Wow. As I have said, I am a huge fan of grasses and have had great experiences with wheat grass sprouts. After hearing so many great things about barley grass you can bet it is on my list of things to plant this spring.
I am sorry for your doctor friend and I don't doubt one bit that they wanted to run him our of town. I was treated like a criminal for refusing to take my prescriptions, and was denied the opportunity to receive disability because I would not sign an agreement to take everything that was prescribed to me. They tried to dangle the survival of my family in front of me, but I didn't take the bait.
In the long run, your doctor friend will be thankful that he courageously put his understanding into practice and saved lives. There is just no compromising or reasoning within that system.
