What is a Tincture?
A tincture is a type of herbal preparation in which the alkaloids, glycosides, minerals, and essential oils of a plant are extracted into a solvent. The liquids that are most often used as solvents are high-proof alcohols such as vodka or brandy, or occasionally apple cider vinegar or even vegetable glycerin. The latter are sometimes used for children’s preparations, or by those who abstain from alcohol of any kind, but they’re not as effective at drawing the medicinal components from the plants.
In terms of efficiency, a single dose of a tincture has the same effect as a cup of herbal tea: it’s just concentrated, and absorbed more easily into your body via the alcohol (or other solvent). Some of these tinctures have medicinal properties, while others may have nutritional benefits.
