Have any of you ever heard of Parkinsons of the throat? I am taking square dance lessons. The caller/ instructor has this throat trouble and says that it is hereditary (many people in his family have been diagnosed with it) Doctors have told him that he is a canidate for trying botox injections in his throat. Last visit, he told the doctors about the fava top tincture. The doctor actually knew about the bean ....he told him , Try it....if it works, great. He is scheduled to go in for botox in Jan or Feb . I gave him a very small amount to test....we shall see if it helps ! It sure helps with my voice & singing
