Itching, medically called pruritus, is a discomforting symptom associated with various disorders of the skin. Itching may be limited to a small area of skin or involve the whole body and is commonly associated with redness, swelling and heat. Some of the important causes of itching include xerosis or dryness of skin, atopic dermatitis (eczema), allergy, medicines containing opioids, skin infections (e.g., fungal infections, scabies, lice), urticaria (hives) and insect bites. Systemic causes include kidney failure, liver problems, HIV infection, cancer (e.g., Hodgkin’s lymphoma, melanoma), infections (e.g., filariasis, schistosomiasis), nerve problems (e.g., peripheral neuropathy, shingles), autoimmune disorders (e.g., scleroderma, psoriasis, lichen planus), diabetes mellitus and varicose veins. Chronic mental stress, anxiety and depression are also considered as important risk factors for various skin disorders that result in itching. Dermatologists commonly prescribe moisturisers, medicated ointments or creams and oral medications (e.g., antihistamines, steroids) for the treatment of itchy skin.
In homoeopathy, medicines such as arsenicum album, sulphur, apis mellifica, graphites, mezereum, silicea, urtica urens and rhus toxicodendron are frequently used for the treatment of the distressing symptom of itching. Appropriate homoeopathic medicine is selected by a qualified homoeopathic physician on the basis of the individual symptoms and it mainly aims at treating the cause of the disease so as to provide long-term relief to the patient.
