Chinese Privet (Ligustrum Lucidum, Nu Zhen Zi)

Glossy PrivetChinese privet tree is also known as glossy privet, ligustrum lucidum in scientific name, and Nu Zhen Zi in Pinyin. Sometimes it is a bit annoying when ligustrum lucidum berries are ripe. This is simply because the falling black fruits may spot your coat if you get too close to it. It is these unpleasant fruits that act as a terrific yin tonic. That’s to say, the medicinal part of this plant is the fruit, which is a top-grade Chinese herb for the treatment of erectile dysfunction, hair loss, tinnitus, dim eyesight, fatigue, neurasthenia, etc. And these health benefits have been well documented in the “Shen Nong’s Herbal Classic”. Besides of the medicinal uses, it is also cultivated as ornamental plant and bonsai tree as it has a very long flowering period and very beautiful flowers. Since it is used medicinally, try not to confuse it with Ligustrum sinense since they share the name Chinese privet.

      First of all, clinically two or more ingredients are often prescribed to treat chronic kidney disease; secondarily, according to different signs and symptoms the chronic kidney disease can be treated by different formulas, such as Zhi Bai Di Huang Wan, Zuo Gui Pian, Shen Qi Wan, You Gui Wan, Qi Ju Di Huang Wan, Ming Mu Di Huang Wan, and the like. So, they should be administered under the guidance of a doctor.

      In China there are many researches on cancer treatment with Huang Qi Nu Zhen Zi Tang (Ligustrum Lucidum and Astragalus Combination). For example, a paper, published in Tian Jin Zhong Yi Xue Yuan Xue Bao (Journal of Tianjin College of Traditional Chinese Medicine), 2001, Iss 3, confirmed that this formula could significantly inhibit nine kinds of cancer cells of stomach and colon digestive tract. And they also concluded that it made it perhaps by reducing the secretion of matrilysin.

    A friend sent me a 1 lb. bottle of what looked like seeds but that I now understand is the dried fruit of Ligustrum Licidum. There’s info on the label about it being a good liver & kidney tonic, helps with fatigue, low immune, tumor formation, insomnia, etc. The directions on the bottle say 5-10 grams, in 2 doses, on an empty stomach. Do I grind the seeds and make a tincture or oil in a Magic Butter machine or just grind the fruit and put it in a gelatin capsule.. Can I make a tea with just the ground up seeds? I really do not know what I am doing. I have CFS/ME with low immune system, fatigue and insomnia.

      Fresh Chinese privet is edible. The one bought from pharmacy is usually dried fruit. Since it produces little effect by making tea alone, it is often combined with other herbs. For example, Er Zi Ju Hua Yin is a formula for dry eye, dim vision, blurred vision, and loss of vision caused by Yin deficiency in liver and kidney. And it is composed of 15g Ligustrum lucidum, 15g Goji berry, and 10g chrysanthemum. As for chronic insomnia, it is often combined with Suan Zao Ren (Jujube Seed), Shi Lian Zi (Black Lotus Seed), Schizandra Berry (Wu Wei Zi), and amber. In short, usually it should be used together with other herbs to maximize its benefits according to your physical condition. Or, you can simply follow the directions.

    Please let me know what herb(s) are good for a Pituitary benign tumor. It has given me other complications (critically low libido and testosterone levels, high PSA prostate levels of 9, Hiatal Hernia, easy intestinal bleedings). I’m a male, late 40’s who maintains a healthy diet with fruits and veggies, don’t smoke, drink alcohol, etc.
    Thanks a lot.

    Hello, I recently just confirmed that I have a Ligustrum lucidum growing in my backyard. Upon researching it, I found many sites that said that the Berries are toxic. But then I stumbled upon a treasure trove of information saying that it has been used for thousands of years in TCM to treat rhuematism and immune dysfunction. Which obviously got my attention, as I have rheumatoid arthritis!

    Since some claim the betties to be toxic, I want to make sure I am preparing them properly so I can take advantage! Do you know of a place where I could find a “recipe” or instructions on preparation? I’m not sure if I should make a tea or an extract oil. I appreciate any direction you can provide.

    Thank you for writing this article. It was the best information I’ve found on this tree so far!

    Can Ligustrum Lucidum ornamental be purchased at say, a Home Depot or specialty plant nursery? Are there any health benefits in the leaves, roots? Or just the berries? Where may I find the shrub in its berry Stage? Thank you. Jim
