<human>: How long does it take garlic capsules to help lower blood pressure - I am already on two types of b.p. medication and while it is much better the bottom number is still around 90 - Id like to lower it more and was hoping taking garlic capsules would help...???
<bot>: Garlic capsule and cod fish oil are advocated for lowering of BP.  However, large trials have not been able to prove direct association.  Also, the individual papers achieved max 4-5 mm fall in Upper systolic and 2-3 mm fall in lower diastolic.  So if you want to take garlic capsule for over all health benefit, it's ok.  But please don't substitute it as one antihypertensive.  Also, as I said the max achieved should be borne in mind.  Regards Chat Doctor.
