linseed

Linseed comes from the flax plant, especially its small seeds and the oil pressed from them. The oil is well known for use in oil paints, varnishes, and wood finishes because it dries and hardens in the air. The seeds have also been used as food and in animal feed. Today, people often say flaxseed when talking about food, while linseed is more common in art, industry, and older writing. It is a small part of the flax plant with a long and practical history.

Linseed refers to the dried, ripe seeds of the flax plant (Linum usitatissimum) or the oil extracted from them. While we often think of "flaxseed" as a health food today, "linseed" historically encompassed both the seed itself and, more commonly, the oil obtained from it. The word comes from the Latin linum, meaning flax, and the English word seed.

For centuries, linseed oil was prized for its drying properties, meaning it hardens when exposed to air. This made it valuable in oil paints, varnishes, and protective coatings for wood. It has long been used to bind pigments in painting, and you can still find "linseed oil" in art supply and hardware stores today.

However, linseed was never only about art. The seeds have also been used as food, especially in Europe and the Middle East, and they are still eaten today. In modern food contexts, the name "flaxseed" is often preferred, but it refers to the same plant. Linseed is also widely used in animal feed.

After the oil is extracted, the remaining material may be processed into linseed meal or cake, which has often been used as livestock feed or fertilizer. So, while you might see "flaxseed" on grocery store shelves, "linseed" usually carries a stronger connection to oil, painting, wood treatment, farming, and older usage.
