Mushroom tinctures are a form of liquid extract that have been concentrated and are prepared from whole dried mushrooms. They are used orally as a supplement to help ward off a variety of health conditions or as a preventative measure to support particular aspects of your wellbeing.

Tinctures are liquid mixtures that contain both alcohol and water as the solvent. They each draw out the mushroom's vital elements to create a concentrated liquid. With this mixture, the mushroom's fruiting body is removed leaving you with just the beneficial compounds. 

The alcohol in the mixture also helps to preserve the contents for much longer use and is why these products are shelf stable.

Alcohol is considered to be the gold standard for a solvent used for producing tinctures. The use of alcohol has the added benefit of assisting these components in entering the bloodstream. Other liquids, such glycerin, vinegar, and honey, can also be employed as the solvent in place of alcohol. The resulting liquids are typically referred to as glycerites, vinegar, and oxymels, which is a honey vinegar mixture, rather than tinctures.

The word tincture, which was later changed to "tincture" in Middle English, comes from the Latin tinctus, which means moistened or dipped. By the 17th century, the word "tincture" had come to mean the colour of a medicine or herbal solution. This was because tinctures often take on the colour of the mushroom/plants they are extracted from. For instance, hibiscus flower tinctures are a rich purple colour. Cordyceps give the alcohol  a "Orange Crush" tint of orange.
