Osha root (Ligusticum porteri) has a long history of use in traditional Native American and Hispanic herbal medicine, particularly for respiratory and sinus health. Indigenous peoples and herbalists have used osha root as a remedy for coughs, colds, sore throats, and sinus congestion. The traditional rationale is that osha root contains volatile oils and other constituents that are thought to help open airways and reduce inflammation or infection in the respiratory tract, including the sinuses. The root is often chewed or brewed into teas for this purpose.

However, there is limited scientific research specifically validating the efficacy of osha root for sinus health. Most evidence for its use is anecdotal or comes from ethnobotanical sources. Some laboratory studies have identified antimicrobial and anti-inflammatory properties in extracts of osha root, but these findings have not been robustly tested in human clinical trials, particularly for sinus issues. As such, while osha root is widely used in traditional medicine for supporting the sinuses, the evidence supporting its effectiveness is not strong by modern scientific standards.

In summary, the use of osha root for supporting sinus health is justified by tradition rather than robust scientific validation.
