I found your this question posted at some other place.But I guess there is some relation between these two things....There is lot of scope for research in this field....as psychosomatic herbs in future treatment of diabetes.
I just asked few of friends from North India about ppl who consumes Bhang everyday...and found that those ppl don't get diabetic.
Further,there is recent patent awarded to one person from Jaipur for his research on Mitragyana parvifolia for treatment of diabetes.
The same tree/plant from Thailand in called Mitragyana spaciosa or Kroth is banned at most of place as psychosomatic.
However this Mitragyana parvifolia is not psychosomatic.Infact its sacred plant.its called Lord krishna's Kadamb.there is also one myth that leaves of this tree turns out like cone.And Lord Krishna use to eat Butter from those cones.
Guess Lord Krishna was also on LCHF.
Radhe radhe bolo.....jai Kanhiyaa lal ki.......
