Scurvy

Papers On Health
Is a disease springing from disordered digestion, and caused
sometimes by partial starvation, but more frequently by a deficiency of
vegetable acid in the food. It often manifests itself in skin
eruptions, the skin peeling off in scales. To ward off or cure this
disease, fresh food should always be used, and salted or tinned foods
avoided. Especially should abundance of green vegetables and fruit be
used, and where such cannot be obtained in sufficient quantity, lemon
juice is valuable. Too much exposure, fatigue, and impure air, aided by
a wrong diet, are the causes that formerly made scurvy so prevalent in
the navy. It has almost disappeared since a regular allowance of
vegetable acid has been served out.
