What is Greater Celandine?

The herb greater celandine ( Chelidonium majus), a relative of the poppy, contains an orange-colored juice that has been used medicinally for thousands of years. It has been applied topically for eye and skin problems, and taken internally for bronchitis, jaundice, indigestion, cancer, and whooping cough.

Test-tube and animal studies provide weak evidence that greater celandine may both stimulate and relax the gall bladder. 1 2 In Europe, it is commonly believed that minor gall bladder problems are a cause of indigestion. On this basis, celandine was approved in 1985 by Germany’s Commission E as a treatment for what we would call dyspepsia , or non-specific digestive distress.

Safety Issues

However, since it is not possible to determine in advance who would be at risk, we recommend that until more is known the internal use of greater celandine should be avoided entirely.
