OK...so the thing is, I like the odd ball things you find to work by accident because you KNOW it's not psychological (all in your mind) if you weren't TRYING to do anything and it happens!
When my son was 5 he had Fifths Disease ("slap face") ....a rash basically that is common in kids....it goes away eventually, it a virus. Anyhow, the doc gave me a hydrocotisone cream for it because it burns and itches pretty badly. Well that cream only relieved him for a few minutes at a time, and seeing as how hydrocortisone cream is one of the few topicals that actually absorbs systematically, I was not comfortable with using so much of it on my 5 year old child (it's a steroid) SO we tried baking soda baths, which didn't work all that well....THEN I thought well soda baths are ph balancing....so are oatmeal baths....maybe they do it differently....so I tried the oatmeal. NOW the bath help a little, but what happened next is the thing. I drained the tub and the oatmeal piled up on the drain so the bath water would not empty. I grabbed a cup and scooped the oatmeal out. The oatmeal was a paste at this point....I thought ...HHMMMM I wonder.....so I went up to my sons room, he was laying there in his undies (which is all he wore while he had this rash because he could not wear anything else, it HURT) I applied some of the paste to a small spot on his leg that was BEAT red with rash....by the time it dried (minutes)that ONE spot was normal colored and did not burn or itch! (it was surrounded by rash where I had not put it....but it worked. I had my son lay on a towel on his bed and spread the paste all over him, told him to lie there until it dried (for 2 reasons, so it would stay on long enough to work, and so he didn't make a huge oatmeal PIE out of his bedroom....he was 5!!lol) IT DISAPPEARED...and stayed gone all night. I repeated this in the morning, and he went off to school and was fine...the rash did not return....
So the moral...oatmeal paste for sever rashing.....not a bath or a store bought lotion...just plain oatmeal turned into a paste...let it soak in warm to hot water for 15-20 minutes then drain the excess water off...WALLA...I do 1/4 oatmeal to 2 cups water just be sure there is enough to completely MUSH it... I'm thinking maybe this would even help yeast rashes...I don't have the skin problems to where I turn red and rashy...I only get DRY skin, but I may try this for that too...it had just occured to me so I thought I'd share!
