Osha has finally gained recognition as a major medicinal plant after a long history of use by Native Americans. An antibacterial expectorant and bronchiodilator, it is useful for cold/damp lung conditions. A mild antihistamine activity makes it useful for rhinitis, head colds and allergies. This aromatic root is also carminative, diaphoretic and emmenagogue.
