This should be cleaned up ! There are no wys 100 grams of oil can hold 20.0 grams of Protein !! May be the whole seed !! Would be nice to have more healh infos, also interesting that linseed oil is difficult to preserve (harder thatn other cold pressed oil! Because of Omega3 ? Sort of more like a fish oil ? Very interesting, looks possible to have the fishy oil benefit without the accumulation of toxic due to the higher position inside the food channel)
Agreed, that's absolutely ridiculous.  It should be something like 100% fat, and at 9kcal/g, a total of 900kcal/100g. Tom Huckstep 17:16, 12 April 2006 (UTC)

message: I believe that flax oil (aka linseed oil) is only a fire hazard (on oily rags etc.) if the metallic driers have been added.  Edible flax oil (such as Barleen's) presents no such hazard.  See

thread_title: As a fire hazard

message: I've put back the deleted commercial link to Polar Foods - actually replaced it with a more specific one. (I also replaced the second link that the same editor deleted, probably accidentally). The reason is that the oil discussed there is actually the subject of the footnoted text, and the link has more details on it. The fact that a site is commercial doesn't preclude it as a reference, if the purpose of the link is otherwise within WP policy. Waitak 21:00, 26 September 2007 (UTC)

thread_title:  Dubious health benefits 

message: ..Flaxseed oil has a higher rate of curing cancer than Chemotherapy..
The cancer claims are ridiculous and dangerous.
What on earth is the source of the nonsense about "Fire departments treat the wood handles of hand tools that have metal implements (e.g. axes, plaster hooks) with linseed oil to prevent buildup of static electricity"?  What a load of crap!  Fire departments, just like landscapers, farmers, carpenters and a multitude of other people who work with wooden-hafted tools use linseed oil as a wood preservative.  Nothing more.
I've excised this nonsense.  —Preceding unsigned comment added by 173.130.64.210 (talk) 16:13, 2 June 2009 (UTC)
thread_title:  Outrageous Claims 

message: In the section "Nutritional Supplement", the sentence "Plant breeders have developed flaxseed with higher alpha linoleic acid content (70%) and very low alpha linolenic acid content (< 3%)." has me confused.  I have never before encountered a reference to "alpha linoleic acid", and can't imagine anyone seeking to minimize "alpha linolenic acid content".  RCopple (talk) 16:56, 1 September 2009 (UTC)
thread_title:  Linoleic <=> Linolenic Confusion? 

message: There seems to be dispute going on about whether modern (no-lead) driers, such as those being added to boiled linseed oil, are food-safe. Does anyone have any definitive source for this? Rumiton (talk) 14:50, 8 November 2009 (UTC)
replies: text: Boiled linseed oil is not food-safe. It will polymerize without catalysts like lead. The point of boiling it is to begin the polymerization with oxidation. A lot of interesting things are in this review, and it's not what I am looking for in a repudiation of a line that claims flax is stable at baking temperatures. This is:  I do not understand why it's not in Pub Med, and it looks like an abstract. linseed <> flaxseed -- One is for paint. The other is nutritional. One is heated and oxidized. The other has been carefully kept away from oxygen and cold-pressed. 75.152.125.56 (talk) 02:51, 30 January 2013 (UTC)
thread_title:  Metallic driers food-safe? 

message: "Oiled wood may be yellowish and is likely to darken with age." Can someone explain this further.  To me, wood coated in linseed oil has a much more pleasing and natural looking finish than that treated with varnish.  However this yellowing, which I have noticed with pine, can spoil the look of the wood.  I assume that non-natural oils do not cause yellowing, but it does seem a shame to oil natural wood with man-made chemicals.  — Preceding unsigned comment added by 62.56.111.181 (talk) 02:57, 26 February 2012 (UTC)

thread_title:  Photo is of flaxseed oil, not linseed oil 

message: While Linseed Oil and Flaxseed oil come from the same source Flaxseed oil is cold pressed and raw food grade oil while Linseed Oil is a treated substance that is sold in hardware stores and is NOT safe to consume. Linseed oil is used in paint, rust remover and finishers. Linseed Oil is not Flaxseed Oil as is stated in the first paragraph. This is dangerous as the article moves from discussion of industrial uses of Linseed oil to the health benefits of Flaxseed oil without any discussion of the difference between the two substances. Repoman23 (talk) 17:34, 28 May 2012 (UTC)
replies: text: Seems that you might be on to something but we need a good book that discusses the possible distinction between flaxseed and linseed oils.  I will say that just because linseed oil is used for all sorts of apps does not mean that it is unfit for human consumption.  Please look for a book that discusses the point that interests you - my source {Ullmanns Encyclopedia) says that they are the same.--Smokefoot (talk) 00:43, 23 July 2012 (UTC)

text: I am unsure how digestible boiled linseed oil is, but I doubt that it is particularly toxic.  If someone ate linseed oil that they had bought at a hardware store, we could not reasonably be expected to stop that kind of dumb behavior.  There is a section near the end of our article on "Boiled linseed oil" and reading that makes it pretty clear that it is not intended for consumption.  But Wikipedia-Chem does not add warnings about not eating chemicals.  Thanks for your help, but I dont think that we have a problem.  I still would be interested in finding a source that distinguishes flaxseed and linseed oils.--Smokefoot (talk) 03:02, 29 July 2012 (UTC)
replies: text: Hello. I run a workshop producing food grade utensils: barbecues, smokers etc., and I am afraid you are not correct regarding toxicity. Boiled linseed oil used to be just that, but for the past 30 years thinning and drying agents have been added which make it highly toxic, not just inedible, but unusable in any cooking environment. See this ad  as an example. Rumiton (talk) 04:02, 29 July 2012 (UTC)

text: Most household and industrial products come with a MSDS, or one can be obtained from the manufacturer. Basically, if it doesn't say OK for human consumption or food preparation, don't do it. Rumiton (talk) 13:44, 23 December 2012 (UTC)
thread_title:  Article Intro Implies Linseed Oil is Food Safe 

message: It is incorrect to view the two oils as being different.
The following sentence in the article does not make sense: "Linseed oil and flaxseed oil are both derived from the same plant, but oils may differ because of the way they are processed."
The processing method for obtaining an oil does not change its name!
62.195.45.181 (talk) 09:36, 6 February 2014 (UTC)
replies: text: The processing method, and the implicit market, certainly does change the name. Imagine trying to sell, "Healthy Oil, just like they use in Paint"! For another obvious example, linseed and boiled linseed. Andy Dingley (talk) 11:47, 6 February 2014 (UTC)
thread_title:  Linseed oil = flaxseed oil 

message: The Stand Oil reference is publically inaccessible and there is no reference for boiled linseed oil. Linseed and other polyunsaturated oils were boiled with Litharge (Lead Oxide)http://books.google.com/books?id=C-uiAK74XpsC&pg=PR239&lpg=PR239&dq=boiled+linseed+oil+litharge&source=bl&ots=XJfIX8dSs_&sig=SW-ao9-vvLAmULQEjByzTToWWTY&hl=en&sa=X&ei=RrHOU5OlLIGBiwK0mIH4Cw&ved=0CEgQ6AEwCA#v=onepage&q=boiled%20linseed%20oil%20litharge&f=false which speeds drying by catalytically promoting oil reaction with atmospheric Oxygen. I can find no public references that describe dies alder reaction in paint drying. Initial hardening of linseed and other drying oils is due to formation of Peroxide links between two different oil molecules. Peroxides are unstable and responsible for the spontaneous flammability of "oily rags" mentioned in below paragraphs. If the author does not correct those sections I will delete them.

replies: text: Ullmann's Enclyclopdia, virtually the bible of chemical technology, explains the situation well.  Yes, access requires payment, but that is the way it is for good sources, unfortunately.  I reversed the order of the presentatoin since I think most readers want to see how "boiled" oil is used in modern times before getting to the Medieval use.  But I would be glad to cooperate on this topic, which interests me.--Smokefoot (talk) 01:15, 23 July 2014 (UTC)
thread_title:  Invalid reference and made up information about Linseed oil chemistry. 

message: Greetings! At the moment, the article says the following (emphasis added):
Seymour & Danin (1987), however, state that:
This would suggest the exact opposite. If one runs a Google search with keywords: "linseed oil" "slow oxidation", one will run into a whole lot of sources that discuss the same. As far as I am concerned, this is a very typical topic in the field of painting. By that simple search, I was able to found a couple of other sources, although rather old, that discuss the slow oxidation of linseed oil
