Article development plans[edit]

Added external links to some relevant, current, and peer reviewed cancer research.

Added long list of references regarding olive leaf (extract) research, but would be good if others could add some links to these references.

Also added the homepages of doctors Walker and Ritchason N.D., as they seem to be the main points of reference for most of the main "Olive Leaf (extract)" article.

Broke the article down into subsections, and also cleaned up some, but not all, of the copy, especially in regard to expression.

The last section on precautions is posted from the Olive Leaf Extract Advanced Health & Life Extension article, so if there's someone who knows how to link references could you please do so.


This article leaves much to be desired. There is much content that appears anecdotal; some of which appears to be just simple generic fallacy. To wit; The first sentence:

"Olive leaf is the leaf of the olive tree (Olea europaea). While olive oil is well known for its flavor and health benefits, the leaf has been used medicinally in various times and places." Really, well known to who? I read a reference from some piece that refereed to; "Blah blah was used by Hippocrates for a remedy of blah blah" Citing unverifiable authorities may work in politics but has no relevancy in research, or journaling research.

"Natural olive leaf and olive leaf extracts (OLE), are now marketed as an anti-aging, immunostimulator and an antibiotic. " Again so what, snake oil has also been marketed for ages.

"Clinical evidence has proven the blood pressure lowering effects of carefully extracted olive leaf extracts.[1][2][3][4]" citing the first 4 ref. None of who have any initials after their name. Perhaps they are so well known they and there research does not need to be cited properly?

"Bioassays support its antibacterial, antifungal, and anti-inflammatory effects at a laboratory level. A liquid extract made directly from fresh olive leaves recently gained international attention when it was shown to have an antioxidant capacity almost double green tea extract and 400% higher than vitamin C.[5] For a university; SCU; that has no Biology dept. or Medical school this does not impress me that much. Especially when I reviewed the universities publications and was unable to verify this supposed published material cited in this reference. And a search using the name and title-and the sites search function- of this pub. yielded no results:

This article either needs to go, or be rewritten. ----

I'm confused by the statement "The blood pressure lowering effects in humans, however, was not statistically significant." that then references the article by Perrinjaquet-Moccetti et al. That research showed that olive leaf extract DID have a significant effect on blood pressure AND cholesterol.

Agree with Kapuku in that the results of olive leaf extract do appear to have a statistically significant effect on bp. Further evidence is found here: The authors concluded that the extract was comparable to Captopril in reducing bp for stage 1 hypertension patients. The extract also lowered triglyceride levels.

Dubious citation[edit]

I removed the following citation:

  • Dr Stevenson, L,. et al. Oxygen Radical Absorbance Capacity (ORAC) Report on Olive Leaf Australia's Olive Leaf Extracts, Southern Cross University, 2005.

This is dubious for several reasons: (a) There is no journal cited; (b) There isn't a link to the source (c) I couldn't find a journal or other reputable source when I did a Google search; (d) "Olive Leaf Australia" is a commercial brand; it's highly unlikely that any reputable journal would publish an article about a commercial product, as opposed to a more generic item.

In short, this seems highly likely to fail WP:RS. But if someone can provide the missing details, feel free to add this back to the article. -- John Broughton (♫♫) 03:23, 29 May 2015 (UTC)

In search of...other surfaces[edit]

The article reads:

Olive leaf extracts are sometimes used in skin creams and other cosmetics for application to the skin or other body surfaces.

Really? Maybe I've led a sheltered life, but it beggars my imagination that skin creams and cosmetics are used on body surfaces other than the skin. Stomach lining, perhaps? Tooth enamel? I will remove the last four words presently. Rivertorch's Evil Twin (talk) 01:59, 14 March 2016 (UTC)
