Provence Rose (Rosa centifolia) has a long history of use in traditional medicine, primarily in Europe, the Middle East, and parts of Asia. Historically, various preparations of rose petals—such as infusions, teas, or topical applications—have been used for a variety of ailments, including mild diuretic purposes. The diuretic effect, which involves promoting urine production, is the main reason Provence Rose has been traditionally considered for conditions like edema (fluid retention). This use is based on observations and reports in herbal medicine texts rather than on rigorous scientific evaluations.

However, the evidence supporting the efficacy of Provence Rose for edema remains largely anecdotal. Only a few laboratory studies have investigated the diuretic potential of rose extracts, and these typically involve related species rather than Rosa centifolia specifically. Existing research is limited in scale, often performed in vitro or in animal models, and does not provide robust clinical support for its use in human edema. No high-quality clinical trials have demonstrated that Provence Rose is effective or safe for this purpose.

In summary, Provence Rose is used for edema based on traditional herbal practices, with little to no direct scientific validation. The evidence is weak, warranting a low evidence rating.
