Toxicity is often associated with inherently dangerous or synthetic substances, while familiar foods, herbs, medicines, and household ingredients are generally perceived as safe. However, the fundamental principle of toxicology is that the effect of any substance largely depends on its dose. This article explores the concept that ?the dose makes the poison? through several everyday examples, including water, salt, caffeine, spices, herbs, tea, garlic, lemon juice, and bananas. It highlights how substances that may provide nutritional or beneficial effects at appropriate levels can produce adverse effects when consumed excessively or inappropriately. The article also examines common misconceptions surrounding natural products, vitamins, herbal and Ayurvedic preparations, medicines, and traditional home remedies, emphasizing that natural origin does not inherently guarantee safety. Particular attention is given to the growing influence of health-related misinformation on social media and the tendency to follow unverified recommendations. By connecting fundamental toxicological principles with familiar experiences, this article aims to promote greater awareness of dose-dependent toxicity and encourage rational, informed, and responsible consumption of everyday substances.
