If someone just ground up a castor bean, which is completely harmless, would it also test positive for Ricin?
Ricin comes from castor beans, and is a by-product of making CASTOR OIL.
The plants and the beans are beautiful and the plants are very common ornamental shrubs.
I used to play with castor beans when I was a child. I used them as cargo in the freight cars of my Lionel electric train.
Ingesting the beans will make one ill, but is very rarely fatal. Getting it directly into the blood stream is the lethal shot. No antidote. The KGB loved using it...
It requires a simple chemical extraction process; which I won’t discuss here.
