10 Popular Herbs That Can Dangerously Interact with Common Medications

Herbal remedies may seem safe and natural, but certain popular herbs can interact harmfully with medications, potentially leading to serious health risks.

The Medicines Evaluation Board (MEB), a trusted authority on drug safety, has identified 10 widely used herbs that should not be combined with specific medicines. These interactions can prevent proper drug absorption or accelerate breakdown, sometimes resulting in life-threatening situations.

Seemingly Innocent

MEB Chairman Prof. Dr. Ton de Boer warns: "Herbs may seem harmless, but they are not always so. The combination of medicines and herbal products is sometimes dangerous. It is therefore important that drug users know what the risks are and that they always inform their healthcare provider."
