Common TCM formulas in which dittany root bark are used*:
In Traditional Chinese Medicine (TCM), dittany root bark are plants that belong to the 'Herbs that clear Heat and dry Dampness' category. Herbs in this category are used to clear inflammatory and infectious conditions, referred to as 'Internal Heat' in TCM. This is why most of the herbs in this category will have both antibacterial and antiviral properties. In TCM one has too much 'Heat' in their body as a result of a deficiency of 'Yin' (which is Cold in nature, see our explanation on Yin and Yang) or, more commonly, an excess of Yang (Hot in nature). Herbs that clear Heat and dry Dampness treat the latter while, at the same time, relieving the body of excess Dampness. As such they tend to be Cold or Neutral in nature.
As suggested by its category dittany root bark are plants that are Cold in nature. This means that dittany root bark typically help people who have too much "heat" in their body. Balance between Yin and Yang is a key health concept in TCM. Those who have too much heat in their body are said to either have a Yang excess (because Yang is Hot in nature) or a Yin deficiency (Yin is Cold in Nature). Depending on your condition dittany root bark can help restore a harmonious balance between Yin and Yang.
Dittany root bark also taste Bitter. 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. Bitter ingredients like dittany root bark tend to have a cleansing action on the body by clearing heat, drying dampness and promoting elimination via urination or bowel movements.
The tastes of ingredients in TCM also determine what organs and meridians they target. As such dittany root bark are thought to target the Bladder, the Spleen and the Stomach. In TCM the impure water collected by the Kidneys that cannot be used by the body is sent to the Bladder for storage and excretion as urine. The Spleen on the other hand assists with digestion, blood coagulation and fluid metabolism in 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.
