Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's something worth knowing about this pairing. Glucagon isn't a daily pill you take to lower blood sugar. It works the opposite way: it's an emergency rescue treatment that tells your liver to dump stored sugar into your blood, which pulls you out of a dangerous low. So the concern flagged here is really about hibiscus and your routine diabetes medicines, since hibiscus may gently nudge blood sugar downward on its own.

For glucagon itself, hibiscus isn't likely to weaken its rescue effect in any meaningful way, and this caution is theoretical, based on how things work rather than proven studies. Still, if you keep glucagon on hand, it's smart to mention any regular hibiscus use to your pharmacist or doctor so your overall blood sugar plan stays safe.

Hibiscus sabdariffa is a tart, cranberry-flavored plant most often consumed as a tea, and its best-studied use is for mildly lowering blood pressure.
