Rating (out of 5): 2

Saponins have been used in traditional medicine systems, such as Traditional Chinese Medicine and Ayurveda, to address conditions that may include edema (fluid retention or swelling). These uses are largely based on the perceived diuretic properties of certain plants rich in saponins. For example, herbs like Glycyrrhiza glabra (licorice) and Panax ginseng contain significant amounts of saponins and have been traditionally used to promote urination and reduce swelling. However, these historical uses are not based on controlled clinical studies, but rather on empirical observations and traditional beliefs.

Scientific evidence supporting the efficacy of saponins in treating or supporting edema is limited and mostly preclinical. Some in vitro and animal studies suggest that saponins may have diuretic effects or influence vascular permeability, which could theoretically impact fluid balance. However, high-quality human clinical trials are lacking, and there is no consensus in the scientific community regarding the routine use of saponins for edema. Thus, while there is a clear traditional basis for their use in this context, robust scientific validation is absent, and any recommendations for saponins in the management of edema remain rooted in tradition rather than modern evidence.
