海藻

海藻 (hǎi zǎo) refers to seaweed, a type of marine plant that grows in saltwater environments. It is distinct from freshwater algae and is commonly used in culinary and medicinal contexts.

The character 海 (hǎi) means 'sea' or 'ocean,' while 藻 (zǎo) refers to aquatic plants or algae. Together, they literally translate to 'sea plant,' emphasizing their origin in the ocean.

Seaweed is widely used in East Asian cuisines, especially in Japanese, Korean, and Chinese dishes. It is valued for its nutritional content and unique flavor. In traditional Chinese medicine, certain types of seaweed are believed to have health benefits, such as supporting thyroid function.
