Medicinal plants are of great importance to human health. This is why the World Health Organization estimates that 80% of the population in developing countries relies on traditional medicine for their primary health care. Therefore, medicinal plants play important role in the socio- cultural and therapeutic needs of peoples. Some of these plants are used as spices and foods, also serve as a resource for research and development of new drugs. In Africa and elsewhere, several ethnobotanical surveys conducted, showed that Sorghum bicolor (L.). is a medicinal plant well known and widely used in the treatment of various infections.
This study allowed us to detect the presence of different pharmacognosic parameters in Sorghum bicolor (L.) drug according to botanical standard and WHO guidelines. The value of moisture content found is satisfactory as the moisture content level in the drug studied allows good conservation and prevents oxidative reactions, fermentation and microbial growth. In light of these results, pharmacognostic analysis and physicochemical characteristics can help in the efficient utilization of this plant as part of a standardization policy, identification and research on Sorghum bicolor (L.) drugs.
