In the freshness of the early morning in the jungle we can see many varieties of plants and trees at the backgound of this landscape and a stream that comes from a river of the deep jungle. We also appreciate some trees like Oje and Cumala and other ones. In the first level we can see in a definite way to the Chirik-Sanango. The Chirik-Sanango is a shrub which has till five meters high with purple and white flowers. It is a plant without gender. It is used the bark in the folk medicine to cure rheumatism; it is a good medicine any time of the year.

Pharmacognosy is the study of medicine from natural plant sources. For decades pharmaceutical companies were interested mainly in chemical synthetic drugs. The "new pharamaceutical" companies work with ethnobotanists and local shamans, native medicine men, for medicines ...learning traditional uses of plants for remedies. They combine this knowledge with scientific knowledge and current laboratory research.

"Nature produces chemicals that no chemist would ever dream of at the laboratory bench."
