It is simple decide how much you want to make of a tincture and center herbs would be 2 parts, connectors 1 part and point herbs 1/2 part. So if that was fluid ounces, 2 oz, 1 oz and 1/2 oz, total 10.5 oz. If you are using dry herbs for a tea, I do 3 tbsp for each of the center herbs, 2 tbsp for connectors, 1 tbsp for the point herbs and then grind/blend them, that makes about 1 months supply.
