Burdock root is generally taken as an herbal tea three to five times per day.
German authorities recommend using 2.5g of finely chopped or coarsely powdered drug per cup of tea (1 teaspoon of powdered burdock root weighs approximately 2 grams).
Remember, as with many herbal teas, burdock root tea is diuretic, so don’t over-consume.
It is recommended that the tea be infused in cold water first (for up to several hours) and then boiled for up to an hour and finally passed through a strainer. This long process serves to increase the bioavailability of some of the active ingredients. As a food, this root can also be added to soups
Besides, Traditional herbalists recommend 2-4 ml of burdock root tincture per day.
