Chinese Dodder (Cuscuta chinensis) has a long history of use in Traditional Chinese Medicine (TCM), particularly for conditions related to kidney health, reproductive function, and sexual vitality. In TCM, premature ejaculation is often associated with "kidney deficiency," and Chinese Dodder seeds (Tu Si Zi) are reputed to "tonify the kidney yang," improve sexual performance, and address related symptoms such as weak libido or premature ejaculation. Classical herbal texts and TCM formularies list Chinese Dodder as an ingredient in herbal blends intended for male sexual health, but these recommendations are rooted in centuries-old theoretical frameworks rather than modern scientific validation.

Scientifically, evidence supporting the use of Chinese Dodder for premature ejaculation is minimal. Some laboratory studies suggest that Cuscuta chinensis extracts may have antioxidative, neuroprotective, or hormone-modulating properties, but these findings are preliminary and not specific to sexual performance or ejaculatory control. There are no high-quality clinical trials demonstrating efficacy for premature ejaculation in humans. Consequently, the use of Chinese Dodder for this condition is primarily justified by traditional usage, with little to no direct modern scientific evidence to substantiate its effectiveness for premature ejaculation.
