The following symptoms may occur in case of poisoning with a marsh calla (Calla palustris):

  • increased salivation
  • irritation of the mucous membrane of the mouth and swelling
  • shortness of breath
  • nausea
  • vomiting
  • diarrhoea
  • stomach pain

In the case of very severe poisoning, the following additional symptoms may occur:

  • palpitations
  • heart and circulatory problems
  • kidney problems (increased urination, decreased to no urination)
  • faintness
  • death may occur due to respiratory arrest


While in the case of acute poisoning one should often try to remove the poison from the body, if necessary by vomiting, this is not advisable in the case of the marsh calla (Calla pallustris). This is because the poison can irritate the mucous membranes so much that shortness of breath can occur.

The vet can cool and treat irritated areas and give calcium-containing drinks or even food in case of poisoning with the marsh calla. The administration of painkillers and monitoring of heart and kidney function are other possible therapies.
