Herbalism and Climate Change: Protecting Endangered Medicinal Plants

As herbalism continues to grow in popularity, more people are turning to nature for healing and wellness. But while the benefits of herbs are widely celebrated, there’s a pressing issue that isn’t talked about nearly enough: the impact of climate change on medicinal plants. Herbalism and environmental stewardship are inextricably linked—especially now, as rising temperatures, shifting weather patterns, and human overharvesting threaten the very plants we rely on for healing.

Climate Change and Plant Vulnerability

Climate change affects plant life in complex and often unpredictable ways. Shifts in temperature and precipitation patterns can disrupt the delicate ecosystems that many medicinal herbs depend on. Some plants are highly sensitive to small changes in their growing conditions. For example, Goldenseal and American Ginseng, two widely used North American herbs, are already considered at risk due to habitat loss and overharvesting. Climate stress only adds to their vulnerability, potentially pushing them toward extinction.

Additionally, climate change influences the timing of plant growth cycles, known as phenology. A warming climate might cause plants to bloom earlier, disrupting relationships with pollinators or altering the concentration of active medicinal compounds. This not only impacts the plants themselves, but also diminishes their effectiveness and sustainability as herbal remedies.

The Role of Ethical Herbalism

As herbalists, foragers, and plant lovers, we have a responsibility to practice our craft in a way that honors and protects the earth. Ethical herbalism begins with awareness: understanding where our herbs come from, how they’re grown or harvested, and what impact our choices have on plant populations.

One step is to avoid wild-harvesting endangered herbs altogether. Instead, seek out cultivated sources or plant your own. Look for suppliers that are certified organic or work with conservation organizations. Learn about the United Plant Savers “At-Risk” and “To-Watch” lists, which provide essential guidance on which plants need protection.

Supporting Regenerative Practices

We can also be part of the solution by supporting regenerative agriculture and small-scale herb farms that focus on biodiversity, soil health, and sustainable harvesting. These practices help build resilience in plant populations, even in the face of climate change.

If you grow your own herbs, consider cultivating native plants and pollinator-friendly gardens. Not only does this support biodiversity, but it also reduces dependence on wild-harvested sources. And remember—sometimes the most powerful medicine is already growing in your backyard and usually the medicine you need the most!

Advocacy and Education

Lastly, we must raise our voices. Whether it’s through writing, teaching, or simply having conversations, herbalists can play a vital role in connecting others to the natural world and advocating for its protection. Climate change is not just an environmental issue—it’s a health issue, a cultural issue, and a call to reconnect with the earth in a more conscious way.

Conclusion

Herbalism has always been about more than just plants—it’s about relationships with nature, our plant allies, Mother Earth, the land and our ancestors, and our own natural wisdom within capable of amazing healing. As the climate shifts, we must deepen our commitment to those relationships by choosing sustainable practices and protecting the very ecosystems that give us life. The future of herbal medicine, the planet we call home, and us depend on it.
