Liver protection via oregano extractProtective effects of Origanum vulgare ethanol extract against cyclophosphamide-induced liver toxicity in mice.
Direct evidence of oregano's benefits
We evaluated the protective effects of oregano (Origanum vulgare) on liver toxicity induced by cyclophosphamide, a commonly used chemotherapy drug known for its potential liver damage. In our study, we pre-treated mice with various doses of oregano extract for seven days before administering a chemotherapy dose.
After 24 hours, we collected blood samples and liver tissues from the animals to assess the liver's response. The results were promising: we found that serum markers indicating liver damage, such as ALT, AST, and ALP, were significantly elevated in the mice treated with cyclophosphamide alone. However, those receiving oregano extract showed a marked reduction in these markers, suggesting that oregano may help protect the liver from poisoning caused by chemotherapy.
The histological examinations aligned with these findings and confirmed that oregano extract has protective properties against liver damage. With its rich array of flavonoids and phenolic compounds, oregano seems capable of supporting liver health during challenging treatments. Thus, incorporating oregano may offer a supportive approach to mitigate the side effects of chemotherapy on the liver.

Oregano protects liver healthHepatoprotective effect of Origanum vulgare in Wistar rats against carbon tetrachloride-induced hepatotoxicity.
Study highlights oregano's effectiveness
In our exploration of oregano's beneficial effects on liver health, we conducted a study on Wistar rats to assess how an extract from Origanum vulgare could shield against liver damage caused by carbon tetrachloride (CCl4). The experiment was structured with various groups of rats: a control group, a group receiving only the oregano extract, and others treated with CCl4 alongside different doses of oregano over 15 days.
Throughout the study, we measured key indicators of liver function, including enzymes in the serum, the levels of lipid peroxides, and antioxidant markers in liver tissues. We found that CCl4 led to clear signs of liver injury, but the administration of oregano extract showed significant protective effects. This improvement was most pronounced at the highest dose of 150 mg/kg.
Our analyses revealed that oregano not only helped in reducing liver enzyme levels indicative of damage but also boosted antioxidant activity in the liver. Histopathological examinations aligned with these biochemical improvements, indicating healthier liver cells after treatment with oregano. This study suggests that oregano could be a valuable ally in protecting against liver toxicity.

Oregano extract improves liver healthEthyl acetate fraction of oregano seed protects non-alcoholic fatty liver in high-fat diet-induced obese mice through modulation of .
High relevance to liver disease
We evaluated how oregano seed extract, specifically its ethyl acetate fraction, affects liver health in mice that were fed a high-fat diet. Over a period of 10 weeks, we found that when these mice were given 100 mg/kg of oregano seed extract alongside their high-fat diet, their weight and various liver enzyme levels significantly improved.
Remarkably, we observed a reduction in harmful substances like cholesterol and triglycerides, alongside an increase in beneficial high-density lipoprotein. This indicates a positive shift in the mice's overall liver health. Additionally, the fat accumulation in the liver decreased notably, which is a key factor in non-alcoholic fatty liver disease.
Furthermore, we examined the expression of certain genes related to fat metabolism and discovered that their activity went down significantly in the mice that received oregano treatment. This suggests that oregano may help regulate how the body processes fats, potentially leading to better management of obesity and fat-related liver issues.

Oregano may protect liver healthImpacts of intake of trichothecenes (Fusarium sporotrichioides) for dairy calves: Effects on animal growth, oxidative and inflammatory response.
Oregano's impact on liver disease.
We explored the impact of essential oils, specifically oregano, on liver health in dairy calves affected by trichothecenes from Fusarium sporotrichioides. In this study, we divided twelve calves into two groups: one receiving a blend of essential oils (including oregano) and the other as a control. Over 40 days, we monitored their growth, blood health, and overall wellness while ensuring both groups consumed feed contaminated with trichothecenes.
The calves that received essential oils showed a positive trend in body weight compared to the control group. We observed notable improvements in their blood parameters, including higher leukocyte counts and lower levels of certain liver enzymes, suggesting that oregano may help reduce liver stress. This group also exhibited lower oxidative stress markers and reduced inflammation as indicated by lower serum levels of haptoglobin and C-reactive protein.
In contrast, the control group displayed signs of liver stress and inflammation upon analysis. Our findings indicate that oregano, alongside other essential oils, could mitigate the negative effects of trichothecenes on liver health in calves, serving as a potential aid in improving overall animal wellbeing and health resilience.

In our exploration of the effects of oregano (Origanum vulgare) on liver health, we conducted a thorough study using rats to assess its potential as a treatment for hepatic encephalopathy (HE). This condition is often linked with chronic liver disease and can lead to a decline in brain function due to elevated ammonia levels.
We analyzed the chemical makeup of oregano's hexane extract, identifying 25 different compounds, with prominent elements like cholesten-3-one and gamma-tocopherol. To test its effectiveness, we divided the rats into seven groups: a control group, groups receiving different doses of oregano, and groups treated with thioacetamide (TAA), which induces HE.
Throughout the study, we measured various outcomes, including behavior changes, body weight, and blood markers. TAA caused anxiety and cognitive impairments in the rats, alongside significant weight changes and liver stress. Remarkably, treatment with oregano significantly improved these symptoms, showcasing its potential as a hepato- and neuroprotective agent.
We found that oregano’s protective effects were comparable to those of silymarin, a standard liver treatment. Both treatments helped mitigate the damaging effects of TAA on the liver and brain, suggesting that oregano could be an excellent alternative in supporting liver health and function.
