Wise Woman Herbals’ Osha (Ligusticum porteri) has been used for centuries to support the immune and respiratory systems. It is also known as Ligusticum porteri, which means “root of the mountain spirit.”

Osha is believed to work by releasing the exterior, dispelling wind cold, tonifying the lungs, tonifying the spleen, invigorating the blood, and promoting urination. The exterior is the outermost layer of the body, and wind cold is a type of external pathogen that can cause colds, flu, and other respiratory problems. The lungs are responsible for breathing, and the spleen is responsible for digestion and absorption. The blood is the body’s fluid that carries nutrients and oxygen to the cells.
