Introduction

Discovery of medicines began through serendipity and man’s quest for drug in nature. Since plants existed on earth from the very beginning of human evolution, the use of plants in the daily lives and in alleviating human sufferings is as old as human civilization on earth.

Bangladesh being a country of this Indian subcontinent also possess a great diversity in plants. Around two thousands medicinal plants in this sub-continent and 449 medicinal plants are enlisted in Bangladesh [3]. Though the exact number of used plants is unknown there are some common medicinal plants which are in use by kavirajes, traditional medicines for a long time. The existence of various tribes like Chakma, Marma, Rakhain, Tipra, Garo, Khashia with cultural diversity has also enriched the use of medicinal plants. This traditional attempt to treatment has survived the enormous take-over of modern medicine systems because of the belief of people in mother-nature. As a consequence the knowledge behind the use of medicinal plants have passed down from ancestors to predecessors. Some definite preparations and validation protocols for the use of some medicinal plants have been determined. Still the rural, tribal and folklore society admire the traditional use of plant extract or simple preparations like infusion, decoction, powder from plants due to the great availability of the plants. One of the major use of medicinal plants is in infectious diseases to treat them or to reduce the symptoms. Infectious diseases are diseases caused by pathogenic microorganisms like bacteria, virus, fungi. Pneumonia, meningitis, food borne infection, ear infection, urinary tract infection, STD like gonorrhea, syphilis are being treated by various plants. The most common use is still in treating common cold, sinus infection and skin infections. Besides, with the advancement of science people have come to know that the plants at our reach contain magically bioactive components like alkaloids, glycosides, flavonoids, tannins, terpenes, resins, gums, mucilages, antioxidants at small dose. People still rely on these remedies generally in conditions which are not generally regarded as life threatening.
