Medicinal Use of Osha

I was wondering how is osha used and what's in it? Also where and how does it grow?

Osha (Ligusticum porteri) is a plant much like the herb lovage. The root used medicinally to reduce mucus and relieve congestion, pain, coughing and wheezing in respiratory problems. It grows well in the south of the United States.
