I was looking at the information on this since I know that research on other issues can also be helpful in understanding MS.
It seems this was a drug developed in the 1800s and from what I have read it seems to be a different way of looking at things that apply to axon damage in the nervous system.

I think it may offer a new glimmer of hope.
If you google Rember you will find all kinds of opinions on it.
