Bitter Orange
Bitter Orange (Zhi Ke): A Qi-Regulating Herb for Bloating, Digestion, and Chest Discomfort
Introduction
Bitter orange, known as Zhi Ke (枳壳) in Traditional Chinese Medicine (TCM), is a mild, qi-regulating herb used to promote the movement of qi, relieve distension, and support digestive function. With its slightly bitter and cool nature, Zhi Ke is particularly suited for cases of qi stagnation involving bloating, belching, chest tightness, or sluggish digestion. It’s often used alongside stronger herbs to gently regulate internal pressure without causing excessive purging.
What Is Bitter Orange?
Zhi Ke refers to the mature dried peel of Citrus aurantium, the bitter orange fruit. It is classified in TCM as bitter, acrid, and slightly cold, entering the Spleen and Stomach meridians. Traditionally, Zhi Ke is used to promote the movement of qi, resolve stagnation, and aid in regulating bowel function. It is a gentler counterpart to Zhi Shi (immature bitter orange), making it especially suitable for individuals with weaker constitutions or chronic digestive issues.
Health Benefits of Bitter Orange

Zhi Ke helps move stagnant qi in the middle burner, easing fullness and bloating in the abdomen or chest.

Often used to promote appetite, reduce belching, and support smoother digestion.
Gently Unblocks the Bowels
It mildly stimulates bowel movements, especially in cases of constipation caused by qi stagnation.
Relieves Chest and Rib-Side Discomfort
Zhi Ke alleviates feelings of distension or tightness in the chest caused by blocked qi or phlegm accumulation.

It is often paired with herbs like Bai Zhu or Hou Po to harmonize the digestive system in broader qi-regulating formulas.
