Citrulline supplements

[Mondo Buddha]

Has anyone had any success with using a citrulline supplement to alleviate an attack?

Hi Mondo. No, I have never known of a CHer who benefited from taking it either. It is a vasodilator and generally, we don't want to open our blood vessels as it can put pressure on the Trigeminal Nerve that is involved in Clusters. 

On occasion, we may sit in a super hot shallow bath to open the blood vessels in our lower body to alleviate some of the pressure in our head. But that is very different from all over dilation.
