The term “on fire” is a folk term, also known as “excessive internal heat” or “hot air” and is explained by TCM theory as a category of heath syndrome. According to TCM theory, when the body’s Yin and Yang are out of balance and internal heat is strong, the body suffers from excessive internal heat. 

Some symptoms include: red and swollen eyes, yellow pee, toothache, sore throat, nosebleeds and insomnia. It’s more likely to occure in dry or hot and humid days. To “remove the heat” means to nourish and detox Yin. 

Therapies to help eliminate heat are acupuncture, cupping and tui nai massage. It’s also important to balance life + work and to eat less spicy and fried foods.
