Insights Why Spices Are Called Plant Poisons: The Science Behind Flavor, Defense, and Human Adaptation
Spices are, in a biological sense, plant poisons. That may sound dramatic, but it is scientifically accurate. Plants cannot run, hide, or fight predators in the way animals can. Rooted to the ground, they evolved a different survival strategy: chemistry. Over hundreds of millions of years, plants developed complex molecules designed to deter microbes, insects, and grazing animals.
