Botox injections are extremely useful in erasing the appearance of frown lines and wrinkles, but scientists have discovered an entirely different use for the powerful toxin.  The injections are improving the quality of life for people who suffer from abnormal sweating.

According to MSNBC.com, researchers have discovered that Botox injections are effective in treating hyperhidrosis, a condition characterized by profuse sweating.  In a study of 20% patients who sweated an average of four cups over a period of eight hours, the injections reduced sweat production to normal levels.  After two weeks, patients began to sweat more heavily, but even after six weeks, sweating was reduced to its original rate.  The effect is only temporary and injections will have to be repeated every three to six months.
