Please note that you should never self-prescribe TCM ingredients. A TCM ingredient is almost never eaten on its own but as part of a formula containing several ingredients that act together. Please consult a professional TCM practitionner, they will be best able to guide you.
Preparation: Remove the smaller fibrous roots and wash, slice and dry.
Dosage: 9 - 30 grams
Main actions according to TCM*: Tonifies the Spleen and Lung Qi. Assists in the secretion of Bodily Fluids.
Contraindications*: This herb should be used with caution when there is acute illness.
Common TCM formulas in which codonopsis roots are used*:
In Traditional Chinese Medicine (TCM), codonopsis roots are plants that belong to the 'Tonic herbs for Qi Deficiency' category. Tonic herbs are used for patterns of Deficiency, when one lacks one of the 'Four Treasures' (Qi, Blood, Yin and Yang). Qi tonics are typically sweet and they tend to enter the Spleen and Lungs because these organs are most involved with the production of Qi.
Furthermore codonopsis roots are plants that are Neutral in nature. This means that codonopsis roots typically don't affect the balance in your body. Balance between Yin and Yang is a key health concept in TCM. Eating too many "Hot" (Yang) ingredients can lead to an imbalance whereby one has a Yang excess. The inverse is true as well: too many "Cold" (Yin) ingredients can lead to a Yin excess. The Neutral nature of codonopsis roots means that you don't have to worry about that!
Codonopsis roots also taste 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. Sweet ingredients like codonopsis roots 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 codonopsis roots are thought to target the Spleen and the Lung. In TCM the Spleen assists with digestion, blood coagulation and fluid metabolism in the body. 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.
An acidic polysaccharide from the roots of Codonopsis pilosula may be a potential candidate compound for the prevention of tumor metastasis, presumably by inhibiting invasion, migration and adhesion of tumor cells, as well as the CD44 expression on the tumor cells.1
