| Description |
Ba Dou (巴豆), also known as Croton tiglium, is a medicinal herb commonly used in traditional Chinese medicine (TCM). It belongs to the Euphorbiaceae family and is native to Southeast Asia, including China, India, and Malaysia. Ba Dou seeds are known for their potent properties but also require careful handling due to their strong purgative effects and toxicity.
Characteristics
- Appearance: Ba Dou seeds are small, brown, and slightly oval, with a smooth, shiny exterior.
- Active Compounds: Contains croton oil, which has irritant properties, as well as compounds like phorbol esters that contribute to its medicinal effects.
Uses in Traditional Medicine
In TCM, Ba Dou is typically used to:
- Expel Cold: It’s often used in cases of severe cold accumulation in the body.
- Purge Phlegm: Known for its ability to eliminate phlegm from the respiratory tract.
- Relieve Constipation: Strongly stimulates bowel movements due to its purgative effect.
Preparation and Precautions
Because of its toxicity, Ba Dou is used only in very small doses and often processed to reduce harsh effects. Direct ingestion is typically avoided, and it's usually prescribed by a trained practitioner in specific forms or combined with other herbs to mitigate its intensity. It should not be used by individuals with weak constitutions, pregnant women, or those with gastrointestinal issues.
