Elixir by Braver, Gary. Mass Market Paperback edition. ISBN: 9780812575910.

When biologist Chris Bacon headed for the unspoiled rainforests of Papua New Guinea in search of medicinal plants, he had no idea that he would bring home a rare flower rumored by a tribal shaman to prevent human aging. Driven by fountain-of-youth dreams, he plans to turn the flower into an elixir of youth and health. But as Chris begins tampering with the ultimate secret of nature, he unleashes forces that not only threaten his own family, but expose the world to unimaginably horrific consequences.
