Studies on the Antiviral Effect of Preparations from Garlic

The antiviral effect of garlic and its organosulfur and lectin compounds is beyond any doubt. In vitro experiments demonstrate the virucidal effect on viruses without envelopes or with envelopes. The latter are the ones causing pandemics. The antiviral mechanism of action include various targets, e. g. receptor interaction, inhibition of enzymes that enable penetration into cells, inhibition of replication and excretion of virions. Seven exploratory studies indicate a potent antiviral effectiveness in humans. Confirmatory studies must now evaluate the effect size for every garlic preparation after dose-finding studies have established the optimum daily dosage for the prevention and treatment of viral infections.
