Common TCM formulas in which cinnamon twigs are used*:
In Traditional Chinese Medicine (TCM), cinnamon twigs are plants that belong to the 'Warm/Acrid herbs that release the Exterior' category. Herbs that release the Exterior aim to to treat the early stages of diseases that affect the upper respiratory tract, the eyes, the ears, the nose, the throat or the skin. TCM believes that External diseases such as colds or allergies can only invade the body if the External environment overwhelms our Wei Qi (the TCM version of the immune system). In order to counteract this invasion Warm/Acrid herbs aim to induce sweating by increasing the flow of sweat to our capillary pores. The belief is that this will expel the disease from the body and stop it from invading further.
As suggested by its category cinnamon twigs are plants that are Warm in nature. This means that cinnamon twigs tend to help people who have too much "cold" in their body, although with less effect than a plant that would be Hot in nature. Balance between Yin and Yang is a key health concept in TCM. Those who have too much cold in their body are said to either have a Yin excess (because Yin is Cold in nature) or a Yang deficiency (Yang is Hot in Nature). Depending on your condition cinnamon twigs can help restore a harmonious balance between Yin and Yang.
Cinnamon twigs also taste Pungent and Sweet. The so-called "five elements" theory in Chinese Medicine states that the taste of TCM ingredients is a key determinant of their action in the body. Pungent ingredients like cinnamon twigs tend to promote the circulations of Qi and body fluids. That's why for instance someone tends to sweat a lot when they eat spicy/pungent food. On the other hand Sweet ingredients tend to slow down acute reactions and detoxify the body. They also have a tonic effect because they replenish Qi and Blood.
The tastes of ingredients in TCM also determine what organs and meridians they target. As such cinnamon twigs are thought to target the Spleen, the Heart and the Lung. In TCM the Spleen assists with digestion, blood coagulation and fluid metabolism in the body. In addition to regulating blood flow, the Heart is believed to be the store of the "spirit" which basically refers to someone's vitality. In addition to performing respiration, the Lungs are thought to be a key part of the production chain for Qi and the body fluids that nourish the body.
