Tincture of cannabis

[1] 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.

[3] In the 20th century cannabis lost its appeal as a medicinal product, largely due to the development of apparently suitable alternatives, such as the hypodermic needle, water-soluble analgesics and synthetic hypnotics.

The tincture is typically made by soaking the dried flowers of the female hemp plant (marijuana) in ethanol.

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 amount of THC in the resulting preparation.
