There is a herbal tea called Ku Dan that I know from my friend's tea shop (Specialtea.ca) in Montreal,Canada which is being successfully used by 2 others friends of mine to regulate their glucose levels. Usage is as simple as drinking the infusion at least twice a day preferably right after meals.
This herbal tea appears to have a triple effect: lowering of blood glucose, lowering blood cholesterol and lowering blood pressure.
This is no replacement solution to exercise and proper diet, of course, but can be an excellent addition to a balanced program to increase efficiency and perhaps add some extra margin against 'mishaps' and accidents.
I believe medication should always be considered a temporary patch solution.
Good luck
keep me posted if you decide to try it...
