Toxicity and traditional medicine
In common with other Crassulaceae (such as the genera
Tylecodon,
Cotyledon and
Adromischus), some
Kalanchoe species contain
bufadienolide cardiac glycosides[2] which can cause cardiac
poisoning, particularly in grazing animals.
[3][4] This is a particular problem in the native range of many Kalanchoe species in the
Karroo region of South Africa, where the resulting animal disease is known as
krimpsiekte (shrinking disease) or as
cotyledonosis.
[5] Similar poisonings have also occurred in Australia.

Kalanchoe
The dark green scalloped leaves and large flower clusters of Kalanchoe (Kalanchoe blossfeldiana) make it a welcome, low-maintenance addition to a sunny spot in your home. Its bright red, pink, or yellow flowers bloom for weeks through the winter. Pets may develop vomiting or diarrhea if they sample kalanchoe’s leaves or stems, however.
