The snake was not demonic creature requiring extermination but beneficial being associated with healing, household protection, and medical knowledge. The Baltic serpent traditions particularly honored žaltys—the grass snake dwelling beneath thresholds, fed milk by respectful households, protected from harm through taboos whose violation brought illness and misfortune. The snake symbolism in medicine reflected practical observations—serpents were found near healing springs with genuine therapeutic properties, snake shedding demonstrated transformation and renewal processes parallel to disease recovery, certain snake behaviors correlated with weather patterns affecting human health. The serpent medicine was not worship of reptile but recognition of empirical associations between ophidian presence and healing phenomena.
