Boiled linseed oil has been around for many years and is commonly used in woodworking and as a preservative for wood and other materials, but is it food safe? The short answer is yes, but it is important to note that boiled linseed oil should not be used in recipes or as a cooking oil. The reason why is because it contains a chemical called linoxyn, which can have adverse effects on humans if ingested in large amounts.
Boiled linseed oil is made by heating raw linseed oil to a high temperature and adding a drying agent, such as cobalt or manganese, to it. This process turns the oil into a thick, viscous liquid that is used as a preservative in many products and as a finish for woodworking projects. It is also used in some paints and varnishes.
The Benefits of Boiled Linseed Oil
Boiled linseed oil is a popular choice for wood finishing due to its ability to penetrate deep into the wood fibers, sealing them and preventing water damage. This makes it a great choice for outdoor furniture and other wood products that will be exposed to the elements. It can also be used to protect metal objects such as tools, and it can help preserve leather and other materials.
Boiled linseed oil is also known for its antiseptic properties, which make it a good option for treating minor cuts and scrapes. It has been used for years to treat skin irritations, and it is still used in some countries as an effective home remedy for skin ailments. It can also be used to help soothe and treat joint and muscle pain.
Is Boiled Linseed Oil Safe to Eat?
Although boiled linseed oil is not toxic, it should never be ingested or used in recipes as it can be dangerous if consumed in large amounts. The reason is that boiled linseed oil contains a chemical called linoxyn, which can be toxic if ingested in large amounts. It is important to note that linoxyn is not found in raw linseed oil, so it is safe to use in recipes as long as it is not boiled.
It is also important to note that boiling linseed oil will cause it to become more viscous, making it difficult to measure and use in recipes. Therefore, if you are using linseed oil in a recipe, it is best to use unboiled linseed oil. Additionally, it is important to note that when using linseed oil in recipes, it should always be used sparingly.

It is important to note that linseed oil should always be used in a well-ventilated area, as it can produce hazardous fumes when heated.
