In the West, it is known primarily as an invasive nightmare — a plant that destroys foundations, devalues property, and resists eradication. In East Asia, the same plant has been a first-line medicinal herb for over two thousand years. In contemporary Western herbalism, it has become central to protocols for Lyme disease and tick-borne infections. This text examines how one plant sustains such divergent reputations, and what its pharmacology reveals about the relationship between traditional observation and modern molecular science.</p>
