You could also eat a clove(section) or two of raw garlic each day after a large meal. olive leaf extract, B vitamin supplements, and plenty of vitamin c might help. Avoid all fragrances and scented products. MCS may also be caused or worsened by intestinal parasites. Doing some parasite cleanses may also help. Amalgam removal may initially make the MCS worse, but several months later it might subside quite a bit.
