Tinctures are liquid extracts that are derived from herbs. This product is a double extraction with water and grain alcohol in order to provide the maximum constituents. The easy to use tincture can be taken orally. Use it as a mouthwash before swallowing. As a tincture, the extract will enter the bloodstream more directly which means that its effects will be faster. Consuming it is convenient. All you have to do is take a drop of the tincture and you are done. Take 15 to 20 drops daily. The bulb determines the amount of liquid in the tube and not the length of the tube itself.
