The evidence in words
The verdict
For hypertension, Garlic earns evidence grade B (unclear effect, mixed consistency) — there is real evidence here. Modest additive lowering
How it might work
Garlic's organosulfur compounds promote vasodilation (partly via hydrogen sulfide and nitric oxide) and modestly influence lipids and platelet function.
How to use it
Aged garlic extract or standardized allicin products dosed to deliver several mg of allicin potential daily; benefits accrue over weeks.
Safety & cautions
Odor and GI upset; antiplatelet action adds bleeding risk with anticoagulants and around surgery.
Bottom line
A rare kitchen supplement with real cardiovascular data: modest blood-pressure and lipid benefits. Mind the bleeding interaction if you're on blood thinners.
How it is used
As the entry records it, from the studies it summarises. Not a recommendation for you — doses that suit a trial population may not suit you.
- Standard
- Aged garlic extract / standardized allicin daily.
