Me either, up until yesterday. I had bought a package of mixed nuts and as I was eating them, I was thinking about all of the shells that used to be around all the nuts. I could place all of them in my mind except the cashew!
After researching, I have a whole new appreciation for cashews & wonder why they're so cheap - considering their shells contain anacardic acid, which on contact, produces a response similar to poison ivy and the cashew nuts (seeds) have to be roasted outdoors to destroy the toxin and make them edible. (Outdoors, because the smoke also creates a skin/lung reaction similar to burning poison ivy.)
One cashew nut (seed) grows below each cashew apple. Cashew apples are edible, but the skin is fragile, making it unsuitable for transport. A lot of the tree is used for medicinal purposes, and the anacardic acid itself can be used to fight against tooth abscesses, MRSA, acne & TB.
I'm truly amazed at this plant.
