WARNING!
Please be careful when using this on severe jock itch, I just used it full strength and it burned like hell for about the 20 minutes I could bare the pain, before I hastily washed it off. However, I hope the pain is a sign its killing the infection. ;)
Tea Tree Oil
★☆☆☆☆
Be careful about using tea tree oil for jock itch, it actually made my condition worse. Maybe give it a try with a small area after a week or so of no improvement please discontinue use.
