It has been 4 weeks now that I have been useing my 20% Pine Tar soap on the Psoriasis on my knee with no effect what so ever. I am off to the Quack next week so I will see what she suggests. I have read that alchohol abuse agravates Psoriasis yet I have had it on my knee for all of 35 years that I looked at the world through the end of a bottle and it never bothered me. When I stopped drinking 2 years ago was when the psoriasis all of sudden started to itch but not quite enough to encourage me to fall of the wagon. Has anyone had any success with other home remedies? I cant start drinking again as I cant afford both booze and soaping supplies, must mean an addiction is setting in. Steve
