According to Chinese medicine, boils are caused by the invasion of heat toxins into the skin, and are also called “heat boils” because they belong to the category of sores and heat. It is a purulent infection of the hair follicle and the deeper surrounding tissue of the hair follicle. Boils can be caused by bacterial infections, dietary allergies, life stress, poor resistance, certain medications, junk food, wound infections, blood poisoning, and other factors. The initial symptoms of boils are red, swollen, and very painful. They become pus after a few days and then break down, and the pain will be relieved when the pus breaks. Boils are most common on the head, face, neck, back, buttocks, and mainly on the face, fingers, and toes. Individual boils are absorbed by the surrounding tissue. In most cases, the boil can be healed within 2 weeks. It is important to pay attention to the cleanliness of the skin and never squeeze and pinch the pus, especially the boils on the face and upper lip, which can easily cause staphylococcus to invade the hair follicles, sebaceous glands and subcutaneous tissues, and then become pus. If the boil has already become pus, it must be allowed to mature and break down, and the pus will flow out before it can gradually heal. Pay attention to skin hygiene, forbid spicy and irritating food and alcohol, and preferably do not eat more sweet food. For recurring boils, it is important to look for underlying factors and eliminate infected lesions and causative factors in the body. If you have anemia or diabetes, treat the underlying disease promptly. Boils are small, but their prevention and treatment should not be neglected. They are painful and unsightly, and sometimes leave scars, which can occasionally be dangerous.
