Scurvy grass is an herb. Its leaves and flowering parts are used to make medicine.
Scurvy grass gets its name from the fact that sailors used to take it to prevent a disease called scurvy. People get scurvy when they don't get enough vitamin C (vitamin C deficiency), which is found in citrus fruits. Scurvy was a frequent problem among sailors who couldn't get fresh fruit while at sea.
Scurvy grass (Cochlearia officinalis) is sometimes called watercress. Be careful not to confuse it with watercress (Nasturtium officinale). You can tell the difference because scurvy grass flowers have a strong fragrance and taste when they are rubbed.
How does it work?
Scurvy grass contains a high concentration of vitamin C. It may also be able to fight bacteria and act as a laxative.

Scurvy grass might have an effect like a water pill or "diuretic." Taking scurvy grass might decrease how well the body gets rid of lithium. This could increase how much lithium is in the body and result in serious side effects. Talk with your healthcare provider before using this product if you are taking lithium. Your lithium dose might need to be changed.
The appropriate dose of scurvy grass depends on several factors such as the user's age, health, and several other conditions.
