Theives Blend is a very good antibiotic. It was used by theieves in France during a period of plague. They robbed a lot of the dieing and dead victims of the plague without becoming unwell themselves.
Its completely herbal, but I do not know of any UK shops which sell it. It can be bought from the USA, but this is not a solution for those who want to avoid mail order.
