You may already have some treatments for psoriasis in your pantry or bathroom cabinet. Some sufferers of psoriasis find that bath treatments are effective in providing relief from soreness, itchiness, redness and scaling. Add oatmeal, oil, epsom salts or Dead Sea salts to your bath. It may help your skin to shed scales and ease itching caused by psoriasis. When using this treatment, soak in your bath treatment for about 15 minutes. After your bath, apply a moisturizer or oil to your skin to seal in water and prevent your skin from drying out.
You also can use readily available FDA-approved anti-itch ingredients such as calamine, hydrocortisone, camphor, diphenhydramine hydrochloride (HCl), benzocaine and menthol to soothe itching associated with psoriasis.
