I agree with Ausdoc. Until this methodology has been throughly investigated and long term studies carried out, no one really knows how potential side effects will present.
I'm a GP and some 40% of my patients have essential hypertension, and in my practice we do a pretty good job of managing to control their condition with a regime of well proven ACE's; Ca channel blockers, beta-blockers et al and of course it's a trade off between side effects and keeping BP under control.
