Our 4 oz Camper's Bar is biodegradable and all natural. Rosemary / Coal Tar Skin and Hair Treatment Soap Bar. This is an improvement on our Rosemary Shampoo Body Bar with the addition of Coal Tar Extract (a natural layer of the Earth's surface). Additionally Jojoba, Aloe Vera, Vitamin E, and Anna's special herbal formula all contribute to the Itch relief. Anna originally developed this bar especially for a friend who suffered from problem-prone skin. Now, after 10 years of production and testing, we are receiving testimonial letters that tell us people have had great results in using it to relieve the symptoms of many skin irritations. In addition to using the bar as a a shampoo or body bar, you may just wet the bar and apply it as a salve to the afflicted area.
