The Sacred Science (2011)

Diabetes. Prostate cancer. Alcoholism. Parkinson's diseases. Just a handful of many common illnesses that Western medicine has been inadequate in curing or treating. Witness the story of eight brave souls as they leave the developed world behind in search of deeper answers. Living in seclusion for one month in the heart of the Amazon jungle, these men and women take part in the powerful healing practices of Peru's indigenous medicine men, working with centuries-old plant remedies and spiritual disciplines. In their most desperate hour, these patients are forced to confront not only their physical ailments, but their own spiritual and psychological barriers in the process. Five will return with real results, two will return disappointed, and one won't come back at all.
