Product Research:    The manufacturers take pride in this oil being the only oregano product on the market extensively researched.  Studies conducted by Georgetown University in Washington, D.C., have shown that the wild, mountain-grown oregano used by North American Herb & Spice is an excellent anti-fungal agent, completely killing Candida albicans in concentrations as minimal as 0.25 mg/ml. It also is much safer to use than popular anti-fungal drugs on the market. Further studies are pending. Many studies demonstrating the strong antioxidant, broad antimicrobial and even painkilling properties of oregano have been published in scientific journals.
