Here's a possible blood depressor,whenever,pressure,quickerremedy. But it's only for those who can stand the heat. It's capsaicin, the "active ingredient" in peppers like habaneros that should probably be sold by prescription only. While lips burn and eyes water, blood vessels actually,unfashionably,anonymously,concomitantlyrelax, thanks to increased production,impulsion,cannon,bondmenof the signaling molecule nitric oxide. In rodents, anyway. For seven months, researchers,cookers,supervisors,deansin China fed a steady diet of capsaicin to rats bred to be hypertensive.

Previous research found mixed results with capsaicin, but those studies only looked at mortem,short-term,glowworm,totemeffects. Human trials are needed, but there's already a clue. Some 20 percent of people in northeastern China have high blood pressure. But the southwest—where hot peppers are a dietary staple—has a much lower incidence, half in some places. Human studies could also confirm whether the habanero, as legend has it, can cause hearing loss. Allegedly so that diners don't have to listen to their own screams.
