Electrolytes...Blood pressure is too low---need more sodium. Blood pressure too high less sodium--more potassium. Low sodium levels seem to affect me more than anything because most foods contain plenty of potassium. Although too much sodium can cause potassium imbalances(sodium/potassium pump) Magnesium might be a little hard to come by but I try to rely on diet for magnesium. Not a big fan of hard to digest mineral supps. Can be hard on a weakened GI tract.
Sounds like you might have been doing too much cleansing at once causing too much toxins/inflammation to be released at once. Might be the reason why your rashes got worst. The malic acid might have inflammed your gut too much causing too much mucus production leading to more constipation.
She suggested wormwood? Have you been tested for parasites? Parasite herbs can be harsh on the Gi tract. I wouldnt do parasite cleanse unless I had more confirmation. Global health products did nothing for me.
Curability had a few topical recommendations. Have you tried those?
The consistent rashes definetly sound like some sort of immune/gut imbalances. Candida? Do you have bad reactions to anti-fungals? Does sugar cause head fog/bloating?
Mccombs plan is a good place to start. You might have to modify some of his diet depending on your individual situation.
