Corydalis yanhusuo


Corydalis yanhusuo is flowering plant that grows in mild climates throughout the northern hemisphere. It's used in traditional Chinese Medicine (TCM).

The root and tuber of the Corydalis yanhusuo plant are used in medicine. They contain chemicals that might help fight certain infections in the stomach.

People use Corydalis yanhusuo for constipation, indigestion, acid reflux, headache, and many other conditions, but there is no good scientific evidence to support these uses.

Don't confuse Corydalis yanhusuo with other species that might be generally called Corydalis. These are not the same.
When taken by mouth: A specific combination product (Motilitone, Dong-A ST) containing Corydalis yanhusuo extract and Pharbitis seed extract is possibly safe when used for up to 4 weeks. But there isn't enough reliable information to know if taking Corydalis yanhusuo alone is safe or what the side effects might be.

Special Precautions & Warnings:

Pregnancy: Corydalis yanhusuo is likely unsafe when taken by mouth during pregnancy. It might start menstruation and cause the uterus to contract. This could cause a miscarriage.

Breast-feeding: There isn't enough reliable information to know if Corydalis yanhusuo is safe to use when breast-feeding. Stay on the safe side and avoid use.
