Samandarin or Samandarine is the main steroidal alkaloid secreted by the fire salamander (Salamandra salamandra). The compound is extremely toxic (LD₅₀ = 70 µg/kg in mice). Poisoning can cause convulsions, respiratory paralysis, and eventual death. Samandarin is also believed to be the active ingredient in Salamander brandy, a Slovenian drink with purported hallucinogenic and aphrodisiac effects.
