Linseed oil, also known as flaxseed oil, is a natural oil extracted from the seeds of the flax plant (Linum usitatissimum). It is commonly used as a drying oil in wood finishing, paints, and varnishes due to its ability to harden upon exposure to air. Linseed oil is also used in nutritional supplements, animal feed, and as a binder in linoleum flooring. It has a golden-yellow color and a distinctive earthy odor.
