Advil, also known as ibuprofen, is a nonsteroidal anti-inflammatory drug (NSAID) that is commonly used to relieve pain, inflammation, and fever. According to the National Health Service (NHS) [3], it is important to be cautious when taking ibuprofen with other medicines and herbal supplements because they can interact with each other and cause harmful side effects.

One herbal supplement that may interact with Advil is St. John's wort. According to a study published in the Journal of Clinical Psychopharmacology [2], St. John's wort can reduce the effectiveness of ibuprofen by increasing its metabolism and reducing its absorption in the body. This can lead to decreased pain relief and increased risk of side effects.

Another herbal supplement that may interact with Advil is ginkgo biloba. According to Drug Patent Watch [1], ginkgo biloba can increase the risk of bleeding when taken with NSAIDs like ibuprofen. This is because ginkgo biloba can inhibit platelet aggregation, which is necessary for blood clotting.

Other herbal supplements that may interact with Advil include garlic, ginger, and turmeric. These supplements can also increase the risk of bleeding when taken with NSAIDs [3].

It is important to talk to a healthcare provider before taking any herbal supplements with Advil or any other medication. They can provide guidance on the potential risks and benefits of combining these substances and help determine the best course of treatment for an individual's specific needs.
