The influence of kava on blood vessels?

[aviavieu]

Do the blood vessels narrow or widen after drinking kava?
I subjectively think that they contract, at least you can feel it at the beginning.

This article suggests, 'kavain impairs vascular smooth muscle contraction, likely through inhibition of Ca(++) channels.'
My take is kava is neither a strong vascular consttictor or dilator, it leans more towards dilation [vessel widening] which, in my experience keeps us warm and promotes healthy blood & water circulation.

By feeling you mentioned, ocular sensitivity increases, maybe that is eye vein contraction. Bula.

I would have guessed the other direction (constriction) and hence why you get the kava "chills" sometimes during a session.

Sounds good Zaphod.

Chugging water at 300-500ml gives me the chills also.
