 * I've removed it, as it's not food but herbal medicine. Thomas Blomberg (talk) 12:56, 12 September 2011 (UTC)

This page could really use some help -- it's messy, weirdly written, and includes incomplete sentences. Kvcad (talk) 02:19, 27 June 2018 (UTC) Not NPV, unreliable and unscientific sources. Ingredient in some formulations of Essiac.

Problematic texts
Hi, if anyone's watching this. I've been updating/expanding the genus Rheum pages, and I'm about to seriously butcher this one. Reason is mostly because it is conflating info about different species, factually inaccurate, silly herbalism cheer-leading... I don't know if the sources are wonky or the editor was confused, but I must tackle this now. With shears. Sorry. Leo 86.83.56.115 (talk) 23:02, 20 March 2019 (UTC)

All these names are historical and apply to the dried root of at least 7 species. The chinese name just means 'rhubarb' in general, not specifically this species. Leaving this here till I figure out what to do with it:

Turkish rhubarb, Turkey rhubarb, Indian rhubarb, Russian rhubarb or rhubarb root (and within Chinese herbal medicine da-huang). 86.83.56.115 (talk) 23:11, 20 March 2019 (UTC)

(Foster): it was taken by an emperor in the Liang dynasty (557-579) for fever, used as gift-bearing means to an emperor of the Tang dynasty (618–907), used to combat the plague in the years which the Song dynasty ruled (960–1127), and used as a suicidal measure by a general of the Ming dynasty (1368–1644). 86.83.56.115 (talk) 23:59, 20 March 2019 (UTC)

A rhubarb monopoly initiated in Imperial Russia in 1731, stiffly regulating its trade from "China via the Asian steppes to Moscow and St. Petersburg, where its root was shipped to the rest of Europe." For 125 years thereafter, rhubarb-root imports were governed solely by what was known as the "Rhubarb Office". This "office" ceased to exist once China opened its ports to the Western nations, allowing for free trade. 86.83.56.115 (talk) 00:03, 21 March 2019 (UTC)

Rhubarb contains anthraquinones including rhein, and emodin and their glycosides (e.g. glucorhein), which impart cathartic and laxative properties. It is hence useful in cases of constipation. 86.83.56.115 (talk) 16:05, 7 April 2019 (UTC)
