	[[Linseed oil]], also known as flaxseed oil, is a colorless to yellowish oil obtained from the dried, ripened seeds of the flax plant ([[Linum usitatissimum]]).

'''Linseed oil''', also known as '''flaxseed oil''', is a colorless to yellowish oil obtained from the dried, ripened seeds of the [[flax]] plant (''Linum usitatissimum''). The oil is obtained by pressing, sometimes followed by solvent extraction. Linseed oil is a drying oil, meaning it can polymerize into a solid form. Due to its polymer-forming properties, linseed oil is used as a [[carrier oil]] in oil paints, as a [[wood finish]], and in the production of [[linoleum]].

	== ~~History~~ ==		==Composition==
			Linseed oil is rich in [[alpha-linolenic acid]] (ALA), an [[omega-3 fatty acid]]. It also contains [[linoleic acid]], [[oleic acid]], and [[saturated fatty acids]]. The composition of linseed oil can vary depending on the growing conditions of the flax plant and the method of oil extraction.

	The use of linseed oil has been documented in various cultures, including those of Ancient Egypt, where it was used in the mummification process. In the Middle Ages, it was used in oil lamps and as a wood finish. It was also used as a base in paints, varnishes, and inks.		==Uses==

	== ~~Production~~ ==		===Industrial Uses===
			Linseed oil is widely used in the production of [[paints]] and [[varnishes]] due to its ability to form a tough, protective film. It is also used in the manufacture of [[linoleum flooring]], where it acts as a binder that holds the other materials together. Additionally, linseed oil is used in the production of [[oilcloth]] and as a preservative for [[wood]] and [[concrete]].

	~~Linseed~~ oil is ~~produced from the seeds~~ of ~~the flax plant. The seeds~~ are ~~harvested and cleaned before being pressed or solvent extracted to obtain the oil~~. ~~The oil~~ is ~~then refined~~ and ~~bottled for sale~~. ~~The production process can vary~~, ~~with some producers opting~~ for ~~cold pressing, which retains more of the oil's nutritional value~~.		===Nutritional Uses===
			As a dietary supplement, linseed oil is valued for its high content of omega-3 fatty acids, which are essential for human health. It is often consumed to support [[cardiovascular health]], reduce [[inflammation]], and improve [[skin health]]. However, it should be noted that linseed oil should not be used for cooking at high temperatures due to its low smoke point.

	== Uses ==		===Artistic Uses===
			In the art world, linseed oil is a key ingredient in [[oil painting]]. It is used as a medium to mix with [[pigments]] to create oil paints. The oil enhances the flow and gloss of the paint and allows for a longer working time, which is beneficial for artists.

	~~Linseed~~ oil ~~has~~ a ~~variety of uses~~, ~~both industrial~~ and ~~nutritional~~.		==Health Considerations==
			While linseed oil is beneficial in many ways, it should be consumed with caution. It can oxidize and become rancid if not stored properly, leading to the formation of harmful compounds. It is important to store linseed oil in a cool, dark place and to use it within its shelf life.

	==~~= Industrial Uses =~~==		==Processing==
			Linseed oil is extracted from flax seeds through a process of pressing and sometimes solvent extraction. The oil can be further processed to improve its drying properties, such as by boiling or adding chemical driers, resulting in what is known as "boiled linseed oil."

	In the industrial sector, linseed oil is used as an ingredient in paints, varnishes, and stains. It is also used in the production of linoleum flooring. Its ability to polymerize into a solid form makes it useful in the manufacture of oilcloth and in certain types of printing ink.		==Gallery==

	~~As a food supplement~~, linseed oil is valued for its high content of alpha-Linolenic acid. This omega-3 fatty acid is beneficial for heart health and can help to reduce inflammation. It is also used in vegan and vegetarian diets as a source of ~~omega-3 fatty acids.~~

	~~== Health Benefits ==~~

	~~Research has shown that~~ linseed oil may have several potential health benefits. These include reducing inflammation, improving heart health, and aiding in digestion. However, more research is needed to fully understand these potential benefits and the mechanisms behind them.

	~~== Safety and Side Effects ==~~

	~~While generally safe for consumption, linseed~~ oil ~~can cause side effects in some individuals, including diarrhea and allergic reactions~~. ~~It is also important to note that~~ linseed oil ~~should not be heated or used for cooking, as this can cause the oil to oxidize and become harmful.~~
