I had a patient when I was new in practice, a retired WWII navy medic. He told me of the gonzo treatment he used when medicines were in short supply aboard ship. Works wonders for sore throats and URI’s like cold and flu, and even works with bronchitis and pneumonia:
First, fashion a funnel out of thick oak tag paper. The small end of the funnel will go in the mouth, the large end of the funnel will hover over a pan of boiling secret sauce: a quarter cup of vinegar to a cup of water; use a small pan to boil the mixture.
Use the funnel to breathe the steam rising off the boiling water/vinegar mixture. Be careful not to burn yourself, but try to direct the steam deep against the back of the throat. Repeat throughout the day, each time breathing the steam for a few minutes.
The superheated acidic vapor destroys lesions, bacteria, virus or otherwise. You’ll be amazed at the rapid improvement you get.
