Platelet hyperaggregation occurs in the pathogenesis of migraine caused by one of the stimulatory factors 5-HT. Platelet aggregation is increased and 5-HT levels are elevated in the blood and brain in the early stages of migraine. Alkaloid β-carbolin alkaloids can increase monoamines in brain regions through inhibition of monoamine oxidase (MAO) and inhibition of 5-HT reuptake. Alkaloids in the ethanolic extract of SCE function as analgesics and anti-inflammatory which can reduce pain and improve blood circulation. &lt;em&gt;Sargassum cristaefolium&lt;/em&gt; extract (SCE) was measured for its bioactive substance content. The extract was administered to an animal model of intraperitoneal nitroglycerin-induced migraine and examined for platelet levels, platelet aggregation and 5-HT. The results of statistical tests showed an increase in platelets (p&amp;lt;0.05), an increase in platelet aggregation (p&amp;lt;0.05) and a decrease in 5-HT (p&amp;lt;0.05). The relationship between alkaloids and platelets; platelets and platelet aggregation; platelet aggregation and 5-HT and 5-HT levels and migraine incidence (p&amp;lt;0.05). The alkaloids found in SCE can lower platelet count, decrease platelet aggregation and increase 5-HT levels in migraines.&lt;/p&gt;
