Nu Zhen Zi, commonly known as ligustrum fruit or glossy privet fruit, is a revered herb in Traditional Chinese Medicine (TCM), celebrated for its ability to nourish kidney and liver yin, support vision, and promote vitality.

Documented in ancient texts like the Shennong Bencao Jing (Divine Farmer’s Materia Medica), this time-honored herb has been a staple in TCM for centuries. Its cooling, nourishing properties reflect ancient wisdom, offering a natural solution for modern-day issues like premature aging, vision problems, and fatigue.
