Medicinal plants and drug combos raise health concerns

Health experts warn that natural remedies and over‑the‑counter medicines can cause serious side effects and dangerous drug interactions. In Spain, pharmacist Roberto Collado Borell of Hospital Gregorio Marañón highlighted that plants such as St. John’s wort (hipérico) and ginkgo biloba may trigger severe reactions when combined with antidepressants, anticoagulants or aspirin. Similar safety concerns are echoed in Argentina, where a study led by Sofía Dell Orto at Universidad Nacional del Nordeste found toxic compounds in traditional digestive herbs, and in Mexico, where researchers at Universidad Veracruzana are evaluating the analgesic properties of chamomile and basil.

In Chile, university chemist Fernando Torres of the Escuela de Química y Farmacia de la Universidad Andrés Bello warned that common drug mixes—paracetamol, ibuprofen, psychotropic agents and antihistamines—are linked to intoxications, producing symptoms such as nausea, drowsiness and bleeding disorders. Both reports stress the need for professional guidance before using herbal products or combining medications, even those considered harmless.
