I still strongly believe that there has to be a way to ingest something that will regenerate our hearing. I've said this many times that when they were testing ly411575 on rats the initially administered it orally and it was successful in the goal of restoring hearing. That was a pure gamma secretase inhibitor though and anything else from a plant source will probably not be as potent. These little cell signalling pathways certainly won't only respond to man made lab chemicals. The question is how to get enough to permeate the blood labyrinth barrier to affect the progenitor cells and or the neurons and their synapses.
