Experts emphasize that results depend on quality, dosage and individual health status, and that Manuka honey is not a substitute for conventional medical treatment. Studies have suggested that Manuka honey may help reduce plaque accumulation and clinical signs of gingivitis. Evidence here is more limited than for wound care but remains consistent with broader honey research on cough and throat symptoms. Manuka honey contains phenolic compounds, flavonoids and other molecules that can neutralize free radicals and support cellular defenses against oxidative stress. While enthusiasm for Manuka honey is high, researchers caution that many studies remain small or preclinical.
