I have suffered with psoriasis from the age of 6 and tried a variety of medications, oils, creams, pastes and even chinese medicine! You name it, I've tried it. My problem is moderate and is confined to scalp, knees and elbows which normally get worse with the onset of Winter. My husband bought me some Balneum bath oil (soya oil) which was on special offer at Sainsburys. Although I don't use it in the bath, I have a warm shower then rub a small amount on my skin while its still wet and pat my skin dry. I have used this for about four months now and I can't believe the result. The red flaky patches that I normally get have almost gone. It must be because the oil traps the moisture which is normally lost particulary in the cold weather. I just wanted to recommend this to other psoriasis sufferers - it may not cure yours, but it's worth trying. Good luck!
