Before modern medicine, pesticides, or pantry shelves full of packaged food, people turned to one reliable source: plants. Our ancestors didn’t have chemical repellents, antibiotics, or multivitamins. Instead, they relied on nature’s pharmacy, using specific herbs, roots, and greens not only to treat illness but also to keep pests at bay and sustain their families through hard times. For them, plants weren’t ornamental—they were essential for survival.
These weren’t exotic or rare botanicals either. Many of the plants they trusted grew wild in forests, fields, and homestead gardens across early America. Some repelled mosquitoes and flies, others were brewed into healing teas or used in poultices, and quite a few were just nutrient-dense foods that got people through long winters or lean harvests. One plant could serve multiple purposes—feeding the body, protecting the skin, and soothing a cough—all at once.
Today, most of these powerful plants have been forgotten or replaced by store-bought alternatives. But as interest in natural remedies, sustainable living, and ancestral wisdom grows, it’s time to rediscover what they knew so well. Here are 15 remarkable plants our ancestors relied on to fight bugs, illness, and hunger—and why they’re still worth growing and using today.
