Cassia Twig Chinese Herb
Cassia Twig (Gui Zhi): A Warming Herb for Circulation, Surface Conditions, and Yang Deficiency
Introduction
Cassia twig, known as Gui Zhi (桂枝) in Traditional Chinese Medicine (TCM), is a warming and gently dispersing herb used to release the exterior, warm the channels, and invigorate yang qi. Derived from the tender branches of the cinnamon tree, Gui Zhi is commonly used in formulas for colds with wind-cold symptoms, muscle stiffness, or poor circulation. Its aromatic warmth also makes it effective for harmonizing the flow of qi and blood in both acute and chronic conditions.
What Is Cassia Twig?
Gui Zhi refers to the young twigs of Cinnamomum cassia, the same plant used to make Chinese cinnamon bark. In TCM, it is classified as acrid, sweet, and warm, and it enters the Heart, Lung, and Bladder meridians. Traditionally, cassia twig is used to release the exterior (especially wind-cold), warm the middle and extremities, and support proper circulation of fluids and blood. It plays a key role in both harmonizing and invigorating herbal combinations.
