Garlic is an herb that I always have on hand, usually in several different forms. From powder, salt, and minced for cooking to fresh for both cooking and wellness — this herb has a plethora of uses besides being tasty!

Garlic: Revered or Feared?

Garlic is one of the oldest cultivated herbs dating back to more than 5,000 years ago, but its place in society has wavered. Some cultures saw garlic as an herb fit for the gods, while others found it repulsive and fit for only animal feed. Its use in society stretched the gamut of these beliefs.

In fact, the ancient Egyptians worshipped garlic as a god and also used it as currency! Because of this, Egyptians swore on cloves of garlic much in the way some swear on the Bible. Interestingly, only the lower-class actually ate garlic because the rich believed it was too “coarse and common” for their delicate palate. In Greece, India, and England, garlic was considered too pungent for upper-class people to eat.

Despite all the controversy, many cultures believed garlic was protective. In ancient Korea it was thought that tigers hated the smell of garlic, so people would eat pickled garlic before traversing the mountains. In ancient Greece, midwives hung cloves of garlic on the window to ward off evil spirits during childbirth. They also used garlic internally as a medicinal herb despite (or because of) its strong odor and taste.

But because of this strong taste, herbalists have been torn throughout history as to whether garlic was indeed helpful or an herb best avoided. There is one legend that goes, “When Satan stepped out from the Garden of Eden after the fall of man, Garlick sprang up from the spot where he placed his left foot and onion from that where his right foot touched.”

Garlic has been linked to romance and thought of as an aphrodisiac. It has also been used as an antiseptic during wartime and, famously, in the four thieves remedy that protected plunderers during the plague. Today we enjoy garlic for its amazing flavor and many medicinal qualities as studies have been piling up to support garlic’s use as an herbal remedy for many ailments.

Science-Backed Reasons to Eat Garlic

In modern times, garlic still enjoys being loved by many (and hated by some). I’m married to an Italian so you can guess the feeling in our house!

But there are reasons to eat garlic that have nothing to do with flavor and everything to do with health…

Healthy Heart and Metabolic Function

Some evidence suggests that garlic may help promote heart health and fight heart disease. Garlic may slow down atherosclerosis (hardening of the arteries) and lower blood pressure slightly, between 7% and 8%. (Most of the studies on high blood pressure have used a specific formulation called Kwai.)

One study that lasted 4 years found that people who took 900 mg daily of standardized powder slowed the development of atherosclerosis. It also seems to be an anticoagulant, meaning it acts as a blood-thinner, which may help the fight against heart attacks and strokes.

Additionally, a 2010 placebo-controlled trial included 50 patients with hypertension. The trial concluded that aged garlic was as good as hypertension medications in lowering systolic blood pressure.

Finally, research shows that garlic can also help reduce blood sugar levels as well as cholesterol levels and triglycerides.

Healthy Hair

According to a 2009 study, garlic can help reduce hair loss when used topically. It also has negligible side effects, making it a safe choice. Infuse garlic cloves in olive oil to make a garlic oil and rub into the scalp as needed.

Protects Against Group B Strep

A local midwife suggests consuming a raw garlic clove or capsule of garlic daily, along with 2,000 mg of vitamin C to help balance gut bacteria and avoid GBS. Anecdotally, this remedy worked for me in my past two pregnancies after testing positive during one pregnancy. But one in vitro study that looked at allicin extract’s effect on GBS in a petri dish found that garlic was able to kill the bacteria in three hours. More research is needed to know if this treatment works, but many midwives and moms swear by it.

Colds and Flu

According to a 2001 study, ingesting garlic can prevent the common cold or flu. But the evidence on garlic’s ability to shorten the duration of colds and flu seems to come from elderly friends and grandparents who swear by its effectiveness. But garlic is safe (and delicious!), so it’s worth a try. We consume fresh cloves during illness as needed.


Garlic may help treat fungal infections like athlete’s foot, one study published in Annals of Applied Biology discovered. But garlic can also be irritating to the skin, so be cautious and listen to your body when using undilute garlic juice or fresh garlic.

Repel Mosquitos

There’s no evidence that eating garlic or rubbing it on the skin repels mosquitos. But that doesn’t stop people from doing it anyway! Many swear that eating a lot of garlic in a camping meal helps repel biting mosquitoes. Garlic is a healthy food, so there’s no harm in trying it (just keep some natural bug spray close by too).


Garlic is anti-inflammatory and fights oxidative stress, making it a potential cancer fighter. A review article published in Cancer Prevention Research explains that garlic and other vegetables in the allium family affect many biological processes that modify cancer risk. Garlic can slow cancer cell growth and speed up cancer cell death. The studies looked at garlic’s effect on cancers including:

  • stomach
  • prostate
  • colorectal
  • esophageal
  • breast
  • larynx
  • ovary

However, the review points out that it is unknown how much garlic consumption causes a reduction in cancer risk. More research is needed to find this as well as to explore the connection between overall diet and lifestyle, garlic consumption, and cancer risk. The main takeaway is that there are anti-cancer properties in garlic, giving us one more reason to include it in a healthy diet!

Ear Infections

Ear infections can be bacterial or viral. Antibiotics obviously won’t help the viral cases, but garlic will. Garlic oil is a great remedy for ear infections. It is naturally antimicrobial, antiviral, and antibacterial. I make this recipe and keep it on hand when my kids need it.

How to Take Garlic

According to the University of Maryland Medical center, the following doses are considered generally safe doses but check with a doctor or healthcare professional before using any herb as a remedy:

  • Whole garlic clove: 2 – 4 grams per day of fresh, minced cloves (each clove is approximately 1 gram) (I try to consume 3-4 cloves daily)
  • Aged garlic extract: 600 – 1,200 mg, daily in divided doses
  • Freeze-dried capsules: 200 mg, 2 tablets 3 times daily, standardized to 1.3% alliin or 0.6% allicin. Products may also be found standardized to contain 10 – 12 mg/Gm allicin and 4,000 mcg of total allicin potential (TAP).
  • Fluid extract (1:1 w/v): 4 mL, daily
  • Tincture (1:5 w/v): 20 mL, daily
  • Oil: 0.03 – 0.12 mL, 3 times daily

Can Garlic Be Harmful?

Garlic is listed as Generally Recognized as Safe (GRAS) by the U.S. Food and Drug Administration. But always check with your doctor or herbalist as some herbs can interact with other herbs, supplements, or medications.

Side effects from garlic include:

  • upset stomach
  • bloating
  • bad breath
  • body odor
  • stinging sensation or lesions from handling garlic

Other, rarer side effects from garlic supplements include:

  • headache
  • fatigue
  • loss of appetite
  • muscle aches
  • dizziness/vertigo
  • allergies including skin rash and asthma

Garlic is considered safe for most people (including pregnant and breastfeeding women) in amounts found in food. It’s unclear if supplement doses of garlic are safe during pregnancy or breastfeeding.

Garlic may not be safe if you have the following medical issues:

  • Bleeding disorder or upcoming surgery – Garlic (especially fresh garlic) may increase the risk of bleeding.
  • Diabetes – Garlic can lower blood sugar so it may lower blood sugar too much in some people.
  • Stomach or digestion problems – Garlic may irritate the gastrointestinal tract.
  • Low blood pressure – Because garlic can lower blood pressure it may be unsafe for those with already low blood pressure.

Always check with your doctor to determine if garlic is right for you.

How I Use Garlic

Because of the benefit, I use garlic daily in some form:

  • I keep garlic powder, garlic salt, and minced garlic in the kitchen for easy use in cooking.
  • I finely mince 2-4 cloves a day or more and consume by taking a small spoonful at a time and washing down with water.
  • Fresh garlic cloves go into my salad dressings and fresh dishes.
  • I occasionally take garlic capsules for an extra boost.

Other ways to use garlic:

  • Simmer in olive oil to make garlic oil for earaches (put a few drops of cooled oil in the ear).
  • Treat thinning hair by applying garlic oil to the scalp.
  • Eat fermented garlic honey to boost the immune system during illness.
  • Garlic in the diet can be a natural remedy for group B strep during pregnancy (midwives advise eating a clove a day).
  • A footbath containing fresh cloves of garlic can help with athlete’s foot.
  • Reduce mosquitos in in your yard by using garlic-infused water on and around mosquito breeding areas.

Note: Garlic can be very strong, so try garlic oil or infused water before using straight garlic cloves on the skin.

    We have always used garlic for immune support and love it. But I recently read that most store-bought garlic is irradiated from China. Will it still be beneficial?

    This is such interesting information! When my baby is having ear infection I have been chopping garlic into small peaces, putting it to a sock and sock beside his ears. This has really helped to prevent and cure ear infections. Apparently it is the smell of fresh garlic which is killing bacteria. You don’t need to eat it or even put it on a skin. Now my friends are testing the idea as well. Now my son is 2 and he has never used antibiotics 🙂

    I got this idea from you and to make it manageable I spread coconut oil on spoon, mince up a clove of garlic, put a sprinkle of turmeric and/or cayenne pepper, then put a small amount of honey on top. I put that in my mouth and swallow it with a few gulps of water. It slides down effortlessly with minimal garlic taste and it works very well! This method also drastically reduces garlic breath for me lol I want to say thank you so much for all of your hard work. My boyfriend and I have incorporated many of your health practices throughout the past two years since finding this site. I know you’re geared towards mothers but you’ve planted such a beautiful/powerful seed in two 23 year old college students from orlando! You have literally changed our lives through your blog! I hope you’re having a wonderful week. God bless 🙂

    So it’ll be okay for me to consume raw garlic on the daily while pregnant? I had group b strep with my son which led to an infection which led to a c-section. I’m hoping and praying for a VBAC this time around and don’t want to be worried about passing group b strep to my second baby. I wish I would’ve found this article before having my son but so thankful to come across it now!!

    Garlic is the best thing for bee stings (wasps, anything that stings) I learned this long ago when I was stung by a bee at my uncle’s house. My aunt pulled out the stinger, my uncle cut a garlic clove in half and rubbed it on the bee sting. Ten minutes later it was if nothing had ever happened. I, many years later did the same thing when my niece was stung by a wasp, with the same result. 5 min later it was completely gone. No pain no itching no redness nothing.

    My daughter and I are both sick right now- horrible sore throats. Just wondering if you have to actually chew the garlic. I usually mince it and mix it with honey, the just swallow without chewing. As for my daughter, she is 2 and there is no way she will take the garlic. Any suggestions as to how to get her to ingest it?

      I realized that the its been almost a year since you posted this, but I get my two year old eat raw garlic by mincing up a clove, letting it sit for 5 to 10 minutes, and then mixing it with some peanut butter and honey. She loves it! You could even spread it on toast or a rice cake!

    2. Valerie Avatar

      When I can’t handle the taste, I smash up a clove in a ziploc baggie, then scoop it out and use a toothpick to insert it into empty capsules. Swallow immediately or that capsule will get eaten alive by the garlic!

    Hi Katy,
    Wonderful post in a tremendous blog! Thank you so much for all your healthy posts.
    I would like to share Something I learned awhile ago about garlic and onions. In order to gain full health benefits from either it is necessary cut them up, the finer the better, and let them sit for 5-10 minutes for the allicin to form from its base components.
    I hope you don’t mind if I post a link to another blog post that explains it as well as I have ever seen. Here it is:
    Please do keep up the good work you are doing!

    I have been eating toast with melted butter and a whole clove crushed spread on top. it is DELICIOUS! and I can feel the benefits of it. Less stress, more energy, and it is currently taking away my sinus infection because I don’t want to take antibiotics 😀

    Do you know how much garlic is considered safe during pregnancy? I would like to take raw garlic to help build up my immune system and also hopefully keep the group B strep at bay!

    For those who avoid sweets, peanut butter (instead of honey) also works for garlic nausea. I normally wouldn’t stick with something that made me queasy but, it works too well to quit.

    I love garlic. I mostly only use it in cooking, and I’m never sure just how much good it’s still doing – I know my herbalist once told me to very lightly saute it to release some of the goodness than goes to waste if you have it raw. But what if you have it in slow cooked stews, roasted, or sauted for longer, is it still beneficial?

    When I do feel myself coming down with something though, I tend to slice raw cloves of garlic and take it like a tablet, with water. Why minced, is it better digested that way?

      I’ve read that it is better digested when minced… It is still beneficial when cooked, but not as much as raw/lightly cooked…

    Also, we used to feed our dogs garlic powder during the warmer months to keep pests (ticks and such) to a minimum.

    Love Garlic! I’ve taken it to cure yeast infections caused by antibiotics. -works beautifully! I chop up a clove or two at a time and either take them with a spoonful of honey or put in a capsule (If my stomach is upset, I take it in capsule form, but take a couple teaspoons of honey to help with any nausea). Thanks for the info! Love your site!!!
