Oil of oregano could win an award for being one of the most effective natural treatments for the common cold and flu. (And by the way, this oregano is not the same species as the one you put in your pasta sauce.)
The oil is made from the leaves and flowers of wild oregano (Origanum vulgare), a hardy, bushy plant that’s a member of the mint family. One reason oil of oregano is considered a health-giving hero is that it contains the chemical carvacrol, which has demonstrated illness-fighting abilities: It is antibacterial, antivirus, antifungus, antitumor, anti-inflammation, and antiparasitic.
