Search for an osha root tincture recipe and most of what comes back is product listings with a ratio buried in the small print. The recipe herbalists work from is short. Dried osha root (Ligusticum porteri) goes into strong alcohol at a set weight to volume, sits for weeks, and is pressed out. The numbers below come from the late herbalist Michael Moore, who spent decades with this plant in the mountains of New Mexico and Northern Mexico. After the numbers comes the part the recipe pages skip, which is where the root itself comes from.
What goes into an osha root tincture recipe
Michael Moore ran the Southwest School of Botanical Medicine and published his working tincture formulas in Herbal Tinctures in Clinical Practice (version 3.0, 1996). His entry for osha lists two preparations:
- fresh root at 1:2
- dried root at 1:5, in 70% alcohol
Most osha sold as loose root is dried, so 1:5 is the ratio people end up asking about.
Osha tincture ratio, in plain numbers
A ratio of 1:5 means one part root by weight to five parts liquid by volume. In practice that is 100 g of dried root to 500 ml of liquid. The 70% figure is the alcohol strength of that liquid, which is far stronger than a bottle of vodka at 40%. Osha's flavor and aroma sit in its oils and resins, and those dissolve into strong alcohol far more readily than into water.
The fresh root ratio is tighter (1:2) because fresh root already carries its own water, which dilutes the alcohol as it steeps.
How long a homemade osha tincture takes
Weeks. Finnish herbalist Henriette Kress, whose tincture notes have been passed around herb forums since 2000, gives 2 to 4 weeks of steeping in a cool, shady spot for dried herbs, with the root crushed rather than powdered. Moore preferred percolation for dried roots, where the alcohol drips slowly through a packed column of ground root, and treated soaking in a jar as an accepted second choice.
Either way, the liquid then has to be strained and pressed, and the root left behind holds back a share of it. A jar started today is a bottle about a month from now.
Osha stopped more than half the growth of the TB bacterium at the lowest concentration tested.
Families soaked this root in alcohol long before it had a recipe
Osha has many names, and each one comes with a household tradition. Hispanic ranchers in New Mexico call it chuchupate (Dodson and Dunmire, 2007). Writer Estevan Arellano recalled in 2012 that his mother made sure the family had oshá root with them whenever they went up the mountain for firewood. In Mexican records gathered by Zárate Cruz, alcohol extracts of the root sit alongside teas and poultices as a home preparation, and the Rarámuri of the Sierra Madre brewed the root as a tea for stomach pain and fever.
The Lakota name, mato tapejuta, means bear medicine. The story behind it is that bears dig up the root when they wake from hibernation and chew it, and observer Shawn Sigstedt watched Kodiak bears chew osha and rub it into their fur.
The hard part is the root
A tincture is only as good as the root that went into it, and osha is one of the hardest roots to buy well.
Nobody has managed to farm it at scale. Kelly Kindscher and colleagues at the University of Kansas wrote in 2017 (Natural Areas Journal) that cultivation has not been economically viable, so almost all osha on the market is dug from the wild, an estimated 1,000 to 2,000 kg of dried root a year. The plant grows slowly, and the roots sold are often from plants more than 10 years old. United Plant Savers lists osha as At-Risk and notes informal reports of wild stands of 100 plants or fewer disappearing after heavy digging.
Then there is identification. Osha grows at roughly 1,000 to 3,500 m, and where its range overlaps with poison hemlock (Conium maculatum) the two look alike above ground. Moore warned of the confusion in 1979, and the University of Kansas native plants program says telling them apart takes a close look at the seeds and roots, including the smell of the root. Poison hemlock is deadly, so foraging your own root for a homemade osha tincture is a bad bet for anyone who is not already an expert.
Buying dried root online brings its own problems. A bag of chopped root often says nothing about species, where it was dug or when. The aroma also fades. Osha's signature compound is Z-ligustilide, and a 2007 team at the University of Illinois at Chicago (Schinkovitz and colleagues, Planta Medica) found that the pure compound broke down within 24 hours once dried, while it held up in solution. Root that sits in a bag for months loses the very oils a tincture is made to capture.
Bear Root – Osha Root Tincture
50 ml dropper bottle. Ligusticum porteri from the mountains of Northern Mexico.
Add to bagWhy most people buy it made
Bear Root is osha root tincture made from Ligusticum porteri, a mountain plant of Northern Mexico. The root has already been extracted, strained and bottled, so there is no month of waiting and no guessing what was in the bag. Simple ingredients: premium quality extract.
It comes in a 50 ml dark Miron glass dropper bottle. If you are comparing bottles, dark amber glass is a step in the right direction, and dark Miron glass is the gold standard because it keeps light off the extract. At 1 to 2 droppers a day, one bottle lasts 30 to 50 days.
The taste is earthy and warming, with the sharp, celery-like bite of the root. People use it in a few ways through the day:
- under the tongue in the morning, held for 20 to 30 seconds, then swallowed
- stirred into a mug of tea
- a dropper in the water bottle after a hike or a run
- in juice or a smoothie
It fits any time of year, and the bottle fits in a gym bag. For more on the plant itself, the full guide to osha root covers its range, names and history.
Bear Root considerations
Contains alcohol. Not recommended during pregnancy. If you're nursing or taking medication, ask your doctor before using it.
Questions people ask
What is the ratio for osha root tincture?
Michael Moore's published formula is 1:5 for dried root in 70% alcohol, and 1:2 for fresh root. For dried root that works out to 100 g of root per 500 ml of liquid.
How long does osha tincture take to make?
Herbalists give 2 to 4 weeks of steeping for dried root, then straining and pressing. A finished extract like Bear Root is ready the day it arrives.
What does osha tincture taste like?
Earthy and warming, with a sharp bite close to celery. Moore described the smell of the root as butterscotch and celery.
Can I use vodka instead of 70% alcohol?
Standard vodka is 40% alcohol, well below the 70% in Moore's formula. Osha's oils and resins need the stronger alcohol to come out of the root, which is one reason most people buy osha tincture already made.
