Patients with cheilitis can drink Pu'er tea. The exact causes of cheilitis are not entirely clear, but clinically, it is generally believed to be related to environmental irritants, allergic factors, poor lifestyle habits, and the irritation of certain foods. However, tea itself does not cause allergic reactions. Patients with cheilitis should eat foods that are antibacterial, anti-inflammatory, detoxifying, and rich in high-quality proteins, and they should avoid oily, spicy, and irritating foods. Tea is neither spicy nor overly greasy, and it is relatively beneficial for health. Therefore, it is acceptable for patients with cheilitis to drink some Pu'er tea appropriately.
