Why the 'Frog Poison' Version Emerged

The issue of Navalny's alleged poisoning resurfaced in the media following an official joint statement by five European countries — the United Kingdom, France, Germany, Sweden, and the Netherlands.

According to the statement, laboratory tests conducted on biological samples reportedly taken abroad by Navalny's family detected epibatidine, a potent neurotoxin naturally found only in the skin of certain Ecuadorian poison dart frogs. The toxin can cause muscle paralysis, convulsions, and respiratory failure, symptoms which Western forensic specialists claim correspond to descriptions of Navalny's condition before his death.

The choice of such a rare substance has been interpreted as an attempt to obscure traces due to its exotic origin and limited availability. At the same time, critics question why such an unusual toxin would be used when more widely studied substances exist.

Forensic Questions and Chemical Stability

Epibatidine is an organic compound. Like many natural alkaloids, it degrades under the influence of enzymes in blood and tissues, as well as exposure to temperature and light. Critics argue that if biological materials were stored for a year under non-specialized conditions, identifiable traces of the toxin would likely have broken down.

While certain toxins can remain detectable in hair samples for extended periods, such materials typically require immediate freezing at extremely low temperatures or treatment with specialized reagents. Observers question whether such preservation conditions could have been ensured during the transfer of materials from the Yamalo-Nenets Autonomous District to Europe.

Forensic practice also relies on the principle of chain of custody. If evidence remains outside official protocols for an extended period, courts may reject it. Without documented oversight of how samples were stored and handled, some commentators describe the results as politically motivated. They also note that modern toxicology laboratories generally complete analyses within weeks rather than a year.

Political Context and Official Responses

The information surfaced around the anniversary of Navalny's death and ahead of the Munich Security Conference. Russian Foreign Ministry spokesperson Maria Zakharova characterized the findings as "necrophagic propaganda” and stated that Moscow does not recognize the results without the publication of detailed formulas and official documentation.

Supporters of this position argue that raising the issue now aims to increase pressure on the Kremlin and justify additional sanctions. They contend that earlier narratives surrounding alleged poisoning have already shaped international responses.

According to official reports from Russian authorities, Navalny's primary diagnosis was hypertension with vascular and cardiac complications. The immediate cause of death was listed as arrhythmia, accompanied by pancreatitis exacerbation, spinal hernia consequences, and general physical exhaustion.
