  • Premature ejaculation: A multi-ingredient topical cream, containing Dong quai, is applied to the penis one hour prior to sex and washed off immediately before sex.
  • Menopausal symptoms: Take 4.5 grams of powder by mouth daily or 520 to 1560 mg by mouth three times daily with meals.
  • Liquid extract: Take 1 ml by mouth three times a day.

DRUG INTERACTIONS: Dong quai has blood thinning effects (slow blood clotting) and should not be taken with blood thinning medications like warfarin (Coumadin), aspirin, clopidogrel (Plavix), and pain medications like ibuprofen (Motrin), naproxen (Aleve, Naprosyn), and diclofenac (Voltaren). Such combinations increase the risk of bruising and bleeding. It should also not be combined with herbs that also slow blood clotting. Examples include angelica, clove, danshen, garlic, ginger, ginkgo, panax ginseng, poplar, red clover, and willow.
