A tincture is typically an extract of plant or animal material dissolved in ethanol (ethyl alcohol). Solvent concentrations of 25–60% are common, but may run as high as 90%. [1] In chemistry, a tincture is a solution that has ethanol as its solvent.
There were many alchemists attempting to obtain the universal solvent, and thus many recipes, some later rejected by their creators, have been found. [8] Paracelsus's own recipe for alkahest was made of caustic lime, alcohol, and carbonate of potash; however, his recipe was not intended to be a "universal solvent". [9] [10]
Centrifugation is a process that uses an electric motor to spin a vessel of fluid at high speed to make heavier components settle to the bottom of the vessel. Evaporation removes volatile liquids from non-volatile solutes , which cannot be done through filtration due to the small size of the substances.

In chemistry, an alcohol (from Arabic al-kuḥl 'the kohl'), [2] is a type of organic compound that carries at least one hydroxyl (−OH) functional group bound to a saturated carbon atom. [ 3 ] [ 4 ] Alcohols range from the simple, like methanol and ethanol , to complex, like sugars and cholesterol .
Ethanol (also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound with the chemical formula CH 3 CH 2 OH. It is an alcohol, with its formula also written as C 2 H 5 OH, C 2 H 6 O or EtOH, where Et stands for ethyl. Ethanol is a volatile, flammable, colorless liquid with a characteristic wine-like ...

The American Chemical Society notes [citation needed] that the ideal organic solvents to use in a cooling bath have the following characteristics: Nontoxic vapors. Low viscosity. Nonflammability. Low volatility. Suitable freezing point. In some cases, a simple substitution can give nearly identical results while lowering risks.
