🌱 What it is
Osha (Ligusticum porteri) is a wild root native to the high Rocky Mountains, traditionally chewed, made into tea, or tinctured for chest and throat complaints.
📜 Where it comes from
Osha root has long been gathered from the high slopes of the Rocky Mountains by Native American peoples, including the Navajo and other Southwestern tribes, who chewed the root or brewed it for coughs, sore throats, and respiratory complaints. Frontier and folk herbalists of the American West adopted the practice from these Native traditions. It remains a favorite in Western herbal medicine today, though wild populations are harvested carefully due to slow growth.

⚠️ Cautions
- Wild osha is frequently misidentified with poisonous look-alikes such as poison hemlock and water hemlock — buy only from a reputable, correctly identified source, and never forage it yourself unless expertly trained
- Osha is slow-growing and at risk in the wild; overharvesting is a real concern, so look for cultivated or ethically wildcrafted sources
- Avoid in pregnancy; traditional sources caution against use due to possible uterine-stimulant effects
- Not intended for long-term daily use
- A cough with high fever, chest pain, or breathing difficulty needs a doctor — this supports comfort, it does not treat infection.
