Are there remedies, like teas or vitamin pills that will keep blood pressure from getting too high?

I’m looking for an alternative from doctor precribed medication.

my mother has high blood pressure and it got real high last night at 170/105. my question is are there any natural remedies that may help lower her blood pressure so she can wing off medication besides exercising and healthy eating? i know that’s the reason why it’s high in the first place, but is there anything specific that may help?

Does One a Day Men’s Health Forumla reduce blood pressure when it is taken regularly? Also, is there a sort of dependency on this vitamen (drug)? For instance: It’s taken once a day for 3 weeks, will I HAVE to continue taking it daily, or can I stop anytime I want?

Will my blood pressure rise if I were to stop taking it?

[what are good methods of lower blood pressure?]

I am w/o insurance for a few months and my usual medicine is a FORTUNE w/o insurance. Does anyone have any good name brands or home remedies?

Thank you for your help.
