I found Dr. Kinghorn’s talk very interesting. I’m not sure why, but it’s crazy for me to sit and think about how there are plants out there that could treat/cure diseases, many of which we haven’t discovered yet. It seems pretty extremely lucky that some of the cures for different illnesses or treatments for symptoms have been discovered from basically guessing which plants or parts of plants to test. Maybe there is a more “scientific” approach to this, but it seems like mostly a “guess and check” sort of process. The process of trying to test and approve a new drug seems exhausting as well. I’m not sure I would have the patience for this particular field of research!
