There is a growing interest in medicinal plants and traditional medicine; with in the last decade the governing bodies of the World Health Organization (WHO) of the United Nations and the world commission of environmental development have called for intensification of efforts in the development of national traditional medicine activities. Many countries have responded by emphasis on the utilization of traditional remedies including medicinal plants.The medicinal value of plants lies in some chemical substances that produce a definite physiological action on the human body. These phytochemicals are the active constituents that exhibit some biolological activities concerning antioxidant, antimicrobial, antiinflammatory, and anticancer activities. Exploration of the chemical constituents of the plants and pharmacological screening is of great importance which leads for development of novel drugs.
