The epidermis, the body's true envelope, protects against heat, cold, infections, and shocks. The skin constantly regenerates, but its maintenance requires hygiene and good nutrition. Its ability to protect and heal depends, in fact, on the body's general condition. Many benign skin conditions are treated with simple external medication. But serious or chronic disorders often require internal treatments in addition to medical advice. Bites and stings frequently cause swelling-and inflammation-on the skin's surface. Most cause only local itching and temporary irritation. The remedies mentioned contain soothing and anti-inflammatory properties. Combining internal and external treatments improves results.
