The physiological end of regular menstruations is often accompanied by mood changes, hot flushes, night sweats, insomnia, vaginal dryness, decreased libido, impairment of cognitive function, and other symptoms.
The exact cause of most of these complaints is still not completely understood. Concerns about HRT have recently emerged and many women are keen to try complementary therapies for controlling these troublesome symptoms. Herbal supplements and homeopathy seem particularly popular.
Clinical bottom line
Likely to be beneficial
• Ginkgo (Ginkgo biloba) Data suggest that it improves cognitive function in menopausal women but no effect on menopause-associated depression.
• Red clover (Trifolium pratense) Seems to reduce the frequency of hot flushes.
• St John's wort (Hypericum perforatum) Seems to improve mild-to-moderate depression.
• Relaxation Preliminary data imply positive effects on hot flushes but it is unclear which type of relaxation is best.
Trade-off between benefits and harms
• Black cohosh (Actaea racemosa) Seems to reduce depression and improve sleep quality but data on vasomotor symptoms are contradictory and it has been associated with liver damage.
• Kava (Piper methysticum) Seems to reduce anxiety but has been associated with liver damage.
• Acupuncture Results are contradictory for symptom control.
• Fennel (Foeniculum vulgare), a pollen extract Reduces hot flushes, according to preliminary data.
• Osteopathy Not enough data available for hot flushes.
• Soy/phytoestrogens Data highly contradictory for symptom improvement.
• Vitamin E Data contradictory.
Unlikely to be beneficial
• Ginseng (Panax ginseng) No improvement of quality of life, hot flushes or vaginal cytology.
Likely to be ineffective or harmful
• Dong quai (Angelica sinensis): No evidence of effectiveness.
• Evening primrose (Oenothera biennis) oil: no evidence of effectiveness for bone density, hot flushes.
• Kudzu (Pueraria lobata) No evidence of effectiveness.
• Wild yam (Dioscorea villosa) No evidence of effectiveness.
Ginkgo, red clover, St John's wort, relaxation, black cohosh and kava may be effective in relieving menopause-associated symptoms such as hot flushes and depression.
Black cohosh and kava have been associated with liver damage. Interactions of St John's wort need to be considered. None of the other treatments are burdened with serious risks.
The risk-benefit balance for ginkgo, red clover, St John's wort and relaxation is likely to be positive.
Conventional HRT is supported by stronger evidence than complementary and alternative therapies for controlling menopausal symptoms.
