Rosa laevigata (Cherokee rose) has a long history of use in traditional Chinese medicine (TCM). Its fruits, known as Jin Ying Zi (金樱子), are mainly used to secure essence and reduce urination, treat diarrhea, and support the kidney and bladder. In TCM texts, Rosa laevigata is sometimes included in formulas aimed at reducing "dampness" or "edema," though it is not a primary herb for this indication. The rationale for its use often connects to its astringent properties, which are thought to help "contain" fluids and prevent excessive leakage. However, direct references to its use solely or primarily for treating edema (fluid retention) are limited and usually occur in combination with other herbs specifically targeting edema.

Scientific research investigating Rosa laevigata for edema is minimal. A few pharmacological studies have explored its antioxidant and anti-inflammatory properties, and some animal studies suggest diuretic effects, but these are not robust or directly tied to clinical edema. There is a lack of modern, high-quality clinical trials supporting its efficacy for this condition.

In summary, the use of Rosa laevigata for edema is primarily based on traditional practice rather than scientific validation, and the evidence supporting its use is limited and mostly anecdotal or theoretical within the TCM framework.
