A traditional Chinese herbal combination of polydatin and hawthorn flavonoids reduced atherosclerotic lesions by up to 72.99% in laboratory mice by protecting and restoring damaged mitochondria, the energy-producing structures inside cells. According to Gram Research analysis, the herbal mixture worked by increasing a protective protein called YTHDF2 while decreasing a harmful protein called DRP1 that fragments mitochondria. The treatment also lowered cholesterol and inflammatory markers in the bloodstream. However, these results come from animal and cell studies only, so human clinical trials are needed before this approach could become a medical treatment.
Researchers discovered that a traditional Chinese medicine combination of polydatin and hawthorn flavonoids may help prevent atherosclerosis, a condition where fatty deposits build up in arteries. According to Gram Research analysis, this herbal mixture worked by fixing damaged mitochondria, the tiny energy factories inside cells. In studies using mice and human cells, the treatment reduced atherosclerotic lesions by up to 73% at high doses and lowered harmful cholesterol levels. The findings suggest this natural approach could offer a new way to protect heart health, though human clinical trials are still needed to confirm these results.
Key Statistics
A 2026 research study found that a polydatin and hawthorn flavonoid combination reduced atherosclerotic lesions by 72.99% at the highest dose in mice fed a high-fat diet, compared to untreated controls.
In laboratory studies, the herbal combination increased the protective protein YTHDF2 while reducing the harmful protein DRP1 by 43.88% and 38.31% respectively, restoring normal mitochondrial structure in human blood vessel cells.
The herbal treatment lowered circulating total cholesterol, triglycerides, and LDL cholesterol while suppressing proinflammatory cytokines that contribute to atherosclerosis development in the animal model.
The Quick Take
- What they studied: Whether a combination of two plant compounds from traditional Chinese medicine could prevent atherosclerosis by protecting the energy-producing structures inside cells.
- Who participated: The research used laboratory mice genetically prone to heart disease that were fed a high-fat diet, plus human cells grown in dishes to mimic blood vessel damage.
- Key finding: The herbal combination reduced atherosclerotic lesions by 72.99% at the highest dose tested in mice, and also lowered cholesterol and inflammation markers in the bloodstream.
- What it means for you: This research suggests a natural herbal approach might help prevent heart disease by keeping cells healthy, but these results are from lab and animal studies only. Human trials would be needed before this could become a medical treatment.
The Research Details
Scientists created a laboratory model of atherosclerosis using mice that were genetically modified to develop heart disease when eating a high-fat diet. They gave some mice the herbal combination at different doses while others received no treatment. The researchers measured how much plaque built up in the arteries and checked blood cholesterol levels. They also studied human blood vessel cells in dishes, exposing them to oxidized cholesterol (a harmful form) and then treating them with the herbal mixture to see if it protected the cells.
To understand exactly how the treatment worked, the scientists used advanced genetic techniques to turn off specific genes in the cells. This helped them identify which molecular pathways were responsible for the protective effects. They measured changes in mitochondria, the energy-producing structures inside cells, using specialized imaging and genetic analysis.
This multi-layered approach, combining animal models with cell studies and genetic manipulation, allowed researchers to trace the complete pathway from the herbal compounds all the way down to the molecular mechanisms that prevent heart disease.
Understanding how natural compounds work at the molecular level helps scientists develop better treatments for atherosclerosis. By identifying the specific cellular pathways involved, researchers can create more targeted therapies and potentially combine treatments more effectively. This research bridges traditional medicine knowledge with modern molecular biology.
The study used multiple complementary approaches, including animal models, human cell cultures, and genetic manipulation techniques, which strengthens confidence in the findings. The dose-dependent response (higher doses produced stronger effects) suggests a real biological effect rather than random chance. However, this is laboratory research, not human clinical trials, so results may not directly translate to people. The study was published in a peer-reviewed journal, indicating expert evaluation of the methods.
What the Results Show
The herbal combination produced strong dose-dependent protective effects in mice with atherosclerosis. At low doses, it reduced atherosclerotic lesions by 44.8%. At medium doses, the reduction increased to 49.29%. At the highest dose, the reduction reached 72.99%, meaning nearly three-quarters of the plaque buildup was prevented. These results suggest the treatment works better at higher concentrations.
The herbal mixture also improved blood chemistry markers. It lowered total cholesterol, triglycerides, and harmful LDL cholesterol while reducing very-low-density lipoprotein levels. Additionally, the treatment suppressed inflammatory molecules that contribute to heart disease. These improvements in blood chemistry likely contributed to the reduction in plaque formation.
At the cellular level, the herbal combination rescued damaged mitochondria in blood vessel cells. Mitochondria are the energy factories of cells, and when they become fragmented and dysfunctional, they contribute to atherosclerosis. The treatment restored normal mitochondrial structure, increased the length of mitochondria, improved their shape, and boosted the amount of mitochondrial DNA, indicating healthier, more functional energy-producing structures.
The research identified the specific molecular mechanism behind the protective effects. The herbal combination worked by increasing a protein called YTHDF2 while decreasing a protein called DRP1. DRP1 is responsible for breaking apart mitochondria into smaller pieces, a process called fragmentation. When DRP1 is overactive, mitochondria become damaged and dysfunctional. By suppressing DRP1, the herbal mixture prevented this harmful fragmentation. The study also found that YTHDF2 and DRP1 work in opposition to each other, forming a regulatory system that controls mitochondrial health.
This research extends previous knowledge about how traditional Chinese medicine compounds affect heart health. While earlier studies suggested these plant compounds had protective effects, this work identifies the specific cellular mechanism involved. The focus on mitochondrial health represents a newer understanding of how atherosclerosis develops and progresses. The findings align with emerging research showing that mitochondrial dysfunction plays a central role in cardiovascular disease.
This study used laboratory mice and human cells grown in dishes, not living human subjects. Results from animal models do not always translate directly to humans due to differences in metabolism and physiology. The research does not include clinical trials in people, so the safety and effectiveness in actual patients remains unknown. The study examined one specific herbal combination, so results may not apply to individual components used separately. Long-term effects and optimal dosing for human use have not been established. Additionally, the sample size for animal studies was not specified in the abstract, making it difficult to assess statistical power.
The Bottom Line
Based on this research, the herbal combination shows promise as a potential preventive approach for atherosclerosis, but it is not yet ready for medical use. The evidence is strong for laboratory and animal studies (confidence level: moderate for basic science), but human clinical trials are essential before recommending this as a treatment. People interested in heart health should continue following established medical advice: maintain a healthy diet, exercise regularly, manage stress, and work with healthcare providers on cholesterol management.
This research is most relevant to cardiovascular researchers, traditional medicine practitioners, and pharmaceutical companies developing new heart disease treatments. People with high cholesterol, family history of heart disease, or existing atherosclerosis may find this research interesting, but should not change their medical treatment based on these findings alone. Healthcare providers should monitor this research as it progresses toward human trials.
Laboratory research typically takes 5 to 10 years to progress from initial discovery to human clinical trials. If this herbal combination moves forward in development, it would likely take several years of additional testing before becoming available as a medical treatment. People should not expect immediate availability of this treatment.
Frequently Asked Questions
Can I take polydatin and hawthorn flavonoids now to prevent heart disease?
Not yet based on this research. While laboratory studies show promise, human clinical trials have not been conducted. Talk to your doctor about proven heart disease prevention strategies like diet, exercise, and cholesterol management.
How do mitochondria relate to atherosclerosis and heart disease?
Mitochondria are cells’ energy factories. When they become fragmented and dysfunctional, they contribute to inflammation and damage in blood vessel walls, promoting atherosclerosis. Protecting mitochondrial health may help prevent heart disease.
What is the YTHDF2-DRP1 axis mentioned in this research?
This is a cellular control system where YTHDF2 and DRP1 proteins work in opposition. YTHDF2 acts as a brake on DRP1, which normally fragments mitochondria. The herbal combination strengthens this brake, keeping mitochondria intact and healthy.
How long until this herbal treatment becomes available as a medicine?
Laboratory research typically requires 5 to 10 additional years before human clinical trials begin. If trials are successful, regulatory approval could take several more years. This treatment is not yet available for medical use.
Does this research apply to people who already have atherosclerosis?
This study used mice and cells, not people with existing heart disease. Whether the herbal combination helps people with established atherosclerosis remains unknown. Consult your cardiologist about proven treatments for existing atherosclerosis.
