Rating (out of 5): 2

Dodder (genus Cuscuta) has a long history of use in traditional medicine, particularly within Chinese herbal practice. In Traditional Chinese Medicine (TCM), dodder seed (Cuscuta chinensis or Cuscuta australis) is known as Tu Si Zi and has been used to support kidney and reproductive health, often prescribed for issues such as impotence, infertility, and frequent urination. Despite its frequent use in such contexts, robust scientific studies validating these uses are limited. Some in vitro and animal studies suggest that dodder seed extract may have antioxidant properties and influence hormone levels, which could theoretically affect reproductive function. However, these findings are preliminary, and well-conducted human clinical trials are lacking. Thus, while its use for the reproductive system is justified on a strong traditional basis—especially in East Asian herbal medicine—the level of scientific evidence for its efficacy in this domain is low. As such, most claims about dodder's benefits for reproductive health should be seen as rooted in tradition rather than modern research.
