Not only one of the most invasive vining plants in my yard but as others have stated, by far the deadliest. If a child were to somehow ge...Read Moret a hold of the seeds and CHEW them and then swallow, they are in BIG trouble with little hope of treatment. The toxin derived from them is FAR more deadly then Ricin and among the top 3 deadliest Bio-Toxins known to man anywhere on the planet with no known cure. Symptom onset (Including respiratory failure, sinus tachycardia, severe abdominal pain among others.) has been known to take up to several days and by then can be nearly impossible to determine what the cause could have been so treating even the symptoms can be a total crap-shoot and even when administered has been shown in the past to be wholly ineffective. While there have been survivors who have ingested a single chewed up bean, it's still not a pretty sight. Nice way to spend a week in the ICU or even die eh? Abrus is no joke and not to be taken lightly.
Whoever wrote about homeopathic uses should be careful about what they write. While I haven't researched the leaves or flowers, perhaps there may be something to them, I'm not sure, but I would never condone owning this plant if there are kids and / or pets that are prone to chewing on things as the bright red and VERY numerous seeds can be very inviting.
Having said all of that above, the seeds (Also known as Crab Eye seeds) have been used in Native American culture in rattles and as beads since they are so "tough". So if very careful and diligent, the seeds have some Ethnobotanical use I suppose.
Personally, I snip every root I can find and try to introduce another plant in it's place in hopes of out-crowding this horrible plant. It climbs, it creeps, it spreads and even when flowering those short-lived, delicate little lavender colored flowers, have no cosmetic appeal whatsoever. Don't do it!
I have a question...
I was in Florida in June, and in a park in Miami, I saw a large number of similar seeds on the ground. The di...Read Morefference was that the seeds were solid red, without the black spot on them. Same bright red color, same shape. A similar looking plant to the photos here was evidently producing the seeds. Maybe the plant was a close cousin to A. precatorious? I can't find any pics that I may have taken of the plant to post here.
Any help would be appreciated!

Yes they're poisonous. About 100 times more toxic than ricin.
But they are also VERY tough seeds--no mammal is known that ...Read Morecan swallow one whole and digest it--thus the warnings about crushing/drilling/grinding etc.
These are a type of seed which is designed to pass through bird crops intact but scarified in order to sprout. I can't be certain, but I doubt that your average adult could chew a seed w/o soaking it or breaking teeth...but I know of no tests. The plant is found around the world in the tropics.
The poison (abrin) is a pair of proteins, abrin-a which acts as a catalyst (doesn't get broken down in use,) which destroys the ability of the cell to create proteins. This protein (or very similar protein) is found in many other species. Without a way into the cell, it's harmless.
Abrin-b protein is the key that lets the a protein into the cells--where it is estimated a single a protein can destroy 1,500 molecules per minute. Since the a protein is still intact when it leaves the cell, a single molecule can destroy hundreds of thousands of cells, which is why the lethal dose is so low.
There have been cases of children killed with a single seed (usually sucking on a necklace or the like--drilled seeds.)
The poison is destroyed by bleach 5% solution. It is otherwise VERY stable, if you were to find seeds in an attic in the north where the conditions varied from -50F to 130F and humidity from 0-100% for many decades, the toxin would still be effective.
"The toxic portion is heat stable to 140°F (60° C) for 30 minutes; at 176° F (80° C) most of the toxicity is lost in 30 minutes. EXTREMELY TOXIC - Lethal dose after oral consumption by humans is approximately 0.005-0.007 mg/kg."
Lethal dose inhaled or injected or absorbed is much lower--the stomach destroys quite a bit of the ingested material. A dose of 350mcg (.35mg--~1/1000th of an aspirin tablet) would be lethal to the majority of 100-150 pound persons.)
Oh, and it's NOT a fast poison! Nor is it painless, it works by preventing cells from functioning and reproducing, so it tends to produce a very painful death over many hours or days depending upon method of introduction.
There is no antidote, although the military has a partially effective vaccine against ricin (which is 100x less potent!)
They are very pretty! I suggest using them in patterns glued and rather than drilling for jewelry I'd mount them like stones. (Drilling the beads releases toxic dust, since it takes so little to be lethal, drilling a number of them would potentially be quite dangerous. If you drill them, I recommend working over a disposable paper or cloth soaked in 10% bleach, and a dust mask. It couldn't hurt to run the drilled beads in a bleach soak for a few minutes (runs some tests to see how long it can soak w/o deforming the bead.) At the least this will reduce the toxin available.
Medically, ricin-a (from castor beans,) which is similar to abrin-a has been tested against tumors, and ricin-b and abrin-b are being studied as potential carriers for medicines into cells--which would permit lower dosages, and perhaps even target particular organs.
Realistically, reasonable care to keep them intact and you'd be better rewarded by paying attention to how close you are to the car in front of you (3 seconds back!

I can believe one seller ,FROM FLORIDA,offer this plant for sale.Some people don`t care about the health of another people,when can make some income in their side or just ignore the information about it.
THIS PLANT IS WEED(spread like a bush fire in a pine forest),DANGER,HIGH POISON AND ILLEGAL TO SELL,TRADE,CARRY OR EXPORT TO ANY STATE.
The poison is LETHAL.
In others country's the mortal rate ,where this plant grow ,is very,very high.But doctors have not idea how to distinguish between the poison of this plant and the effects in the patients.And many time the death are cataloged like other cause.
The same happen in USA.
To gave an idea,we can call this plant "green ANTHRAX",to gave you an idea how bad is.
