If you are considering using an herbal supplement, it is usual to question whether they actually work or not. There is often controversy surrounding the use of supplements because researchers seem to conduct fewer clinical trials or human testing on these supplements. The U.S. Food and Drug Administration, or FDA, does not evaluate herbal supplements, which often causes concern. Herbalists have used angelica sinensis for centuries to treat many gynecological problems and high blood pressure. If you are considering using dong quai, you should discuss the risks and benefits with your physician.
Dong Quai
Dong quai grows in high altitudes of the mountains of Korea, China and Japan. The perennial grows in cold, wet weather and is a member of the celery family. In Chinese medicine, herbalists most often use the yellowish-brown roots of dong quai in combination with other herbs to help strengthen the liver and spleen. Traditional Chinese practitioners believe that the herb returns the body to a proper state by nourishing blood and harmonizing energy, according to MayoClinic.com.
Uses
Many holistic practitioners use the root of dong quai to treat a number of conditions, such as headaches, inflammation, high blood pressure, pain relief, premature ejaculation and suppression of allergies. Dong quai may contain estrogen-like substances that react similarly in the body. The University of Maryland Medical Center explains that these substances purportedly help relieve hot flashes, night sweats, vaginal dryness and mood swings associated with menopausal symptoms by replacing the estrogen that decreases during menopause. Herbalists also use dong quai for relief of painful menstrual cramps, irregular menstrual cycles, premenstrual syndrome and infrequent periods.
Scientific Evidence
As of 2010, researchers have conducted very few clinical trials to assess the effectiveness of dong quai. The National Institutes of Health states that dong quai is possibly effective in the treatment of premature ejaculation when applied topically to the penis. They go on to state that dong quai is possibly ineffective for the treatment of menopausal symptoms. There is insufficient evidence to support claims that dong quai is beneficial for the treatment of high blood pressure, premenstrual syndrome, constipation, anemia, allergies, skin discoloration, psoriasis, ulcers, joint pain or painful menstruation.
Warnings
Dong quai contains substances that stimulate the uterus so you should not use the herb if you are pregnant as it may cause a miscarriage or induce pre-term labor. Dong quai may increase the effects of anticoagulant medications, such as aspirin, warfarin, heparin, lovenox and nonsteroidal anti-inflammatory medications, increasing the risk of bruising and bleeding. Dong quai may also interact with other herbal supplements that affect clotting of the blood including, garlic, gingko, ginger, feverfew, licorice, turmeric, Chinese skullcap and ginseng, increasing the risk of bleeding.
Considerations
Always discuss the use of dong quai with your physician before you take the supplement. The FDA does not regulate safety, effectiveness or purity and some herbs have contained other drugs and toxic metals. Always buy herbal supplements from a certified herbalist or holistic practitioner.
