# Chasteberry or Red Clover?

Chasteberry (Vitex agnus-castus) and red clover (Trifolium pratense) are sold for hormone-related complaints, but they target different life stages and their evidence is limited. The table is built from the sourced cards of both herbs.

## Which one, when?

### Chasteberry Seed

Its standardised dry extract may support premenstrual syndrome (PMS) symptoms; studies are mostly positive but at high risk of bias. Use regularly for 3 months; not recommended under 18.

### Red Clover

Its isoflavone extracts have given inconsistent results for menopausal hot flushes; a possible drop in total cholesterol has been reported in menopausal women. There is no confirmed dose for the tea.
