Rosa Chinensis Viridiflora
Also known as: Chinese rose 'Viridiflora', Green rose, Rosa chinensis 'Viridiflora'
Overview
Rosa chinensis 'Viridiflora' is a unique cultivar of the Chinese rose, distinguished by its green, leaf-like flowers, a phenomenon known as phyllody. While the broader species, Rosa chinensis, has a history of traditional medicinal use and is known for its ornamental value, the 'Viridiflora' cultivar is primarily studied for its distinctive floral morphology and phytochemical composition. Research indicates that extracts from Rosa chinensis, including its cultivars, possess significant antioxidant properties, attributed to compounds like berberine and emodin. However, specific clinical research on 'Viridiflora' as a dietary supplement is very limited, with most evidence derived from in vitro and molecular studies. Its potential as a supplement is largely inferred from the antioxidant capacity observed in preclinical settings, rather than direct human trials.
Benefits
Research on *Rosa chinensis* extracts, from which 'Viridiflora' is derived, indicates strong antioxidant activity. In vitro studies have shown that *Rosa chinensis* extracts exhibit higher antioxidant potential compared to related species like *Rosa cymosa* and *Rosa indica*. This effect is primarily attributed to phytochemicals such as berberine and emodin, which have demonstrated significant binding affinity to antioxidant enzymes like superoxide dismutase (SOD), thereby helping to mitigate oxidative stress. While these findings suggest a potential benefit in conditions related to oxidative damage, it is crucial to note that there is no direct clinical evidence, human trials, or meta-analyses specifically validating the efficacy of *Rosa chinensis* 'Viridiflora' as a supplement in humans. All inferred benefits are based on preclinical data and the general antioxidant properties of the species.
How it works
The primary mechanism of action for *Rosa chinensis* 'Viridiflora' is believed to be its antioxidant activity. This is mediated by various phytochemicals, including berberine and emodin, which are present in *Rosa chinensis* extracts. These compounds are thought to scavenge free radicals, thereby reducing oxidative damage at the cellular level. Molecular docking studies have suggested that these phytochemicals can bind to and potentially enhance the activity of antioxidant enzymes such as superoxide dismutase (SOD). This interaction helps to neutralize harmful reactive oxygen species within the body. It's important to distinguish that the unique green flower phenotype of 'Viridiflora' is due to altered expression of floral development genes (e.g., RcAP1, RcAP2, RcAG) and does not directly contribute to its biological activity or human health benefits.
Side effects
Currently, there are no documented clinical safety data or reported adverse effects specifically associated with *Rosa chinensis* 'Viridiflora' when used as a supplement. Due to the lack of human clinical trials, a comprehensive safety profile has not been established. While other *Rosa* species have a history of traditional use and are generally considered safe, this cannot be directly extrapolated to 'Viridiflora' without specific research. There are no known drug interactions or contraindications documented in the scientific literature for this particular cultivar. Consumers should exercise caution and consult with a healthcare professional before using *Rosa chinensis* 'Viridiflora' as a supplement, especially if they have underlying health conditions or are taking other medications, as its safety in these contexts remains unverified.
Dosage
There are no established or clinically validated dosing guidelines for *Rosa chinensis* 'Viridiflora' as a supplement ingredient. This is primarily due to the absence of human clinical trials investigating its efficacy and safety. Traditional uses of *Rosa chinensis* extracts vary widely, but these do not provide standardized dosages for the 'Viridiflora' cultivar. Factors such as optimal administration routes, bioavailability, and appropriate dosages for specific health purposes remain unexplored in human studies. Without scientific evidence, any suggested dosage would be speculative and potentially unsafe. Therefore, it is not recommended to use this ingredient as a supplement until robust clinical research provides clear dosing recommendations and safety parameters.
FAQs
Is Rosa chinensis 'Viridiflora' effective as an antioxidant supplement?
Preclinical in vitro evidence suggests antioxidant potential, but there are no human clinical trials to confirm its efficacy as a supplement in humans.
Is it safe to consume Rosa chinensis 'Viridiflora'?
Its safety is presumed based on related *Rosa* species, but direct clinical confirmation for 'Viridiflora' as a supplement is lacking.
What are the active compounds in Rosa chinensis 'Viridiflora'?
Key phytochemicals contributing to its antioxidant effects include berberine, emodin, and limonene, among others.
Does the green flower phenotype affect the supplement's properties?
No, the green flower phenotype is a botanical characteristic related to floral gene expression and does not directly impact the supplement's bioactivity or health benefits.

- https://pmc.ncbi.nlm.nih.gov/articles/PMC12002594/ – This in vitro and in silico study compared the antioxidant activity of *Rosa chinensis* with other *Rosa* species. It found that *R. chinensis* exhibited the highest antioxidant activity and identified berberine and emodin as key compounds with strong binding affinity to superoxide dismutase (SOD), suggesting a mechanism for its antioxidant effects. The study provides robust preclinical evidence for antioxidant potential but lacks in vivo or clinical data.
- https://www.frontiersin.org/journals/plant-science/articles/10.3389/fpls.2016.00996/full – This molecular gene expression study investigated the genetic basis of the green flower phenotype in *Rosa chinensis* cv. Viridiflora. It identified specific gene expression changes underlying this unique morphology, focusing on plant development. While high quality for botanical genetics, its findings are not directly relevant to the supplement effects or human health benefits of the plant.
- https://pubmed.ncbi.nlm.nih.gov/27462328/ – This molecular biology study further explored the genetic mechanisms behind the phyllody (leaf-like floral organs) in *Rosa chinensis* cv. Viridiflora. It linked the down-regulation of specific floral organ identity genes to the characteristic green flower phenotype. The research contributes to understanding plant developmental biology but does not provide clinical or pharmacological data relevant to human supplementation.
