In the 1960s, British trials documented something impossible: 100 tons per acre, year after year, from a plant that decomposes in 48 hours and requires zero inputs. Then in 2001, it vanished from every garden center in America. This is the story of comfrey, the biological fertilizer factory that threatened a $230 billion industry, and the systematic campaign to erase it from public memory. 🌿 WHAT IS COMFREY? Symphytum officinale, commonly called comfrey or "knitbone," is a perennial plant that was standard in Victorian gardens and medieval medicine. For 2,000 years, Europeans used it for bone healing and wound treatment, but its true power lies underground. 📊 THE LABORATORY PROOF Fresh comfrey leaves deliver 7.09% potassium, 4-5X higher than farmyard manure (which maxes at 1.5%). The plant also contains: - 2-3% nitrogen - 0.5-1% phosphorus - 26% protein when dried - Trace minerals: calcium, magnesium, iron, silicon, boron - Decomposition rate: 48 hours (vs weeks for other green manures) - Yield: 100 tons fresh biomass per acre annually - Production cycle: 20+ years from single planting - Root depth: 6-10 feet (mines subsoil nutrients) ⚠️ THE 2001 FDA CONFUSION July 6, 2001: FDA warned against comfrey supplements for internal use due to pyrrolizidine alkaloids (PAs) causing liver toxicity when swallowed in large amounts. The ban targeted: pills, teas, capsules, products on open wounds NOT banned: External garden use as mulch/fertilizer But headlines said "toxic" without distinction. Garden centers stopped stocking entirely. Public assumed entire plant dangerous. Reality: Soil microbes break down PAs rapidly; no evidence of harm from mulch use. Result: Vanished from mainstream gardening within 5 years despite no ban on garden use. 🌱 HOW TO USE COMFREY - Cut at 2 feet tall (before flowering) - Regrows in 4 weeks - 5 harvests per season = 100 tons/acre/year Uses: - Mulch (breaks down in 48 hours) - Comfrey tea (dilute 10:1, outperforms commercial fertilizers) - Compost activator (heats pile 10-15°F within hours) 📚 SOURCES: - Dioscorides, P.
