Many of the most potent poisons are of natural origin. For example, hemlock and belladonna were historically used as medicines but contain alkaloids so toxic that even a small miscalculation in dosage can be fatal. Even modern herbal products that are commonly perceived as harmless can pose risks. For example, kava, a plant traditionally used for relaxation, has been associated with severe liver toxicity. St. John’s wort, often used to treat mild depression, can dramatically reduce the effectiveness of oral contraceptives and anticoagulants by altering liver enzyme activity. Ginkgo Biloba increases the risk of bleeding when taken with anticoagulants. Ephedra (Ma Huang), once a popular natural stimulant, was banned in many countries after causing numerous cardiac deaths. These examples highlight the fact that a compound’s natural origin does not equate to biological compatibility or safety. The distinction lies in how a compound interacts with the human body, not whether it is natural or synthetic.
