Could lowering high blood pressure be as simple as stimulating your ear?

A small device that gently stimulates nerves through the ear could offer a new way to tackle stubborn high blood pressure.

Although it did not significantly outperform a placebo overall, patients with more severe hypertension showed promising reductions in blood pressure.
