Abstract

Plants have contribute enormously to the livelihood of human being. Besides theis major use as the sources of food shelter materials flavour and fragrance plants have been the main source of medicines and health care preparations. Human curiosity and their desire to understand their surroundings have evolved into scientific investigations which eventually led to the proliferation of various scientific endeavours as we know today. Investigations on medicinal plants have led to the development of modern drugs to combat human and animal ailments. Various scientific techniques have also been developed as the result of these investigations. In our effort to develop the scientific capability in this country we have embarked on the investigation of our medicinal plants. The outcomes of this effort are several papers which have been published in reputable journals as well as patents. Recently there is strong resurgence of interest in the use of medicinal plants or herbal medicines in the global sales are expected to reach 23.2 - 62 billion and the annual growth is estimated at 10-20. The main reasons leading to this trend include the rising cost of medical treatment and the belief that products derived from natural sources are safe. The fact that many of the current modern drugs were derived from plants has also led to the belief on the efficacy of herbal products. The rising popularity of herbal medicines has led to the growth of the industry and the lack of stringent regulations relating to the use has raised concern with regards to the efficacy and safety of the products. Several examples on the detrimental effects of herbal preparations have been reported due to intended or unintended mistakes. Several other medical issues include the compatibility of one herbal preparation with other drugs or herbal preparations when used concurrently dosages as well its real medical values since very few comprehensive clinical evaluation were done on these preparations is entirely different from drugs.
