The exact pathophysiology and curative treatment of many common dermatologic conditions remain unclear. Often conventional treatments are only partially effective, leading patients to look for alternative treatments. Rosacea may be helped by azelaic acid. Seborrheic dermatitis may be helped by tea tree oil. Chronic urticaria may be helped by a focused dietary history and elimination of food additives and salicylates. Although various alternative treatments have been touted as useful in herpes simplex, few have proved efficacious.
