Herb of the Day: Osha
Posted by TriLight Health on Sep 24th 2026
In the heights of the Rocky Mountains, you'll find a unique herb. This herb is only found in a handful of other high-elevation locations. Many Indigenous tribes consider it sacred, and it has an extensive history of use. Osha, or Ligusticum porteri, is this rare and prized herb. Indigenous peoples used this herb for food, cleansing, clothing, and medicine. It has a wide range of culinary uses and a unique flavor somewhat like celery + licorice. Most commonly used for respiratory concerns, Osha is valued for other applications as well.
Traditional Uses of Osha:
- Allergies
- Cold
- Digestion
- Flu
- Inflammation
- Respiratory support
- Sore throat
Topical use can also be beneficial, usually on cuts and wounds. This used to be a rarely used herb, but its use is becoming more widespread among herbalists. Osha seems to be in a class among itself for a number of reasons. Two other unique facts about herbal use of Osha are that it is sometimes chewed for medicinal benefit and sometimes burned.
