Raw rice???

So I read that for suspected parasitic infestation, to chew 1/4 - 1/3 c. raw brown rice each morning, chewing each bite thoroughly until completely liquid before swallowing. Eat nothing else for 3 hours.

I'm currently searching other sites for more information. Apparently this is a big step in detoxing for parasites, also helping with bowel motions in case of constipation?

I imagine this would be alongside a diet high in leafy greens and easy-to-digest vegetables and juices.

Has anyone else heard of this - have you tried it - any opinions, good or bad?
