Osha (Ligusticum porteri) is a plant that grows in Northern America. It has been traditionally used as medicine in Native American and Hispanic cultures.
Osha contains chemicals that might help fight bacterial and viral infections, and it has traditionally been used for these purposes. Be careful not to confuse osha with poisonous hemlock. The leaves of the two plants are very similar. Be sure to buy osha from a reputable source.
