White Peony Root Extract (Paeonia lactiflora) — answers to white peony root extract

Why it’s used

Taken to support menstrual comfort, hormonal balance, and general well-being, drawing on its long history of use in traditional formulas, often alongside licorice root.

What the evidence says

Evidence on white peony root extract taken by itself, in isolation, is thin. Most clinical research involves combination formulas — most notably a paired preparation with licorice root (sometimes called Shakuyaku-kanzo-to) studied for menstrual and hormonal symptoms — rather than white peony extract alone. This makes it hard to attribute any observed effect to peony specifically.

Context

Evidence on this plant appears to exist but could not be verified here to a citable source for the isolated extract. A reviewer looking to resolve this should look for trials of the peony-licorice combination formula, since most published research uses that pairing rather than standalone Paeonia lactiflora extract.
