Linseed oil is a natural oil derived from the seeds of the flax plant. It is commonly used in various applications, including as a drying agent in paints and varnishes, as well as a wood finish. The oil is rich in omega-3 fatty acids, making it a popular dietary supplement for promoting heart health. In addition to its uses in art and health, linseed oil is also utilized in the production of linoleum flooring and as a binder in oil paints. Its ability to harden when exposed to air makes it valuable in both industrial and artistic settings.
