Known as Tai Zi Shen, Pseudostellaria, False starwort or Prince Seng, this plant is an adaptogen in the Caryophyllaceae family that is used in Chinese medicine and herbalism to tonify the qi and generate yin fluids. It is known as the "ginseng of the lungs". The plant is a low growing caryophyllaceae that is grown in Southern China in the provinces of Jiangsu, Anhui, Shandong, Heilongjiang, Jilin, Liaoning, Hebei, Henan, Shaanxi, Zhejiang, Jiangxi, Hubei, Shaanxi. and Shaanxi provinces. Botanically it is known as Pseudostellaria heterophylla (Miq.) Pax ex Pax et Hoffm.


Tai zi shen is a relatively recent addition to the Chung Yao Chi New Chinese Materia Medica, having been officially added in 1959, based upon local and ethnic use. [1] [2]It is weaker than Panax ginseng. The herb is a mild adaptogen, demulcent, an immune tonic, nutritive, and a pectoral herb. In Chinese terms it tonifies the yin. Accordingly the herb is restorative for lung damage due to excess heat or dryness including hot or dry asthma, pleurisy, bronchitis, bacterial pneumonia, wheezing, dry cough, and emphysema. Scientific research shows that Pseudostellaria aids in protecting the mucin layer that lines the respiratory tract and functions as an immune defense system. In the form Li Gan Zi Shen Tang (Regulate the Liver & Enrich the Kidneys Decoction) it is used to treat yin deficiency in diabetes mellitus[3]The polysaccharide fractions have anti-tumor properties. [4] A lectin in the roots is being studied for anti HIV purposes.[5]
