Dong Quai (English name: Angelica sinensis) has been used in traditional Chinese medicine and Native American medicine for centuries. The plant is related to both parsley and celery and is most commonly used to treat cramps and pain during menstruation as well as to ease some of the symptoms of menopause (night sweats). Dong quai is frequently referred to as "female ginseng" to suggest its "balancing" or adaptogenic effect on the menstrual period. 

Angelica sinensis is a good remedy for colds, coughs, pleurisy, wind, colic, rheumatism and diseases of the urinary organs, and it is generally used as a stimulating expectorant, combined with other expectorants the action of which is facilitated, and to a large extent diffused, through the whole of the pulmonary region. It is also a useful agent for feverish conditions, acting as a diaphoretic.
