Keep On Hand - Smells Wonderful
I just spent several days removing a large, deep poison ivy patch in a side yard. Quite exhausting but made much safer and easier with this lovely smelling, high quality soap. I did not have ANY skin irritation whatsoever even though I am extremely allergic to Urushiol oil. I did use lots of protective covering and immediately sprayed down with white vinegar first. Then washed up with this very lovely smelling and effective soap. Leaves my skin soft. Would not be without it. Great price. Generous size. Will last a long time stored in its box. Great protective if you wash within 12 hours.

Loved this fresh smelling natural soap for poison ivy rash
I was pleasantly surprised how wonderful & effective this soap is. First of all it smells amazingly fresh and clean. It is soothing on poison ivy rash, it eases the itch, it rinses squeaky clean helping to remove the poison ivy residual oil, and yet it leaves skin soft and smooth. It is also a creamy off white color and not the ugly green brown color pictured in description. I do recommend this high quality natural soap, it is a generous size and a good value, and works well. I loved it!

IT WORKS GREAT for Poison Oak & Poison Sumac
Fantastic soap for my extreme case of Poison Oak & Poison Sumac all over my arms and legs! It helps with the horrible itching. I use it every time I wash my hands to keep the contamination under control. It smells good also. I would highly recommend it! Note: I am also using prescription steroid cream and Ivarest Poison Oak & Poison Sumac wiping pads (also works).

Helps with the itch.
It seems that nothing helps with the itch from an encounter with poison ivy. This product was very good for the itching, it helped me for several hours after my cool shower each day. I would buy this again if the need should arise.

I would never be with out this and calamine lotion!
Good stuff. Try to use it as soon as possible after contact with poison plants. I keep using it until the rash subsides. Leave it on for a few minutes before rinsing. My yard has a lot of poison ivy, so I make sure I always have it on hand.
