This may inhibit prolactin, a natural hormone that acts on the breast. It is touted for breast pain and premenstrual syndrome. There are very few studies in menopausal women. A study of women with premenstrual syndrome found they reported improvements in mood, anger, headache, breast fullness, but not bloating and other symptoms.
This plant produces seeds rich in gamma-linolenic acid, which some experts believe is the nutritionally perfect fatty acid for humans. Although evening primrose capsules are taken for breast pain, bladder symptoms and menopausal symptoms, there is little or no evidence that they work.

A study aimed at reducing hot flashes found that dong quai was not better than placebo - although the 4.5-gram dose used in the study was lower than that typically given in Chinese medicine. The herb is potentially toxic. It contains compounds that can thin the blood, causing excessive bleeding, and make the skin more sensitive to sun, possibly increasing skin cancer risk.
This has traditionally been used as a tranquilizer and sleeping aid. But the U.S. Pharmacopoeia, which sets manufacturing standards for medicines, does not support its use, and there have been reports of heart problems and delirium attributed to sudden withdrawal from valerian.
