Tincture of Cannabis (Wikipedia)
Tincture of cannabis, sometimes known as green dragon, is an alcoholic cannabis concentrate. The solubility of THC in ethanol is greater than 1 g/mL.
According to the European Medicines Agency (EMA) cannabis tinctures (tincturea) are a type of liquid cannabis extract obtained using ethanol, water, glycerol, propylene glycol and fatty oils as extraction solvents, depending on the type of tincture (and also on the solvent used) it can have a specific mass/volume ratio or a specific therapeutic agents content.
Cannabis tinctures are used in the production of specific extracts, like nabiximols.
