The skin is the largest organ of the body. The skin and its derivatives (hair, nails, sweat and oil glands) make up the integumentary system. One of the main functions of the skin is protection. It protects the body from external factors such as bacteria, chemicals, and temperature. The skin contains secretions that can kill bacteria and the pigment melanin provides a chemical pigment defense against ultraviolet light that can damage skin cells.
Another important function of the skin is body temperature regulation. When the skin is exposed to a cold temperature, the blood vessels in the dermis constrict. This allows the blood which is warm, to bypass the skin. The skin then becomes the temperature of the cold it is exposed to. Body heat is conserved since the blood vessels are not diverting heat to the skin anymore. Among its many functions the skin is an incredible organ always protecting the body from external agents.
Skin has three layers: 1. The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. 2. The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands. 3. The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.
Some of the skin disorders are rash, dermatitis, alopecia areata, eczema, psoriasis, dandruff, acne, skin abscess, warts, herpes, hives, tinea, shingles, scabies, ringworms, vitiligo, etc.
In modern system of medicine, the drugs often used in the treatment are antibiotics, antivirals, antifungals, antihistamines, analgesics, antipyretics, corticosteroids and immunosuppressives.
These drugs offer good symptomatic relief but have a number of side effects like stomach pain, heartburn, headaches, dizziness, allergic rashes, liver and kidney problems, leg swellings, drowsiness, dry mouth, weight gain, etc. In chronic cases, the treatment is obviously prolonged. The herbal system has a number of medicines that not only provide symptomatic relief but attacks the root cause without any known side effects. Dehlvi has many useful preparations to treat skin disorders.
