Garlic
Garlic — o que a monografia europeia realmente apoia, para que não é, a forma e por quanto tempo deve ser usado, efeitos colaterais e a 3 interação medicamentosas documentada.
Esta é uma página de referência, não um diagnóstico nem uma receita. Produtos herbais são farmacologia de verdade: têm efeitos, efeitos colaterais e interações. Conte ao médico e ao farmacêutico tudo o que toma, incluindo chás e suplementos, e nunca pare ou mude um medicamento prescrito por causa do que ler aqui.
O que é
Allium sativum L. — bulb (Allii sativi bulbus)
Nomes locais na região que este site atende:küüslauk (ET) · valkosipuli (FI) · чеснок (RU).
Agrupado aqui em Kitchen spices with a safety story. Posição regulatória:EU herbal monograph — traditional use; the indications concern mild circulatory complaints.
O que a evidência apoia
A indicação registrada: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.
Para que não é
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.
Forma, força e por quanto tempo
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.
Duração.Culinary use is food. Supplement courses should be paused before planned surgery.
Nenhum número em gramas aparece nesta página de propósito. A parte da planta, o solvente de extração e a razão droga-extrato juntos definem uma preparação, e um número tirado de uma não descreve outra. O raciocínio está no hub; a quantidade que se aplica a você é a impressa na embalagem que segura, e um farmacêutico lê com você.
Efeitos colaterais
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.
Quem deve evitar
Culinary amounts are fine in pregnancy. Supplement amounts are not established. Stop supplements before surgery.
Interações com medicamentos
| Medicamento ou substância | O que é descrito |
|---|---|
| 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. |
A visão inversa — começar pelo medicamento em vez da planta — está na referência de interações de medicamentos, alimentos e álcool, e resumido para cada erva neste site.
Como alimento
Este também está na cozinha, então os números de nutrição valem ter ao lado da farmacologia: veja a página de dados de alimentos para calorias e nutrientes por 100 g e por porção. Quantidades culinárias e preparações medicinais são exposições diferentes, e a diferença costuma ser toda a história de segurança.
