I can relate to the Master Cleanse. I didn't last as long as you did! But, I keep telling myself----someday, I'm gonna do it!!
As far as the rash, I can't help but feel like it some type of toxin, but I'm not sure. I'm just curious about the type of oil you are using. I am not familiar with Wormwood oil and, of course, I have heard of frankensense oil from the Bible, but I am not familiar with that, either. Could you tell me why you are using them on your feet? (softening?)
