French researcher Victor T. Junod was the first to describe symptoms of narcosis in 1834, noting the functions of the brain are activated, imagination is lively, thoughts have a peculiar charm and, in some persons, symptoms of intoxication are present.
The word green comes from the Middle English and Old English word grene, which, like the German word grÃ¼n, has the same root as the words grass and grow. It is from a Common Germanic *gronja-, which is also reflected in Old Norse grÃ¦nn, Old High German gruoni (but unattested in East Germanic), ultimately from a PIE root * ghre-to grow, and root-cognate with grass and to grow.
The modern English word green comes from the Middle English and Anglo-Saxon word grene, from the same Germanic root as the words grass and grow. It is the color of living grass and leaves and as a result is the color most associated with springtime, growth and nature. By far the largest contributor to green in nature is chlorophyll, the chemical by which plants photosynthesize and convert sunlight into chemical energy.
