Talking about the United Society of True Believers in Christ’s Second Appearing – a religious group commonly known as Shakers -- doesn't mean this is an episode about religion. They were disciplined and hard-working, and they were also innovative -- a good combination of characteristics that helped them finance their communal lives in a few successful ways. Their most successful business didn’t come from their famous furniture or inventions like the clothes pin, though. It was their knowledge of herbs and their practice of botanical medicine -- and what it was like for them to practice patent medicine in a time of snake oil sales.
