Quick Summary

The genus Hizikia refers to a type of brown algae that is harvested from wild beds along rocky shores, particularly in Japan, Korea, and China. These seaweeds are often eaten with meat or fish and in soups.1

Algae, in general, are vital to ecosystems as they perform photosynthesis, converting carbon dioxide and water into organic food molecules using sunlight. They form the base of the food chain and produce a significant portion of the Earth's oxygen. Some algae can be harmful, producing toxins that can contaminate shellfish and finfish, rendering them poisonous to humans.12
