Tincture

A tincture is typically an alcoholic extract of plant or animal material or solution of such or of a low volatility substance (such as iodine and mercurochrome). To qualify as an alcoholic tincture, the extract should have an ethanol percentage of at least 40-60% or 80-120 proof. Sometimes even a 90% or 180 proof tincture is achieved. In herbal medicine, alcoholic tinctures are made with various concentrations of ethanol, 25% being the most common. Other concentrations include 45% and 90%.
