Suggestions for how to approach persistent vomiting caused by high fevers from viruses in a child. I think need something that can be applied externally that calms the spasm of the stomach. The stomach seems to get turned over and anything, even a small amount of water triggers it. I have tried infused St. John’s Wort, and poultice with Cramp Bark. And I’ve either tried teas or oils for every digestive herb I can think of that with some exceptions for contraindications.
