Pharmacognosy, Phytochemistry, related

<p>My D is a junior and is fascinated with plant medicine. She would like to pursue a degree in something that would allow her to do research and work on medicines based on plant chemistry. I have searched and not found anything except graduate degrees. Is anyone familiar with an undergrad degree or have any advice on whether she should choose biochemistry, botany, or something we haven't yet considered? She will of course be ultimately pursuing grad/PHD degree.
As a side note, she's equally interested in a Creative Writing degree.... about as opposite as she can get! lol</p>
