Those with a hot heart will have a red complexion, a protruding pulse, sores in the mouth, and a foul smell caused by rot. They will also experience pain in the chest, diaphragm, shoulders, back, flanks, and arms. When the heart is empty, it causes pain in the heart and abdomen, or dreams of knives, staffs, flames, red clothes and red objects, or matters of stove treatment, to scare and bewilder people. When there is a heart disease that needs to be moistened, one should eat salty food to moisten it, use bitter food to nourish it, and use sweet food to purge it. Avoid wet clothes and hot food. The heart dislikes heat and water. When there is an artery above the navel in a heart disease, press it firmly. If the pain is more bitter, irritable and decocted, the palms and soles are hot, the mouth is dry and the tongue is strong, the throat hurts and cannot be swallowed, and one forgets the past and the future.
