Uses (San Mateo County Parks prohibits removal of any natural material)

  • Native people made a poultice of the leaves for rattlesnake bites and other wounds
    • Alternative common name snakeroot probably refers to this use

Name Derivation

  • Sanicula (san-IK-yoo-la) – the diminutive of the Latin sanare, “to heal”
  • crassicaulis (kras-i-KAW-lis) – from the Latin crassus, “thick,” and caulis, “stem”; thus “thick-stemmed”

Notes

  • Prickles on the fruit enable seeds to be dispersed by attaching to animal fur or you!
