Such assumption was put forward by the American scientists from the Massachusetts hospital. They have suggested to use as local anaesthesia (for example, in stomatology) Chile hot pepper as the substance капсаицин, giving to it a sharpness, possesses soothing property.
Kapsaitsin is interesting to that influences only the nervous cages which are responsible for feeling of pain, without paralysing thus the neurons which are responsible for movement of muscles or for transfer of other feelings.
Now anaesthesia by means of chilli pepper is successfully carried out on laboratory rodents. And in some years researchers plan to start to carry out tests in public.
