Disclosed herein is a salt substitute obtained from a Salicornia species. The salt substitute has a high content of phyto-organic minerals from a Salicornia species and low sodium content, which are beneficial to the health of humans. The salt substitute also contains minerals, such as potassium or magnesium, which facilitate sodium excretion from the body and thus reduce the harmful effects of sodium accumulated in the body. Further, the salt substitute has a mineral balance created by the plant's innate metabolism and tastes salty enough for use as a substitute for table salt, and contains organic nutrients including amino acids, which are nutritionally beneficial and reduce the bitterness of minerals present in large amounts, thereby providing a good taste.
