The purpose of a honey dipper is to get honey out of a jar without making a sticky mess. The honey sticks in the groves of the dipper, so it won't drip the way it does when you use a spoon.
Hold it over the cup, bowl or whatever sideways (parallel) and let the honey drip into or onto your cup or bowl. You do not use it to stir with, nor do you wash it. Honey has strong antiseptic qualities, which is why they can be kept in the honey, the dipper should not be actually put into the tea.
