tutsan

Tutsan, tut′san, n. a species of St John's wort, once regarded as a panacea—also called Park-leaves.

A closely related plant is Hypericum androsæmum, known as Tutsan, said to mean toute saine, as curing all hurts.

Fortunately the tutsan is not "retiring from business" in Nature's garden.

Tutsan (Hypericum androsmum) was used to stop bleeding, because the juice of its ripe capsule is of a claret colour.
