But Thyagarajan says his team has come up with a spice-proof way to get capsaicin into the body. A doctor would inject the drug directly into areas with a lot of fatty tissue. Magnets would coat each particle. The doctor would use a magnetic belt or wand to hold the particles in place. This should keep the capsaicin from circulating through the body. Thyagarajan believes that this would help prevent side effects.
