I Built a "Lethal Dose" Calculator for Herbs — Here's What LD50 Data Reveals About Safety

I Built a "Lethal Dose" Calculator for Herbs — Here's What LD50 Data Reveals About Safety We've all heard "natural is safe." But is it? How much green tea extract would actually kill you? What about that St. John's wort supplement? I built a free Lethal Dose Calculator at Botánica Andina to answer this question using LD50 data — the scientific measure of what kills 50% of a test population. The results are surprising. What is LD50? LD50 = "Lethal Dose, 50%" — the dose that would kill half the people who take it. It's measured in mg/kg of body weight. Lower LD50 = more toxic. Substance LD50 (mg/kg) What This Means Caffeine 192 ~15g for 150lb person = 100+ espressos Nicotine 0.5 ~75mg for 150lb person = 1-2 cigarettes (pure) Water 6,000 ~450g for 150lb person = ~18 liters The Calculator The tool takes: Your body weight A herb/supplement from the database (25+ substances) The form (capsule, tea, extract) And calculates: Lethal dose in your unit of choice Number of doses to reach it Safety
