Treatment for Cluster Headache
Garlic contains allicin and other sulfur compounds that exhibit vasodilatory and anti-inflammatory properties, potentially modulating cerebral blood flow and reducing neurogenic inflammation associated with cluster headaches. These compounds may help mitigate vascular constriction and decrease pain signaling through prostaglandin inhibition and nitric oxide modulation, though more research is needed to definitively establish its clinical efficacy for this specific condition.
