There is a plant growing in gardens and along hiking trails that looks exactly like comfrey when the flowers are gone. It grows in the same damp soil. The leaves form the same soft rosette. People harvest it thinking they are making herbal tea. Within hours, their heart begins to fail. Within days, some of them are dead. The mistake [music] has killed experienced foragers and herbalists across three continents. The plant is fox glove digitalis perpia. Every part contains cardiac glycosides that stop the human heart. There is no margin for error. You are watching forgotten soil. We reveal the poisonous plants hiding in plain sight disguised as food. Every episode [music] we expose one more deadly mimic. If you want to stay safe, subscribe now. This is today's warning. Fox glove is not rare. It grows wild across Europe, North America, and Asia. You have seen it in [music] public parks and along mountain trails. It thrives in the same damp woodland edges where people harvest comfrey for medicinal tea and borage for salads and summer drinks year after year. The confusion happens in spring before the [music] distinctive purple flowers appear when fox glove exists only as a basil rosette of soft gray green leaves on the ground. From a distance it looks harmless. Up close it looks edible. The leaves are large and oval, covered in fine hairs arranged in a circular pattern. This is exactly how comfrey appears in early growth. This is exactly when foragers are harvesting fresh spring greens for their kitchens and their remedies. Garden centers have sold fox glove labeled as borage. Experienced herbalists have brewed it into tea. Families have baked it into pies they served for dinner. The plant does not warn you. It does not taste strongly bitter. It does not burn your mouth. It allows you to consume it completely. Then the cardiac glycosides enter your bloodstream. Digtoxin, gtoxin, digital compounds that were used as heart medicine in controlled medical doses for two centuries. In uncontrolled doses from the actual plant, these same compounds attack the sodium potassium pump in every cell of your heart muscle tissue [music] systematically. Two to three dried leaves can kill an adult. Five fresh leaves have caused documented fatalities. A tea made from a handful is extreme danger. The question people ask after they realize the mistake is always the same. How did I not know? How does this keep happening to people? Taiwan 2010. Nine people consumed tea they prepared from leaves they believed were comfrey. They bought the dried herb from a trusted local supplier. Within hours, all nine presented to emergency departments with nausea and vomiting. Three developed severe cardiotoxicity. Their hearts began producing dangerous irregular rhythms that required immediate pacing. Blood tests revealed serum dejoxin concentrations between 4.4 and 139.5 [music] nanog per milliliter. The therapeutic range for the heart medication dejoxin is 0.5 to2. Doctors administered 40 to 80 milligrams of dejoxin specific antibbody fragments. The antidote designed to bind and neutralize cardiac glycoides circulating in human blood and tissue. The antidote had no effect. Plant-based digtoxin has 30 to 100 times lower affinity for the antibodies compared to pharmaceutical deoxxin preparations used clinically. All nine patients survived through temporary cardiac pacing and intensive supportive care alone. They were fortunate. The next case was not as fortunate at all. Taiwan, 2017. A 55-year-old [music] woman drank tea made from fox glove leaves she thought were comfrey. 8 hours later, she arrived at the emergency department. She was weak, nauseated, vomiting. Her heart [music] rate had dropped to 54 beats per minute. Her potassium level was 7.6 mill equivalents per liter. Normal potassium is 3.5 to 5. [music] Levels above seven indicate the sodium potassium cellular pumps throughout the body [music] are failing under toxic cardiac glycoside blockade systematically. The electroc cardiogram showed first-degree heart block with premature atrial contractions. [music] 3 hours after arrival she developed polymorphic ventricular tacicardia. Her heart was beating chaotically and ineffectively. Her serum dejoxin level returned at 151.2 [music] nanog per milliliter. Anything above 10 is considered potentially lethal. She was 75 times beyond safe [music] levels. While waiting for the antidote infusion to begin, her heart went into ventricular fibrillation. Resuscitation started. They established venoarterial extracurrial membrane oxygenation to mechanically circulate her blood. Eight vials of dejoxin specific antibodies were administered over 16 hours. She temporarily regained consciousness. Then she developed lower limb eskemia from the life support circulation. Multiple organ failure followed. She died on hospital day 7 despite every available advanced cardiac life support intervention including mechanical circulation and maximum antidote dosing repeatedly. Italy 2019. A 55-year-old woman bought a plant from a garden nursery. The label on the pot said borage. She used five leaves in a homemade pie. 4 hours after eating, she felt weak and nauseated. The emergency department found her dejoxin level at 10.4 micrograms per liter. Above 10 is potentially lethal concentration. She was admitted to cardiac intensive care. 2 days later, telemetry recorded advanced atrial ventricular block. Her heart's electrical system was failing under the glycoside assault on conduction. The plant she brought to the hospital for identification was fox glove. The garden nursery had mislabeled it. She survived without antidote through 11 days of monitoring alone. Ireland [music] 2021. A 22-year-old man blended two large fox glove leaves from his garden with apple, cucumber, and lettuce to make a healthy herbal juice. 2 hours later, he became ill. The next day, he presented with persistent vomiting, drowsiness, blurred vision, and numbness spreading across his lips and face. His heart rate was 40 beats per minute. Serial electroc cardiograms showed progression from sinus brada cardia to firstderee block to secondderee block to complete heart block. His kidneys were failing. His potassium was 5.3 and rising. He received activated charcoal atropene and dejoxin specific antibodies. He spent 10 days in hospital. He survived but only because his parents identified the plant quickly and he [music] reached the coronary care unit before the ventricular arrhythmias became refractory to treatment. So how does this happen? Let me show you the deception. Let me show you what these people saw when they harvested the wrong plant. Comfrey grows in damp meadows and woodland edges. It has large oval leaves arranged in basil rosettes during early growth. Foragers seek it for traditional bone healing remedies. Fox glove grows in the same places, same season, same size during the critical first year when it produces only leaves and no identifying flowers whatsoever. [music] But the difference is there. You can see it, you can feel it, you can verify it without tasting anything. Seven distinct features separate life from death. Look at the leaf edge. Run your gloved finger along the margin. Comfrey has completely smooth, uninterrupted edges. Fox glove has fine serrations like small rounded teeth touch the leaf surface. Comfrey has stiff, bristly hairs that feel rough like sandpaper. Fox glove has soft, velvety hairs that feel like wool or velvet fabric. Turn the leaf over. Comfrey underside is green with visible veins. Fox glove underside is gray white or silvery from dense woolly hair covering the entire surface. Examine the leaf stem. Comfrey pedoles have sparse bristly hairs you can see and feel individually. Fox glove pedals are covered in dense soft fuzzy hairs. Crush a small piece with gloved hands and smell. Borage smells like cucumber. Comfrey has a mild herbal vegetable [music] scent. Fox glove has little to no distinctive odor. Look at the growth habit. Fox glove forms a tight compact rosette springing directly from the root. Comfrey forms a more robust spreading clump as a perennial. Check the vein pattern. Both have prominent veins, but comry veins are notably more pronounced. These are the features that separate the living from the dead foragers. The worst confusion period is spring and early summer before fox glove produces its secondyear flowering stem. [music] That is when both plants look most similar from any distance. That is when people make the assumption. They see soft hairy leaves in a damp area. They remember comfrey grows there. They harvest without verifying every feature. The toxin is digtoxin, a cardiac glycoside that inhibits the sodium potassium ATPAS pump embedded in the membrane of every heart muscle cell in your body. You cannot cook it out. Heat does not break down cardiac glycosides even at boiling temperatures for extended periods of time and repeated processing. You cannot induce vomiting safely. The toxins absorb through stomach lining within 1 to two hours and emmesis can cause additional cardiac complications and aspiration. You cannot wait for symptoms. Digtoxin [music] has a halflife of 7 days and liver damage begins before you feel anything wrong with your body at all. You cannot trust field identification apps. Artificial intelligence recognition requires multiple cross checks and expert verification before consuming any wild plant material ever under any circumstances. You cannot rely on animals. [music] Deer and livestock can consume small amounts. Humans cannot. The therapeutic dose for medical use is dangerously close to lethal. Within 2 to 8 hours of consuming fox glove leaves, the first symptoms appear. Nausea, [music] vomiting that can persist for more than 24 hours straight without relief, abdominal pain and cramping, [music] diarrhea, weakness spreading through your limbs, dizziness when you try to stand, loss of appetite, headache that will not respond to medication. Within 3 to 17 hours, the cardiac manifestations begin. Your heart rate drops. 40 beats per minute, 35. First degree atrial ventricular block appears on the monitor. The electrical signals between the upper and lower chambers of your heart begin to fail. Second degree block develops. Then complete heart block where coordination is lost entirely. Some patients experience premature ventricular contractions. Others develop paroxismal atrial teacardia with block. The pathognemonic sign is birectional ventricular tacocardia seen almost exclusively in digitalis [music] toxicity. Your vision changes. Colors shift toward yellow green. Halos appear around lights. This is zanthopsia. The same visual disturbance that may have affected Vincent Van Go. Confusion sets in. Lethargy. Delirium. In severe cases, hallucinations. Your lips go numb. Trembling starts. In the most severe poisoning, seizures can occur before death. Your potassium level rises [music] 5.5 6 7 7.6 documented in fatal cases. Hyperc calmia above 7 mill equivalents per liter is a predictor of mortality. The cruelty is the progression. Early symptoms seem manageable. Just gastric [music] upset, just fatigue. By the time the cardiac arhythmias appear, the glycosides are already systemic. Treatment must start within hours. Activated charcoal if you reach the hospital within 4 hours. Multid-dosese charcoal for 24 hours to interrupt interrohypatic recirculation completely. Atropene for the brady cardia temporary cardiac pacing for heart block. Dejoxin specific antibbody fragments if you can get them. 400 to 500 mg initially, but the antibodies bind [music] digtoxin poorly, 30 to 100 times less effectively than pharmaceutical dioxin. Patients may show only transient response or no response at all. Some cases require veno arterial extra membrane oxygenation, a machine that circulates your blood outside your body while your heart tries to recover from the glycoside assault. [music] Even with every intervention, some patients die. Lower limb eskemia, multiple organ failure, refractory ventricular fibrillation. Asylly, the heart simply stops despite maximum medical support available. The digtoxin remains in your system for days. Halflife of 7 days compared to 1.5 days for pharmaceutical deoxin. You need intensive monitoring for a week minimum. If you survive the acute phase, you typically recover fully. But the 10 days in cardiac intensive care, the temporary pacing, the antibbody infusions, the fear every year [music] more cases appear. The foraging trend intensifies without corresponding education. Social media shares plant identification posts with dangerous errors. Influencers without botanical training recommend wild harvesting. Garden centers mislabel plants. Apps misidentify species. People assume natural means safe. They trust their memory. They trust a single feature. They harvest based on location alone. Children pick the beautiful bell-shaped purple flowers in summer, not knowing every part is deadly. Adults harvest the gray green rosettes in spring, not checking every identifying feature. The plant evolved cardiac glycosides as defense against herbivores. It did not evolve to warn humans. It did not evolve with bright warning colors or intensely bitter taste. Not stupidity. Deception. Experienced herbalists have died. Trained foragers have been hospitalized. A woman consumed a plant that a commercial nursery sold labeled as edible borage incorrectly. [music] That mistake is preventable. Here is how you never make it. Here is the protocol that keeps you alive when you want to harvest wild plants. Where Fox Glove grows matters. damp woodland edges, hiking trails in the Pacific Northwest, public parks with ornamental plantings, roadsides and field boundaries across tempered zones globally [music] when identification is critical matters more. Spring before the flowers appear, early summer when only the rosette exists. Anytime you see soft, hairy leaves near water, [music] never trust one feature alone. Check the leaf edge for serrations. Feel the texture soft versus bristly. Turn the leaf over for gray under surface, not green. Examine the pedial hairs, dense and fuzzy versus [music] sparse and stiff. Crush and smell for absence of cucumber scent. Look at growth habit rosette versus spreading. If you cannot confirm all seven distinguishing features with absolute certainty, assume the plant is poisonous. Do not harvest. Do not consume. Do not risk your life. If exposure occurs, call poison control immediately. United States 1 8002221222. Do not wait for symptoms. Do not induce vomiting. Go to emergency room. Tell them fox glove. Tell them cardiac glycosides. Tell them the exact time and amount consumed. Bring the plant specimen in a sealed bag for verification. They will monitor your heart continuously. They will check your potassium every few hours. They will give activated charcoal and atropene and antibodies if indicated by severity. Every person who learns these seven features can teach someone else. Every conversation is one more forager who checks all features before harvesting any wild plant. The soft gray leaves they trusted the familiar location they [music] remembered. The healthy herbal juice they blended. The comfry tea they thought they were making. The borage pie labeled safe by the garden center that sold them poison. The herbalist who died had 40 years of experience with medicinal plants. The woman who died bought the plant from a commercial nursery. The man who survived spent 10 days in cardiac intensive care after two leaves in a smoothie. Now you know what they missed. Fox glove is still here. Still growing along hiking trails and in public parks where children play and foragers harvest wild edibles carelessly. Still disguised as comfrey and spring. Still waiting for the next person who assumes instead of verifies all seven features with gloved hands. Soft leaves. Fatal heart failure. Seven features separate [music] them.
