Peony

Peony is recorded in the Donguibogam (Korean traditional medicine encyclopedia) as “stopping various muscle pains.” The Gyeongakjeonseo states it “treats leg muscle cramps and sudden tightness,” making it effective for post-exercise muscle pain and frequent cramping.

Peony’s main component, paeoniflorin, has calming, analgesic, and anticonvulsant properties. In traditional Korean medicine, peony’s “Yugan” effect - softening the liver and muscles - is known to relieve various pains arising from muscles.
