parasite removing supplements

Hey Doc and all !
As I am in Europe (UK) I also am having problems finding a way to get Barefoots dewormer available to me.
I came across a store here that has a parasite killer containing Black walnut, Elecampane, Quassia, Wormwood, Cloves and Cinnamon bark. Would this be an ok alternative to barefoots dewormer or would I be wasting my time?
thanks so much for everybodys support and kind regards!
