It is generally not recommended to boil dandelion and ginger together, because the two properties of the medicine a cold and a warm, relative medicinal properties, together with the water may not be able to play out the original effect of Chinese medicine. 1. Dandelion has the effect of clearing heat and removing toxins, subduing swelling and dispersing knots, diuretic and diaphoretic (to improve urinary dribbling, urinary volume of the problem). Dandelion can be used for furuncles (sores mostly occurring on the limbs or face, small in shape with deep roots, as hard as nails) swelling and poisoning, breast carbuncle, scrofula (mainly refers to cervical lymph node nodules tuberculosis), redness of the eyes, and sore throat. This product can also be used for lung carbuncle, intestinal carbuncle (carbuncle occurring in the intestines and bowels, manifested by fever, pain in the right abdomen, and palpable lumps), damp-heat jaundice and so on. Excessive use can lead to slow diarrhea. 2. Ginger has the effect of relieving surface cold (removing cold from the surface of the muscle), warming and stopping vomiting (treating vomiting caused by stomach cold by warming the spleen and stomach), resolving phlegm and relieving cough, and detoxifying fish and crab. Ginger can be used for wind-cold cold, vomiting with cold stomach, coughing with cold phlegm, fish and crab poisoning. It should not be used in too large a quantity and should not be decocted for a long time. When used to relieve water retention and swelling, it should be used in a slightly larger quantity and should be decocted in a thicker form. This product is strong in pungent and warm sweating, and should not be used by those who have sweating on the surface. Therefore, the two properties are opposite, it is not recommended to boil water together. It should also be noted that the efficacy of Chinese medicine boiled water is limited, and can not replace the Chinese medicine prescription to treat the disease. If there is any discomfort, consult a doctor in time, and follow the doctor’s instructions to use the medication.
