Ligusticum porteri, known as Osha or oshá, is a perennial herb found in parts of the Rocky Mountains and northern Mexico, especially in the southwestern United States.
Its common names include osha root, Porter's lovage, Porter's licorice-root, lovage, wild lovage, Porter's wild lovage, loveroot, Porter's ligusticum, bear medicine, bear root, Colorado cough root, Indian root, Indian parsley, wild parsley, mountain ginseng, mountain carrot, nipo, empress of the dark forest, chuchupate, chuchupati, chuchupaste, chuchupatle, guariaca, hierba del cochino or yerba de cochino, raíz del cochino, and washí (tarahumara). In the Jicarilla language, osha is called ha’ich’idéé. The White Mountain Apache call it ha 'il chii' gah.
Osha is strictly a mountain plant, and it is most commonly found in deep, moist soils rich in organic material. The plant requires partial shade. Osha is widely distributed in the Rocky Mountains and the high mountains of northwestern Mexico. It is most common in the upper limits of the subalpine zone, so in the southern part of its range, it grows at elevations from 7,000 feet to 10,000 feet (2100 m to 3000 m), while in Utah and Wyoming, it grows as low as 5,000 feet (1500 m).
Osha is dependent on mycorrhizal fungi, and attempts to artificially cultivate the plant outside of its habitat have not been successful. Cultivation in areas where osha naturally grows have been more successful.
Osha has the typical appearance of members of the parsley family, with parsley-like leaves and umbels of white flowers. The bases of the leaves where they attach to the root crowns have a reddish tint which is unique, and the roots are fibrous, with a dark, chocolate-brown, wrinkled outer skin. When this skin is removed, the inner root tissue is fibrous and yellowish-white with an overpowering, pleasant "spicy celery" fragrance that resembles lovage (Levisticum officinale).
Osha roots have a collar of dead leaf material surrounding the root crowns which is hairlike in appearance. The roots dry very quickly and are very astringent when fresh, and can cause blistering of the mouth and mucous membranes in humans if ingested fresh. The dried roots do not have this astringent effect. Roots of older plants are far stronger and bitter than those of younger plants.
