Is it okay to eat some biscuits before drinking Ganmaoling granules?
Generally, it is acceptable to drink Ganmaoling granules 15–30 minutes after eating plain biscuits. However, this is not recommended if the biscuits are greasy or overly sweet, or if you have a sensitive digestive system. If in doubt, it's best to consult a doctor in advance. Detailed analysis is as follows:

If you consume plain soda crackers or unflavored biscuits and have normal gastrointestinal function, drinking Ganmaoling granules 15–30 minutes afterward typically poses no significant issues. Plain biscuits can slightly neutralize gastric acid, reducing direct irritation of the medication on the gastric mucosa, and do not interact adversely with the drug’s ingredients, thus not affecting its efficacy.
However, if you eat greasy, overly sweet, or filled biscuits, or if you have weak gastrointestinal function (such as being prone to bloating or acid reflux), it is not advisable to take Ganmaoling immediately afterward. These types of biscuits increase the digestive burden on the stomach and intestines; when taken together with the medication, they may cause discomfort such as nausea or bloating. Additionally, excessive sugar content may affect the absorption rate of the drug, indirectly reducing its therapeutic effect, or even worsening throat discomfort.
Before taking Ganmaoling granules, opt for light, non-greasy, and non-spicy foods. If you have eaten biscuits, wait a while before taking the medication—do not take it immediately. During treatment, drink plenty of warm water to promote drug metabolism and recovery from the cold. If gastrointestinal discomfort or allergic reactions occur, discontinue the medication promptly and seek medical attention.
