Cluster Fig (Ficus racemosa), also known as Gular or Udumbara, has a longstanding history of use in Ayurvedic and traditional medicine systems across India and Southeast Asia. In these traditions, various parts of the plant—including the bark, leaves, and fruit—are used for a variety of ailments, including edema (referred to traditionally as "shotha," or swelling). Classical Ayurvedic texts describe formulations containing Cluster Fig bark or decoctions as having diuretic and anti-inflammatory properties, which are believed to help reduce fluid retention and swelling.

While there is abundant traditional use, direct scientific studies specifically focusing on Cluster Fig's efficacy for edema in humans are limited. Some animal studies and pharmacological evaluations have indicated that extracts of Ficus racemosa may exhibit diuretic and anti-inflammatory effects, which could theoretically contribute to reducing edema. However, these findings are preliminary and not robustly confirmed in human clinical trials. Thus, while the traditional basis for its use is strong, current scientific validation is modest and indirect.

In summary, Cluster Fig is used traditionally to support the treatment of edema, primarily due to its reputed diuretic and anti-inflammatory actions. The evidence for this use comes predominantly from historical and ethnomedicinal sources, with only limited scientific corroboration at this time.
