Summer Complaints. The first I heard that term was about annual summer visitors to the coastal communities of Maine. But, the name had an earlier etymology on the coast. Older residents could speak authoritatively of spring complaints, fevers, chills, and illnesses that came on with the change of the season in the spring. Once upon a time, every grannie would have had a specially concocted mixture of herbs and secret ingredients that everyone in the family would be forced to consume, along with the Cod Liver Oil that was a medicinal standard. A spring tonic.
