For those who suffer from internal heat and yellow urine, they can choose to take the proprietary Chinese medicine Guanchi Pills. The proprietary Chinese medicine Guanchi Pills is made from the formula Guanchi San, which is from the book “Direct Record of Pediatric Medicines”. The original formula is for treating yellowing of urine and heart caused by internal heat in pediatrics, and later evolved to treat yellowing of urine and heart caused by internal heat in people of all ages. The formula is composed of Radix Rehmanniae Praeparata, Radix Mouton, Radix et Rhizoma Glycyrrhizae Praeparatae, Radix et Rhizoma Bamboo Leaves, which can purify the heart, diuretic and nourish yin. It is mainly used for treating heart meridian fire-heat syndromes, with the common symptoms of irritable heat in the heart and chest (irritability and sullenness), redness of the face due to thirst, soreness of the mouth and tongue, stinging pain in the urine with yellowish redness of the tongue, and reddish pulse. Note that Mutong in the formula is bitter and cold, and Shengdi is Yin-soft and cold, so it should be used with caution for those with weak spleen and stomach. If symptoms such as internal heat and yellow urine appear, it is recommended to go to the hospital in time and use the medicine under the guidance of a doctor.
