When people eat eggplants, they often cut off and discard the calyx, but in the view of Traditional Chinese Medicine, the calyx is also a rare and valuable medicinal herb. Don't overlook its medicinal properties when eating eggplants.
Eggplant itself is a food with a cool nature, and the calyx is even cooler. Traditional Chinese Medicine teaches that medicinal herbs with a cool nature have the effect of clearing heat and detoxifying. For instance, with intestinal wind and bleeding, such as hemorrhoidal bleeding, or toothaches and body sores, which indicate an internal "fire" or excess heat, the eggplant calyx can be used to clear heat and detoxify. If you feel you have "heatiness" and happen to have fresh eggplants at home, you can simply cut off the calyx and add it to your dish to alleviate the condition. Decocting or brewing fresh eggplant calyx with Coptis, Phellodendron, or the lotus plumule into a tea can treat mouth sores.
