If garlic had been created in a test tube, it would most certainly be a very high-priced prescription drug. Taking garlic has an abundance of health benefits. In fact, it has been used medicinally for at least 3,000 years. Today, we are just now discovering what many ancient civilizations, including the Romans, Greeks and Egyptians already knew – garlic boosts strength and prevents disease. It’s even been said that garlic made Egyptian pyramid-builders stronger and Roman legions more courageous.

Taking garlic regularly can help prevent many chronic health conditions. Studies show garlic is a natural antibacterial and antifungal. It helps with lowering cholesterol naturally and simultaneously acts as a blood thinner. It boosts immunity due to its antioxidant properties and research has shown it prevents both cancer and cardiovascular disease. It can even treat gastritis. Perhaps one of the most promising actions of this natural “wonder drug” is its ability to lower blood pressure. But contrary to its pharmaceutical counterparts, garlic can accomplish all of these health benefits without the plethora of side effects!

Garlic contains allicin, one of the most beneficial high blood pressure remedies. A study conducted by researchers from the Russian Academy of Medical Sciences investigated the effects of time-released garlic powder tablets on men with mild to moderate high blood pressure. The research showed that taking a 600 mg time-released garlic tablet decreased blood pressure levels.[1]

How does garlic fight high blood pressure symptoms?

As the body increases production of an enzyme called angiotensin I-converting enzyme, or “ACE”, blood pressure increases. Pharmaceutical drugs called ACE inhibitors work by blocking the formation of this enzyme, but they have multiple side effects. (Read 3 Ace Inhibitor Side Effects to Be Aware Of,.)  Garlic contains gamma-glutamylcysteine, a natural ACE inhibitor.  This chemical, in combination with the high allicin content, give garlic its ability to dilate arteries, thereby lowering blood pressure.

How do I take garlic?

A fresh clove of garlic (4 grams) contains 1% allicin. You can dice up one fresh garlic clove daily and add it to your dishes, but it may leave you with rather unpleasant breath.  Garlic supplements are available in several forms such as pills, powders, oils, and extracts ranging anywhere from 100 mg up to 5,000 mg. Since some garlic supplements contain little or no allicin, be sure to check the label for adequate allicin levels. You can also buy pure allicin supplements. In this case, follow the manufacturer’s dosage instructions.  If you choose garlic extract, take 600 to 1200 mg divided in three doses per day.


Because garlic is a natural blood thinner (anticoagulant), taking it in combination with blood thinning medications can be risky. If you are taking a blood thinner or an ACE inhibitor blood pressure medication, be sure to consult an integrative physician before beginning garlic supplements.

    One day at 73 I had a routine health check and my GP got a reading of 188/79. She panicked and so did I and I still can’t believe that I walked out of that surgery with a BP script which I filled on the way home. I was scared, my grandmother died of a stroke at 66. But why was I so stupid and did not decide to monitor the BP for some time before taking the medication?? After 5 months I developed a serious case of urticaria that got out of control and I ended up in hospital. The specialist took me immediately off the medication and put me on cortisone which also had disastrous effects on my wellbeing. I developed what the doctor diagnosed polymyalgia rheumatica and said that there is no cure for this I had to take cortisone for the rest of my life. I still had frequent episodes of urticaria and visited a number go GPs and they all disbelieved that the urticaria was caused by the BP medication. I finally quit conventional medicine and visited a highly respected and clever Naturopath. He explained to me that the medications seriously undermined my gut health and consequently my immune system. Soon after starting my natural treatment I got well again, my blood pressure dropped dramatically . I have an excitable personality that influences my systolic BP and the naturopath suggested meditation which I am now doing daily with excellent results. I currently take Curcumin, Garlic (natural and supplements) Magnesium, fish oil, Echinacea, coleus, Vit D3 and Ubiquitol, (quite a handful on a daily basis), but I have never felt better and I am a very active 76!

    Fresh garlic is one of my favorite health foods. I work at least a couple of cloves of fresh pressed garlic into my diet pretty much every day.

    My favorite way of eating raw garlic is by making my own guacamole. I mash together some avocado, fresh-pressed garlic, black pepper, non-GMO miso (a salty probiotic that also contains vitamin K2), and a bit of turmeric and ginger (both either powdered or — when I’m feeling ambitious — as freshly grated whole root). Then I take a couple of Wasa rye crackers, smear them with plenty of butter from grass-fed cows (which contains D3 and more K2), add a slice of gouda cheese (another good source of K2), spread the guacamole on top of the cheese, and sometimes a slice of fresh tomato on top of all that. Adding a slice or two of bacon and a couple of free-range eggs fried in the bacon grease, plus a cup of green tea with fresh lemon juice and sweetened with stevia, and I have a super-super-food breakfast feast fit for a king.
