Eating sugar after taking Chinese medicine is generally possible, but should not be consumed in large quantities, and diabetic patients should not eat sugar. As Chinese medicine is bitter, eating sugar after taking Chinese medicine can relieve the bitter taste in the mouth. There is no clear contraindication in Chinese medicine for eating sugar after taking Chinese medicine, but you should eat a small amount of sugar but not a large amount. If the Chinese medicine contains sugar, i.e. sugar as part of the prescription, such as caramel in Dajianzhongtang or Xiaojianzhongtang, then it is best not to eat sugar after taking the Chinese medicine, in order to prevent the dosage from deviating and affecting the therapeutic effect. Eating sugar is not recommended if you are a diabetic to prevent high blood sugar. In addition to eating sugar to relieve the bitter taste in the mouth, you can also choose to gargle with warm water for relief. During the period of taking Chinese medicine, you should eat a light diet and avoid spicy and stimulating, cold and greasy food. Whether you can eat sugar after taking Chinese medicine should be decided by the prescription issued by the doctor after a clear diagnosis, so as to avoid any influence on the efficacy of the medicine or fluctuation of blood sugar.
