“咸” (xián) is a Chinese character that means "salty." It is commonly used to describe the taste of foods that contain salt, such as pickles or salted fish. In Chinese cuisine, the flavor of salt is essential for enhancing the overall taste of dishes. In addition to its culinary meaning, “咸” is also used in traditional Chinese medicine. It is associated with the Five Elements theory, where it corresponds to the Water element. This connection suggests that salty foods can have specific health benefits, such as promoting hydration and supporting kidney function.
