Garlic
Garlic — ce que la monographie européenne soutient réellement, ce à quoi ce n’est pas destiné, la forme et la durée prévue, les effets indésirables, et le 3 interaction médicamenteuses documentée.
Ceci est une page de référence, pas un diagnostic ni une ordonnance. Les produits à base de plantes sont de la vraie pharmacologie : effets, effets indésirables et interactions. Dites à votre médecin et à votre pharmacien tout ce que vous prenez, thés et compléments compris, et n’arrêtez ni ne changez jamais un médicament prescrit à cause de ce que vous lisez ici.
Ce que c’est
Allium sativum L. — bulb (Allii sativi bulbus)
Noms locaux dans la région que ce site dessert :küüslauk (ET) · valkosipuli (FI) · чеснок (RU).
Groupé ici sous Kitchen spices with a safety story. Position réglementaire :EU herbal monograph — traditional use; the indications concern mild circulatory complaints.
Ce que les preuves soutiennent
L’indication enregistrée :Relief of symptoms of mild circulatory complaints, in traditional-use preparations. Not the treatment of cardiovascular disease.
Garlic's medicinal reputation rests on allicin, which does not exist in an intact clove: it forms when alliin meets the enzyme alliinase as the clove is crushed or chopped, and it is unstable from that moment. This single fact explains why aged garlic extract, garlic oil macerate, dried powder and enteric-coated tablets all contain different compounds and cannot be compared with one another or with a clove in a pan. On the outcomes people buy it for — cholesterol and blood pressure — reviews find at most modest effects, inconsistent across preparations, and nothing that substitutes for treatment where treatment is indicated. What is clinically solid is the other side: garlic inhibits platelet aggregation, which is why it sits on surgical stop-before-your-operation lists.
C — Traditional use only Plausible from thirty or more years of use, which is what a traditional-use registration means. No clinical evidence was required and none has settled it.
Ce à quoi ce n’est pas destiné
High cholesterol or high blood pressure as a replacement for treatment, and infections. Raw garlic applied to skin as a folk remedy for warts or infections causes chemical burns — this is a documented and entirely avoidable injury.
Forme, force et durée
Fresh and cooked cloves as food, dried powder tablets, aged garlic extract, oil macerates and enteric-coated preparations. Odour-free products have usually removed the compounds responsible for the effects as well as the smell.
Durée.Culinary use is food. Supplement courses should be paused before planned surgery.
Aucun chiffre en grammes n’apparaît sur cette page exprès. La partie de plante, le solvant d’extraction et le rapport drogue-extrait définissent ensemble une préparation, et un nombre pris à l’une ne décrit pas l’autre. Le raisonnement est exposé sur le hub ; la quantité qui s’applique à vous est celle imprimée sur le paquet que vous tenez, et un pharmacien la lira avec vous.
Effets indésirables
Breath and body odour, heartburn, stomach upset and wind. Contact dermatitis in people who handle raw garlic regularly, such as cooks. Chemical burns from raw garlic applied to skin.
Qui devrait l’éviter
Culinary amounts are fine in pregnancy. Supplement amounts are not established. Stop supplements before surgery.
Interactions avec les médicaments
| Médicament ou substance | Ce qui est décrit |
|---|---|
| Anticoagulants and antiplatelets (warfarin, DOACs, aspirin, clopidogrel) | Antiplatelet activity adds to warfarin, DOACs, aspirin and clopidogrel. Case reports of bleeding exist. Supplement amounts matter far more than what goes in the pan. |
| HIV and hepatitis C antivirals | A documented interaction with the HIV medicine saquinavir, in which garlic supplements substantially reduced its blood level, is why garlic supplements are flagged specifically in HIV care. |
| Planned surgery and anaesthesia | Stop garlic supplements before planned surgery and tell the surgical team you have been taking them. |
La vue inverse — partir du médicament plutôt que de la plante — est dans la référence des interactions médicaments, aliments et alcool, et résumé pour chaque plante de ce site.
En tant qu’aliment
Celui-ci est aussi en cuisine, donc les chiffres nutritionnels valent d’être à côté de la pharmacologie : voir la page de données alimentaires pour calories et nutriments pour 100 g et par portion. Les quantités culinaires et les préparations médicinales sont des expositions différentes, et la différence est souvent toute l’histoire de sécurité.
