Yeah, I don't think I can take the 1/2 cup of Extra-Virgin Olive-Oil ( Hulda Clark 's recipe). It burns my throat. I'm not sure if mixing it with citrus would lessen the burn. Plain olive oil (Dr. Kelley) on the hand is probably okay. It seems like it doesn't really matter that much what type of oil you use as long as it is pure. Some recipe calls for whipped cream instead of oil. (Uny did cream and berries with 2 of her most successful flushes?) Although, I'm curious at which type of cream she used. Many ppl have trouble with diary products. So, I would probably stay away from that....
