What it does
Licorice root calms inflamed gut, sore throats, spasms, and softens the harsh edges of strong herbs in formulas. In TCM, it supplements qi, your body's vital energy. It also supports the spleen, calms the lungs, and 'harmonizes' other ingredients. It appears in roughly half of all classical formulas. Three systematic reviews track its antiviral and gastric protective effects.

Where it comes from
Licorice (Glycyrrhiza uralensis) is sometimes called 'the king of TCM herbs' because it appears in roughly half of all classical formulas. Its sweet flavor and harmonizing nature make it a near-universal team player. The active glycyrrhizin has cortisone-like anti-inflammatory effects but can cause potassium loss and high blood pressure at high doses or with long-term use. Three systematic reviews track its antiviral and gastric protective effects.
