Pharmacological Effects • CNS stimulant: stimulates CNS; increases mental alertness, improves work efficiency, and quickens reflexes
• Hepatoprotective: associated with marked hepatoprotective effect against various types of drugs and/or chemical-induced toxicity; in one study, preparation of herb significantly lowered liver enzymes in mice with elevated SGPT levels caused by intraperitoneal injection of 0.1% carbon tetrachloride; in a follow-up study with rats, mice and rabbits, administration of schisandrol (dosages equivalent to 2.5 and 10.0 g/kg of dried herb) demonstrated marked preventative and treatment effects for carbon tetrachloride- induced liver damage; mechanisms of hepatoprotective function attributed to alteration of liver cell-membrane permeability to prevent entry of toxic substances, and increased blood flow to liver and increased regeneration of liver cells
• Gastrointestinal: deoxyschizandrin inhibits secretion of gastric acid in rats, and has shown beneficial effects in treatment of gastric ulcers; effective dose of deoxyschizandrin is 50 to 100 mg/kg
• Cardiovascular: appears to have regulating effect on cardiovascular system; while it may decrease blood pressure in normal subjects, it may increase blood pressure in those with weakened constitutions; laboratory studies indicate herb has vasodilating and cardiotonic effects
• Respiratory: water and alcohol extracts stimulate lungs to increase rate and depth of respiration; also shown to reverse respiratory depression associated with morphine
• Reproductive: administration of powder at 1 g/kg for 30 days in mice associated with stimulating effect on reproductive organs; the study reported an increase in weight of testicles in males and increase in ovulation in females
• Immunostimulant: associated with stimulation of non-specific immunity
• Antibiotic: alcohol extract has inhibitory effect in vitro against S. aureus, Bacillus anthracis, Salmonella typhi, Bacillus dysenteriae, Diplococcus pneumoniae, Vibrio cholerae, and Pseudomonas aeruginosa
Herb-Drug Interactions • Cycloheximide: herb has been found to significantly counteract cycloheximide-induced amnesia in rats; beneficial effect of the herb is amplified by treatment with serotonergic receptor antagonists, but reduced by serotonergic receptor agonists as well as GABA(A)and cholinergic receptor antagonists
