The castor plant (Ricinus communis) is easy to recognize thanks to its large, star-shaped leaves and striking appearance. While it has long been used in traditional practices, it’s also a plant that should be handled with care.

Here’s what you should know before using or growing it.

 

Are Castor Leaves Safe?

Castor plants contain naturally occurring toxic compounds, especially in the seeds. Because of this, no part of the raw plant should be eaten.

Some traditional remedies have used the leaves externally, but there is limited scientific evidence supporting these uses, and the leaves or sap may cause skin irritation in some people.

 

Castor Oil Is Different

Commercial cold-pressed castor oil is made through a controlled manufacturing process and is different from the raw plant. Always purchase castor oil from a reputable manufacturer and follow the product’s directions for use.

Never attempt to make castor oil from castor seeds at home.

 

Three Important Safety Tips

• Do not eat the leaves, seeds, or any raw part of the plant.
• Wear gardening gloves when pruning or handling castor plants, as the sap may irritate the skin.
• Keep the plant away from children and pets, especially the seeds, which are highly toxic if swallowed.
