Chuanbei Loquat Paste is mainly composed of Chuanbei mother extract, Eryngium, loquat leaf, menthol, maltose, sodium benzoate and almond flavor. The instructions suggest that the side effects of the drug are unclear. By analyzing the main components of Chuanbei loquat extract, the possible side effects of the drug are considered to be skin allergy, hypoglycemia, central nervous system reactions (psychosis), respiratory system reactions (pulmonary edema, lung injury, lung cancer, and asthma), digestive system reactions (irritant effects as well as inflammation.) , cardiovascular system reactions, liver cirrhosis, etc. There is a case of skin allergy caused by oral consumption of Chuanbei mum, which is considered to be a phlegm-relieving, cough-relieving and asthma-relieving drug in the literature. Taste and Attribution: Bitter, sweet and slightly cold, belongs to the lung and heart meridians. Effects: Clearing heat and resolving phlegm, moistening the lung and relieving cough, dispersing nodules and subduing swelling. Modern research found that the drug contains a variety of alkaloids, which can dilate the bronchial smooth muscle and reduce airway secretion, so it has a good cough expectorant effect. According to the process of drug administration, clinical manifestations and effective anti-allergic treatment of the child, it is consistent with drug-induced allergic reactions. The literature reported a case of repeated hypoglycemia caused by the heavy use of E. oryzae in a traditional Chinese medicine formula. The literature suggested that in addition to its expectorant and cough suppressant effects, its water or alcohol extract could cause a decrease in blood glucose in rabbits after internal administration. This literature emphasizes that Eustoma can induce hypoglycemia, which arises not only from a slightly higher dosage but also from individual differences. It should be taken seriously. However, the dosage of Platycodon grandis in the composition of Chuanbei Loquat Paste is not specified in the drug’s instructions, so it is debatable whether the drug may cause hypoglycemia. The safety of menthol, also known as menthol, a saturated cyclic terpene alcohol found in peppermint and spearmint essential oils, has been studied in the literature. The literature concluded that menthol was considered non-toxic and harmless in the prescribed dose range (0-012 mg/kg/day) when it was widely used as an aromatic agent and flavoring, but with the widespread and extensive use of its adverse reactions have occurred, the literature also summarized the adverse reactions of menthol as allergic reactions, central nervous system reactions (psychosis), respiratory reactions (pulmonary edema, lung injury, lung cancer, and asthma), digestive reactions, and asthma. The literature also summarizes the adverse reactions of menthol as allergic reactions, central nervous system reactions (psychosis), respiratory reactions (pulmonary edema, lung injury, lung cancer, and asthma), digestive reactions (irritation and inflammation), cardiovascular reactions, and cirrhosis. Again, since the amount of mint in the ingredients of Chuanbei Loquat Paste is not specified in the drug’s instructions, it is debatable whether the drug may cause these side effects.
