A controlled animal study published in Daru: Journal of Faculty and Pharmacy, Tehran University of Medical Sciences found that topical treatment with 1% purified (i.e. >98%) CBD topical cream may help to reduce damage caused by a disease that results in brain inflammation. This holds relevance for humans with autoimmune diseases that lead to demyelination (damage to the fatty covering around neurons that helps them to transmit signals faster) like multiple sclerosis.
Topical CBD vs. Multiple Sclerosis Experiment
Using healthy mice and mice with experimental autoimmune encephalomyelitis [(EAE)- encephalo= brain, myel= myelin= fatty nerve covering, itis= inflammation] as models for humans with multiple sclerosis, researchers applied either 1% purified CBD cream, inactive cream, or no cream to the skin of the healthy mice, and to the skin of diseased mice once symptoms of EAE began to appear. The mice were observed daily, and 28 days after EAE had been induced, spinal cord and spleen cell samples were taken.
