How Supplied:

Seven different coumarin derivatives have been identified in Dong Quai, including psoralen, oxypevledanin, osthole, imperotorin, and bergapten. Some of these have a central nervous system stimulant effect, and some act as vasodilators and anti spasmodics.

However, psoralen and berapten cause severe photosensitive dermatitis, and investigators have concluded that these ingredients cause sufficient risks to humans and should be avoided.

Substantial clinical evidence is lacking to support the effectiveness of Dong Quai for the various clinical conditions it is purported to alleviate, and consequently the use of this herb is not recommended .
