Key TCM concepts behind Gan Jiang's properties

In Traditional Chinese Medicine (TCM), Gan Jiang belongs to the 'Herbs that warm the Interior and/or expel Cold' category. Herbs in this category are used for Internal Cold with Qi Deficiency and/or Yang Deficiency. In the Yin and Yang system of thought Yang is Hot in nature. A deficiency of Yang will therefore lead to Internal Coldness since there will as a result be more Yin (Cold in nature) than Yang. In extreme cases this can lead to so-called 'Yang collapse' with convulsions or coma and these herbs are particularly indicated to treat such scenarios.

As suggested by its category Gan Jiang is Hot in nature. This means that Gan Jiang typically helps people who have too much "Cold" in their body. 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 Gan Jiang can help restore a harmonious balance between Yin and Yang.

Gan Jiang also tastes Pungent. The so-called 'Five Phases' theory in Chinese Medicine states that the taste of TCM ingredients is a key determinant of their action in the body. Pungent ingredients like Gan Jiang tends 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.

The tastes of ingredients in TCM also determine what Organs and Meridians they target. As such Gan Jiang is thought to target the Heart, the Kidney, the Lung and the Stomach. In addition to regulating Blood flow, in TCM the Heart is believed to be the store of the 'Mind' which basically refers to someone's vitality. The Kidneys do not only regulate the urinary system but also play a key role in the reproductive system and the growth and aging process of the body. In addition to performing respiration, the Lungs are thought in TCM to be a key part of the production chain for Qi and the Body Fluids that nourish the body. The Stomach is responsible for receiving and ripening ingested food and fluids. It is also tasked with descending the digested elements downwards to the Small Intestine.
