The article claimed that bixin, the coloring principle, "can be extracted by stirring the seeds in water." Is there a reference for this? It seems that bixin is oil-soluble, so by stitting the seeds in water perhaps one obtains a suspension or paste of the powdered arils, not a true extraction. is this right? -- Jorge Stolfi ( talk) 16:58, 27 March 2015 (UTC)
There seems to be a variety of the tree whose pods change directly from pale green to brown, without ever becoming red. Some of the images in the gallery may show this variety. Is it just a variety, or a different species? -- Jorge Stolfi ( talk) 17:26, 27 March 2015 (UTC)
The dark red waxy-looking layer around the seeds, that contains the coloring matter, is said to be an aril in some aticles, or pericarp in others. Which is correct? -- Jorge Stolfi ( talk) 19:03, 27 March 2015 (UTC)
Some parts of the articles have the same content — Preceding unsigned comment added by 177.65.45.184 ( talk) 01:02, 21 February 2017 (UTC)
There are several claims in the article that this plant has been used "traditionally" (since when?) in India in Ayurveda and in Nepal as if the plant was local. It is most likely post-Columbian and any claim that it is a pre-Columbian import requires truly rigorous evidence. Shyamal ( talk) 15:11, 10 October 2018 (UTC)
