Dandelion can be used as a traditional Chinese medicine, which is non-toxic and generally does not cause the body to experience uncomfortable symptoms or toxic reactions when used reasonably. Dandelion is the dried herb of dandelion, alkali dandelion, or several other plants of the same genus in the Asteraceae family. It is bitter, sweet, cold and non-toxic, and has the effects of clearing heat and removing toxins (clearing away heat and toxicity in the body), subduing swellings and dispersing lumps, and diuretic and diaphoretic (improving the problem of dribbling and urination, or the problem of urinary volume and incomprehensible urination). It can be used in the treatment of carbuncle furuncle (a skin disease that refers to severe furuncle), breast carbuncle, sore throat, heat drenching (burning and stinging pain during urination, accompanied by frequent urination and urgency, and discomfort of traction in the abdomen), astringent pain and other conditions. It should be noted that, although dandelion does not lead to poisoning, but its bitter and cold taste, should not be used in excess, so as not to damage the spleen and stomach, diarrhea and other gastrointestinal symptoms, the specific use should be in the physician’s diagnosis under the guidance.
