scurvy

Scurvy is best known as the disease sailors used to get on long voyages, but it can affect anyone who goes too long without enough vitamin C. Before refrigeration and easy access to fresh food, people with limited diets could become very weak, develop swollen or bleeding gums, bruise easily, and find that cuts healed slowly. Today it is rare in places where fresh fruit and vegetables are easy to get. You may also hear "scurvy" used as an adjective for something mean or low, as in a "scurvy trick."

Scurvy is a disease resulting from a deficiency of vitamin C (ascorbic acid). For centuries, it plagued sailors and explorers who spent months without access to fresh fruits and vegetables—the primary sources of this vital nutrient. While often associated with pirates and 18th-century naval life, scurvy can affect anyone whose diet consistently lacks sufficient vitamin C.

The symptoms develop gradually, starting with weakness, fatigue, and sore limbs. As the disease progresses, sufferers experience bleeding gums, loose teeth, skin hemorrhages (bruising easily), and poor wound healing.

Historically, understanding how to prevent scurvy was a major breakthrough in naval medicine. James Lind's experiments helped show that citrus fruits could prevent the disease, and over time navies learned to reduce cases by improving sailors' diets. This eventually led to the British Royal Navy issuing lime juice as a standard ration, earning British sailors the nickname "Limeys."

Today, scurvy is rare in developed countries, but it can still occur in individuals with severely restricted diets or malnutrition. Beyond the medical context, the word remains in the English language as a biting adjective. To call someone a "scurvy knave" is to call them despicable or worthless. So, while you might picture a pirate with rotting teeth when you hear the word, remember it's both a serious nutritional condition and a colorful way to describe someone's low-down behavior!
