CONCLUSIONS
Information from extensive literature review indicates that A. catechu has a broad spectrum of pharmacological effects. There are a number of studies which conclude that A. catechu is the main constituent responsible for oral cancer. However most of the pharmacological activities like antinematodal, antibacterial, anti-venom, antioxidant and molluscicidal activity of A. catechu are well accepted because of the wealth of scientific literature supporting these effects. More research should be undertaken to determine its efficacy against several diseases on man with respect to other natural products and modern drugs. Therefore, A. catechu, deserves more attention by scientific community and public health specialists to explore its full range of benefits in the welfare of the society.
