Chinese Dodder (Cuscuta chinensis) has been used in Traditional Chinese Medicine (TCM) for centuries, particularly to "tonify the Kidneys" and support reproductive health. In TCM theory, the "Kidneys" encompass not just the anatomical kidneys but also broader concepts related to vitality, sexual function, and longevity. Chinese Dodder seeds are believed to strengthen "Kidney yang," improve fertility, and support vision and liver health as well. These traditional uses are documented in classic TCM texts, and the herb is a common component of herbal formulas intended for conditions associated with "Kidney deficiency," such as fatigue, lower back pain, and sexual dysfunction.

Scientific research on Chinese Dodder's effects is limited and mostly preclinical. Some animal studies suggest that extracts may have antioxidant, immunomodulatory, and hormone-regulating properties, which could theoretically support the traditional use. However, robust clinical trials in humans directly validating its benefit to kidney health, as understood in Western medicine, are lacking. Therefore, its use for supporting the "Kidneys" is justified primarily by traditional evidence rather than strong scientific validation.
