isn't Sago Palm (Cycas revoluta) highly toxic? i don't think it's edible...

[procaryote]

It's a staple food in some cultures. It needs preprocessing, but people have been doing that for a while

A lot of vegetables are toxic when raw, but safe after cooking. My favorite among these is mandioca, when it’s cooked and then fried. Goes well with churrasco.
