Mah (Melatonin) acts as a potent antioxidant and neurohormone that modulates neurotransmitter release and circadian rhythms, potentially reducing inflammatory processes and neurogenic inflammation associated with cluster headaches. By binding to melatonin receptors (MT1 and MT2) in the central nervous system, it helps regulate sleep patterns and may decrease the frequency and intensity of cluster headache episodes through its neuroprotective and chronobiotic properties.
