Hua Tangerine Hong does not have fire-reducing properties and may cause fire, and needs to be taken under medical supervision. Hua Tangerine Hong is a traditional Chinese medicine with a warm nature, so taking it in excess or for a long time may cause fire. Its flavor is pungent and bitter, and it belongs to the lung and spleen meridians. It has the effects of regulating qi and broadening the middle (regulating the qi of the spleen and stomach), drying dampness and resolving phlegm (expelling dampness by drying dampness and resolving phlegm). It is used in treating cough with profuse phlegm, food stagnation (accumulation of food in the stomach due to indigestion) and wine, vomiting, nausea and constipation. It should be noted that this product is contraindicated in cases of Qi deficiency, Yin deficiency and dry cough with little phlegm. The clinical manifestations of fire can be mild or severe, and common severe cases such as heatstroke are typical signs of exogenous fire-heat. While the commonly known “fire” is generally lighter, mostly belongs to the mild symptoms of heat in Chinese medicine, such as red and swollen eyes, erosion of the corners of the mouth, yellow urine, toothache, sore throat and so on, which are not accompanied by systemic symptoms of heat. If the symptoms of fire occur when taking tangerine red, you should suspend taking it. The effect of a single drug is limited, and when taking tangerine red, you should consult a professional Chinese medicine doctor first to avoid discomfort or delay in the condition.
