Is flax an oilseed crop

Though not considered one of the major vegetable oils, flax is an important oilseed since it is the sole source of linseed oil. Linseed oil has been used for centuries as a paint and varnish additive to assist in drying. Flaxseed also provides a number of dietary and nutrition benefits as it is high in omega-3 oils, which helps the human cardiovascular system.
