 2 milliliters of juice per kilogram of weight. The maximum dose of castor oil per day is 100 milliliters, regardless of weight.

Top dangerous properties
Castor seed kernels are 17 percent protein. One of them, ricin, is a poisonous toxalbumin with a pronounced toxic effect.
Protein is also present in the fatty oil extracted from the seeds. The second name for castor oil is ricin. But after processing it loses its toxic properties. Also, the kernel of castor bean seeds contains up to 1 percent of the alkaloid ricinin.
Unlike fatty oil, castor bean leaves and stems are abundantly filled with toxic substances. Eating parts and seeds of the plant is dangerous to human and animal life.
The average lethal dose of ricin and ricinin is 500 micrograms. The substances are as lethal to humans as potassium cyanide and cobra venom. Symptoms of castor bean poisoning:
- vomit;
- colic and bleeding in the intestines;
- imbalance of electrolytes due to dehydration.
Just 10 castor bean seeds cause irreparable harm to the body. There is no antidote for ricin or ricinin. Death occurs seven days after poisoning. Even with timely medical care, castor bean toxins quickly penetrate the body's tissues and destroy proteins in cells, so the person will experience health problems for the rest of his life.
Application
In castor beans, the main source of raw materials for various industries is seeds. Castor oil is used in medicine, cosmetology and industry. To add it to preparations, it is obtained by cold pressing and treated with hot steam. This technology neutralizes the toxic effects of ricin and ricinin. Protein and alkaloid are destroyed by high temperature and hydrolysis.
Castor oil dissolves only in alcohol and thickens when exposed to oxygen. At temperatures below 15 degrees below zero, it does not harden, but hardens to the consistency of jelly.

Care instructions
Castor beans are grown only from seeds. You have to wait a long time for sprouts due to the hard shell. Therefore, the seeds must be prepared for germination - lightly rubbed with sandpaper and kept in warm water for a day. Then they are planted in plastic or clay pots to a depth of 2 centimeters. The seedlings are covered with plastic wrap and placed in a warm, sunny place.
Sprouts appear after three weeks. After a month they can be planted in the garden. A favorable time for planting seedlings or seeds in open ground is May.
The selected area is fertilized with humus and compost. An interval of about a meter is left between the holes for seeds or seedlings. Place 2-3 seeds in one hole. A well-lit and protected from the wind corner is suitable for castor beans.
The tropical plant does not like shade and cold. Young shoots do not survive spring frosts, so it is better to plant castor beans in late spring or early summer. How to care for the plant:
- pour 10 liters of water under each bush every week;
- when buds appear, apply fertilizers with potassium and phosphorus;
- tie young bushes to pegs;
- in the first months, carefully remove weeds; the grown castor oil plant itself will displace unwanted neighbors;
- loosen the soil regularly, as the roots need oxygen.
Castor beans rarely get sick with proper care. Sometimes wireworms, caterpillars or cotton bollworms appear in the bushes.Any insecticides or spraying with wormwood infusion will help control pests.
With high humidity and lack of light, a fungus appears on castor beans - powdery mildew, brown spot or late blight. In this case, the plant is treated with Bordeaux solution or fungicides.
