One might imagine that a growing interest in alternative medicine is all good. However, when combined with the relentless destruction of native habitats, the increasing use of herbal remedies has "led to the depletion of native stands of plants such as ginseng (Panax quinquefolium), goldenseal (Hydrastis canadensis) and purple coneflower (Echinacea angustifolia)." So says Nancy Scarzello of United Plant Savers. As a result, these three plants are on the endangered list in several states.
Not incidentally, echinacea is currently the top selling herbal supplement in America. Garden Guide explains why: "More than just another pretty face among the wildflowers, Echinacea Purpurea (and other varieties of the plant) has long been used by Native Americans and Europeans as a booster of the immune system, potent preventer of colds and flu, and fighter of infections such as bronchitis, all in one." It's great that so many people are getting hip to herbs like echinacea but thereby more urgent than ever to ensure the plant's long-term sustainability. The USDA's plant profile of echinacea will keep you up-to-date on which varieties are threatened so you know how to source it responsibly.
Ways to help protect threatened medicinal herbs:
The folks at Rodale offer three simple steps:
1. Set up a sanctuary. Join United Plant Saver's Botanical Sanctuary Network and turn your backyard garden into a safe haven for medicinal plants. If needed, United Plant Savers will dispatch an expert to help you identify any existing plants already on your property.
2. Grow plants just for fun. Less involved than starting an actual sanctuary, this avenue can still help ensure the survival of a particular species.
3. Do a background check. As you might already do with other purchases, learn more about the companies that sell the herbal supplements you consume. It should come as no surprise that some manufacturers are more diligent than others when it comes to harvesting plants.
