Trish, I am allergic to castor bean plants. When the sap got on my skin I got giant hives. Needless to say, I have not gotten within 50 feet of a castor bean plant since then (& that's when I was 6). I see there is castor oil in your soap. This is true of many handmade soaps & I see Burt's Bees has it in a lot of their products. I've also seen it listed in "natural" lipsticks & makeups. I will not touch any products that use it. Am I being overly cautious? I would like your opinion.
