  • Salicornia herbacea is an annual herb growing in salt marshes and on muddy seashores. Salicornia herbacea has been used as a fork medicine as well as a seasoned vegetable. In fork medicine, Salicornia herbacea has been used to treat a variety of diseases such as constipation, obesity, diabetes, asthma, arthritis and cancer. However, the biological mechanisms for these activities have not been characterized, nor the active components. The immunomodulatory activity of Salicornia herbacea components were studied in the present study. The components of Salicornia herbacea were prepared from the whole plant by passage through a fine screen, and then dialyzed against PBS overnight. Immunomodulatory activities of the Salicornia herbacea components were examined on a mouse macrophage cell line, RAW 264.7 cells. The Salicornia herbacea components were shown to stimulate cytokine production, nitric oxide release, and expression of surface molecules in a dose dependent manner. The Salicornia herbacea components also induced further differentiation of slightly adherent RAW 264.7 cell into strongly adherent macrophages. These results indicate that Salicornia herbacea contains immunomodulator(s) that induces activation of macrophages.
