Oregano is perhaps the most powerful herbal anti-fungal agent known. Its effectiveness is enhanced by its safety, since it is entirely non-toxic. This is of crucial important with disseminated fungal infections, such as Candidiasis, since large doses may be necessary to establish a cure. Furthermore, fungal resistance to oregano is exceptionally rare. Oregano is such a potent anti fungal agent that it is capable of destroying even resistant fungal forms such as the mutated fungi which result from antibiotic therapy.
Wild oregano is an oil rich plant. Each oregano leaf contains hundreds of oil glands. This oil is rich in a variety of natural compounds. The primary constituent of this oil is known as polyphenolic flavonoids. One of these, carvacrol, is a potent natural antiseptic. As discussed is Dr. Cass Ingram's "The Cure is in the Cupboard: How to Use Oregano for Better Health" oregano oil has been tested against a variety of microorganisms and is found to exert a high degree of anti-fungal, anti-parasitic, anti-viral and antibacterial actions.
