HEMP OIL != HEMP SEED OIL

this article seems to only deal with HEMP SEED OIL... which is not HEMP OIL —Preceding unsigned comment added by 90.194.64.11 (talk) 13:39, 7 June 2008 (UTC)

Perhaps the unsigned author is correct, that "hemp oil" is not "hempseed oil". In any event, I would also support this suggestion that this article heading be changed to "hempseed oil", with that spelling, to avoid any confusion with the drug-Cannabis product that is unfortunately being promoted as "hemp oil". The term "hemp" should be reserved to describe industrial uses of non-drug Cannabis. The product promoted as "hemp oil" apparently seems to be made from drug-Cannabis, not hemp.(Jace1 (talk) 16:01, 21 August 2008 (UTC))

I agree, and since there's been no activity on this thread since August, I'm going to change the article's name.--DoctorSlaw (talk) 06:33, 31 March 2009 (UTC)

This change appears to have been reverted, and it is causing references in other articles to hempseed oil to be misleading. If we are going to state that hempseed oil is not hemp oil, we ought not inter-change them like this. They are completely different substances! 94.196.92.199 (talk) 23:53, 14 March 2010 (UTC)

80%?

I'm very confused by the line "30–35% of the weight of hempseed is oil containing 80% essential fatty acids (EFAs)" Is it trying to say that 80% of the 30-35% of the weight of hempseed oil is EFAs, or that 80% of the weight is EFAs, or something else? I looked on the reference that did work of the two and from what I understood 80% of it was EFAs, but I'm not sure because I am not an expert or familiar with this subject. I would like to know where the 30-35% came from, because it does say earlier on in this article that 30-35% of the seed was oil by weight. I would change it but I don't know if I'm correct in saying it needs to be changed. Thanks 24.116.241.14 (talk) 03:42, 30 June 2008 (UTC)

Maybe I can help. If so, then let's work together to clear this up so that anyone might be able to understand it (the unsigned user above does seem to have this right, but is not sure). The total oil content of the hemp seed is typically between 30-35%. Of the oil, about 80% consists of the two EFAs (linoleic acid and alpha-linolenic acid- the protypical omega-6 and omega-3 respectively). Again, this 80% only considers the oil part of the seed. In other words, 80% of the 30-35%. Does this help?(Jace1 (talk) 15:27, 21 August 2008 (UTC))

Hempseed oil is a "food", and may also be considered as a functional food because of its high content of essential fatty acids (EFAs), and apparently has the ability to clear up some common health problems. See references under "Citations" for examples of evidence to support the claim that hempseed oil is a functional food. Hempseed oil is a liquid, so I guess it could be considered as a "drink", but this use would be atypical. Overall, it seems to me that the food and drink tag applies to this topic.(Jace1 (talk) 15:32, 21 August 2008 (UTC))

Citations

The link for "Hemp seed oil: A source of valuable essential fatty acids" goes no where. I can suggest the following article (full disclosure: I am the author of this article):

Callaway JC (2004). Hempseed as a nutritional resource: an overview. Euphytica 140: 65-72.

The PDF can be downloaded from www.finola.com for free (full disclosure: I have a commercial interest in this web site). The article was published in a respected peer-reviewed journal, so I'm not concerned about the potential conflict of interest or putative lack of neutrality for this information. However, I am not entirely comfortable in taking the responsibility of drawing attention to the Finola website on the "Hemp Oil" article page to provide a link to this PDF. Could someone with more experience/objectivity offer some guidance here?

Also, two more articles that are worth mention. These are the only two publications that currently exist on clinical studies of hempseed oil (full disclosure, again: I am first author on one of the articles and co-author on the other):

This article supports the anecdotal reports of regular dietary hempseed oil clearing up symptoms of atopic dermatitis (eczema), and is another free download as a PDF from www.finola.com:

Callaway, JC, Schwab U, Harvimaa I, Halonen P, Mykkänen O, Hyvönen P & Järvinen T (2005). Efficacy of dietary hempseed oil in patients with atopic dermatitis. Journal of Dermatological Treatment 16: 87-94.

This other article involved healthy volunteers that had no particular health problems, yet we did see an improvement in the total-to-HDL cholesterol ratio after the hempseed oil but not after the flaxseed oil intervention. Also, hempseed oil increased all blood lipid profiles of gamma-linolenic acid (GLA), which is good, while flaxseed oil decreased blood lipid profiles of GLA. The publisher of this article does not allow posting the PDF on a commercial website, so the interested reader will have to dig it up from the library, but here is the reference:

Schwab U, Callaway J, Erkkilä A, Gynther J, Uusitupa M, Järvinen T (2006). Effects of hempseed and flaxseed oils on the profile of serum lipids, serum total and lipoprotein lipid concentrations and haemostatic. European Journal of Nutrition 45(8):470-7.

I'll wait a bit for comments before I post these three references on the "Hemp Oil" page.(Jace1 (talk) 15:55, 21 August 2008 (UTC))

OK, I've done some basic work on this. Unfortunately, I deleted a general reference by Gero Leson on hempseed nutrition. This was a short, two page overview from 2002/2003 that was part of the vote hemp report project. If someone would like to repost that, I'll have no objection, but I am unable to find that reference and the newer references cover the same info in more detail.Jace1 (talk) 23:29, 14 November 2008 (UTC)

Merge into main article?

Does this article contain any information that isn't already in the main article? --SV Resolution(Talk) 14:45, 20 March 2009 (UTC)

I would say that considering the various uses and potential for strong interest in this subject, together with the precedent set by articles concerning other plants and their edible oils (i.e. corn/corn oil), a separate article is probably warranted. --DoctorSlaw (talk) 06:21, 31 March 2009 (UTC)

I fully agree. There are many relevant discussions on various aspect of the plant Cannabis sativa L.; e.g., drug Cannabis (medicinal and/or recreational), non-drug Cannabis (hemp: food from the seed, fiber from the stalk, etc.). There seems to be no clear cutoff for it, and certainly not one many will agree upon, and any of these topics can potentially go much further than a stub.Jace1 (talk) 12:05, 17 April 2009 (UTC)

I use hemp oil. It's wonderful, but it has, I'm sad to say, no hallucinogenic nor euphoric side effects! (You can bet if it did it'd be illegal.) Anyway, it's great to cook popcorn with. I also use it to grease the sheet pan for pizza cooking and I add a teaspoon to pasta dinners. It makes everything taste great, but the big drawback is that it's expensive: costs about a buck an ounce. Ouch! —Preceding unsigned comment added by 169.133.253.21 (talk) 01:41, 17 March 2010 (UTC)

Omega-6/Omega-3 ratio

I have not been able to find a hemp-neutral source to support that 3-1 is the optimal ratio. Also, since Omega-6 is found in corn and soy oils, the average diet already has a very high ratio (15-1). Adding hempseed oil at 3-1 will not be as effective at reducing the ratio as flax or fish oils. Omega-6 deficiency is possible, but unlikely.

http://www.ncbi.nlm.nih.gov/pubmed/12442909 http://www.vimeo.com/17767942 —Preceding unsigned comment added by 72.177.2.129 (talk) 17:46, 17 March 2011 (UTC)

In fact, the "optimal" 3:1 ratio was proposed well before hempseed oil entered the market in the late 1990s. Published scientific studies on hempseed oil were actually lacking until quite recently. The 2002 reference cited in the web link above is a very good citation for this topic. As for the assertion offered in the first comment on the biological effectiveness of hempseed oil; not true! Clinical studies have already shown that modest amounts of hempseed oil do have highly significant impacts on altering omega-6/3 blood profiles in humans. For example, see cited references 5 (Schwab et al. 2006) and 7 (Callaway et al. 2005) in the article. On the last point, the unsigned comment is correct; omega-6 deficiency is highly unlikely, and perhaps not even possible in a realistic sense. The physical intake of omega-6/3 is important, but also consider the enzymatic activity of delta-6-desaturase in vivo. Also worth noting is the present of both SDA (omega-3) and GLA (omega-6) in hempseed oil. These super unsaturated fatty acids are also the same physiological products of the two "essential" fatty acids; linolenic acid (omega-3), which is converted in the body to SDA and linoleic acid (omega-6), which is converted in the body to GLA. Neither SDA nor GLA are found together in other commercial food oils. By adding SDA and GLA directly to the diet, we can influence the rate limiting activity of delta-6-desaturase. This may explain why beneficial effects are so easily noticed after using hempseed oil for only a few weeks, especially in people who suffer from skin problems that are linked to poor delta-6-desaturase activity (like eczema).

Naming hemp oil with THC

The following sentence makes little sense, since it advises us not to do what the sentence actually does do: "Marijuana Hemp oil containing psychoactive cannabinoids should never be referred to as 'hemp oil', as the modern usage of the word 'hemp' is reserved for plants that meet the legal requirement of containing 0.3% THC or less." Either drop this sentence or provide an alternative phrase for hemp oil containing THC. Burressd (talk) 21:19, 23 March 2011 (UTC)

Burressd is correct! Moreover, the phrase "marijuana hemp oil" is both illogical and redundant by the juxtaposition of "marijuana" and "hemp". Why not use "hempseed oil" or even "hemp seed oil" for the non-drug food product, and "marijuana oil" for the drug product? Jace1 (talk) 11:30, 27 March 2011 (UTC)
