Rating (out of 5): 2

Dong quai (Angelica sinensis) has been used in traditional Chinese medicine for centuries, particularly as a remedy for women's health issues, including dysmenorrhea (painful menstruation). It is sometimes referred to as “female ginseng” and is often included in herbal formulas aimed at harmonizing and nourishing the blood, regulating menstrual cycles, and relieving menstrual pain. The root is believed to have antispasmodic and anti-inflammatory effects, which might theoretically contribute to relief from uterine cramps and pain.

However, the scientific evidence supporting dong quai’s effectiveness for dysmenorrhea is limited and generally of low quality. Most clinical studies investigating dong quai for menstrual disorders are small, lack rigorous controls, or use dong quai as part of multi-herb formulations, making it difficult to assess the root’s specific effects. Some laboratory studies suggest that compounds in dong quai may relax uterine muscle and modulate prostaglandin production, which could reduce cramping, but these findings have not been consistently confirmed in human trials.

In summary, the use of dong quai for dysmenorrhea is primarily justified by traditional use, with only limited and weak evidence from scientific studies. More well-designed clinical trials are needed to determine its true efficacy and safety for this indication.
