Harm from use

It is rare to hear that garlic, in addition to undeniable benefits, can have adverse effects. Everybody knows about persistent bad breath after eating garlic, but it is not dangerous for the body. For a healthy person, undesirable effects can occur only with excessive and frequent use of garlic. But there are categories of people who should eat it with care, or even abandon this sharp product, especially in its raw form.

So, fresh garlic must be abandoned to those who suffer from diseases of the digestive system. Garlic phytoncides have a high toxicity, after entering the stomach, garlic irritates its walls and increases acidity. Also, an excessive amount of garlic damages the mucous membrane of the stomach and intestines. Unpleasant consequences in this case: heartburn, abdominal pain, nausea.

In small quantities, garlic has a beneficial effect on the heart and blood vessels, thins blood. But with such problems as ischemia, varicose veins, hemorrhoids, thrombophlebitis and chronic hypertension, you can eat garlic after consulting with your doctor, since blood-thinning drugs are usually prescribed for such diseases, and combining them with garlic is undesirable. The worst development in this case is the onset of internal bleeding.

Allergy sufferers that react to foods should be wary of garlic as a product that has aggressive organic compounds. It also happens that a person who is not allergic and previously calmly consumed garlic, at one moment begins to feel bad after taking it. Unpleasant effects of allergic reactions: diarrhea, flatulence, sneezing, watery eyes, runny nose, skin rash, swelling and, as a last resort, asphyxiation.

In home cosmetology, garlic is used as a means to cleanse acne, to fight acne, warts, papillomas, mosquito bites. Gruel or juice rub problem areas and sometimes leave for a long time, and then they are surprised that the skin in the treatment area swells, turns red and becomes irritated. To avoid unpleasant burns, the contact time of the skin and caustic mixture should not exceed 7-10 minutes.

According to some scientists, garlic adversely affects the brain. Sulfanyl-hydroxyl ion, a reactive toxic radical, is able to easily overcome the meninges and desynchronize brain waves. This leads to short-term distraction, inattention, reduced reaction, a weak headache. For these reasons, it is not recommended to take garlic to people of professions that require instant reaction and long-term concentration, for example, pilots and drivers before flights.

Cooking methods

Garlic is a versatile vegetable that can be eaten raw, canned, roasted, dried, boiled and fried. Consider some methods of its preparation and therapeutic combinations with other products.


Garlic with honey and lemon to enhance immunity . In the juice of 1 lemon, add the juice of two garlic heads, mixed with 500 gr. honey On the day, two times eat 1 tbsp. spoon before a meal.

Garlic with milk to strengthen the immune system . In a glass of preheated milk, add a few drops of squeezed garlic juice. Milk reduces the pungent smell of garlic.

Pickled garlic retains most of the nutrients, but is devoid of unpleasant taste and aroma. Marinating the plant can be as whole heads, and individual brushed cloves; both hot and cold brine.

Roasted and baked garlic also loses its specific smell and spice, partially preserving the vitamins and trace elements. Peeled garlic are chopped into thin petals. On a quiet fire, heat the pan, pour vegetable oil. When it heats up, put garlic pieces in it for 2 minutes, stir constantly. If the oil is very hot, then the vegetable will be immediately charred. Roasted garlic has a mild flavor, as such it can be eaten in greater quantities than raw. Roasted garlic can be put in any dishes – sauces, salads, soups.

Beets with garlic are prepared to cleanse the body. For salad take boiled or baked beets, at least – raw, garlic, usually – fresh. Grated beets with garlic are mixed, salted to taste, seasoned with sour cream or mayonnaise. You can vary the salad with nuts or dried fruits. With a low-calorie diet, a fatty dressing can be replaced with vegetable oil or low-fat yogurt.

Carrots with garlic are cooked with the same ingredients as beets, only carrots are used primarily in raw form. Carrots are known to be rich in vitamins and useful elements.

Raw garlic is not recommended to be swallowed whole, although some medicine men advise it to sick people. There will be no benefit from this. It should be chewed thoroughly, then a positive effect is achieved.

Dried crushed garlic contains the same elements as raw. It is added to any dishes, used as seasoning.

From the foregoing, it follows the conclusion about the indisputable benefits of garlic to strengthen the immune system, in the fight against colds, with beriberi. But for this you need to take into account the state of health and the dosage of a sharp vegetable.
