Rosin extraction is a solventless method for concentrating essential oils from plant material using heat and pressure. The process yields a resinous substance rich in desired compounds. This technique offers a straightforward approach to obtaining a potent extract.
The advantages of this extraction method include its simplicity, safety, and absence of potentially harmful solvents. It allows for the creation of a purer, cleaner product. Historically, mechanical pressing has been used in various industries, with this application emerging more recently in the botanical extract field.
