Good for the heart 

Garlic would help to regulate cholesterol by fighting what is called "bad cholesterol," which increases the risk of cardiovascular disease. It is therefore an indirect ally of the heart! In addition, it increases the fluidity of the blood, which reduces the formation of clots that can block the veins and arteries.

"Last thing, garlic effectively replaces antibiotics. It increases the level of antioxidant in the body.

True, the taste of raw garlic is unpleasant, certainly it gives an infectious breath, but will these disadvantages prevent you from using it for your well-being? Especially since these defects can be circumvented.

Dosage of garlic

1- Internally

Reduction of blood lipids, moderate hypertension and prevention of atherosclerosis (as a long-term adjuvant to dietary measures)

  • Fresh garlic. Consume 1 to 2 cloves (4 g to 8 g) per day.
  • Dried garlic. Take 0.5 g to 1 g per day.
  • Normalized extract (1.3% allicin, from 3.6 mg to 5.4 mg allicin per gram of powder). Take 200 mg to 400 mg three times a day.
  • Aged garlic. Take 600 mg to 900 mg daily. Note that in some studies, up to 7.2 g per day was used.
  • Garlic oil (steam distillation). Take 5 mg to 8 mg daily.

Respiratory tract infections (cold, cough)

  • Fresh garlic. Consume about 4 garlic cloves (16 g) per day.
  • Dried garlic. Take 2 g to 4 g, 3 times a day.
  • Dyeing (1: 5, 45% ethanol). Take 2 ml to 4 ml, 3 times a day.
  • Normalized extract (1.3% allicin). Take 800 mg to 1600 mg three times a day.

2- Externally

Fungal infections (athlete's foot, etc.)

  • Commercially available creams or gels based on ajoene, one of the ingredients of garlic (concentration of 0.4% to 1%). The cut and crushed bulb may also be used, but raw garlic can irritate the skin and mucous membranes and cause allergic reactions.



  • None known, except perhaps for people with porphyria, a very rare disease of blood metabolism (see History).
  • It is recommended, however, to avoid consuming large amounts of garlic (food or supplements) before and after surgery because of its anticoagulant effects that may increase bleeding. At the usual dietary doses (4 g per day), however, garlic does not present any danger before an operation 43 .

Side effects

  • Slight occasional gastrointestinal discomfort as a result of high consumption of garlic .
  • Some people may have difficulty digesting raw garlic .
  • Possible reactions of the skin or mucous membranes resulting from the topical application of fresh garlic .
  • The breath of the garlic eater gives off scents that are not always appreciated. Regular consumption of garlic promotes the formation of enzymes that help minimize these effluvia. Eating fresh parsley also helps to reduce bad breath.


With plants or supplements

  • The effects of garlic could be added to other herbs or supplements that thin out the blood or have anticoagulant effects.

With medication

  • The effects of garlic supplements may be added to those of blood thinners or anticoagulants. In healthy subjects, however, garlic did not interact with warfarin.

Opinion of our pharmacist

Modest, but numerous effects

Although the effects of garlic are modest, they are many. Because it affects all cardiovascular risk factors, it is an interesting complementary treatment for those affected. That is why Commission E, ESCOP and the World Health Organization recognize it as an adjunctive treatment for hyperlipidemia and atherosclerosis. It also has the potential to slow the progression of diabetes complications, another risk factor for cardiovascular disease.

The important points to remember in the use of garlic are the dose and the regularity. As mentioned in the sheet, choose either a standardized product of alliin or allicin or aged garlic. It must be eaten every day. Occasional use does not confer results. Interesting results in the prevention of cardiovascular disease appear after several months.

The consumption of food garlic is also recommended. It is an essential health food. On the other hand, to have a tangible therapeutic effect, you have to eat a lot, one pod or more per day, which can be difficult to do continuously.

On the shelves

As research has determined that allicin is one of the major components that could be attributed to some of the therapeutic effects of garlic bulbs and their derivatives, manufacturers are increasingly providing supplements based on extract d Garlic standardized in allicin.

In fact, most of the time, what is standardized in these products is the aline content. Indeed, the bulb of garlic as such does not contain allicin. Allicin is a highly unstable compound that forms when the algin contacts an enzyme, allinase . This happens when the garlic is milled or chopped.

Rather than talking about a standardized extract in allicin, it should be said that it is an extract whose potential for allicin is normalized. Thus, a product containing 1.3% alliin should normally provide a good dose of allicin, provided that the manufacturer has ensured that the allinase, naturally present in the bulb, is well preserved in the extract so as to Be released at the appropriate time to allow the production of allicin.

Similarly, the use of enteric coated tablets favors the formation of allicin in the intestines rather than in the stomach where it is likely to be destroyed by gastric juices, allowing it to exercise systemic activity. This type of tablet also reduces the smells causing bad breath, detracting from the potential for producing allicin.

Experts generally consider that a standardized supplement should provide 3.6 mg to 5.4 mg of allicin per dose and that it should be enteric-coated (or enteric coated) while dissolving completely before leaving the intestines, Otherwise the best of the extracts would be totally ineffective, which may have occurred in some clinical trials with negative results.

The aged garlic is made by a fermentation process in which the ally is transformed into a series of derivatives of which virtually no allicin is found. It is therefore odorless. It would not, however, be ineffective if we are to believe the few clinical trials in which this type of extract (mainly the Kyolic® product) was used. The dosage should, however, be greater than when fresh or dried garlic is used, whether it is standardized or not.

    Je consomme régulièrement de l'ail cru comme fortifiant , antifatigue . J'aimerais savoir si la consommation d'ail peut remplacer l'ingestion quotidienne d'un antiagrégant plaquettaire comme le "clopidogrel" .
    Merci pour une réponse .
