IF YOU have ever absent-mindedly rubbed your eyes or nose after chopping up chilli peppers, you’ll have some idea of the suffering of one group of scientists in the name of medical research. A team at the Institute of Neurology in London have been injecting chilli juice into each others’ foreheads. Lab technician Paul Hammond, who got roped into the experiment, says it felt like acid was burning into his skin. “It was one of the most excruciating pains you can imagine,” he recalls.
The researchers weren’t sadomasochists, as far as we know. Their actions were part of a much larger research effort that has been shedding light on migraine. For although in the past few decades we have learned a great deal about the condition, we still have no idea of its root cause. And while we have drugs that help some patients, some of the time, understanding the underlying defect is the best way to boost our chances of discovering a sure-fire cure.
