I don't know enough about it but I did find out that many types of bamboo are just so extremely bitter that they can't be considered edible. Also, researching it, a bit, and finding out about hydrogen cyanide in fresh bamboo didn't help me to feel better either. In all honesty, I don't really know whom or what to believe ( as the truth any longer, these days ) but here my body's communication was clear enough ( as it usually is ).
