If you look on the Eli Lilly website or check their wiki page you will get some vague explanation about how Mr. Lilly got his start and what his first potions actually were. This is what it says: From its facilities in Indianapolis the company manufactured and sold “ethical drugs” for use by the medical profession. Lilly’s medicines included labels that disclosed product ingredients. And what do you suppose these ethical drugs were?
That’s right…Cannabis Extract. Also Cocaine Extract. Now you know why of the first 3 scientists hired 2 were botanists and one was a chemist.
