Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Allicin, a sulfur-containing compound derived from garlic (Allium sativum), has a long history of use in traditional medicine for treating various infectious diseases, including respiratory illnesses like influenza. The traditional rationale for its use is based on garlic’s general antimicrobial properties and its status as an herbal remedy for colds and flu-like symptoms in many cultures.

Some laboratory studies have demonstrated that allicin exhibits antiviral and immune-modulatory effects in vitro, including actions against certain strains of influenza virus. However, high-quality clinical trials in humans specifically examining allicin’s effectiveness against influenza are scarce. A few small human studies and randomized controlled trials have suggested that garlic supplementation may reduce the incidence or duration of common colds, but these do not directly address influenza infection.

Overall, while there is a plausible biochemical basis and extensive traditional use supporting allicin’s use for influenza, robust clinical evidence is lacking. Its use for influenza is therefore best described as supported by tradition, with some preliminary scientific rationale but limited direct validation.
