I agree, MS is an auto immune problem where the immune system has gone troppo and attacks its own body. I googled and could find zero research on this with EO. I did find an EO user who contends that candida is a trigger irritating the immune response so it attacks the body. I have zero knowledge or opinion. So based on her idea, suggest a gentle blend including a calming oil, a candida deterrent and heliochrysum. I know if I was desperate I would make up something this.
