The Life Giving Plant

This is a story about a multi billionaire from Mexico who had multiple health problems, and was going to be hospitalized for the rest of his life. Not willing to accept such a diagnosis, he comes up with a devious plan and manages to escape from the hospital. He is fleeing to his friend's place in Brazil when his chopper crashes in the Amazon rain forest.
When he wakes up from his coma after about two months, he finds himself 40 years younger and cured of all his health problems, all thanks to the native Indian tribe that rescued and treated him with herbal medicine. He returns to Mexico, and instantly becomes a media sensation as he tells his story, which results in a global hunt for these herbal plants.
The billionaire feels guilty about the harm that is being visited on the Amazon forest and the Indian tribes because of his notoriety, and decides to return to Brazil to help the ones to whom he feels indebted. He makes his way into the Amazon forest and eventually finds the very native tribe that saved his life.
