skin and structure infection
"I had a heat rash in my groin and it was red and very irritating. I used a small amount if the ointment twice a day after showering. Within 24 hours, the irritation was bearable, within 48 hours the irritation had stopped and within 72 hours the redness had faded. I still have dull red marks where the skin was damaged but the rash has totally gone. This, is a fantastic product for heat rash and also, if you have an insect bite, it stops the itching within 2 minutes. 
Can be bought over the counter in most Asian countries. Cost here in the Philippines is 299 pesos or around $7. Bargain!"
