Which herbs have the best evidence for PCOS?

Inositol, cinnamon, spearmint and berberine have the most published human data in PCOS specifically, mostly for insulin sensitivity, androgen levels or cycle regularity. Evidence quality varies a lot by herb, and each guide in this index says what was actually measured rather than what the herb is marketed for.

Can herbs replace medication for PCOS?

No. Nothing in this index is a substitute for prescribed treatment, and some herbs interact with medications including metformin and hormonal contraceptives. Talk to your doctor or pharmacist before adding anything, particularly if you are on a prescription or trying to conceive.

Do herbs work without dietary change?

The evidence is weakest where diet is unchanged. Most of the mechanisms these herbs act on, insulin sensitivity above all, respond far more to what is on the plate at every meal than to a daily capsule.
