This “Forever Plant” Heals Your Gut — And the USDA Wants It Gone

What if the invasive vine you see smothering trees in your backyard is actually a superfood that could have saved the world from famine? Meet the Cinnamon Vine, also known as Chinese Yam (Nagaimo, Dioscorea polystachya)—a plant that the U.S. government labels as a tier-one invasive species, yet in East Asia, it is a multi-billion dollar crop celebrated for its nutrition and healing properties.
In this video, we uncover the hidden story behind this misunderstood plant. Brought to America in the 1800s during the potato famine, it was once hailed as the “esculent of the future”—immune to blight, highly nutritious, and storable for years. William Robert Prince, a prominent American horticulturist, promoted it as the perfect solution to famine, drawing on centuries of knowledge from Chinese medicine, where it is revered as a tonic for the gut, lungs, and overall vitality.
So why isn’t it on our plates today? The answer lies in its unique growth pattern. Unlike potatoes, which grow horizontally near the surface, the cinnamon vine grows vertically, sending tubers 3–5 feet deep. 19th-century mechanized harvesters couldn’t reach these deep roots, and with potatoes becoming easier to farm, this miraculous crop was abandoned. Today, it survives in the wild—labeled a weed—but it remains a nutritional powerhouse:
Rich in potassium, resistant starch, and digestive enzymes (you can even eat it raw!)
Contains allantoin, a natural compound that supports tissue repair and gut health
Mucilage in the root soothes the stomach and intestines, unlike starchy potatoes
We also reveal the modern “gutter method” for harvesting this vine without backbreaking digging. With this simple technique, gardeners and permaculture enthusiasts can grow straight, manageable tubers—even in small backyard plots.
⚠️ Safety Tips: Peel carefully to avoid calcium oxalate crystals, and know the difference between edible Dioscorea polystachya and toxic air potato (Dioscorea bulbifera).
This is more than a story about a “weed.” It’s a chance to rethink our relationship with food, revive forgotten crops, and explore a superfood growing in plain sight.
