Elixir
ELIX'IR, noun
1. In medicine, a compound tincture, extracted from two or more ingredients. A tincture is drawn from one ingredient; an elixir from several. But tincture is also applied to a composition of many ingredients. An elixir is a liquid medicine made by a strong infusion, where the ingredients are almost dissolved in the menstruum, and give it a thicker consistence than that of a tincture.
2. A liquor for transmuting metals into gold.
3. Quintessence; refined spirit.
4. Any cordial; that substance which invigorates.
