In human physiology, silver plays an important role. It is literally an essential trace element for the peripheral nervous system. Scientific peer-reviewed publications have identified that there are receptor sites for silver in myelin neural tissue. Receptor sites do not occur by accident; if you have them, they are there for a very specific reason. Scientists and doctors are speculating that this may be due to silver?s unique properties – including its electrical conductivity, inflammation modulation and regenerative properties.
