Lisa, I am also allergic to most everything. What I had to do is:
Start by taking very small amount of everything separately....1/2 - 1 teaspoon of olive oil. Wait to see if you have reaction to that, then maybe even wait until next day take 1 tsp grapefruit juice. Start the same way with Epsom Salts . If you don't have a reaction to that amount then up the dosage until you reach the correct flush dose. I started with mini flushes, 1 TBSP. olive oil with 1/2 cup grapefruit juice to see how I tolerated the oil. Go slowly and build up to the 1/2 cup oil. I learned the hard way to start small. The ES is what I have the worst allergic reaction to I actually have had seizures from it. I only can tolerate at most on a good day 1 tsp. ES. Let us know how you do.
