The poison is in the dosage. In moderate doses chlophyll is salubrious and in heavy doses it gives some people severe digestive tract upsets. No record of it killing anyone, as far as I know.
Google Chlorophyll poisoning for details.
In heavy dosages it also tastes greeeeeeeeeeeeeeeen, which some find objectionable. Like me for instance,
Indeed. I have ate pure undried bud before. It made me throw up and gave me acid reflux. Nothing that was permanent.... But an unpleasant experience none the less.
I wouldnt say its bad, might just have a really 'green' taste.
After you seperate the butter and water, you can throw it back in the pot with fresh water to help get rid of some chlorophyll. You can keep repeating this process also.
