A cure for Diphtheria was written in the journal of John O. Wieland about 1917 as follows:
"It will cure in from 6 hours to 2 days. I have used this cure for over fifty years and never knew of a failure or heard of one for diphtheria. It will not cure tonsillitis or quinsy. There is no need of a quarantine when this is used.
Mix Tincture of Gym Myrrh with Cayenne Pepper until almost thick, 100 worth will cure several persons. Shake bottle before using, then for adults take a teaspoonful throw the head back, pour in throat, gargle a little while then spit out.
For a child make a swab and thoroughly swab the throat. If some is swallowed it does not harm. For cholera morbus or running off of bowels, fill two or three capsules with cure, it will give relief in a few minutes.
They say for blood poison or gangrene there is nothing to equal it.
Get 10(~ worth and keep it in the house so you will have it when needed. C. O. Brown for diphtheria."
