Are castor bean plants safe to touch?
Castor Bean is an exotic ornamental, semi-woody, fast-growing, large shrub or small tree that is extremely toxic to humans. It can be fatal if only a few seeds are ingested and also causes contact dermatitis when the foliage is handled. It is an herbaceous perennial in winter hardy zones 9 to 11. Several cultures used it as a purgative. Today it is used as a high-grade industrial oil and as a component in products as varied as paints and varnishes, soaps, inks, plastics, perfumes and skin creams. In 2013, world-wide commercial production of castor bean seed was estimated to be nearly 2 million tons.Since the toxin does not occur in the pure oil, castor oil can be consumed and has been used medicinally as a remedy for everything from constipation to heartburn. It is an effective cathartic or purgative (laxative) and can be used externally as an emollient for dry skin. Castor bean is often grown as an ornamental.In the United States, castor bean plants were grown to produce castor oil, which was used in making soaps, linoleum, nylon, paints and electrical insulations.

Watering: Keep the soil moist but not soggy. Water deeply and ensure proper drainage. Soil: Use well-draining, nutrient-rich soil.
What if someone eats castor beans?
Castor beans contain ricin, one of the most toxic substances known. They may cause an acute and potentially fatal gastroenteritis. Delayed visceral damage is another serious complication; however, the latter is quite rare. The toxicity is dose related and depends on the amount of castor beans ingested. If you think you’ve been exposed to ricin, get into fresh air and call 911 or your local emergency number right away. Ricin is a poison that can be made from the waste left when castor beans are made into castor oil.This plant is deadly poisonous. The castor bean contains a highly poisonous substance known as ricin that when inhaled or ingested can be lethal to humans and animals. Handling the foliage may cause severe contact dermatitis. Wear gloves and other protective equipment to avoid allergic skin reactions.Is ricin poisoning survivable? Yes, ricin poisoning is survivable. With proper care, about 98% of people who ingest ricin survive. There’s very little data about survival from inhaling or injection because it’s so rare for these to happen.If ricin is eaten, it can cause vomiting and diarrhea. It can cause bleeding in the gut and organ damage. The poison can kill a person within three days. Even a small amount of ricin can kill.The seed is only toxic if the outer shell is broken or chewed. Ricin is contained in the bean pulp following the separation of the oil from the beans. No ricin is thought to remain in the oil, and it is inactivated during extraction if done under heated conditions.
What plant toxin comes from the castor bean plant?
Ricin is a poison found naturally in castor beans. If castor beans are chewed and swallowed, the ricin that comes out can cause injury. Ricin can be made from the waste material left over from processing castor beans. Recommended treatment for asymptomatic patients who have chewed one or more raw beans is emergency department evaluation, gastric decontamination, administration of activated charcoal, observation until four to six hours after ingestion, and discharge instructions to return if symptoms develop.Clinical Signs: Beans are very toxic: oral irritation, burning of mouth and throat, increase in thirst, vomiting, diarrhea, kidney failure, convulsions.

Castor bean grows best in full sun and can reach heights of up to 40 feet where frost is not present.Legal Implications of Growing Castor Beans If you are found to be commercially producing castor beans, you can be charged with a misdemeanor and fined up to $500. The reason for this restriction is that castor beans contain ricin, a highly toxic substance.The seeds of the castor bean plant contain ricin, a toxic protein that, when properly processed, can yield castor oil. Castor oil has been used historically for a wide range of purposes, from medicinal applications to industrial uses. Its oil was an essential ingredient in lubricants, soaps, paints, and varnishes.
