So what I did during my job is grow plants in the greenhouse, different ones, different milkweeds. Some were toxic, including the tropical milkweed, with very high concentrations of these cardenolides. And some were not toxic.
Pe parcursul activității mele am cultivat plante de seră, diferite specii de iarba-fiarelor, unele toxice, ca iarba-fiarelor tropicală cu concentrații foarte mari de cardenolide, altele inofensive.
