Chinese Chive (Allium tuberosum) has a long history of use in Traditional Chinese Medicine (TCM), where it is known as "Jiu Cai." TCM practitioners have historically employed Chinese Chive seeds, sometimes called "Jiu Cai Zi," for various health conditions, particularly those related to the kidneys. The seeds are included in some herbal formulas intended to "tonify kidney yang," which is believed in TCM theory to support kidney function and address related symptoms such as lower back pain or urinary issues. However, the connection between Chinese Chive and nephritis (kidney inflammation) is primarily based on these traditional uses rather than modern clinical studies.

There is little to no robust scientific evidence directly validating the use of Chinese Chive or its seeds for the treatment of nephritis. While some laboratory studies have explored antioxidant and anti-inflammatory properties of Allium species in general, there is no published clinical research specifically supporting Chinese Chive for nephritis. Thus, its use for this condition remains rooted in traditional herbal practice, rather than being substantiated by modern scientific validation.
