Rating (out of 5): 2

Dong quai (Angelica sinensis) has a long history in traditional Chinese medicine (TCM) as a remedy for women’s health issues, including menstrual irregularity. In TCM, it is often called the “female ginseng” and is believed to nourish the blood, regulate menstrual cycles, and alleviate symptoms such as cramping and pain. Dong quai is commonly used in herbal formulas like Dang Gui Bu Xue Tang and Si Wu Tang, which are prescribed for menstrual irregularities, amenorrhea (absence of menstruation), and dysmenorrhea (painful menstruation).

Scientific evidence supporting dong quai’s effectiveness for menstrual irregularity is limited and generally of low quality. Some laboratory and animal studies suggest that dong quai contains phytoestrogens and may have mild uterotonic effects, which could theoretically influence menstrual cycles. However, clinical trials in humans are few, small in scale, and often inconclusive or methodologically weak. Most reviews conclude that while dong quai is widely used traditionally for menstrual issues, there is insufficient robust clinical evidence to confirm its efficacy for this specific purpose.

In summary, dong quai’s use for menstrual irregularity is primarily justified by traditional use rather than strong scientific validation. Women interested in trying dong quai for menstrual irregularity should consult healthcare providers, especially due to potential interactions with medications and concerns for those with hormone-sensitive conditions.
