Scurvy (N.Lat. scorbutus) is a disease resulting from a deficiency of vitamin C, which is required for the synthesis of collagen in humans. The chemical name for vitamin C, ascorbic acid, is derived from the Latin name of scurvy, scorbutus. Scurvy leads to the formation of spots on the skin, spongy gums, and bleeding from the mucous membranes. The spots are most abundant on the thighs and legs, and a person with the ailment looks pale, feels depressed, and is partially immobilized. In advanced scurvy there are open, suppurating wounds and loss of teeth.

Scurvy was at one time common among sailors, pirates and others aboard ships at sea longer than perishable fruits and vegetables could be stored, and by soldiers similarly separated from these foods for extended periods. It was described by Hippocrates (c. 460 BC–c. 380 BC). Herbal cures for scurvy have been known in many native cultures since prehistory. In 1536, the French explorer Jacques Cartier, exploring the St. Lawrence River, used the local natives’ knowledge to save his men who were dying of scurvy. He boiled the needles of the arbor vitae tree (Eastern White Cedar) to make a tea that was later shown to contain 50 mg of vitamin C per 100 grams.[1][2] Such treatments were not available aboard ship, where the disease was most common. It was a Scottish surgeon in the British Royal Navy, James Lind who first proved it could be treated with citrus fruit in experiments he described in his 1753 book, A Treatise of the Scurvy.[3]

In infants, scurvy is sometimes referred to as Barlow’s disease, named after Sir Thomas Barlow,[4] a British physician who described it. (N.B. Barlow’s disease may also refer to mitral valve prolapse.) Other eponyms include Moeller’s disease and Cheadle’s disease.

Scurvy does not occur in most animals because they can synthesize their own vitamin C, but humans, other primates, guinea pigs, and a few other species lack an enzyme necessary for such synthesis and must obtain vitamin C through their diet. Vitamin C is widespread in plant tissues, with particularly high concentrations occurring in citrus fruits (oranges, lemons, limes, grapefruits); tomatoes, potatoes, cabbages, and green peppers are also good sources of this vitamin.

Untreated scurvy is invariably fatal. Since all that is required for a full recovery is the resumption of normal vitamin C intake, death from scurvy is rare in modern times.

Scurvy was probably first observed as a disease by Hippocrates.[5] In the 13th century, the Crusaders frequently suffered from scurvy. Scurvy was one of the limiting factors of marine travel, often killing large numbers of the passengers and crew on long-distance voyages. It even played a significant role in World War I.

The British civilian medical profession of 1614 knew that it was the acidic principle of citrus fruit which was lacking, although they considered any acid acceptable when ascorbic acid (Vitamin C) was unavailable. In 1614 John Woodall (Surgeon General of the East India Company) published “The Surgion’s Mate” as a handbook for apprentice surgeons aboard the company’s ships. In it he described scurvy as resulting from a dietary deficiency. His recommendation for its cure was fresh food or, if not available, oranges, lemons, limes and tamarinds, or as a last resort, Oil of Vitriol (sulfuric acid).[6]

In 1734, the Leiden-based physician Johann Bachstrom published a book on scurvy in which he stated that “scurvy is solely owing to a total abstinence from fresh vegetable food, and greens; which is alone the primary cause of the disease.” and urged the use of fresh fruit and vegetables as a cure. In 1740, citrus juice (usually lemon or lime juice) was added to the recipe of the traditional daily ration of watered-down rum known as grog to cut down on the water’s foulness. Although they did not know the reason at the time, Admiral Edward Vernon’s sailors were healthier than the rest of the navy, due to the daily doses of vitamin C the sailors received.[7] However, it was not until 1747 that James Lind formally proved that scurvy could be treated and prevented by supplementing the diet with citrus fruit such as limes or lemons.[3]
