Lá mọc đối, bóng, mép nguyên; chùy hoa trắng đầu cành, quả oval/thận chín đen tím có phấn. Dược liệu nhỏ, nhăn, vỏ mỏng quanh hạt có nội quả bì gỗ. Khác Câu kỷ tử đỏ, Đại táo đỏ nâu và nhiều quả cây cảnh. Cần phân biệt Ligustrum lucidum với Ligustrum sinense; không xác định bằng tên privet chung. Nu Zhen Zi is the mature fruit of Ligustrum lucidum, an evergreen shrub or tree often planted ornamentally. Its glossy opposite leaves and winter fruit clusters help a learner recognize the living plant, yet ornamental berries are not automatically safe or drug-grade. Several Ligustrum species occur in landscapes, and birds eating fruit does not establish human food safety. The source notes winter harvest but gives no universal seed-to-fruit age; a garden plant that bears berries does not meet materia standards by appearance alone. Traditional descriptions about liver, kidney, vision, or hair remain within a historical framework and do not prove treatment. No sufficiently verified formula or toxic pair was identified for this entry, so the page does not invent a combination or ratio. If handling a specimen, record species, fruit maturity, growing site, possible pesticide exposure, and whether the material was commercially tested. Do not eat wild or ornamental berries, grind them into a home product, or combine concentrated products with liver or hormone medicines without professional review. A winter berry cluster can make Ligustrum look like a food plant, but a botanical garden label does not establish edibility or a medicinal standard. Record the exact species and avoid tasting ornamental fruit. The accepted material is mature fruit, not leaf or bark, and its source should be traceable. Since the reviewed record did not verify a formula or toxic partner, the page leaves that blank rather than borrowing a recipe from another Ligustrum species. This is important when a shrub is common in landscaping: availability is not evidence of safety or quality. Common privet is widely planted in cities, but ornamental use can involve unknown pesticide exposure and several Ligustrum species. A winter fruit cluster should be treated as a recognition cue, not an invitation to pick and eat berries. The materia profile therefore emphasizes species confirmation, source, and a clear separation from culinary fruit.
