Language is the unique power bestowed upon human being to represent and share unbounded thoughts. Its evolution is one of the most interesting and significant evolutionary events which has occurred in the last 5–10 million years, and indeed during the entire history of life on earth.Language has a long evolutionary history and is closely related to the brain, but what makes the human brain uniquely adapted to language is unclear. The regions of the brain that are involved in language in humans have similar analogues in apes and monkeys, and yet they do not use language.Given its central role in human behavior, and in human culture, it is unsurprising that the origin of language has been a topic of myth and speculation since before the beginning of history.
India has a rich abundance of medicinal plants and is remarkable in that these plants are used by all sections of people either straightforwardly as society remedies or in various indigenous systems of medicine or in a roundabout way in the pharmaceutical preparations of current medicine. The knowledge of medicinal plants has been gathered in many centuries based on various Indian systems of medicine such as Ayurveda, Unani, and Siddha. WHO has listed more than 21000 plant species used far and wide for medicinal purposes? In India, about 2500 plant species are being used in indigenous systems of medicine. There are two types of sensitivity tests i.e., diffusion and dilution methods used to determine the antibacterial potential of the preparations of solvent extracts. Based on the diameter of the zone of diffusion (inhibition) method represents a qualitative test that designates the classification of bacterial species either sensitive or resistant on tested the sample of plant extract.
