Our aged tincture includes a balance of CBD and THC. Research and epidemiology are showing that the most effective cannabis medicine combines the two cannabinoids CBD and THC in a formulation to optimally treat the body condition. More research is probably forthcoming soon to explain why this is so. Until then, for cannabis medicine, it is recommended that at least a small percentage of THC is present in the formulation. Our tincture comes in various strengths. It is self-administered either by a couple of drops in water or drops placed directly under the tongue. The onset of effect of the cannabis medicine from a tincture is generally slower than vaping or smoking and faster than an edible, so about 20 minutes.
