Zhi Shi (Immature Bitter Orange)

Zhi Shi (Citrus aurantium), commonly known as Immature Bitter Orange, is a key Qi-regulating herb in Traditional Chinese Medicine (TCM). For centuries, it has been valued for its ability to break up Qi stagnation, reduce accumulation, and relieve fullness in the chest and abdomen.

In classical Chinese herbal medicine, Zhi Shi is frequently included in formulas designed to promote the movement of Qi, relieve digestive stagnation, and support the proper flow of energy in the body.

Because of its strong, downward-directing nature, Zhi Shi is considered an important herb for addressing Qi stagnation and accumulation patterns, especially in the digestive system.
