I have heard that several tennis players (as well as some baseball players) have been using an herbal tea of some sort that is supposed to help increase a person's spatial awareness. Has anyone else heard about this? If so, do you know what this herb is? Apparently, it is perfectly legal, and some athletes supposedly swear by the stuff--claiming that it allow them to track a moving ball more accurately. I have been checking around for information about such an herbal medicine, but I haven't had any luck finding any more out about it. Just wondering. Thanks.
