Native to the high elevations of the Rocky Mountains, Osha is a warming herb with a reputation for supporting the immune, respiratory, and digestive systems. Its primary action is on the gut-oral-lung axis, helping to clear dampness and promote healthy function across multiple body systems.

Osha, with its parsley-like appearance, is considered one of the best American herbs for respiratory and digestive support. Indigenous peoples of the Southwest and Mexico have long used the root to address a variety of respiratory issues, making it a staple in their traditional remedies.

As a warming herb, Osha stimulates circulation and supports the kidneys, lungs, digestive system, and uterus. It has been used both in traditional and Western medicine for immune health, particularly during seasonal challenges. The root can be chewed, consumed as a tea or tincture, burned for its clearing essential oils, or applied as a paste or ointment, depending on the area needing support.

Osha is also known as “bear root” in Native American culture, with a legend that brown bears, after eating the roots, would rub them on their fur. This led the Navajo (Diné) people to discover its powerful healing properties.
