Curcuminoids, the active polyphenolic compounds found in turmeric (Curcuma longa), have been investigated in a limited number of preclinical and clinical studies for their anti-inflammatory and antioxidant properties, which are relevant to the management of edema. Edema, characterized by the accumulation of fluid in tissues, is often associated with inflammation. Curcuminoids have demonstrated the ability to inhibit inflammatory mediators such as TNF-α, IL-1β, and COX-2 in laboratory and animal studies. Several animal models of inflammation-induced edema, such as carrageenan-induced paw edema in rats, have shown that curcumin administration can significantly reduce swelling, comparable to some standard anti-inflammatory drugs.

However, human clinical evidence specifically evaluating curcuminoids for the treatment of generalized edema is scarce. Most clinical studies have focused on related conditions involving inflammation, such as arthritis, rather than edema per se. Some small-scale clinical trials have reported a reduction in postoperative edema (e.g., after dental surgery) with curcumin supplementation, but these are limited in scope and quality. There is insufficient large-scale, high-quality clinical evidence to firmly establish curcuminoids as a standard treatment for edema. Thus, while there is preliminary scientific rationale and some supporting data, the evidence base is weak and primarily preclinical.
