Fat Hai Hai can be used as a traditional Chinese medicine, which is cold in nature, and a one-time overdose may lead to abdominal pain, diarrhea, and other gastrointestinal discomfort. The drug source of Fat Hai Hai is the dried mature seeds of Fat Hai Hai (胖大海), a plant in the family of Platycodonaceae, which is sweet in flavor and cold in nature; it is attributed to the Lung and Large Intestine meridians. This medicine has the effect of clearing heat and moistening the lung, inducing pharynx and opening the voice, moistening the intestines and laxatives. It can be used in the treatment of headache and redness of the eyes, lung heat and mute voice, dry cough without phlegm, dry and sore throat, and heat knot stool closure and other diseases. Fatty sea can be boiled water infusion or decoction, but its nature of cold, generally with 2 to 3 can, such as overdose, may lead to abdominal pain, diarrhea and other gastrointestinal symptoms. Therefore, those who have diarrhea and loose stools (thin and unformed stools) with cold spleen and stomach should also be cautious of taking Fat Hai. Chinese medicines should be used under the guidance of a TCM doctor, and should not be used privately to avoid causing damage to the body. If you are not feeling well, we recommend that you consult a doctor promptly to avoid delaying your condition.
