This lady customer, J, used to come to my shop and formerly she got her treatment for her skin problem from my former sifu. Since he had already left my company, I introduced her to my new master, L.
L has recommended herbal package for her to boil and drink the soup. This package consisted of a frog's skeleton with other herbal stuff. She was reluctant initially but I managed to put her fear at bay.
After L had packed 3 packets, he explained to J how to consume them. She were to take it for three consecutive days.
She were told to come back after three days...
