My guess would be either poly cystic or fungal infection or toxins in pores .The oregano works on bacteria ,fungus ,and is also an antiparasitic .Its basically a all natural Antibiotic of the broad spectrum variety .Same thing with the garlic .Another good one is olive leaf extract .Im also taking MSM internally and it is great for your skin and detox .As bad as I feel with my illness my skin looks great now ,ha ha
