Does anyone have a resource for making insulin. I know Lily was talking about discontinuing Bovine and Pork derived insulin. I am a late onset Type I and have only ever used the recombinant DNA derived Insulin. I have searched and only ever found a reference to a guy who kept his diabetic wife alive during WW2 with insulin he made from sheep pancreas. Anything would be great. It would be great to have a way to make insulin from local resources should the SHTF.
