The Tree Outside the Door

How One Pharmacognosy Teaching Laboratory Came to Standardise on Guava Leaf

A science and technology studies paper from the School of Emergent Priorities reads 312 final-year project reports filed in one provincial pharmacognosy teaching laboratory between 1998 and 2023, alongside eleven weeks of observation and seventeen interviews. Leaf from a single courtyard guava tree rises from 4 of 29 plant-based reports in the first five-year period to 34 of 61 in the last, carried there by a technician's picking book, an inherited protocol valued because it always returns a result, and a turn towards product formulation, so that the cabinet comes to read as a literature while recording one unvouchered tree.
