• Gastrointestinal effect – inhibits H.pylori and thus development of gastric ulcers; alleviates the symptoms of dyspepsia
• Hepatoprotective activity
• Antispasmodic activity – shows to decrease smooth muscle contractions in trachea, ileum, colon and stomach: reduction of stomach and intestinal motility leads to decrease in number of stress – and serotonin induced ulcers; inhibits histamine and barium induced ileum contractions
• Anti-dysmenorrheal activity – reduces the severity and duration of pain during menstruation; reduces nausea and severity of menstrual bleeding
• Insuline-like activity – shows to increase glucose utilisation
• Anti-diabetic effect – exhibits insulins-like activity; inhibits various digestive enzymes which leads to decreased influx of glucose into systemic circulation and thus avoid overly significant insulin spikes; shows to reduce blood glucose levels and improve lipid profile (LDL, triglycerides and total cholesterol)
• Anti-hyperlipidemic activity – shows to inhibit HMG-CoA reductase and thus inhibits biosynthesis of cholesterol; inhibits pancreatic lipase and thus absorption of fats through intestine; shows to possess moderate cholesterol esterase and cholesterol micellization inhibition and bile acid binding; inhibits lipid peroxidation and thus protects from oxidative stress
• Anti-obesogenic effect – increases insulin sensitivity; reduces ghrelin secretion; lowers blood glucose and improves serum lipid levels; inhibits intestinal lipid absorption; inhibits lipolysis and lipogenesis thus can be used in supportive therapy for treatment and prevention of metabolic syndrome
• Cardioprotective effect – improves lipid profile and protects agains development of atherosclerosis (inhibits vascular smooth muscle cell proliferation through blockage of thromboxane A2 receptors mediated proliferation); has anti-hypertensive effect and causes vasorelaxation; shows to enhance cardiac force and contractility, have positive inotropic effect, improve heart performance and increase coronary flow; shows to improve cardiac hemodynamic in long-term aerobic training
• Antimicrobial activity – shows to have antibacterial (e.g. E.coli, Staphylococcus aureus, Staphylococcus epidermidis, Salmonella spp., Pseudomonas aeruginosa, H.pylori) and anti-fungal properties (e.g. C.albicans, Aspergillis spp., Cladosporium weneckii); shows anti-HIV-1 activity
• Antioxidant effect – inhibits lipid peroxidation and have free radical scavenging activity
• Anti-inflammatory effect – shows to inhibit COX-2 catalysed prostaglandin E2 biosynthesis; decreases TNF alpha, IL-6 production and other pro-inflammatory cytokines; decreases expression of mast cell-specific mediator and thus can be used for anti-allergic therapy
• Иммуномодулирующее действие
• Neuroprotective effect – shows to restore myelin level and protect myelin-specific genes in spinal cord; has anti-inflammatory and antioxidant properties; shows to inhibit formation of amyloid-beta plaques in Alzheimer’s disease, prevents its toxicity and improve cognitive behaviour; shows to protect dopaminergic neutrons, normalise striatal neurotransmitter and improve motor functions in Parkinson’s disease
• Anti-cancer effect – shows to induce apoptosis and also suppressed tumor cell growth and the associated biomarkers in lung squamous cell carcinoma, hepatocellular carcinoma, breast and ovarian cancer cell lines as well as leukaemia

It has an anti-inflammatory action
