This installment of Jewels sees Dr. Gary Strobel travel from the lush forest of South America to the clinical world of the laboratory. But the lab is no less exciting than the field, especially since some of the samples Strobel collected on his trip are providing dramatic experimental results. One particular endophyte under investigation prevents fungal growth - not that interesting by itself - but truly remarkable when we learn what else this compound is capable of. Is this micro-organism the missing link in finding a cure for the world's most deadly disease? Find out in part 2 of "Jewels of the Jungle".
