Harm and benefits of garlic: how does the plant affect the heart and blood vessels, how to treat with it?

While some doubt the benefits of garlic, others eat a couple of cloves before lunch, and you know, they really rarely get sick. The beneficial properties of vegetable segments, feathers and arrows are a scientifically proven fact, confirmed by numerous studies.

Then why are many people interested in how garlic affects the heart? Did the famous vegetable really give someone a heart attack or, on the contrary, help alleviate the condition of cardiovascular diseases? Let's look at this important issue for many.

Garlic + heart = vitality

does garlic affect the heart

You don’t need to have a medical education to understand: a person’s health and general well-being primarily depends on the state of the cardiovascular system. The engine stalls and problems with blood pressure, breathing, and hematopoiesis begin, and this is only the beginning of the list of pathologies that heart failure leads to.

Many people know that, for example, the inhabitants of the Caucasus have great respect for garlic and at the same time are distinguished by enviable health and longevity. And around 1600 BC. e. Egyptian workers who built the pyramids rebelled only because they were no longer given this vegetable. It is unlikely that they knew whether garlic affected the heart, but they clearly understood that they could not survive without it.

The ancient Indians were the first to discover the healing properties of garlic. Because of the pungent odor, they simply did not eat it or add it to food, but used it specifically for medicinal purposes.

First, man discovered the healing power of the aromatic vegetable against infections and parasites. And modern research into the composition of the vegetable crop has helped us understand whether garlic is harmful or beneficial to the heart.

Can I use it?

Arrhythmia

This is a disease that manifests itself as rapid heartbeat or irregular heartbeats. Treating yourself with traditional medicine can be a very dangerous activity, but it is not useless if you inform your cardiologist. He will be able to help you create the right recipe with an individual dosage.

It’s the same with garlic – if used frequently and in large quantities, it can cause even more harm. But with the right dosage, it will be very beneficial for blood vessels and the heart.

Ischemia

This is a disease in which the blood supply to the heart is reduced due to vasoconstriction or blockage, which causes damage to myocardial tissue. Garlic, in this case, is an excellent addition to the treatment. Since its main functions include dilating blood vessels and removing cholesterol, using folk recipes with garlic for ischemia will be very useful. But you need to take into account the body’s individual reaction to this product.

Heart attack

A form of coronary heart disease, accompanied by increased necrosis of myocardial tissue due to complete or partial insufficiency of blood supply. Eating garlic immediately after a heart attack is undesirable , since the substances in this product excite the body’s nervous system. During remission, with the permission of your doctor, you can reintroduce this product into your diet.

Heart failure


A disease in which myocardial function is impaired, i.e. The cardiovascular system is not able to provide sufficient blood circulation in the human body. Garlic will be useful in treatment with folk remedies, but will not replace full treatment. Dosages and suitable prescriptions should be asked from your doctor.

For serious heart diseases, this product can bring both benefit and harm. Eating this vegetable has a positive effect on a person’s blood vessels and blood pressure, but people with heart problems should not abuse this product (read about how to use garlic with high and low blood pressure here). It must be remembered that it is effective even in small doses.

Unfortunately, there are no clear instructions for using garlic and there is no precise definition of whether it is worth consuming. For heart diseases, there are folk recipes that help improve the patient’s condition , but this is not a cure; it will not completely cure the disease.

Vitamins and minerals for the heart

how garlic affects the heart and blood vessels

For heart patients, vitamin B5 (pantothenic acid) must be prescribed as part of therapy. 100 g of garlic contains 0.6 mg of this vitamin. However, it contains the most vitamin C (about 33 mg). And ascorbic acid deficiency is known to lead to fragility of blood vessels.

Also among the vitamins and minerals in garlic that have a beneficial effect on the functioning of the cardiovascular system, it is worth noting:

  • Pyridoxine (vitamin B6). Necessary for people suffering from coronary atherosclerosis.
  • Nicotinic acid (vitamin PP). Useful for ischemic cerebrovascular accidents.
  • Potassium. Ensures normal functioning of the heart muscles.
  • Magnesium. It has a vasodilating effect and supports myocardial function.
  • Selenium. One of the useful components that make up myocardial proteins.

Benefits, harms and composition


Irrational and excessive consumption of vegetables can cause harm to the body.

Just like any other, even the mildest and safest remedy, garlic has a number of both positive and negative properties. But in fairness, it should be noted that the negative qualities of this vegetable manifest themselves mainly when it is abused or the wrong use of products prepared on its basis.

As for the positive properties, there are more than enough of them, and this is due to the rich chemical composition of the product.

CompoundBeneficial featuresPossible harm
Proteins fats carbohydrates.Increases the body's immune strength and its resistance, that is, resistance to pathogenic microorganisms.Garlic contains a small amount of toxic substances, the use of which can cause an allergic reaction.
Vitamin complexes: vitamins B, A, C, E and others.Helps normalize blood pressure, cleanses blood vessels from harmful cholesterol, increases their elasticity and neutralizes fragility.Against the background of existing disturbances in the functioning of the digestive tract, bloating and heartburn may occur.
Essential oils.Normalizes metabolic processes and stimulates blood flow.The vegetable can cause harm to the body due to the presence of diseases of the excretory system that occur in an acute form.
Ascorbic acid.Improves the supply of nutrients and oxygen to tissues and organs.Headaches, dizziness, weakness and nausea may occur.
Phytoncides.Normalizes sleep, prevents insomnia, increases performance.The product is harmful for use in diseases of the digestive tract in the acute stage.

Garlic has a general strengthening effect, helps the body cope with diseases of an infectious and viral nature, helps normalize metabolic processes, and is a preventative against colds. It is also important that the price of such a natural medicine is more than affordable.


You can use folk remedies only if there are no contraindications.

Advice! It is important to remember that prolonged and regular consumption of vegetables can have a negative effect on the body if there are contraindications or due to abuse. In any case, the consumption of garlic-based products intended to cleanse blood vessels should be recommended by a doctor.

Flavonoids, amino acids and a unique component - allicin

harm and benefits of garlic for the heart

Studying the properties of this onion plant, you involuntarily gain respect for people who have experienced whether garlic affects the heart and blood pressure. After all, its composition is a storehouse of substances essential for the cardiovascular system. It befits:

  • saponins, which have a pronounced anti-sclerotic effect;
  • chlorogenic acid, which reduces the level of bad cholesterol in the blood;
  • ferulic acid has a cardioprotective effect;
  • rutin (a glycoside of the vitamin P group) improves vascular permeability and lowers blood pressure.

All these components also have a beneficial effect on other vital processes in the body. But the vegetable contains an essential oil, which, when the integrity of the clove is damaged, releases a unique substance - allicin, which gives it a burning taste and aroma. Using the example of the action of this component, it is explained how garlic affects blood pressure and the heart.

Use for various diseases

For some diseases associated with the heart, garlic is recommended for use, which was confirmed by one large-scale study . In order to understand the benefits and harms of this product, you need to study its effect on the heart in various diseases.

Is it possible to eat it if you have arrhythmia?

Arrhythmia manifests itself in the disruption of heart rhythms, that is, rapid heartbeat, which occurs for many reasons.

Excessive consumption of garlic is contraindicated, but with regular addition of this product in small quantities, arrhythmia may recede , which is associated with the increased content of nutrients and vitamins in the vegetable.

Properly consumed garlic, with this type of disease, cannot harm the body, but, on the contrary, will have a strengthening effect.

For hypertension

Garlic is also useful for hypertension, as is motherwort or hawthorn. Some scientists claim that blood pressure is reduced by 7-10 units, while others claim that the effect of taking this product is very insignificant.

Fresh garlic delivers the greatest effect than the product that is produced on its basis, that is, capsules and other food additives. This is explained by the fact that they contain less allicin than the fresh product.

What is allicin?

does garlic affect the heart and blood pressure?

A whole clove of garlic contains alliin sulfoxide, located in the cytoplasm, and the enzyme allicinase, which is part of the vacuoles of plant cells. When garlic cloves are cut or crushed, the molecules of these substances are broken down and interact to form allicin. When heated, this compound is destroyed, so there will be no benefit for the heart from boiled, fried or pickled garlic.

And if you eat a raw clove, the active ingredients of allicin immediately bind to red blood cells. No matter how strange it may sound, hydrogen sulfide is formed as a result of a biochemical reaction.

By the way, myocardial infarctions are always accompanied by a deficiency of endogenous hydrogen sulfide. An acute shortage of this substance is also observed in people suffering from Parkinson's and Alzheimer's disease.

And now the most important thing: how does garlic affect the heart, blood vessels and blood pressure, if as a result it releases a substance that is commonly associated with the smell of rotten eggs?

Does it matter how it's cooked?

Doctors advise eating it before meals in the morning or during the day, preferably raw, chopped (you can read about how you can eat garlic without chewing it and what time of day it is best to eat it here, and from this article you will learn about the benefits of eating this vegetable on an empty stomach - benefit or harm to the body). Beneficial substances retain their activity for no more than 25 minutes after mechanical action on garlic, so it is worth consuming immediately. A product that is dried or processed into powder does not contain any vitamins and does not provide any benefits , only the smell and taste remain.

Mechanism of action of hydrogen sulfide

By penetrating the walls of blood vessels, hydrogen sulfide reduces their tension and improves blood flow. As a result, blood pressure decreases, oxygen flow increases and, as a result, the load on the heart is significantly reduced.

In addition, hydrogen sulfide reduces total blood cholesterol levels and increases the concentration of high-density lipoproteins (HDL), which have pronounced antiatherogenic properties.

Therefore, regular consumption of garlic as a prevention of atherosclerosis and arterial hypertension is a scientifically based and proven fact.

In simple terms, how garlic affects the heart and blood vessels:

  • expands the lumens of blood vessels;
  • cleanses and thins the blood;
  • removes harmful cholesterol;
  • normalizes blood pressure;
  • prevents disruption of the blood supply to the myocardium (coronary heart disease), the development of thrombosis, heart attacks and strokes.

For preventive purposes, the vegetable can and should be used from a young age. And “garlic therapy” will help many in the complex fight against existing pathological conditions.

Garlic preparations in the pharmacy, garlic as a dietary supplement

The use of garlic oil is especially important for viral diseases and colds. Regular use of the substance normalizes appetite, improves the microflora of the stomach and intestines, suppresses pathogenic bacteria, and has a positive effect on the elasticity of blood vessels and heart function.

All the benefits of garlic can be obtained both from natural products and pharmaceutical preparations. In a sense, garlic capsules are even healthier, since the easily degradable substances in them are reliably protected from gastric juice by the walls of the capsule.

Who needs to start eating garlic?

how garlic affects blood pressure and heart

It’s not for nothing that in the old days they said: “Garlic and onions cure seven illnesses.” Our ancestors probably understood how garlic affects the heart, they grew it in whole fields, ate it constantly and lived to a ripe old age.

Today, when the quality of water and food leaves much to be desired, eating vegetables will greatly help people at risk for cardiovascular diseases. You should start eating garlic if you have the following pathologies:

  • frequent headaches;
  • overweight;
  • diabetes;
  • arterial hypertension;
  • diagnosed atherosclerosis;
  • varicose veins.

Many people like the taste of aromatic cloves, so you can eat 2 cloves for lunch with benefit and pleasure. However, for true gourmets and those who do not like to breathe garlic, there are alternative options.

4 more properties of this vegetable

In addition to its positive effect on cardiovascular activity, garlic has the following effects on the body:

  1. this plant counteracts carcinogens, that is, the beginnings of cancer;
  2. has benefits for the digestive system, that is, it restores balance in the microflora and destroys harmful bacteria;
  3. affects the state of male potency, substances in the product help cope with dysfunction and promote erection;
  4. Allicin in the plant eliminates toothache if you apply a squeeze of it to the affected area in the mouth.

Garlic, along with other fruits and vegetables, is endowed with a large list of useful and nutrients necessary for the normal functioning of the body.

The list of components of the aromatic product includes vitamins (D, groups B 1 and 3, C), mineral salts, phosphoric and sulfuric acid, as well as silicic acid, iodine, potassium and magnesium. Additionally, there are such beneficial substances as ajoene, lysine, phytoncides, phytosterols, allicin, and inulin. Due to the natural origin of all components, they are quickly and fully absorbed into the walls of the stomach, entering the systemic bloodstream and exerting a positive effect on the heart muscle.

Contained polysulfites, entering the human body, are processed into hydrogen sulfide. Thanks to the processes taking place, the following effects occur:

  • The elasticity of blood capillaries increases;
  • Blood circulation is activated;
  • Congestion in the veins is eliminated;
  • Leads to normalization of blood pressure.

Allicin comes into contact with the red blood cells of the bloodstream, provoking a chemical reaction. Due to contact, hydrogen sulfide has a positive effect on blood capillaries. The lumen increases, stimulating an increase in the speed of blood movement through the vessels and veins, and the tension in the vessel walls decreases. The ongoing processes significantly affect the heart muscle, reducing the load on it.

Recipes with garlic for improving the cardiovascular system

Garlic with lemon

There are many options for preparing garlic tinctures, nutritional mixtures and drinks to cleanse blood vessels. We will focus on those that, according to people’s reviews, turned out to be the most effective:

  1. A large head of garlic (about 12 cloves) is crushed and added to 0.7 liters of good red wine. Leave in a dark place for 2 weeks, shake at least 2 times a day. Take 1 tsp of strained wine. 3 times a day for 30 days.
  2. Peel 1 head of garlic, remove the seeds from 1 large lemon, add 100 g of honey and mix in a blender. Keep for 7 days in a glass jar at room temperature, filter through a fine sieve. Take 1 tsp. 2 times a day for at least a month. The mixture is stored in the refrigerator.
  3. Take 500 g of cranberries, 100 g of garlic cloves, 250 g of honey, mix in a blender. After 12 hours, you can start taking 1 tsp of the tasty and healthy mixture. 2 times a day. The course of treatment is at least one and a half months.

Recipes with honey are also suitable for people with high blood sugar. For type 2 diabetes, you are allowed to consume up to 2 tablespoons of the sweet ingredient per day. However, before starting therapy, it is better to consult with your treating endocrinologist.

Despite how garlic affects the heart and how beneficial it is for blood vessels, some people, unfortunately, cannot eat this vegetable.

How does garlic affect the heart - should people with heart disease eat it?

Garlic is considered a popular folk remedy for treating diseases. Scientists are confident that regular consumption of the product strengthens the immune system and prevents the development of viral infections in the body. Not long ago, the benefits of garlic for both the heart and blood vessels were proven. However, the product also causes harm. Let's figure out how garlic affects the heart and other organs.

What are the benefits of garlic?

Garlic is common in alternative medicine and herbal medicine. In its raw form, the plant helps fight colds, skin diseases, and heart ailments.

Fights bad cholesterol in the blood. Garlic juice is used as an effective remedy against harmful insects.

The stronger the taste, the more sulfur compounds it contains, which indicates that it has a pronounced medicinal effect.

Why should you eat garlic? Garlic juice has an amazing ability to fight microorganisms. It kills various types of bacteria that can cause diseases.

Does garlic affect the heart?

Polysulfides contained in the plant are transformed into hydrogen sulfide in the human body. This substance improves the elasticity of vascular walls, activates blood circulation, and lowers blood pressure.

Doctors have confirmed the beneficial effects of garlic on the heart and blood vessels. Particles of the substance allicin, which is part of the plant, come into contact with red blood cells. A chemical reaction begins, during which hydrogen sulfide is released. It reduces the tension of the vascular walls and increases blood flow.

Hydrogen sulfide has an unpleasant odor. However, in small quantities the element plays a huge role in the life of blood cells. Thanks to hydrogen sulfide, the lumen in the vessels increases, which increases blood supply and reduces the load on the heart muscle. Regular use of the product will protect blood vessels from atherosclerotic formations, and the heart muscle from heart attack.

Garlic juice contains a high concentration of ascorbic acid, manganese and vitamin B6. These elements are useful for strengthening the heart and vascular system. But there are indisputable facts that garlic is harmful.

Harmful effects of garlic

Garlic contains toxic trace elements. Some people are immune to them, while others may develop severe allergies and heart attacks.

Even healthy people are not recommended to consume garlic before bed. The plant causes heartburn and leads to indigestion.

There is no need to eat garlic if you have diseases of the nervous system or heart. Substances present in the product dilate blood vessels and can cause heart pain. Sometimes this leads to suffocation, increased heart rate, abdominal pain, and a feeling of nausea. All this may be accompanied by dizziness, migraines, and in rare cases, clouding of reason.

Important! All garlic elements spread throughout the human organs with lightning speed. In addition to increasing the lumen of blood vessels, they can corrode mucous membranes and interfere with the normal functioning of the cardiovascular and genitourinary systems.

The product will not cause a heart attack, however, rapid heartbeat and tachycardia occur frequently, especially in those who suffer from heart pathologies, so it is reasonable to avoid garlic.

Garlic mixture with honey and lemon

A common remedy for promoting health and cleaning blood vessels is a composition of honey, lemon juice and garlic. Each ingredient is useful in its own way. For example: lemon increases efficiency, improves memory, protects the body from colds and infectious diseases.

Garlic helps cleanse blood vessels, prevents the development of tumors, and makes blood vessels elastic. And honey is useful for every system in the human body, from the cardiovascular to the genitourinary.

When products are combined in one recipe, the result is a real potion for youth and health. To prepare, grind two lemons with peel in a meat grinder, add two chopped garlic heads, pour in 100 grams of honey. Store the product in the refrigerator and use every day before meals.

Garlic for the heart with honey

The recipe is simplified, intended for people suffering from high acidity. Therefore, lemon is excluded. To prepare the mixture, take 200 grams of peeled and grated garlic and 300 grams of honey. Mix the components and place in a dark place for 7 days. After this, take one tablespoon before meals. The course of treatment is one and a half months.

Who can harm garlic?

Many people know that they should not eat spicy foods, including garlic, due to the risk of irritating the mucous membranes. You should completely abandon vegetables or eat them with caution in the following conditions:

  • kidney diseases;
  • gastrointestinal pathologies;
  • anemia;
  • cholelithiasis;
  • low pressure.

Pregnant women should avoid garlic in the 3rd trimester. Anyone who has no contraindications can safely begin the prevention of cardiovascular diseases, but one unresolved issue remains to be clarified.

Contraindications to eating garlic

Garlic, which is beneficial for the heart, may be contraindicated in acute kidney diseases; it is also not recommended for those suffering from epilepsy and pregnant women. During the treatment, the kidneys experience a heavy load, since they mainly remove toxins accumulated in the body. To make their work easier, it is advisable to move more and drink about 2.5 liters of water per day. You should refrain from drinking cocoa, coffee, strong tea, seasonings and hot spices. Alcohol, which causes serious complications, should be completely avoided.

Why does garlic hurt my heart?

Garlic cloves

Vasodilation and blood flow to the heart can actually cause chest pain and rhythm disturbances, tachycardia and even a heart attack. Therefore, in people with any diagnosed heart disease, for example, cardiosclerosis, arrhythmia, ischemic heart disease, endocarditis, the use of garlic should be agreed with a cardiologist.

If a healthy person who eats a salad with a vegetable feels nauseous and has chest pain, he should definitely go to the doctor. This is how garlic affects the heart: it can tell you that something is not right with the “engine”. Timely detection of diseases will help to avoid the unpleasant consequences of chronic pathologies.

Harmful properties of garlic

Many people know that they should not eat spicy foods, including garlic, due to the risk of irritating the mucous membranes. You should completely abandon vegetables or eat them with caution in the following conditions:

  • kidney diseases;
  • gastrointestinal pathologies;
  • anemia;
  • cholelithiasis;
  • low pressure.

Pregnant women should avoid garlic in the 3rd trimester. Anyone who has no contraindications can safely begin the prevention of cardiovascular diseases, but one unresolved issue remains to be clarified.

Scientists have carefully studied the composition of garlic for several years. Thanks to experiments and comparisons, it was established that garlic contains toxic substances. In some people they do not cause side effects, in others they can cause an allergic reaction or even heart attacks.

You should not eat garlic if you have any abnormalities in the nervous and cardiovascular systems. The substances contained in its composition significantly dilate blood vessels, which can cause attacks of suffocation, rapid heartbeat or nausea. Such symptoms are most often accompanied by headache, dizziness and impaired perception of the outside world.

The components contained in garlic spread almost instantly throughout the human body. In addition to dilating blood vessels, they can corrode mucous membranes and disrupt the functioning of the heart, liver and kidneys. Garlic cannot cause a heart attack, but it plays an important role in the appearance of tachycardia and arrhythmia.

Please note that garlic contains many toxic substances. That is why an excess of it in the diet can lead to increased cholesterol levels. Toxins not only have a detrimental effect on the body, but also cause disorders of the nervous system, sleep disturbances and digestion.

Is garlic good or bad? There is debate among scientists about the benefits or harms of the product; some believe that garlic can only bring positive results, but some argue that it contains so many toxic substances that they can lead to disastrous consequences. However, this controversial plant proves that when consumed for 3-4 months, the walls of blood vessels dilate, thereby destroying cholesterol.

But you should not eat more than 2 cloves a day, or before bed, as this can lead to problems with the stomach and intestines even in a healthy person (you can read about what will happen to the body if you eat garlic every day find out here, and from this material you will learn why and how to properly dissolve this vegetable in the morning).

How does garlic affect the body and what are the benefits of garlic? When allicin, a component of this vegetable, enters the body, a reaction occurs. As a result, hydrogen sulfide is formed. It is able to lower blood pressure by quickly distributing beneficial substances throughout the body. This helps reduce the load on the heart. But there are times when it can cause harm.

If a person has serious heart disease, consuming this product may cause:

  • chest pain;
  • suffocation, migraines;
  • general poor health.

Attention! People with gastrointestinal diseases need to be careful, as the toxic substances this product contains can cause pain in the abdominal area.

We talked in detail about how garlic affects the gastrointestinal tract and why the stomach hurts after eating it in this article.

In addition to the components of the aromatic vegetable, it also contains toxic substances. Some patients with heart pathologies are sensitive to them, others do not perceive them. Side effects after consumption, for people who are prohibited from eating root vegetables, are the following:

  1. Heart attack;
  2. Severe allergic reaction;
  3. Increased frequency of myocardial contractions;
  4. Feeling of nausea;
  5. Painful discomfort in the digestive organs;
  6. Suffocation;
  7. Head pain and severe dizziness;
  8. Loss of reason for a short or long period of time.

In some situations, harmful toxins cause tachycardia or arrhythmia. The ongoing processes are possible if a patient with heart pathologies consumed a large dose of an aromatic vegetable at night. The root vegetable in a small volume stimulates the expansion of the lumen of blood vessels, then toxic microelements entering the bloodstream have the ability to quickly spread throughout the body.

The lightning-fast spread of harmful substances leads to a malfunction in the functioning of the myocardium. In addition, the increased volume of toxins leads to erosion of the inner mucous membrane of the capillaries, causing problems with the liver and kidneys.

Therefore, an increased volume of consumed product leads to the fact that garlic has a bad effect on the heart, stimulating an increase in cholesterol in the blood. In addition, toxins cause pain in the digestive organs, disruption of the nervous system and problems with sleep.

Composition of the product

Garlic, like other vegetables and fruits, is a storehouse of vitamins, despite different opinions regarding its taste. It contains various vitamins: B1, B3, as well as D and C. The beneficial substances inside garlic consist of mineral salts, calcium, magnesium and iodine, as well as sodium. There are three types of acid inside the product: phosphoric, silicic and sulfuric. In addition to the above substances, the cloves of this vegetable contain such useful components as:

  • allicin;
  • phytoncides;
  • inulin;
  • lysine;
  • phytosterols;
  • ajoene;
  • other vitamins and minerals.

The benefits of the internal composition of garlic are manifested in the action of these substances, and also in the fact that they are not obtained synthetically, but are created by natural conditions, which means they will be easier to absorb by the human body. Let us remind you that we have already reviewed 5 facts about the effect of onions on the heart and blood vessels.
