Concerns

What it does

White peony eases muscle cramps, painful periods, tension headaches, and rib-side tightness from stress. In TCM, it nourishes blood and softens a 'tight liver,' the pattern behind irritability and physical clenching. It pairs with Dang Gui in Si Wu Tang for blood, and with licorice in Shao Yao Gan Cao Tang for spasms. Two reviews track its dysmenorrhea uses.

Where it comes from

White peony (Paeonia lactiflora) is the cultivated peony grown for its medicinal root, distinguished from red peony (Chi Shao) which moves blood more aggressively. White peony nourishes and softens. The root is harvested after 3–5 years of growth, then peeled and boiled. It's the lead herb in two famous formulas: Si Wu Tang for blood deficiency and Shao Yao Gan Cao Tang (with licorice) for spasms and cramping pain. Two reviews track dysmenorrhea outcomes.
