-Showed immunotherapeutic effects against Newcastle disease virus -Reduced virus shedding and enhanced immune responses against the effect of avian influenza in turkeys -Significant decrease in serum level concentration of malondialdehyde (MDA) and nitric oxide (NO) -Significantly improved hepatitis C virus(HCV) viral load in human subjects -Significantly reduced the systolic blood pressure, diastolic blood pressure, means arterial pressure, and heart rate in human subjects. -Human volunteers witnessed a decrease in clinical symptoms, including nasal itching, rhinorrhea, sneezing attacks, nasal congestion, turbinate hypertrophy, and mucosal pallor. -Significant enhancements were observed in forced expiratory volume in one second (FEV1), peak expiratory flow (PEF), serum interferon-γ, and asthma control test (ACT) score in human subjects. -Considerably reduced the risk of lung damage in rats -Antimalarial activity in Swiss albino mice -Protective effects against rheumatoid arthritis. Significantly reduced the serum levels of HNE, IL-1β, TNFα and bone turnover markers. -Combined effect with α-lipoic acid(α-LA), L-carnitine reduced elevated blood glucose level in diabetic rat model -Boiled extract of caused significant increases inpulmonary function tests (PFTs), showed potent antiasthmatic effect on asthmatic airwaysin human patients -Reductions in fasting blood sugar (FBS) and HbA1c,increased the β-cell functions. -Markedly decreased the function of inducible nitric oxide synthase (iNOS) and an increase in surfactant protein D in lung tissue -Increased the suppressor function of Mφ in spleen andantiviral showed activity against murine cytomegalovirus in mice -Boiled aqueous extracts improve all asthmatic symptoms, asthma symptom/week, chest wheeze in patients |
