With a sweet flavor and neutral nature, Lycium barbarum (goji berry) enters the liver and kidney meridians. Renowned since ancient times for its ability to “nourish Yin, benefit the kidneys, support the liver, and brighten the eyes,” goji berry has been a favored tonic among health luminaries such as Tao Hongjing and Sun Simiao. Its vivid red color—reminiscent of fresh blood—symbolizes vitality, and its sweet taste reinforces its nourishing properties. As described in the Ben Cao Zheng, goji berry’s robust, pure flavor allows it to replenish Yin without causing depletion, and countless classical texts extol its remarkable benefits.
