Science Cafe: Poisonous Plants: Live and Let Die

  • Thursday, October 17, 2019
  • 7:00pm - 8:30pm

All plants are poisonous — and no plants are poisonous — it’s simply dose-dependent! There are plants which, when ingested, can block the nervous system for treatment of many ailments, but too much induces coma and possible death. Phytochemicals are chemical compounds, produced by plants, that have evolved to kill or debilitate what or who might eat them. This co-evolutionary arms race between plants and animals dates back millions of years and has no end in sight. Join us to hear how humans have learned to utilize plant poisons for good, bad and ugly purposes!
