oleoresin
Quick Summary
An oleoresin is a natural plant product that contains both essential oils and resin. It can also refer to a preparation where oil holds resin in solution. These substances are often found in plants and can be obtained from living trees, such as the fluid that exudes from pine trees when cut, which is the raw material for gum naval stores. Oleoresins can also be derived from deadwood. The term "oleoresinous" describes something related to or containing oleoresin, or something made from drying oils and resins, often used for varnishes or paint vehicles. Essential oils themselves are volatile substances from plants, and their presence in a plant might serve protective functions, like sealing wounds against parasites.1234
