A plant extract called Prosopis farcta reduced cholesterol, triglycerides, and harmful LDL cholesterol in rats as effectively as the prescription drug atorvastatin, according to a 2026 animal study of 49 rats. The extract also increased protective HDL cholesterol and a heart-protective protein called PON-1. However, another plant tested, Scrophularia striata, paradoxically worsened cholesterol levels and artery damage. These findings suggest Prosopis farcta warrants further investigation as a potential natural alternative for cholesterol management, but human clinical trials are essential before any medical use.
Researchers tested two plant-based extracts against a common cholesterol medication in rats with high cholesterol. One plant, called Prosopis farcta, worked just as well as the drug atorvastatin at lowering cholesterol and reducing artery damage. The other plant, Scrophularia striata, actually made things worse. According to Gram Research analysis, these findings suggest that certain plants might offer a safer alternative to prescription cholesterol drugs, though human studies are still needed to confirm the results.
Key Statistics
A 2026 animal study of 49 rats found that Prosopis farcta extract at 50 mg per kilogram of body weight reduced total cholesterol, triglycerides, and LDL cholesterol by significant amounts while increasing protective HDL cholesterol, matching the effectiveness of the prescription drug atorvastatin.
In the same 2026 study, Prosopis farcta extract increased PON-1, a protective protein that helps prevent artery damage, by a statistically significant amount compared to rats fed a high-cholesterol diet alone.
The 2026 research found that Scrophularia striata extract at both tested doses (100 and 500 mg per kilogram) paradoxically increased triglycerides and worsened microscopic damage to artery walls in rats with high cholesterol.
Prosopis farcta extract reduced oxidized LDL, a particularly harmful form of cholesterol that triggers inflammation and plaque buildup in arteries, by a statistically significant margin in the 2026 rat study.
The Quick Take
- What they studied: Whether two traditional medicinal plants could lower cholesterol and prevent artery damage as effectively as a popular prescription drug called atorvastatin.
- Who participated: 49 male laboratory rats weighing 250 to 280 grams, divided into seven groups. Some ate a normal diet, others ate a high-cholesterol diet, and some received plant extracts or the drug atorvastatin.
- Key finding: Prosopis farcta extract at the lower dose (50 mg per kilogram of body weight) reduced cholesterol, triglycerides, and harmful LDL cholesterol by significant amounts and worked about as well as atorvastatin. Scrophularia striata, however, actually increased triglycerides and worsened artery damage.
- What it means for you: One plant extract showed promise as a potential natural alternative to cholesterol medications, but these are early results from animal studies. Human clinical trials are necessary before anyone should consider using these plants instead of prescribed medications. Talk to your doctor before making any changes to cholesterol treatment.
The Research Details
Scientists fed 49 laboratory rats a high-cholesterol diet for nine weeks to mimic the artery damage that happens in people with high cholesterol. Then they divided the rats into groups and gave some of them either a prescription cholesterol drug (atorvastatin), extracts from Prosopis farcta at two different doses, or extracts from Scrophularia striata at two different doses. The remaining rats continued eating a normal diet as a control group. After six more weeks of treatment, the researchers measured cholesterol levels, triglycerides, and other markers of heart health in the rats’ blood. They also examined the rats’ arteries under a microscope to see how much damage had occurred.
This type of study is called a preclinical or animal model study. Researchers use it to test whether a treatment might work before trying it in humans. The advantage is that scientists can carefully control everything the animals eat and measure exact doses. The disadvantage is that results in rats don’t always translate to humans because our bodies work differently.
The researchers chose these two plants because they contain flavonoids, which are natural compounds found in plants that have anti-inflammatory and antioxidant properties. Both plants have been used in traditional medicine for heart problems, but no one had directly compared them to a modern cholesterol drug.
This research matters because current cholesterol medications like atorvastatin work well but can cause side effects in some people, including muscle pain and liver problems. If a plant extract could work just as well without these side effects, it could help millions of people manage their cholesterol more safely. However, testing in animals first is essential before trying anything in humans, so this study is an important early step.
This study was published in a peer-reviewed scientific journal, meaning other experts reviewed it before publication. The researchers used a clear experimental design with control groups, which is good scientific practice. However, the study only involved 49 rats divided into seven groups, so each group was relatively small. The most important limitation is that this is an animal study, not a human study. Rats’ bodies process substances differently than human bodies, so results may not apply to people. The researchers themselves noted that human clinical trials are needed to confirm whether these findings would work in actual patients.
What the Results Show
Prosopis farcta extract at the 50 mg per kilogram dose produced dramatic improvements in cholesterol markers. Total cholesterol dropped significantly, triglycerides (another type of blood fat) decreased substantially, and LDL cholesterol (the harmful kind) fell by a large amount. At the same time, HDL cholesterol (the protective kind) increased, and a protective protein called PON-1 increased significantly. These improvements were comparable to what the prescription drug atorvastatin achieved.
The extract also reduced oxidized LDL, which is particularly damaging to arteries because it triggers inflammation and plaque buildup. This suggests that Prosopis farcta works through multiple mechanisms to protect heart health, not just by lowering cholesterol numbers.
In stark contrast, Scrophularia striata produced the opposite effect. Both doses tested (100 and 500 mg per kilogram) actually increased triglycerides and worsened the microscopic damage visible in the rats’ arteries. This unexpected harmful effect suggests that while the plant contains beneficial compounds, something in it may act as a pro-oxidant at higher doses, meaning it creates harmful oxidative stress rather than preventing it.
The study measured several other markers of heart health beyond basic cholesterol. Adiponectin and SFRP5 are proteins that help regulate metabolism and inflammation. The high-cholesterol diet decreased these protective proteins, but Prosopis farcta extract restored them toward normal levels. This suggests the plant works by addressing multiple pathways involved in atherosclerosis, not just cholesterol levels. The microscopic examination of artery tissue showed that Prosopis farcta reduced the buildup of plaque and inflammatory cells in the artery walls, while Scrophularia striata increased these harmful changes.
This is one of the first studies to directly compare these two plant extracts against each other and against a modern prescription drug in the same experiment. Previous research had suggested that flavonoid-rich plants might help with heart health, but this study provides more concrete evidence for Prosopis farcta specifically. The finding that Scrophularia striata worsened outcomes is surprising and contradicts its traditional use for heart problems, suggesting that traditional use doesn’t always predict modern scientific results. The comparable effectiveness of Prosopis farcta to atorvastatin is noteworthy because it suggests natural compounds can match pharmaceutical drugs in animal models.
The biggest limitation is that this study used rats, not humans. Rats have different metabolisms, lifespans, and body systems, so results may not translate directly to people. The study also only lasted 15 weeks total, while atherosclerosis develops over years or decades in humans. The sample size of seven rats per group is relatively small, which means results could be due to chance variation. The study didn’t test the plant extracts in humans or even in larger animals like primates. Additionally, the researchers didn’t investigate exactly which compounds in Prosopis farcta were responsible for the benefits, so we don’t know if the whole plant extract is necessary or if specific ingredients could be isolated. Finally, the study didn’t examine potential side effects or toxicity of long-term use of these plant extracts.
The Bottom Line
Based on this animal study, Prosopis farcta extract shows promise as a potential treatment for high cholesterol and atherosclerosis. However, confidence in this recommendation is low because it comes from rat studies only. No one should use this plant extract instead of prescribed cholesterol medications without consulting their doctor. If human clinical trials confirm these results, Prosopis farcta might become a useful option for people who cannot tolerate standard medications or prefer natural alternatives. Scrophularia striata should not be used for cholesterol management based on these findings, as it appeared to worsen the condition.
People with high cholesterol or atherosclerosis should be aware of this research, but it’s too early to change treatment based on it. Researchers studying natural compounds for heart disease should pay attention to these results. Pharmaceutical companies might be interested in isolating and testing the active compounds from Prosopis farcta. People in regions where Prosopis farcta grows traditionally should not self-treat with it based on these preliminary results. Anyone currently taking cholesterol medications should continue them as prescribed and discuss any interest in plant-based alternatives with their doctor.
In the rat study, improvements in cholesterol markers appeared after six weeks of treatment. If similar results occur in humans, people might expect to see changes in blood work within four to eight weeks, though this is speculative. However, improvements in actual artery damage would take much longer to measure. Any human trials would need to run for months or years to determine if the plant extract actually prevents heart attacks and strokes, which is the ultimate goal of cholesterol treatment.
Frequently Asked Questions
Can I use Prosopis farcta extract instead of my cholesterol medication?
Not yet. This is an early animal study showing promise, but human clinical trials are needed first. Continue taking prescribed cholesterol medications and discuss any interest in plant-based alternatives with your doctor before making changes.
What is Prosopis farcta and where can I find it?
Prosopis farcta is a plant traditionally used in Middle Eastern and Asian medicine. It’s not widely available in most Western countries as a supplement. Even if you find it, the 2026 study was conducted in controlled laboratory conditions, so commercial products may differ significantly.
Why did Scrophularia striata make cholesterol worse in the study?
The researchers believe that at higher doses, Scrophularia striata may create harmful oxidative stress rather than preventing it. This shows that traditional use of a plant doesn’t guarantee modern scientific effectiveness, and dose matters significantly.
How long would it take to see cholesterol improvements from Prosopis farcta?
In the rat study, improvements appeared after six weeks of treatment. If results translate to humans, similar timeframes might apply, but this is speculative. Only human clinical trials can determine actual timelines for people.
Is this study proof that plant extracts work as well as cholesterol drugs?
No. This is preliminary evidence from rats only. Animal studies often don’t translate to humans because our bodies work differently. Multiple human clinical trials would be needed to confirm whether Prosopis farcta actually works in people and is safe for long-term use.
