This makes me wonder what else Grandma used to use in her herbs and teas....that would help improve our health? I think all of these millions in research are just wasted going down the drain...we ought to go back to the basics.
Well, my grandma believed in sassafrass tea in the spring "to thin the blood."
Also, I've just discovered guaifesin, a natural herb now in extended release tablets. In two days it cleared up bad ear and sinus congestion (it's a mucus thinning herb discovered in the 15th Century). It's used, too, nowadays for fibromyalgia.
