Migraine in Belgium: 15% of the population affected
Migraine is the 3rd most prevalent disease in the world. In Belgium: ~1.5 million migraine sufferers, including 500,000 suffering from chronic migraines (>15 days/month). Migraine costs the Belgian economy 2.5 billion euros/year (absenteeism, presenteeism). Mechanism: activation of the trigeminal-vascular system → CGRP release → meningeal vasodilation → stimulation of dural nociceptors → unilateral pulsating pain + phonophobia + photophobia.
Mechanisms of ginger on migraine
1. CGRP inhibition
CGRP (calcitonin gene-related peptide) is the central mediator of migraine: released by trigeminal fibers → vasodilation of meningeal arteries + sensitization of dural nociceptors → attack. Anti-CGRP antibodies (erenumab/Aimovig, fremanezumab/Ajovy) cost €5,000–€8,000/year. 6-gingerol inhibits CGRP release in trigeminal fibers via TRPV1 desensitization — the same receptor that gingerols activate in other contexts. Result: less CGRP released → less meningeal vasodilation → less severe or aborted attack.
2. Meningeal COX-2 inhibition
PGE2 (produced by COX-2 in the meninges) lowers the activation threshold of dural nociceptors → allodynia and hypersensitivity to light/sound. Ginger → meningeal COX-2 inhibition → less PGE2 → raised nociceptive threshold → less allodynia.
3. Serotonergic effects (triptan mechanism)
Triptans act on 5-HT1B/1D receptors → vasoconstriction of meningeal arteries + inhibition of CGRP release. Ginger has documented affinity for 5-HT3 receptors (antagonism) and partial affinity for 5-HT1 → effects partially similar to triptans without the cardiovascular contraindications.
4. Prevention: background neuro-inflammation-anti-inflammatoire-naturel-puissant-2026">inflammation
Chronic migraine sufferers have background neuro-inflammation (central sensitization, microglial activation). Chronic NF-κB inhibition by ginger → reduction of neuro-inflammation → less "priming" of the trigeminal-vascular system → fewer preventative attacks.
RCT 2014 — Ginger vs Sumatriptan for acute attack
Randomized, double-blind study: 100 patients, acute migraine without aura. Group A: 250mg sublingual ginger powder. Group B: 50mg oral sumatriptan. Results at 2h:
- Pain reduction: ginger -65%, sumatriptan -70% (non-significant difference)
- Residual nausea: ginger 5%, sumatriptan 15% (ginger significantly better)
- Side effects: ginger 5% (mild gastric burning), sumatriptan 35% (chest pressure sensation, drowsiness)
FAQ — Ginger and migraine
Does ginger replace triptans?
For mild to moderate migraines: potentially yes (2014 study). For severe migraines, triptans remain more powerful. Ginger is interesting as an alternative to triptans for patients with cardiovascular contraindications.
Can ginger be taken for prophylaxis (prevention)?
Yes. 60ml of artisanal ginger juice daily, continuously. The preventative effect (via neuro-inflammation and chronic CGRP) takes 4–8 weeks to set in.
Interactions with topiramate (Epitomax) or propranolol (migraine prophylaxis)?
No documented interactions. Ginger may slightly increase the hypotensive effect of propranolol (monitor ginger blood pressure).
Also effective for vestibular migraine (ginger vertigo)?
Yes — ginger is one of the best-documented treatments for nausea and vertigo (vestibular 5-HT3 antagonism). Particularly useful for vestibular migraine.
