The unique blend of calamine powder we use for this soap is formulated right here from scratch! Our calamine bar soap is intended for use to help alleviate itching and irritation that occurs after working outdoors in any setting. It makes an excellent wash after exposure to poisonous plants such as poison ivy, poisonous oak, wild parsnip etc. Just lather up a cloth of choice and work it in over the affected areas or areas of concern. Repeat as necessary. An excellent addition to your shower or sink as soon as you head for the outdoors in the spring!
