Rugose Rose (Rosa rugosa), also known as Japanese rose, has a history of use in traditional East Asian medicine, particularly within Chinese and Korean herbal practices. In traditional Chinese medicine (TCM), the fruit of Rugose Rose (often called rosehip) is categorized as "Jin Ying Zi" and is primarily used to stabilize and bind, particularly for conditions related to the urinary and reproductive systems such as frequent urination and seminal emission. There are sparse references in TCM texts to its diuretic effects, which could be loosely linked to the relief of edema (fluid retention), as diuretics can sometimes be used to manage swelling. However, these uses are not direct or central to Rugose Rose’s traditional indications.

Scientifically, there is minimal evidence supporting Rugose Rose or its extracts for the treatment of edema. Most available research focuses on its antioxidant, anti-inflammatory, and potential anti-diabetic properties. There are no robust clinical trials or pharmacological studies that specifically examine its efficacy for edema or fluid retention in humans. Any use for this purpose is therefore rooted in tradition rather than validated by modern science, and the traditional support is itself limited and indirect.

In summary, the use of Rugose Rose for edema is primarily based on limited traditional notions of diuretic action, with little direct historical emphasis and no scientific validation.
