I agree with what Dimitris says. This was a conscious , albeit potentially risky, decision. It was based on a "gut" response.
When Jeff was diagnosed, he was so toxic...high liver enzymes, jaundice, fatigue, brain fog and major constipation (his neuro said it wasn't related to his MS, but I felt it wasn't coincidental- he was in BAD shape). I started him on a liver cleanse and detox program, including anti-virals and anti-oxidants. His symptoms were reduced immediately.
I decided to try the anti-oxidant/anti-inflammatory path, even though,
as you say, this "boosts" the immune system, because he was doing so much better.
I cleared this nutritional program with his neuro and GP (on page one), because I didn't want to do harm, and they said to go ahead. They both felt that we'd know if it wasn't working, because his inflammation and disease process would continue.
He started doing better within a month, the liver enzymes returned to normal, he had regular bowels, his normal color returned, he felt stronger, and a year later, his 2nd MRI has since shown no disease progression and nothing enhancing.
My logic in this pursuit was finding balance in his body, replenishing his vitamin and mineral stores, healing his intestines, and eradicating any viral/bacterial overload. It worked. I suppose it could have backfired. I believe Jeff's first MS flare was related to his gut, liver and diet.
As Dimitris feels in his wife's situation, I think Jeff's first MS flare was set in motion by an over-extended, exhausted and out of balance immune system, turning on itself. We helped return Jeff's immune system to balance, - as reflected in return of motor function, reduction in inflammation, and halting of progression.
hope this makes sense out of the garlic conundrum-
