Large-leaf Pondweed
Potamogeton amplifolius
Large-leaf pondweed has never been an herbalist's plant, but it has long been a keystone one. Waterfowl hunters and old-time naturalists learned to read a lake by its pondweed beds, since ducks, geese, and marsh birds gather to feed on the seeds and starchy tubers each fall. Anglers came to call it musky weed and bass weed for the same reason bass and muskellunge do, because its dense underwater leaves offer exactly the cover a hunting fish wants. Its value has always been ecological rather than medicinal, a quiet, unglamorous plant that holds a lake together from the bottom up.
In tradition.

The tradition we can stand behind has no household remedy for this plant, so we list none. If that changes as the library grows, this page will grow with it.
Safety.
Large-leaf pondweed has no history of being eaten and is not recommended for eating, partly because wild aquatic plants can carry pollutants or bacteria.
