Dave Bonta's poem takes a sugar pill, a placebo, and treats it as a riddle that won't be solved. The opening question, "Is it or isn't it?", is exactly what a placebo is built on: it might be medicine, or it might be nothing. The speaker keeps trying on new identities for it. It's a "go sign," a "one-bead rosary," a zero from which every other number grows. It's even imagined falling in love with a salt tablet, which turns the pill into a character with feelings.
The tone is playful and dryly funny, but there's an undercurrent of unease. The question "a prophet or the platter / for his savory head?" jumps suddenly to something darker, a biblical image of a beheading. The pill becomes a thing people project meaning onto, whether holy or sinister. The ending, with its double agent that "forgets who it's working for" and a face "about to smile / or about to weep," leaves the mood suspended. The poem never settles, much like the pill itself.
