Background and Objective: SARS COV-2 is a worldwide pandemic disease. There is currently no effective cure for this virus, but some types of herbs can be a good choice for reducing its symptoms. There are some reports that Thymus Vulgaris has a high antioxidant compounds effective in strengthening the immune system, as well as anti-virus effects to reduce the respiratory symptoms. Therefore, we speculated that Thymus Vulgaris could be useful for reducing some of the symptoms in patients suffering from COVID- 19.
 Materials and Methods: First, thyme essential oil was prepared and a questionnaire regarding the patients’ symptoms was designed. Then, 83 patients with COVID-19 were randomly selected and divided into control group and thyme receiving group (TRG). The questionnaire was completed and emphasized to consume 5 mL of the syrup or essential oil three times per day. Finally, one week after the first visit, the questionnaire was completed again to determine the effects of thyme on the mentioned symptoms. Finally, the test results were reviewed and reported.
 Results: The results one week after taking thyme showed that, the fever (p<0.027), dizziness (p<0.003), cough, dyspnea, muscular pain, headache, anorexia, weakness and lethargy, fatigue, and chest wall pain were significantly reduced (p<0.001). Also, BUN (p<0.004), neutrophil count (p<0.001), and calcium (p<0.034) decreased but, lymphocyte count was increased significantly (p<0.001).
 Conclusion: Thyme plant which has high antioxidant properties, strengthens the immune system, and induces the antiviral effect could reduce the symptoms of coronavirus; therefore, it is recommended for reducing the symptoms of COVID-19.

Background and Objective: Plantago psyllium has long been utilised as a medicinal agent worldwide. The current study aims to evaluate the in vivo antimicrobial effects of aqueous P. psyllium and a hydro-alcoholic extract of P. psyllium on Helicobacter pylori as well as the effects of these extracts on liver and kidney in a rat model.
Materials and Methods: A total number of 50 female Sprague Dawley rats were experimentally infected (Except for the negative control group). The rats were divided into five groups of 10. The groups were treated by Aqueous and Hydro-Alcoholic P. psyllium leaf extracts. Subsequently, H. pylori antigens which were present in the in rats’ stool were measured using a serological assay. To diagnose the pathogenicity of the kidney and liver, blood samples which had been taken before and after treatment, were tested for renal and hepatic enzymes by Analyzer Electrolyte and Sysmex KX-21N.
Results: Following the amoxicillin treatment, the levels of aqueous and hydro-alcoholic extracts of the treated rats were compared with those of the control group, and a significant difference was observed (P<0.05). Antigen decrease was observed in all of the groups treated with amoxicillin (P=0.0004), aqueous, and hydro-alcoholic extracts (P<0.05). Antigen decrease in the stool was observed in all groups, which indicates that treatment with the herbal extract could affect the infected rats.
Conclusion: P. psyllium hydro-alcoholic extract can be applied as a selective treatment for H. pylori infection. Hopefully, experiments suggested that the mentioned extracts could positively affect the process of disease recovery.

Background and Objective: Increment in cancer prevalence and subsequent need for chemotherapy leads to distinct kidney-related diseases such as acute kidney injury (AKI). Cisplatin is a common chemotherapeutic agent that has been used in many cancers; however, it can damage renal cells. Capparis spinosa is an important therapeutic plant in Persian medicine that encompasses high amounts of bioactive antioxidant components. The current study aimed to evaluate the nephroprotective effects of Capparis spinosa seed hydroalcoholic extract (CSSE) against cisplatin-induced nephrotoxicity in vivo through histopathological evaluation.
Materials and Methods: Forty Sprague Dawley rats weighing within the range of 230±20 gr were randomly divided into eight groups including sham, a single-dose cisplatin intraperitoneally (IP) injected group (7 mg/kg), toxic dose CSSE (200 mg/kg) group, and groups with cisplatin 7mg/kg IP and different doses of CSSE. Histopathological changes in the kidney tissues were quantified by the image-J program and analyzed by statistical methods.
Results: Cisplatin-induced glomerular and tubular injuries in the kidney tissue. A single-dose cisplatin decreased the glomerular area and Bowman's capsule area, increased Bowman's space, and induced tubular loss of brush borders, tubular dilatation, tubular cast formation and tubular necrosis. All of the changes were reversed by CSSE significantly.
Conclusion: Post-CSSE (50 and 100 mg/kg) treatment could protect against cisplatin-induced nephrotoxicity in vivo. More clinical studies are needed to confirm its protective effects on the prevention of kidney injury in chemotherapy receiving patients.

Background and Objective: Cisplatin as a chemotherapy drug causes liver damage by increasing inflammation. Hepatoprotective agents with antioxidant properties can be useful for preventing this complication. Capparis spinosa, as a natural antioxidant source, can help to eliminate these productions. The purpose of this study was to determine the effect of two different doses of hydroalcoholic extract of Capparis seed on cisplatin-induced liver damages in rats.
Materials and Methods: Forty male rats were divided into five groups (the control group, Cis (cisplatin) group, 200 C/S (Capparis spinosa), Cis + 50 C/S, and Cis + 100 C/S). Biochemical and histopathological evaluations were made. At the end of the study, all animals were euthanized with a CO2 gradient. Statistical analyses were performed through Graph Pad Prism Statistics software 9.1.2. The level of significance was set at p < 0.05.
Results: Liver function tests, antioxidant and inflammatory markers and histopathological changes were evaluated. Significant changes in the pathology results were noticeable. Central vein, portal vein and bile duct diameter, thickness of the hepatic artery wall, and hepatic sinusoids were significantly increased in the Cis and 200 C/S-fed groups, compared to the controls, and also changes in favor of improvement were evident in the treatment groups, especially in the Cis + 100 C/S group compared to the Cis and 200 C/S groups.
Conclusion: Based on pathology results, treatment with C. spinosa seed extract may be helpful in preventing cisplatin hepatotoxicity.
