Frequently Asked Questions

Does dong quai work for menopause symptoms?

As a standalone supplement, the evidence is not favorable. The Hirata et al. (1997) RCT found no benefit over placebo for menopausal hot flashes. However, this contradicts how dong quai is traditionally used in Chinese medicine, where it is always combined with other herbs in formulas tailored to the individual. If you are interested in dong quai for menopause, consider consulting a licensed TCM practitioner for a multi-herb approach.

Is dong quai a phytoestrogen?

This is debated. Early in vitro studies suggested weak estrogenic activity, but the Hirata et al. (1997) clinical study found no changes in estrogen levels, endometrial thickness, or vaginal cell maturation. Current consensus is that dong quai does not have clinically significant estrogenic activity when used at standard doses. Its traditional effects on menstrual health are more likely mediated through anti-inflammatory, antispasmodic, and blood-flow mechanisms.

Can I take dong quai with blood thinners?

No. Dong quai contains coumarins and has demonstrated anti-platelet activity. Combining it with blood thinners like warfarin, heparin, or even aspirin can significantly increase bleeding risk. Case reports have documented elevated INR values in patients taking warfarin with dong quai. Always disclose dong quai use to your doctor, and discontinue it 2 weeks before any surgical procedure.
