Rosa Roxburghii Fruit Extract

Also known as: Rosa roxburghii, Chinese rose, guangyujin, *Rosa roxburghii*

Overview

Rosa roxburghii, commonly known as the Chinese rose, is a plant species native to China. The fruit of this plant is utilized to create extracts that are believed to offer various health benefits, primarily due to its rich composition of polyphenols and other bioactive compounds. Traditionally regarded for its medicinal properties, *Rosa roxburghii* is emerging in research, particularly focusing on its antioxidant capacity and anti-inflammatory effects. While studies suggest potential therapeutic applications, such as reducing inflammation and enhancing antioxidant status, rigorous clinical trials in humans remain necessary to validate these benefits fully. The extract is often consumed in supplement form, and its properties may vary based on preparation methods.

Benefits

Research indicates several potential benefits associated with *Rosa roxburghii* extract. Notably, it exhibits significant antioxidant capacity, as evidenced by a study where supplementation led to increased plasma antioxidant levels and improved glutathione redox state in healthy adults. Additionally, *Rosa roxburghii* has shown promise in alleviating symptoms related to ulcerative colitis by modulating gut microbiota and reducing inflammation in animal models. Some evidence also suggests potential effects on regulating blood lipid levels. However, despite these findings, specific effect sizes and clinical significance in human populations are not yet thoroughly documented, necessitating further investigation.

How it works

*Rosa roxburghii* works primarily through its antioxidant and anti-inflammatory properties. It interacts with antioxidant pathways in the body, potentially enhancing the activity of antioxidant enzymes. Additionally, it may modulate gut microbiota and reduce inflammation through pathways such as IL-17 signaling. However, its mechanisms are not fully elucidated, and the bioavailability and absorption characteristics of the extract require more comprehensive research.

Side effects

The safety profile for *Rosa roxburghii* is generally considered favorable based on traditional use, yet comprehensive safety data in humans are still limited. Common side effects have not been well-documented, and there are no known serious adverse effects reported in the literature to date. Conversely, potential interactions with other medications or specific contraindications are not established, indicating a need for caution, especially among pregnant or breastfeeding women, who should consult healthcare providers due to insufficient data. Overall, while acceptable safety has been inferred, thorough investigations into side effects and interactions are warranted.

Dosage

The optimal dosage of *Rosa roxburghii* extract has not been clearly defined, with a minimum effective dose also not established. Typical forms include extracts taken in supplement form, but specific recommendations concerning timing and dosage remain vague in the literature. Due to the lack of comprehensive studies on absorption and effects, precise dosing guidelines cannot be established; thus, users should approach with consideration of individual health conditions and consult a healthcare professional for personalized advice. The upper limits and safety thresholds are yet to be determined.
