Scurvy was a scourge amongst sailors, with hundreds of thousands dying during the American colonial period. Before the concept of vitamin deficiency was known to the world, physicians struggled to find what caused the disease. That did not stop them from developing both herbal and chemical treatments with mixed results. Join Dan Marshall as he demonstrates the tools and techniques of turning simple ingredients into medicine in the 17th & 18th centuries. Dan will explore both European and American colonial sources that shed light on how this knowledge crossed the Atlantic and how it was put into practice here. Dan Marshall has shared his love of history with the public for 25 years. He is currently a Salem Historical Society Board Member and the Director of Education & Interpretation with the Lexington Historical Society. This Trails & Sails event is sponsored by The Witch House and the Salem Historical Society.
