The evidence in words
The verdict
For pms, Vitex (Chasteberry) earns evidence grade B (unclear effect, mixed consistency) — there is real evidence here. Across cycles
How it might work
It has dopaminergic activity that lowers prolactin, influencing the luteal phase and related symptoms.
How to use it
Standardized extract (e.g., ~40 mg) daily across the cycle; give it 2–3 cycles.
Safety & cautions
Generally tolerated; its prolactin/dopamine action means caution with dopaminergic drugs, hormonal contraception, and in pregnancy.
Bottom line
A genuinely useful PMS and breast-pain botanical. Take it daily across a few cycles; mind the hormonal/dopaminergic interactions.
How it is used
As the entry records it, from the studies it summarises. Not a recommendation for you — doses that suit a trial population may not suit you.
- Standard
- ~40 mg standardized daily, 2–3 cycles.
