I am about to start the 30 day trial period of drinking wu-
long tea.

The what? Oolong is just tea. If you like it, drink it. If not, don't.

I am concerned that it may block medications
(such as birth control and allergy) I am on. Will this
really happen?

Does the stuff you get in ordinary teabags block your medications?
