Tinctures are made, nearly always in ethanol, by steeping a material in the solvent, usually for long periods of time.
By convention the percentage concentration of a tincture is derived from the proportion of solid material to solvent at the start of the process and does not represent the proportion of material left in the tincture after filtration.
