Health benefits of sea kale include its ability to regulate hormonal activity in the body, maintain kidney's health, boost the immune system.
The scientific name of sea kale is Crambe maritima and it grows wild around the coasts of Europe, stretching from the Atlantic Ocean to the Black Sea. It is a small shrub that grows well in very salty soil, and its young, fleshy, white roots are harvested. The leaves of sea kale are also used as salad greens in many cultures. It should be consumed quickly after harvesting, but the heart of the plant should not be damaged, as it can live for a number of years and continually produce vegetative fruit.
