What’s the history of goldenseal?
Goldenseal was historically used by the native Americans, specifically the Cherokees and Irioquios, for a huge variety of conditions. They used the plant as an insect repellent, diuretic, stimulant and to treat arrow wounds and other health problems. It grows wild in rich native deciduous forest in dense shade, and was named for the golden streaks it shows on when the stem is broken or damaged.
Goldenseal also has a reputation for holding the power of altering a urine sample given to check for drug use. A novel by pharmacist John Uri Lloyd where a urine sample’s outcome was altered by taking goldenseal led to the plant being used for that purpose… but it doesn’t appear to be effective.
What’s the best way to take goldenseal?
Berberine seems to be the substance within goldenseal that brings the health benefits but it’s not known how much is active when it is ingested in the form of goldenseal and as many supplements may contain very different amounts it makes it very difficult to say what will or will not be effective.
The root of goldenseal is sold dried and powdered in capsules, as well as other forms such as creams to apply to skin and also tinctures. Take around 4-6 grams per day in powdered form (within a tablet or capsule). If you are taking other forms of goldenseal, aim for 250-500mg three times a day.
