The seeds are known as nu zhen zi (female chastity seed/berry) in traditional Chinese medicine and are believed to nourish liver and kidney yin and jing in the treatment of tinnitus (ringing in the ears), vertigo (dizziness), premature graying of the hair, and soreness/weakness of the lower back and knees.[13][14] Due to the belief in the berries' ability to nourish the liver, they are also used in the treatment of disorders of the eye involving red or dry eyes, blurred vision, and pain.[15]
