but i think the ink that was used to write the Tiger character has to be from some herbs. Maybe it is the herbs that is helps. Maybe the doctor or master who invented this was just trying to be creative during treatment and somehow people mis-interpret ...
I'm quite doubtful on the ink, as myself personally have been asked by my parents to write the word onto ppl's cheek occasionally coz im the only tiger in our family and relative members. I was alwiz wondering what can a word 虎 help to cure it.
Possibly is like what flexon said, pyschological helps in the self healing process. Snake canot leh, later eat the pig d poison the owner how leh? hahaha
