Why this happens

Both amlodipine and garlic work to lower blood pressure (amlodipine by relaxing blood vessels and garlic through natural compounds like allicin). When used together, their effects can add up. Additionally, garlic has mild blood-thinning properties which can affect how your blood clots.
