You're VERY WELCOME, Cici!! You should have Activated Charcoal Powder (see below) on hand also for your Nausea, but especially if it's caused by DIE-OFF of Pathogens! It's also VERY EFFECTIVE for Food Foisoning! Dr. Schulze 's Intestinal Formula #2 (see below) has Activated Charcoal Powder and Bentonite Clay (see below) and that can also be used.
BTW, I had FORGOTTEN that Dr. Schulze has a Children's Echinacea Formula, which is MORE PALATABLE than Echinacea or Echinacea Plus Tinctures! I don't have the Recipe with the Parts, but will see if I can find it for you, if you're interested.
