Glycyrrhetinic acid granules are a class A over-the-counter drug, which is taken orally. Class A over-the-counter drugs need to be purchased in pharmacies with licensed pharmacists and purchased and used under the guidance of licensed pharmacists or herbalists, mainly for the treatment of anorexia or anorexia nervosa, stunted growth in children caused by zinc deficiency, and also for the treatment of acne vulgaris and mouth ulcers. As this medicine treats diseases caused by zinc deficiency, there are also acne vulgaris, mouth ulcers, etc. The mouth ulcers are still very good, but the other two are not so good, so you need to buy and use it under the guidance of a physician or pharmacist. Two points should be noted in the process of using the drug: first, be sure to read the drug instructions in detail to clarify the contraindications, adverse reactions, and important matters and precautions; second, after using the drug for a period of time, be sure to observe whether the symptoms are relieved, and if they are not relieved or aggravated, you should go to a medical institution in time to follow up and receive regular treatment.
