Talk:Solanum nigrum

message: I expanded the page slightly while I was looking for an already made article. I needed it for a text-based RPG I was on, where I teach Herbology, along with a few other things. Dragon Expert 15:53, 19 January 2006 (UTC)

message: The 28 April edit by 65.214.154.131 changes the Tamil name from manathakkali to sundaikkai.  However, the Solanum torvum page identifies that nightshade as sundaikkai.  Most of the literature I've seen does so as well, and identifies S. nigrum as manathakkali (for example, (Mohan et al., 2008).  So I'm reverting this edit.  If someone has a contrary reference, I'd appreciate seeing it.  Thanks!

here, so I can then eat it?
Also http://www.hort.purdue.edu/newcrop/Crops/Wonderberry.html says it is OK...

::"There is a lot of disagreement over whether or not the leaves or fruit of this plant are poisonous. Views vary from relatively poisonous to perfectly safe to eat. The plant is cultivated as a food crop, both for its fruit and its leaves, in some parts of the world and it is probably true to say that toxicity can vary considerably according to where the plant is grown and the cultivar that is being grown. The unripe fruit contains the highest concentration of toxins."

: So, basically, unless you know for sure whether it's the right soil, environment and cultivar, don't eat it. bogdan 12:59, 27 May 2006 (UTC)
thread_title:  poison 

message: Please do not remove the well referenced toxicity section. There are substantial academic references to the presence of toxic levels of glycoalkaloids in various plant parts of S.nigrum. It's also vital and responsible that this toxicity information is available along with the culinary and herbal use information, otherwise this article risks being a hazard to would-be wild-crafters who may not understand the toxicity risk with uncertain strains. 
The toxicity section is also balanced. It doesn't necessarily contradict culinary and medicinal uses. John Moss (talk) 00:09, 18 January 2012 (UTC)
thread_title:  Please do not remove the toxicity section 

message: The new edit on the toxicity section is interesting, but is probably not objective in a wikipedia style. This edit removed nearly all the historically recent phytochemistry references that contradicted the authors assertion that there was no recent evidence of toxicity. I find that a big worry. We have to be very careful not to ignore scientific references that don't suite a particular perspective when it comes to an objective encyclopedic viewpoint. At the heart of toxicology is the phytochemistry of the plant, and regardless of whether there are no recent cases of poisoning, if the toxins are present in high enough amounts in Solanum nigrum - then it's considered toxic regardless. I will try and tease out the facts on the chemistry references, but I have to say, this new toxicity section is looking heavily biased and needs a substantial review. Also, some assertions are not supported by the reference material. However, I wont just go straight back to the previous edit, but will see how I can synthesize this new edit with with what was written previously. The only problem with this current edit is that it may be dangerously misleading, so I will indicate bias.

thread_title: New edit on toxicity section

message: It is slowly being straightened out; using DNA sequences and chromosome counts as well as a few anatomical markers the issue is becoming clearer. Briefly, after reviewing the 21st-century literature, the important species seem to be:
* S. americanum - North America, black fruit, probably strongly poisonous and may cause harm even when fully ripe. This may be the species responsible for all black-berried nightshade fatalities reported from North America
* S. nigrum - originally Europe and surroundings but widely introduced, black fruit, poisonous except maybe when fully ripe. Ate it myself, tastes slightly "off" (like sprouting potatoes) even when fully ripe so probably not recommended
* S. opacum - Australia, lime-green fruit, somewhat poisonous but maybe edible when ripe
* S. ptychanthum - Atlantic North America and Caribbean, black fruit, somewhat poisonous but maybe edible when ripe
* S. retroflexum - originally Africa, black fruit, edible and widely cultivated as "S. x burbankii" ("wonderberry"/"sunberry"). Tasty and sweet and definitely lacks the "off" taste of true S. nigrum
* S. scabrum - originally Africa, black fruit, probably fully edible ("garden huckleberry") but locals use the berries as dye and only eat the leaves so the berries are probably less tasty than S. retroflexum
* S. (villosum) alatum - Europe and surroundings, red fruit, probably somewhat poisonous but possibly some strains exist which are usable as leaf vegetables
* S. (villosum) villosum - originally Europe and surroundings, yellow fruit, maybe somewhat poisonous but as far as I can tell quite edible when ripe and very tasty and refreshing  — Preceding unsigned comment added by 85.197.53.185 (talk) 20:53, 19 January 2018 (UTC)
