Zhi Shi (Citrus aurantium), also known as Immature Bitter Orange or Aurantii Fructus Immaturus, is a traditional herb used in Traditional Chinese Medicine (TCM).

Traditional Uses of Zhi Shi in Chinese Medicine
In Traditional Chinese Medicine, Zhi Shi is classified as a Qi Regulating Herb.
Traditionally, it is used to:
• Promote the movement of Qi
• Break up accumulation and reduce fullness
• Support digestive function
• Help regulate patterns of stagnation in the Middle Jiao
• Support downward movement of Qi
In classical herbal theory, Zhi Shi enters the Spleen, Stomach, and Large Intestine channels, where it helps restore balance when Qi stagnation and accumulation disrupt normal physiological function.
Because of these properties, Zhi Shi is widely used in traditional herbal formulas and practitioner herb packs.
