I met a nice person from Eretz Yisrael – Rabbi Guberman. He said he found a bark of a tree that one uses to make as a tea that naturally lowers blood sugar and cholesterol. He said it may not eliminate the need for insulin but can reduce the need for it. If you want more info, let us know. His sister’s website on herbs is http://www.herbs.co.il/ (It is in Hebrew. If you want the English or other Translation use translate.google.com and type url/website address)
