An anodyne is anything that helps to reduce pain. There are a lot of herbs and other naturally growing products that can act as analgesics. Grow thick anodyne flowers, and
you have found yourself a source of natural pain reducing agents that can act just as effectively. An advantage with using natural products is that most of them have no side effects. So you are saved the likelihood of stomach upsets and other problems that seem to accompany most over the counter pills that most modern day busy people are accustomed to ingest.
