Proven health benefits of garlic and how to use it

Garlic (Allium sativa) is a plant with long, flat grass-like leaves and a papery hood around the flowers.

Fresh garlic contains active components like an amino acid called alliin and an enzyme called allinase which are very good for our healthcare.

When a clove of garlic is chewed, chopped, bruised, or cut, these compounds mix to form allicin, which is responsible for garlic’s strong smell.

Garlic also contains a wide range of trace minerals. These include copper, iron, zinc, magnesium, germanium, and selenium. 

For our good healthcare, garlic can be used for the following remedies:

Garlic' health benefits for Heart disease

How Heart disease occurs

Heart disease is mostly caused by the buildup of plaque on the walls of the blood vessels.

This plaque is mostly made up of cholesterol and other fatty substances found in the blood. anytime large amounts of plaque get stuck on artery walls, they block the flow of blood and cause blood clots to form. Parts of the artery wall may even be destroyed completely.

Studies show that people who eat garlic regularly have improved serum cholesterol levels. Some people with high cholesterol have been able to get within normal levels by eating 1–2 cloves per day. 

In addition, low-density lipoprotein (LDL) and triglyceride levels are decreased and high-density lipoprotein (HDL) levels are increased. 

This effect corelates with an overall reduced cholesterol level. These benefits are significant in preventing heart disease as well as strokes.

Manufactured garlic supplements appear to be equally as beneficial as eating fresh cloves. It takes at least one month of using garlic for laboratory results to be seen.

Garlic' health benefits for Hypertension

Hypertension, or high blood pressure, is also a significant cause of heart problems. It is one of the leading causes of disability and death due to stroke, heart attack, heart failure, and kidney failure.

Garlic can help reduce blood pressure through the actions of its sulfur compounds and its ability to reduce the fatty substances, such as cholesterol, found in the bloodstream. Use of garlic also can help normalize low blood pressure.

Garlic for improvement of Platelet aggregation

Platelets clot the blood in order to repair breaks in the blood vessel walls. When there is an injury, platelets are attracted to the damaged area and become attached to the wall and to other platelets. Platelet aggregation, as this process is called, plugs up the break and prevents further blood loss while the injury is being repaired. This is a good and necessary part of healing an injury.

If there are serious problems with the heart and blood vessels and there is too much injury and clotting, the vessels may become clogged with platelets, which can lead to strokes and heart disease. The sulfur compounds in garlic—particularly ajoene—give the platelets a slippery quality. 

They are less able to clump together, thus slowing down platelet aggregation. Garlic can be used effectively in the same way as a daily dose of aspirin to reduce or prevent platelet aggregation over an extended time.

Garlic' health benefits for Cancer

Studies have found that garlic blocks the formation of powerful carcinogens, called nitrosamines, which may be formed during the digestion of food.

This may be why in populations in which people consume a large amount of garlic, there is a decreased incidence of all types of cancer. The antioxidants found in garlic may also contribute to this effect by protecting against the cell damage by cancer-causing free radicals. Studies show that use of garlic may also inhibit the growth of a variety of tumors. However, cancer-related studies are not conclusive and relate to consumption of raw or cooked garlic, not garlic supplements.

Garlic as treatment for Infectious conditions

Eating garlic is good for helping the body’s immune system resist infections. While garlic is not as strong as modern antibiotics, it is believed to kill some strains of bacteria that have become resistant to antibiotics. Studies have shown garlic treats yeast infections, and it can kill many of the viruses responsible for colds and flu. 

While daily consumption of garlic was once highly recommended for HIV-positive individuals, the National Institutes of Health (NIH) reported in 2002 that garlic supplements greatly reduced levels of saquinavir, an HIV protease inhibitor, in patients’ blood. 

The NIH began cautioning patients who used garlic to control cholesterol levels who also used saquinavir or combination therapies, since garlic might interfere with their effectiveness.

Modern doctors, in reconsidering the causes of many diseases, have discovered that bacteria and viruses may be the cause of sicknesses that were formerly not thought to be caused by infections. Included are gastric ulcers, colitis, and Kaposi’s sarcoma. Garlic may be useful in treating or preventing these due to its antimicrobial properties.

Garlic' health benefits for Diabetes

Garlic has the ability to lower and help keep blood sugar stable by helping to increase the amount of insulin available in the bloodstream. This action, together with garlic’s ability to lower cholesterol and blood pressure, make it an excellent daily supplement for people with diabetes. 

A 2009 report showed that long-term use of garlic helped improve the blood vessel systems of diabetic rats.

Other health benefits of garlic 

Garlic is effective in the treatment of numerous other conditions. The following list provides some examples:

1.  The consumption of 1–3 cloves per day is useful for immune support and as a preventive against diseases and infection.
2.  Warmed garlic oil in the ear canal can be used to treat ear infections.
3.  Garlic can be used to treat respiratory complaints such as asthma and chronic bronchitis.
4.  Garlic helps increase the body’s ability to handle the digestion of meat and fats.
5.  Garlic can be used to help kill and expel intestinal worms in both animals and humans.
6.  When added to a pet’s food, garlic helps repel fleas.
7.  Garlic is helpful in getting rid of athlete’s foot.
8.  Garlic relieves gas and other stomach complaints.
9.  The sulfur compounds found in garlic can bind to heavy metals and other toxins and help remove them from the body.
10.  Garlic can be used externally for cuts, wounds, and skin eruptions.

 The taste of garlic in mother’s milk stimulates improved nursing. Infants eat more and nurse longer. They appear to relish the taste of slightly garlicky milk. The components of garlic that reach the infant through the mother’s milk also may be helpful in relieving colic and infections.

How to use garlic for good healthcare 

The internal usage of garlic

Garlic can be eaten raw or cooked, taken as tablets or capsules, and used as a tincture or syrup.

The suggested dosage for fresh whole garlic is one to three cloves per day. The cloves can be chewed and held in the mouth or swallowed. 

Consuming raw garlic can actually be a pleasure if the herb is crushed or grated and mixed with food or a tablespoon of honey. 

The dosage for tinctures is 2–4 ml or 15–40 drops taken twice daily. One tablespoon of the syrup should be taken three times a day, or as needed to relieve coughing. 

Garlic oil should be slightly warmed, and 1–3 drops should be put in the affected ear 1–3 times per day.

Tablets and capsules are often more convenient to use than raw garlic, and they are more likely to be tolerated by garlic-sensitive individuals. Garlic pills also minimize the garlic taste and odor. Manufacturers vary on which components of the herb are emphasized.

In general, the following dosages are appropriate, but product labels also should be consulted:

•  400–500 mg of allicin, twice daily
•  a dose equaling approximately 4,000 mcg of allicin
•  potential, once or twice daily
•  400–1,200 mg of dried garlic powder
•  1,000–7,200 mg of aged garlic
•  a dose equivalent to 0.03–0.12 ml of garlic oil, three times per day

Manufactured garlic pills come in a variety of forms, and a great deal of controversy continued in the early 2000s about what type is best. Studying the manufacturers’ literature and other information is important to make a good decision about which preparation to use.

The types of garlic preparations include:

•  Garlic oil capsules
•  Encapsulated powdered garlic
•  Odorless garlic pills
•  Allicin-stabilized pills
•  Aged garlic extract

External usage of garlic for good healthcare 

The raw cloves can be directly applied externally.

A poultice can be made using grated or crushed fresh garlic. The herb material should be placed directly on the site of injury or eruption, either as is or mixed with enough honey to make a paste. The poultice can be held in place with a cloth or bandage.

A compress of garlic is less messy than a poultice and may be less irritating to the site of the injury. It is made by wrapping grated or crushed fresh garlic in a single piece of cheesecloth. As with the poultice, the compress is placed directly on the affected area.

Garlic oil can be made by putting a whole bulb of grated or finely chopped garlic into a pint jar of olive oil, and letting it sit undisturbed in a warm place, away from direct sunlight, for at least two weeks. Then it can be strained and refrigerated. The garlic oil will stay fresh in the refrigerator for up to two years.

A garlic suppository can be used to treat vaginal yeast or mild bacterial infections. A clove of fresh garlic should be peeled and slightly crushed or bruised.

If crushed garlic irritates the vaginal tissue, an alternative that might lessen the desired antimicrobial effect is to use the whole, uncrushed garlic clove. 

The clove should be wrapped in a single layer of cheesecloth and inserted into the vaginal canal overnight for 5–10 days. 

Dental floss or a length of the cheesecloth can be used to make the suppository easier to retrieve. If the garlic causes a burning sensation, this can be eased with the insertion of plain yogurt into the vagina.

Precautions to take while using garlic

Consumers will find a wide variety of garlic preparations on the market. Therefore, it is important to study manufacturers’ claims, talk to knowledgeable practitioners, and find out which formulations are most effective for a given condition.

Due to the high concentration of sulfur compounds in garlic, it should be avoided by those allergic to sulfur. Garlic inhibits clotting, thereby causing increased bleeding times. 

Hemophiliacs and those on anticoagulant medication should consult a physician before taking garlic on a daily basis. This caution also applies to individuals who are preparing to undergo surgery. Medicinal use of garlic should be discontinued for at least 1–2 weeks before surgery. 

HIV patients receiving protease inhibitor or combination therapy should check with their physicians before using garlic supplements, as garlic may interfere with the therapy’s effectiveness.

Possible side effects of garlic

Raw garlic can be very irritating to the digestive system. Excessive intake (usually, more than three or four cloves a day) can cause bloating, gas, cramping, diarrhea, and may even damage the red blood cells.

When applied to the skin, garlic may cause itching, redness, and swelling. Garlic that is cooked, aged, or made into pills is not nearly as harsh on the system. However, these forms may not be as suitable as raw garlic in treating some conditions, particularly infections.

Garlic travels through the lungs and the bloodstream, giving a pungent garlic odor to the breath, skin, and perspiration. The odor will be present for at least 4–18 hours, sometimes even when so-called odorless garlic pills are used.

Interactions

Garlic does well when combined with coltsfoot or lobelia for treating asthma and bronchitis. Although onion is not as potent as garlic, it has similar actions, and the two often are combined. Use of garlic is contraindicated in individuals using the anticoagulant drug warfarin or certain HIV therapies.
