Research suggests that black garlic possesses meaningful anti-inflammatory properties, primarily demonstrated through its ability to suppress key inflammatory signaling molecules such as NF-κB, TNF-α, IL-6, and prostaglandin E2, with supporting evidence coming from a collection of cell-based studies, animal experiments, and multiple narrative reviews published between 2014 and 2026. Studies indicate these effects are linked to bioactive compounds — including S-allyl-L-cysteine, polyphenols such as gallic acid and catechin, and Maillard reaction products — that are generated or concentrated during the controlled heat-and-aging process used to produce black garlic. However, the evidence is not without nuance: several reviews note that raw garlic may actually outperform black garlic specifically in anti-inflammatory activity, with one study suggesting that sugars accumulated during aging may partially blunt these effects, even as black garlic offers advantages in antioxidant activity, palatability, and reduced toxicity. The overall body of evidence remains largely preclinical, with no randomized controlled trials or large-scale human studies currently represented in the literature, and reviewers consistently call for more rigorous, standardized research before strong conclusions about black garlic's anti-inflammatory benefits in humans can be drawn.
