Can garlic cause low blood pressure?

Garlic, the ancient herb known for its unique flavor and pungent aroma, has been used in traditional medicine practices for centuries. It is believed to have numerous health benefits, including lowering blood pressure. But can garlic cause low blood pressure? Despite its many medicinal properties, it’s essential to know whether there are any risks associated with consuming garlic.

The Benefits of Garlic

Before we delve into the question of whether garlic can cause low blood pressure or not, let’s take a moment to appreciate some of the remarkable benefits attributed to this herb:

  • Garlic contains allicin, which has antibacterial and antifungal properties.
  • It may reduce the risk of heart disease by improving cholesterol levels.
  • Some studies suggest that regular consumption of garlic may help lower high blood pressure (hypertension).
  • Garlicky meals add tons of delicious flavor!

While these beneficial effects do sound promising enough to make us want to stock up on garlic at home; however, we still need conclusive answers about if anything less desirable backs it similarly.

Let’s Talk About Blood Pressure

Blood pressure is the force exerted against arterial walls as your heart pumps out oxygen-rich blood throughout your body. A healthy range for an adult is between 90/60 mm Hg and 120/80 mm Hg. When your BP falls slightly below this range due to various causes – One potential cause being excessive amounts of cloves being consumed (oh no!) − it triggers hypotension: LOW BLOOD PRESSURE.

Hypotension symptoms include dizziness or lightheadedness when standing up after sitting/sleeping hours together punctuated with nausea times crawling underneath one’s skull ( Yikes!). Did someone say ‘get off my back I am feeling dizzy?’

How Does Garlic Help Lower High Blood Pressure?

Studies have suggested that certain compounds in raw garlic relax blood vessels, allowing more blood to flow through; and as a result lowers high BP. These findings have given us enough reason to believe in garlic’s potential health benefits.

However, these studies are far from definitive – we still don’t understand if it would adversely lower blood pressure too much easily in people who already have hypotension (Good luck).

Can Garlic Cause Low Blood Pressure?

If garlic is consumed excessively or not cooked adequately, there’s the likelihood that people may experience some undesired effects such as low blood pressure! Oh dear… Where am I? How did I get here? Garlic-induced hypotension has been found primarily when:

  • Individuals consume raw cloves continuously without moderation.
  • Taking supplements with concentrated amounts of allicin (the contributing compound discussed earlier).
  • When trying out non-traditional ways of consuming garlic like: rubbing cut garlic on gums for supposed anti-flu benefit(not worth it);)

So yes, excessive consumption CAN indeed cause some people low BP symptoms!

On the brighter side—you can still enjoy garlicky foods without worrying about fainting after meals—be smart about meal prep and portion size!

Who Is at Risk for Hypotension Caused by Garlic Overdose?

Not every garlicky dish lover will go weak at their knees after eating — It usually only affects some individuals with existing medical conditions such as hypertension diabetics , pregnant/breastfeeding individuals should consult their doctor before consuming large amounts of raw/crushed/pickled/roasted/sautéed…( you get my drift..just stay off nomming any form of excessive intakes until confirmations been received).

Also PRO TIP –While using medication meant to LOWER your hypertensive levels (like beta blockers), avoid heavily indulging in dishes made with overbearing levels of onions or our star veg because they could amp up the medicine strength & surprise you with hypotension.

How Much Garlic is Too Much?

Garlic cloves are jam-packed with nutrients and incredible flavors. And when used in meals or as a supplement (when appropriately prepared), it’s unlikely to cause harm.

However, when taken under certain circumstances discussed above, everything has a tipping point; keep within the 15mg/kg of body weight if you don’t want your BP levels falling below healthy range (Don’t add swimming to any post-garlicky feast plans).


Nature continues to remind us that although we believe ourselves invincible – all good things have limits especially useful herbs like garlic.Granted garlic is a culinary delight but let us not overdo our enthusiasm for its benefits which could potentially drown us into the symptoms associated with Low Blood Pressure.

Anything consumed moderately ensures no potential damage but consuming large amounts without deliberation could result in prolonged discomfort – even consequences of significant health issues including troublesome digestion—a series of diarrhea episodes/renal/kidney challenges(countries worldwide use it as medicine).

So next time you reach out for the jar of minced garlic, remember using simple moderation will allow both flavor & health aspects flourish well!
