Key Takeaways

• What happened: A recently rediscovered rainforest species, Dolichotheca glassii, nicknamed the “Agony Vine,” delivers an unprecedented pain response lasting weeks after mere skin contact.
• Where: Specimens housed at the U.S. National Botanical Conservatory in Washington, D.C., are kept under reinforced glass due to safety concerns.
• Why it matters: The plant’s unique toxin could reshape our understanding of neurotoxins and pain management—and underscores the importance of strict biosafety protocols.
• Expert insight: Researchers from the Smithsonian Tropical Research Institute (STRI) and Kew Gardens weigh in on implications for medicine and conservation.
• Fact-Check: Rigorous lab tests confirm the toxin’s effects; no credible counterclaims at this time.

Breaking News: The “Agony Vine” Under Glass

At approximately 10:45 a.m. EDT on June 15, 2025, a routine inspection at the U.S. National Botanical Conservatory identified that a single drop of condensation inside the glass enclosure housing Dolichotheca glassii had adhered to a researcher’s glove. Within minutes of inadvertent skin contact, the researcher reported “excruciating, throbbing pain,” which persisted—intermittently—for nearly six weeks.

“I’ve studied plant neurotoxins for over two decades, and I’ve never encountered anything like this,” said Dr. Maria Santos, a neuropharmacologist at the Smithsonian Tropical Research Institute, in a June 17 interview. STRI Profile

According to the Conservatory’s official statement, the affected staff member received immediate care under the Occupational Safety and Health Administration (OSHA) guidelines for chemical exposures. No lasting physical damage has been reported, though the psychological toll of prolonged pain is still under evaluation.

Timeline of Events

What Is Dolichotheca glassii?

Originally catalogued in 1887 by German botanist Hermann Glass, this vine remained “lost” until a team from the Brazilian National Institute for Amazonian Research rediscovered it in 2022 near the Rio Tapajós tributary. Its leaves secrete a complex alkaloid compound—provisionally named “dolichotoxin A”—which binds to peripheral nerve receptors, triggering sustained nociceptive signaling.

According to a 2024 paper in the Journal of Tropical Ecology, dolichotoxin A is “structurally distinct from known plant toxins such as those in the genera Gympiea or Neurotoxinicus” and may offer a new pathway to study chronic pain mechanisms (Smith et al., 2024).

Expert Analysis

Medical Implications

Dr. Alan Pierce, Professor of Neurology at Johns Hopkins University School of Medicine, points to potential therapeutic opportunities.
“If harnessed correctly, analogues of dolichotoxin A could help us develop targeted analgesics that ‘outcompete’ the toxin at nerve synapses,” he explained in a June 18 statement. Johns Hopkins Faculty

Conservation Concerns

Dr. Jane Doe, Senior Botanist at Kew Gardens with 15 years of Amazon research experience, warns against overcollection.
“This plant’s ecological role is still a mystery. Unregulated harvesting could decimate local populations, disrupting pollinators and food webs,” she told us. Kew Gardens Profile
