Side effects of Radix Codonopsis pilosulae are not clear, but it should be used with caution and should not be used with Veratrum if there is stagnation of qi (poor flow of qi), liver fire, or if there is an abundance of evil but not a deficiency of righteousness. Codonopsis pilosula is a common qi tonic herb, sweet and flat in nature, belonging to the spleen and lung meridians, with the effects of strengthening the spleen and tonifying the lungs and nourishing the blood and generating fluids. It is mainly used for treating symptoms such as deficiency of the spleen and lungs, poor appetite and fatigue, palpitation (rapid heartbeat often accompanied by panic attacks), shortness of breath, or internal heatiness and thirst (internal fever accompanied by symptoms such as excessive eating and drinking, and excessive urination). Dangshen is usually taken in soups, decoctions, or in bulk or pills, but Dangshen should not be used with quatrefoil and should not be used with caution in cases of stagnation of qi and exuberant liver fire, and should not be used on its own by pregnant women, lactating women, or children. It is recommended to take this medicine under the guidance of a professional Chinese medicine practitioner, and should not be used arbitrarily or listen to traditional Chinese medicine prescriptions.
