Don Quai

Don Quai is a herb native to eastern Asia and China. It has been used for more than one thousand years, as a spice, tonic and medicine in traditional Chinese medicine. Don Quai is known as the 'female ginseng' and is currently the second best selling herb in China. It is indicated for painful menses, irregular menstruation, and as a supportive herb for menopausal complaints. In the west, Don Quai has become popular as a herb for treating menopausal symptoms. However, the one well designed study that has been conducted using Don Quai has found no beneficial effects. Don Quai is one of the first alternative therapies to which potentially adverse effects have been attributed, as it potentiates the effects of the blood thinning drug, warfarin. Don Quai contains chemicals that act as blood thinning products.
