The evidence in words

What it is

Dong quai (Angelica sinensis) is a Chinese herb used for menstrual and menopausal symptoms.

How it works

Contains coumarins and phytochemicals with proposed (but unclear) hormonal and vascular effects.

What the evidence shows

Controlled trials, including for menopausal hot flashes, have been largely negative for dong quai alone. Its coumarin content raises bleeding risk with anticoagulants.

Safety & interactions

Bleeding risk with warfarin/antiplatelets; photosensitivity. warfarin — Coumarins add bleeding risk.

Bottom line

A traditional women's tonic that underperforms in trials and interacts with blood thinners. Better menopause options exist.
