For centuries, castor leaves — from the Ricinus communis plant — have been used in traditional medicine across Africa, the Caribbean, India, and parts of South America.
Known for their large, star-shaped leaves and medicinal seeds (source of castor oil), this plant has been used to:
- Soothe skin irritation
- Reduce inflammation
- Support wound healing
- Ease joint pain
But while castor leaves have a long history of use, they also come with serious risks — because every part of the plant contains ricin, one of the most toxic substances known.
Let’s explore the traditional uses of castor leaves, what science says, and why caution is essential — so you can make informed decisions about your health.
🌱 What Are Castor Leaves?
Castor leaves come from the castor bean plant (Ricinus communis), a fast-growing shrub found in tropical and subtropical regions.
- Large, palm-like leaves (up to 3 feet wide)
- Source of castor oil (extracted from seeds)
- Used in folk medicine, poultices, and topical treatments
⚠️ Important: The seeds are extremely poisonous due to ricin, a potent toxin. Leaves also contain lower levels of toxins and alkaloids.
✅ Traditional Uses of Castor Leaves (Topical Only)
In traditional healing practices, castor leaves are rarely eaten — they are most commonly used externally in the form of:
- Warm poultices
- Leaf wraps
- Infused oils or compresses
