In clinical practice, dietary restrictions for folliculitis due to lung heat typically include avoiding or reducing the intake of spicy, greasy, and cold foods. The so-called spicy foods refer to hot pots, barbecues, and dry pots, especially those containing cumin, chili, and Sichuan pepper. These aromatic and spicy foods should not be consumed. What are cold foods? Examples include ice cream and popsicles, as these can transform dampness into heat, thus such cold foods should also be avoided. Greasy foods include rich oil-based soups or broths, which are also not suitable for consumption during folliculitis.
