Conclusions
Focussing our attention on the mean value of 76.6% VC, it can be concluded that a minimum diet of 100 g of the sea fennel leaves per day provides a sufficient amount of vitamin C to meet the recommended daily allowance of 75 mg VC per person. Since for man, dehydroascorbic acid is as effective a vitamin as is ascorbic acid,Crithmum maritimum should be recognized as a suitable means of protection against scurvy, as it has long been recognized by sailors and fishermen.
According to Hegi (1906),Crithmum in former times was also used for the production of soda. Hegi further states that it may well serve in temperate climates for ornamental decoration in rock gardens close to the sea.
