David mentioned in one of the early classes that this is his favorite/most successful formula for vertigo -regardless of the cause, if I remember it correctly. I would like to try it on my mother-in-law who gets periodic dizziness for days. She has cerebellar ataxia which is obliviously one of the underlying causes but most of the time she does not experience dizziness so something must trigger it. Would there be any contraindications to this formula? E.g. in the description some manufacturers mention it lowering blood pressure - would it potentially cause hypotension in people with hypotensive propensity?
Any manufacturers you would recommend?
Thanks!
