It is always important to learn how to safely harvest and process plants. You can't treat a plant like every part is the same, like you can just grind it up and extract a refined, marketable product.
Peach pits and apple seeds contain cyanide. Green potatoes can block absorption of nutrients and make you slowly starve. Uncooked taro will make your mouth prickle and itch painfully. Unopened ackee will straight up kill you dead.
To use a plant, to benefit from a plant, to care for a plant... you first have to understand the plant.
And by the way, ackee is awesome.
