I would really like to see you add a disclaimer to this post that this is NOT medical advice.
Sugar, including honey, is known to FEED cancers and it the first thing we feed lab rats for 3 weeks in order to GIVE them cancer for study purposes.
I'm in much agreement with you though about building our natural immune system. And I believe in the power of BELIEF and PRAYER often being enough, which is maybe why the Good Friar had so much success despite the sugar.
