Hijiki
Hijiki is a porous, black seaweed with a surface that is less viscous but with more texture than other seaweeds. It is normally sold dried and should be reconstituted with water before use. Hijiki contains a lot of calcium, which can reduce nervousness and anxiety, and fibre, which is helpful for treating bowel disorders. It also contains a high level of iron, which is ideal for those who suffer from anaemia. As iron is absorbed by the body more easily when combined with Vitamin C, hijiki is best consumed with other vegetables.
