There is no dandelion water to drink the three major taboos, but too much can lead to slow diarrhea, so the spleen and stomach cold (spleen and stomach weak cold), loose stools (feces thin not shaped) diarrhea is not recommended to take dandelion. The efficacy of dandelion in water is limited, and the therapeutic effect of a single medicine is not good. It is recommended to have a professional doctor to identify the symptoms and formulate a prescription, and reasonably match with other medicines to improve the therapeutic effect. Dandelion is bitter, sweet, cold in nature, and belongs to the liver and stomach meridians. It has the effects of clearing heat and removing toxins (removing heat and toxins from the body), subduing swellings and dispersing lumps, and inducing diuresis and diaphoresis (improving the problem of incomplete urination and small amount of urination). Dandelion can be used to treat lung carbuncle, intestinal carbuncle (carbuncle that occurs in the intestines and bowels, manifested by fever, right abdominal pain and palpable lump), breast carbuncle, damp-heat jaundice, feverish gonorrhea (burning and tingling pains during urination, accompanied by frequent urination and urgency, and discomfort of pulling in the abdomen), astringent pain, and redness and swelling of the eyes. After the discomfort should be timely medical treatment, in the physician’s evidence under the guidance of the choice of drug treatment, not self-medication, so as not to delay the condition.
