Oil of oregano on skin rashes?

can u put oil of oregano on your skin to get rid of a rash? i heard it works similiar to tea tree oil? will it burn and dry out your skin? or will it actually work? i am very curious i have a rash on my face and allergic to most skin things.....|||it might burn so be careful. Mix it with something like olive oil to dilute it. Dap with a q-tip to see how it feels first,|||try Benedryl cream and a visit to your doctor.
