Osha root contains anti-viral, anti-bacterial, anti-fungal and anti-inflammatory properties and therefore supports health or healing for respiratory conditions (coughs, colds, tonsillitis, flu, and other types of viral infections). Its antiviral properties are well recognized today, and as an alternative medicine, it's often prescribed at the first signals of the common cold or flu. Osha can also be taken when traveling to higher altitudes or for long-distance hiking to promote easy breathing.
