Puis-je prendre des suppléments d'ail et de ginseng ensemble ?

Guide d'interaction médicamenteuse

Taking garlic supplements and ginseng together may increase your risk of bleeding or bruising. Both of these herbal remedies can thin the blood, and using them at the same time can make this effect stronger.

Pourquoi cela se produit

Both garlic and ginseng have 'antiplatelet' properties. This means they both interfere with how your blood cells (platelets) clump together to form clots. When combined, they have an additive effect, making it harder for your blood to clot if you injure yourself.

Use this combination with caution. If you notice unusual bruising, nosebleeds, or bleeding gums, stop taking the supplements and speak to your GP. You should stop taking both garlic and ginseng at least two weeks before any planned surgery or dental work to prevent excessive bleeding. If you are already taking prescription blood thinners (like warfarin or aspirin), do not take these supplements without consulting your doctor first.

Surgery or dental procedures

Both garlic and ginseng can thin your blood and increase the risk of serious bleeding. You must stop taking these supplements at least 2 weeks before any planned surgery or dental work.

Taking blood-thinning medications (e.g., warfarin, clopidogrel)

Both garlic and ginseng supplements can significantly increase the effect of blood-thinning medicines, making you more likely to bruise or bleed dangerously.

Diabète

Ginseng can significantly lower your blood sugar levels. If you take insulin or other diabetes medications, using ginseng may cause your blood sugar to drop dangerously low (hypoglycaemia).

Alcool

It is best to avoid or strictly limit alcohol when taking these supplements. Ginseng may affect how your body processes alcohol, potentially lowering blood alcohol levels but increasing the risk of headaches or sleep disturbances. Garlic supplements can thin the blood; alcohol also has a mild blood-thinning effect, which could theoretically increase the risk of bruising or bleeding.

Caféine (Café, thé, boissons énergisantes)

Ginseng can act as a stimulant. Combining it with caffeine may increase the risk of side effects such as a racing heart (tachycardia), high blood pressure, nervousness, and insomnia. It is best to limit caffeine intake while taking ginseng.

Foods high in Vitamin K (Leafy greens, broccoli)

Ginseng may interfere with the effectiveness of blood-thinning medications like warfarin. While the interaction with Vitamin K-rich foods is indirect, you should maintain a consistent intake of these foods and inform your doctor if you are taking ginseng alongside anticoagulant therapy.
