They are the green artichokes that you steam, then dip the leaves in lemon butter and scrape off with your teeth. They have edible hearts and an inedible choke.
I followed the SCD for ONE MONTH, and I never had another problem with my stomach. Never. Ever. I was even able to resume a normal diet after that month.

You have nothing to lose but the suffering. I am now able to live the life of a normal, carefree 27-year-old.
