@cs3000 - Interesting thread. Most of it is above my understanding.

Manuka honey has a high level of Methylglyoxa. Up to 100 higher than regular honey. Great for skin cancers but diabetics might need to understand the possible risk.

Methylglyoxal levels also appear to be higher in Alzheimer patients.

Methylglyoxal, Glyoxal, and Their Detoxification in Alzheimer's Disease (2006)

I am wondering if the oral use of Methylglyoxal for cancer could cause other issues in the patient. Sort of a Whack-A-Mole of diseases.
