Burdock Root Tincture Burdock (Arctium spp.) is known as both an edible root and a useful medicine that assists liver function, digestion, and skin health. It is high in iron and a vast array of other minerals. Burdock tincture is typically made from either the fresh or dried roots. Here is what you need to do: Clean and cut up several fresh roots. Put them in a clean container (preferably glass) Use a vodka that has 50% alcohol content (also known as 100 proof) Add the alcohol at a 2:1 ratio (i.e. 2 cups of vodka to 1 cup of fresh roots) If you are using dried roots, use a 5 to 1 ratio instead (i.e. 5 cups of vodka to 1 cup of dried roots)
