Overview

Dong quai (Angelica sinensis) is a plant that has been used for a variety of conditions, with little evidence. It may be unsafe when too much is consumed.

Dong quai is a member of the same plant family as parsley, celery, and carrots. It's popular in Chinese medicine for female health concerns. The root might affect estrogen and other hormones.

People commonly use dong quai for menopausal symptoms, menstrual cramps, migraine, and many other conditions, but there is no good scientific evidence to support these uses.

Uses & Effectiveness ?

Possibly Effective for

  • Menopausal symptoms. Various combination products that contain dong quai seem to reduce menopausal symptoms. Taking a specific product containing dong quai and chamomile (Climex) seems to reduce hot flushes in menopausal women. Taking a specific product containing American ginseng, black cohosh, dong quai, milk thistle, red clover, and vitex agnus-castus (Phyto-Female complex) seems to reduce hot flushes and night sweats and improve sleep quality in pre- and post-menopausal women. Taking a product containing burdock root, licorice root, motherwort, dong quai, and Mexican wild yam root seems to reduce menopausal symptoms as well. However, some evidence suggests that taking dong quai alone does to improve symptoms of menopause.
  • Premature ejaculation, when applied directly to the skin of the penis in combination with other herbs. The other herbs are Panax ginseng root, Cistanches deserticola, Zanthoxyl species, Torlidis seed, clove flower, Asiasari root, cinnamon bark, and toad venom (SS Cream).
