Despite its high content of proteins, minerals and vitamins, it is shunned by many herbivores \u2013 not because of a lack of nutrients, but due to its highly effective defence strategy. For humans, this manifests as a brief stinging sensation on the skin; biologically, however, it is a finely tuned interplay of mechanical injury and chemical signalling. The stinging nettle thus provides a clear model for investigating plant defence mechanisms."}
