Species At-Risk List

For the benefit of the plant communities, wild animals, harvesters, farmers, consumers, manufacturers, retailers, and practitioners, we offer this list of wild medicinals of North America to bring awareness to these sensitive species. Our intent is to assure the increasing abundance of medicinal plants and fungi which are presently in decline due to expanding popularity and shrinking habitat and range.



“In Review”

  • Arnica – Arnica spp.
  • Chaga – Inonotus obliquus
  • Eyebright – Euphrasia spp.
  • Ghost Pipe – Monotropa uniflora
  • Lobelia – Lobelia inflata
  • Skunk Cabbage – Symplocarpus foetidus
  • Solomon’s Seal – Polygonatum biflorum
  • Wild Cherry – Prunus serotina

Analog List for At-Risk and To-Watch Herbs

Compiled by Jane Bothwell, March 2000, revised 2006

After introduction to the United Plant Savers list of “At-Risk” plants, students always ask, “Well, what can we use in its place?”  Often times the choice is simple: choose a cultivated species rather than one harvested from the wild.  When cultivated species are not available, then it is best to find a plant analog.  An analog is something having an analogy or similarity to something else.  For our purposes, this indicates parallels in function or end results between two or more medicinal herbs.

Following is an alphabetical list of most of the United Plant Savers “At-Risk” and “To-Watch” lists, accompanied by suggested analogs.  This list is compiled by the author and does not necessarily reflect the opinions of UpS.

Our intent is to assure the increasing abundance of the medicinal plants which are currently in decline due to expanding popularity and shrinking habitat and range. UpS is not asking for a moratorium on the use of these herbs. Rather, we are initiating programs designed to preserve these important wild medicinal plants.
