Superhot Naga Chili Peppers
The chili pepper does not want to be your friend. It wants to hurt you so badly you turn it loose. Plants cannot bare teeth or run for the hills; they must protect themselves passively. Some are horribly bitter. Others, less forgiving, are poisonous. Capsaicin, the primary active ingredient in hot peppers, falls into the category of irritant, but that’s an insult to its power. (Chemical irritation, or chemical feel, is the third of the chemical senses, along with smell and taste.) Capsaicin in the eyes or airways is disabling to the extent that it is used as a nonlethal weapon—pepper spray. Bhut Jolokia grenades were developed several years ago by India’s Defence Research and Development Organization and used on protesters in Kashmir. (The grenades were shelved because the chili powder is prone to fungal rot.) Both the eyes and the airways are extremely sensitive, far more so than the skin or tongue. This is normally—outside of protests and riots—a good thing, because seeing and breathing are crucial to survival; the sensitivity of these organs and tissues motivates their owner to keep them safe.
Less immediate but no less excruciating are the effects on the digestive tract. As I’m about to see.
