tinctures

A tincture is a concentrated liquid extract produced by macerating plant material or other substances in a solvent, typically ethanol. The term comes from Latin tinctura, meaning a dye or coloring matter, reflecting its historical use as a colored extract. In modern practice, tinctures may also be made with glycerin or a mixture of water and alcohol (hydroalcoholic) to create glycerites or other non-alcoholic preparations.

Preparation and composition: Plant material is soaked in a solvent that dissolves the desired constituents, allowing them to diffuse into the liquid. The mixture is then strained to remove solids. Percolation is another method used to extract compounds. Ethanol is effective at extracting a broad range of plant components, including both polar and nonpolar substances; glycerin-based tinctures are used when alcohol is unsuitable. The final product is a highly concentrated liquid that retains flavor, aroma, and pharmacologically active components.

Strength and dosing: Tinctures are often described by a ratio that expresses the amount of plant material to the final product, such as 1:5 or 1:2, indicating the potency and preparation method. Dosing typically uses a dropper and depends on the specific tincture, the plant material, and the intended use. Older and regulatory traditions may specify standardized strengths, though potency can vary with harvest, processing, and storage.

Uses and considerations: Tinctures are widely used in herbal medicine for oral administration or, less commonly, topical use. They have a long shelf life when stored in tightly sealed, dark bottles. Safety considerations include alcohol content, potential interactions with medications, and variability in quality. In many regions, commercially produced tinctures are regulated as herbal products or dietary supplements, with quality control and labeling standards.
