Stone root (Collinsonia canadensis), a perennial plant native to North America, has a long history in herbalism. Traditional herbalists turn to it for urinary tract comfort and to ease occasional digestive upset.
You can take it as a tincture, tea, or capsule. Dosage depends on the form and why you are using it. Without modern clinical trials, there is no standard dose.
Pregnant or breastfeeding women should avoid stone root because safety data is missing. Talk to your doctor before taking any supplement, especially if you have a health condition or take medications.
