"Barngun is cured by blessing, and the outward application of clotted cream, thus : Take three locks of
wool one white, one grey, one black dip them into a basin of clotted cream, and when thoroughly saturated,
take each lock and rub in succession each infected spot on the skin. Hang the wool on sprigs of white thorn against the wind to dry. Repeat this process five, seven, or nine times, as the case may require. While lubricating the sores chant in monotone the following : 

There were three angels come from the west, 

to cure Simon Fluke (or other) of the barngun, 

white barngun, red barngun, black barngun,
aching, sticking, pricking, barngun, 

all sorts of barngun,
barngun-biibee, 

ill will I prove 'e. 

I stick thee
up on thees yer thorn, 

there thou shalt die, 

and never come near'n no more, 

in the name of the Father, Son and Holy Ghost. Amen."

Hewett 1900 

[This charm is very similar to other Devon charms for other ailments in the opening and closing lines, and in the use of colours (take note: there are three colours - 3 is a very frequently used number in folklore). Also note the hypnotically intensifying rhythm.]
