The coastal path of The Lizard is swathed with white in the summer months. This is Scurvygrass, often found in association with its close cousin Danish or Early Scurvygrass (C. danica). Both are native to Britain, and can tolerate high levels of salt and salt spray, whether on the coastal cliff-edge or on roadside verges of the A30, where the Council salt-grits the road in times of frost and snow. Scurvygrass is one of those plants that has taken advantage of new niche habitats and has literally ‘taken to the roads’.
The biggest claim to fame of Scurvygrass is its past medicinal use in the treatment of scurvy. Sailors on long voyages used to suffer from this disease, caused by a lack of Vitamin C. Scurvygrass leaves are packed with Vitamin C, and was made into a concentrated solution for seafarers to help protect them. Captain Cook was a big supporter of its efficacy.

…The Befuddlement Draught made at Hogwart’s School of Witchcraft and Wizardry in the Harry Potter books was concocted from Scurvygrass, Lovage and Sneezewort.
