As of yet, there is no scientific evidence to support its use. The MS Society has looked into it some time ago (1998) and found no benefit. http://mssociety.ca/en/research/CAT980602.htm
Additional efforts to investigate its efficacy as an MS treatment have not shown it to be of use. http://www.ncbi.nlm.nih.gov/pubmed/16541972?
