Can You Eat Castor Beans
Castor seeds that have been hulled, or had their outer layer removed, may be safe to consume in one dosage. It is NOT SAFE to consume the entire castor seed. Ricine, a lethal toxin found in the castor seed’s hull, is present. Castor beans naturally contain the toxin ricin.
Castor beans, which are sometimes used in traditional therapies, contain one of the most toxic substances known, ricin. In the garden, the danger from castor beans is not posed particularly by handling the occasional castor bean, but by eating parts of the plant, namely leaves and, particularly, seeds, which contain the highest concentrations of ricin. Growing the plant as an ornamental or a crop is not illegal, but mining it for and concentrates the potent toxin ricin is, since in effect, one is making a potent biological weapon (of course, this is also something I would recommend against).

Interestingly, one source I checked indicates that humans will ingest the seeds of castor beans without incident, since our intestines will not digest and otherwise destroy the seeds coating, exposing the potent ricin toxin. The seeds contain a protein called ricin, and it is undisputed that ricin is highly toxic to humans, animals, and even insects. Ricin is a very toxic component which disrupts protein synthesis; eating just an ounce of seeds can kill.
Assuming appropriate medical treatment, victims of the toxicity usually recover from eating a single seed pod. However, some variability can occur in the severity of the poisoning symptoms, depending on individual reaction, quantity consumed, and if The seeds are ground up or eaten whole, with the former being far more toxic. Take steps to make sure children and pets do not come in contact with the seed pods, since they are toxic.
Remove them from plants and dispose of them in your home garbage bin instead of your compost bin. Since taller varieties of castor beans are known to become naturally established, a beekeeper may be able to prevent it by removing seed pods before they split open. The seeds are extremely toxic, so keep plants away from children (or cut the blossoming stalks if that is a concern).

The castor plant is a handsome, large, semi-woody shrub that can grow up to 40 feet high in the right conditions. Plants may need pruning to restrict the size, or they may require staking if they are top-heavy; otherwise, Castor beans require little to no maintenance. When grown as an ornamental, castor beans may be planted directly into a garden at the end of spring, or started indoors early (6-8 weeks before average last freeze) and moved outdoors when conditions warm. Castor beans are native to tropical eastern Africa around Ethiopia, but they have become a naturalized species in tropical and subtropical areas of the world, becoming a weed in many places, including in the Southwest United States. Plants are usually found in moist, well-drained soils in disturbed areas, such as along rivers beds and roadside, as well as in fallen fields or the edges of farmland.

The plant castor beans, Ricinus communis, is a tropical African species that is grown in many North American gardens because of the fantastically large leaves that the plant has. Originally originating from the south-east Mediterranean, East Africa, and India, castor beans are now found everywhere in the tropical region, having been grown as an ornamental and medicinal plant for centuries. It can be used to create a temporary screen or informal hedge, or grown in large containers on patios. Deadly ricin is a naturally occurring protein which is part of a leftover waste pulp created when beans from the castor plant (Ricinus communis) are processed for castingor oil.
The toxic properties of Deadly ricin were probably known from the time of its discovery, when its beans were eaten as food; only after German scientist Peter Hermann Stillmark extracted the toxins in 1888 did the use as a bioweapon become a possibility. Deadly ricins sensitivity to heat made its use in projectiles problematic, and it was rejected for creation until anti-toxin was found.
The plans likely would not have worked, as deadly ricin likely would not be absorbed through the skin. As injected ricin worked its way outward, it would cause internal bleeding, with death coming from multiple organ failures.
Death due to ricin poisoning probably would not have occurred had the victim lived longer than 5 days without complications. Death from ricin poisoning may occur between 36 to 72 hours after exposure, depending on the mode of exposure (inhalation, ingestion, or injection) and the dose received. The main symptoms of ricin poisoning depend on the route of exposure and dose received, although in severe cases, many organs can be affected.
Ricin poisoning is not easily detected, but is not necessarily deadly, although medical personnel are unlikely to be able to determine a primary cause. Symptomatic ricin poisoning is treated by providing the affected person with supportive health care to minimize the effects of poisoning.
The toxins found in the Castor seeds are ricin (RYE-sin), which is one of the deadliest of the natural poisons, estimated as being 6,000 times more toxic than cyanide and 12,000 times more toxic than rattlesnake poison. Because the toxins in castor seeds are not found in thick form, castor oil is edible, and has been used in medicine as a treatment for everything from constipation to heartburn. Castor oil is used as a laxative to help with constipation, for starting labour during pregnancy, and for starting breast milk. Castor oil is used externally for softening of the skin, bunions, and corns; and to loosen cysts, growths, and warts.
Of course, many people will recall the wide usage of castor oil as an all-purpose laxative in times gone by (though no milder). In the United States, castor oil, which is food-grade, is a recognized food safety ingredient, used in flavourings and candies, and for mold-inhibitors, and for packaging. Some studies have shown that a particular form of castor oil, extracted from beans, actually works against mowing down moles, voles, and other ground insect pests if applied to the soil.
Since castor beans (Ricinus communis) are not a native plant (but they have become naturalized in many places throughout the south), Mr. Smarty Plants cannot offer any advice about that. The VetLibrary webpage for Castor Beans says, All parts of the plant are toxic, but seeds are most dangerous. This is the main danger from poinsettias, the popular festive plants (and castor-bean cousins), though a small proportion also get allergic reactions from foliage (not quite as severe as with poison ivy).
Can you chew castor seed?
The entire seed is UNSAFE to take by mouth. The external covering (structure) of the castor seed contains a dangerous toxin. This external covering can cause sickness; regurgitating; looseness of the bowels; stomach torment; lack of hydration; shock; platelet obliteration; extreme liquid and substance aggravations; liver, kidney, and pancreas harm; and death.
Is having ricin illegal?
The FBI has charged individuals for endeavoring to get the poison, which became unlawful in July 2019. Ricin is an inconceivably perilous organic poison only a couple of little grains can kill a human, a 2019 delivery quotes U.S. Lawyer Nick Hanna when a California man conceded to endeavoring to purchase ricin.
What are Castor beans good for?
Castor oil can be consumed and has been used medicinally for everything from constipation to heartburn because the toxin does not occur in the pure oil. It has cathartic or purgative (laxative) properties and can be used externally as an emollient for dry skin. Castor bean is a popular ornamental plant.
