I've heard this many times; and I do know that there are very few insects that will eat it. I see a lot of hearsay on the net about it but has anyone seen of a study that could be referred to? --188.8.131.52 (talk) 21:37, 21 April 2009 (UTC)
I have tons of spearmint in my yard, and on a few of the plants, the leaves have purple veins. What is that? Rmpfu89 01:41, 28 May 2006 (UTC)
That would be mayan mint. It is possible that it mixed in with the spearmint. Dont quote me though.
What is "It is not a type of fern."? A clarification of a common misconception? If so, I think that should be mentioned in the sentence. I'm sure there are lots of things spearmint is not. ;) -- eLowar 13:59, 24 November 2006 (UTC)
- My thoughts exactly... I've never come across anyone thinking it's a fern, so I am removing the sentence. -- 184.108.40.206 00:48, 14 January 2007 (UTC)

syn. K. burkhardtis - vandalism?
Where is it said that it does not affect DHEA production? It cites the BBC news article, but nowhere in that article does it mention DHEA. —Preceding unsigned comment added by 18.104.22.168 (talk) 14:47, 28 November 2008 (UTC)
I am curious...what kind of habitat does spearmint naturally grow in? It grows easily in soil in my garden but I have never seen it propogate by seed there. On the other hand, I have found it naturalized in waterways and drainage ditches both in Pennsylvania and northeast Ohio. Does it require moving water? Cazort (talk) 14:49, 1 October 2009 (UTC)
A 2004 experiment which involved feeding groups of rats large amounts of spearmint water found that, after 30 days, "there were granular or ballooning hepatocyte degeneration and necrosis, sinusoidal and central vein dilatation" of the rats' livers. Here is a link to the study's abstract:
The effect was found to be more pronounced for spearmint compared to peppermint (Mentha piperita).

'Permanent reproductive damage' not correct
The wiki states that "the administration of spearmint tea to rats causes irreversible damage to the reproductive system of the male rat", and cites  (Kumar, Vikas; Mool Raj Kuralb, B.M.J. Pereiraa, Partha Roy (2008-08-18). "Spearmint induced hypothalamic oxidative stress and testicular anti-androgenicity in male rats – altered levels of gene expression, enzymes and hormones". Food and Chemical Toxicology 46 (12): 3563–3570.) as the source of that claim.
However, on further inspection of the paper, it would seem they say the opposite:
"...on long term treatments (25 and 35 days) there was significant decrease in the levels of CAT, SOD, GPx and GR in hypothalamus of treated rats. This showed that the administration of spearmint results in the development of oxidative stress in a time and dose dependent manner. However, this condition reverted back to normalcy when the treatment was discontinued after 35 days (data not shown)."
Although they say "We demonstrated that the short term use of these extracts may not cause severe damage to endocrine system but long term use of the same may lead to irreversible damage to various physiological systems", here they are talking about spearmint's renal and hepatic effects when they refer to physiological systems, not the sex organs which were affected by the endocrine system (as stated earlier in the paper).
I don't often edit articles myself, and I'd rather not bypass any normal protocol, so I'm proposing this statement be deleted as it spreads frightening misinformation.
