Any case studies available on reversing peripheral artery disease?

I don't have any published material available on this but I have met a couple of people who have tried it with satisfactory results.They have felt a lot of improvement symptomatically.As far as cinnamon goes,yes it helps.A pinch of crushed and powdered cinnamon to be kept soaked in half a gl of water(say 100ml)overnight to be consumed in the morning on empty stomach once a day.No.2...one gl of raw Gourd juice (and not bitter gourd) to be taken empty stomach each morning helps to open up clogged arteries.No.3...there are certain yoga exercises which are beneficial in this condition.
