A little quick search on google showed several sites using this info citing wikipedia as a source. Which is quite horrifying seeing as this is a very sensetive piece of information that could potensially be the difference between life or death for "home medicators" and wiki still needs citation for this! This should really be take of the page until proven or at least citated!!!--[[User:Hodeken|Hodeken]] ([[User talk:Hodeken|talk]]) 18:02, 5 June 2012 (UTC)

Annual production

Why does this page tell me that the world production of castor seeds is one million tons per year and the article about ricin tells me that 100 million tons are processed each year?

Klaus

100 million tons seems to be an error; see talk:Ricin. This has been corrected in the article. Elphion (talk) 13:46, 29 February 2008 (UTC)[reply]


Article name

Why is this article titled "Castor bean"? That refers to the seed. The name of the plant (according to Merriam-Webster's dictionary), is the "Castor-oil plant". Since when is a plant called a bean anyway? Rt66lt 17:41, 16 December 2005 (UTC)[reply]

most poisonous plant

Guiness World Records (published editions) record the Castor <a href="http://en.wikipedia.org/wiki/archive/oil">Oil</a> Plant to be the world's most "deadly" plant. "A particle from the Castor leaf the size of a grain of sand can kill a 160-pound adult". Why isnt that in the article!!!? See this website http://library.thinkquest.org/C007974/1_3cas.htm AJ24

Because you haven't added it yet? :) dougmc 22:30, 9 October 2006 (UTC)[reply]
Also, it's not true (talk:Ricin). Elphion (talk) 13:46, 29 February 2008 (UTC)[reply]
The most toxic substances by amount are
1. Plutonium
2. Botulism toxin
3. Ricin poison.
I could go on but the point is that could be the most toxic plant. Also, Elphion, this list is talking about toxicity of the POISON to humans, toxicity to other life forms obviously varies hugely with it being completely benign to some plants, as well as the fact that the levels of the POISON in each PLANT vary wildly. 216.249.58.67 (talk) 17:12, 7 October 2009 (UTC)[reply]


I would believe that it's use in suicide is uncommon as ricin poisoning takes a few days to kill a person, but will still be fatal with a smaller dose of any other plant. But I do have a hard time believing Ricin is the third most toxic substances, I was just reading about Abrin, which has a LD50 of >300ng, far less then ricin. — Preceding unsigned comment added by 66.62.194.227 (talk) 15:07, 11 May 2012 (UTC)[reply]

Ricin-Killing of Gorgi Markov thru KGB in London

and what about the umbrella killing of bulgarian journalist Gorgi Markov, in London, due to 10 microgramm of Ricin? In contrast to other killing agents, ricin provoces a leucocytosis, with fever. Ricin can be prepared easily in the kitchen by stirring the seed with an ionic exchanger and eluting from the filter with mannose-sugar. There is a lot of to tell about the medical problems regarding ricinus communis, e.g. the allergic reaction to the proein content. There should be a link to "ricin" of wikipedia.—Preceding unsigned comment added by Kaltenbrunner (talkcontribs)

There is a link to ricin. The other data you provide, you can add it to the article. --Dirk Beetstra T C 19:57, 15 December 2006 (UTC)[reply]

Las Vegas incident

I removed the section on 3/2008 Las Vegas incident. According to the provided source no information on the manufacture was known. The man did not die, but is in critical condition. Add it back without inferences. 71.217.210.55 (talk) 03:47, 2 March 2008 (UTC)[reply]

Whoever has been editing the article did not restore information about this incident. I have added a neutral notice about it. Elphion (talk) 22:48, 2 March 2008 (UTC)[reply]

Castor Beans plant as companion plant in gardens.

Castor Bean plants are also known as "mole kills" in the south. They are planted in gardens or landscapes because the roots are poisonous to burrowing animals. —Preceding unsigned comment added by 72.243.142.178 (talk) 13:12, 17 November 2008 (UTC)[reply]

Animal interactions question

There seems to be a paradox in the section about animal interactions. The point is made that it is a favorite food of the Tambourine dove, and then the next statement points out the toxicity of its seed. When you follow the link to the Tambourine dove's page, it says the dove feeds on the seeds rather than on the foliage, but makes no explanation of how the dove handles the toxin. Wonder how the Tambourine dove consumes the seeds without suffering the consequences??? I did not find much after searching the Internet, although I see the fact--the dove eats the bean--repeated a lot. Seems like this apparent paradox should be resolved with additional information if available, but I sure didn't find anything. I did see where parrots handle toxins by eating clay and removing the seed coat of some seeds. I did add the statement about ducks being more tolerant to ricin than mammals.

Questionable claim in Toxicity section

We see this: "In fact, ricin has been investigated for its potential use as an insecticide. It is also the source for undecylenic acid, a natural fungicide."

At the link to undecylenic acid, http://en.wikipedia.org/wiki/Undecylenic_acid, it says "Undecylenic acid is produced by cracking of castor oil under pressure." Cracking castor oil under pressure does not involve ricin, so which is correct? EdwardEditor (talk) 21:46, 21 March 2010 (UTC)[reply]


lethal ingested amount problem

according to this page http://en.wikipedia.org/wiki/Ricin#Overdosage the lethal amount is 5-20 seeds and on this page its 4-8 which is it i personally think 5-20 is more accurate as according to nhs ricin poorly absorption. also this part (If ingested, symptoms may be delayed by up to 36 hours but commonly begin within 2–4 hours) there is no mention of it on reference 6 were did this statement come from?.

Useage of the pressed seeds after removal of oil

Does anyone know if the pressed, de-oiled material is used for anything. Most other oil plants produce an edible material which can be added to animal feed, but what happens to the de-oiled material? Could the ricin content be removed by enzymes or something like citric acid? This could create a resource. — Preceding unsigned comment added by Colchemy (talkcontribs) 15:10, 11 October 2011 (UTC)[reply]

Absolutely Horrifying

"In most cases, on ingestion of the broken seeds, drinking a teaspoon of cold-pressed castor oil will prevent any poisoning" A little quick search on google showed several sites using this info citing wikipedia as a source. Which is quite horrifying seeing as this is a very sensetive piece of information that could potensially be the difference between life or death for "home medicators" and wiki still needs citation for this!
