Tincture of cannabis, sometimes known as green dragon, is an alcoholic solution of cannabis.


The tincture is typically made from soaking the flowers, leaves, or stems of the Cannabis plant in ethanol. The tetrahydrocannabinol (THC) and other cannabinoids dissolve into the alcohol. Some preparations also extract some of the water-based plant products such as chlorophyll, resulting in a dark green or brown liquid. Baking or "drying" the cannabis to decarboxylate prior to the alcohol bath increases the potency of the THC in the resulting preparation.[1][2]

Methods of use[edit]

The tincture is ordinarily consumed orally, but may also be applied to the skin.

A similar preparation called nabiximols (USAN,[3] trade name "Sativex") is a pharmaceutical preparation for administration as an oral spray.
