In classical Chinese herbal medicine, Zhi Zi is frequently included in formulas designed to clear heat from the heart, liver, and lungs, relieve restlessness, and eliminate toxic heat from the body.
Because of its ability to both clear heat and calm agitation, Zhi Zi is considered an important herb for addressing heat-related irritability and internal restlessness.
