what was the indian legend about tea leaves?

Legend has it that Bodhidharma an Indian ascetic, who was a follower of Buddhism, cut off his eyelids, so that he stayed awake while meditating. However, tea leaves grew in the place of his eyelids. When these tea leaves were put in boiling water, it resulted in what we know as "tea".This is the reason behind tea being considered to be a deterrent to sleep.
