It is generally acceptable to consume moderate amounts of corn while taking traditional Chinese medicine (TCM), but this should be determined based on the specific medical condition and the composition of the herbal prescription. Each individual has a different body constitution, and responses to food and medication may vary. Corn, as a common whole grain, contains abundant nutrients such as dietary fiber, protein, vitamins, and minerals, which are beneficial to health and generally do not interfere with TCM. However, if the TCM formula contains specific dietary contraindications or the medical condition requires strict dietary control (e.g., in patients with diabetes or indigestion), corn intake should be monitored due to its relatively high starch and sugar content, which may affect blood glucose levels or digestion.

It is recommended that daily corn intake not exceed 100 grams and that it be used as a partial substitute for staple food. Avoid consuming corn on an empty stomach or in excessive amounts. Choose easily digestible cooking methods such as boiling or steaming, and minimize consumption with greasy foods. Allow at least one hour between medication intake and eating to avoid interference with TCM absorption. If discomfort such as abdominal bloating or acid reflux occurs after taking the medication, reduce corn consumption or consult a physician to adjust the prescription. Diabetic patients should note that corn has a high starch content and should be included within the total daily carbohydrate intake. During long-term调理 (regulation), the diet should primarily be light and balanced, incorporating spleen-nourishing ingredients such as Chinese yam and millet, while avoiding raw, cold, or spicy foods that may burden the spleen and stomach. If the body constitution is unique or the herbal prescription contains special contraindications, follow medical advice to adjust the dietary regimen.
