A Ministry of Herbology Wizard Health Warning

"This Species is no longer Safe or Viable for use in the gye potency for Transfiguration Potion Formulas."
—A Ministry of Herbology Wizard Health Warning[src]

Wizard Health Warnings were warnings, issued by the Ministry of Herbology, that were posted around major wizarding locations, in order to prevent plant-related health scares among wizarding society. One such public warning was posted on a wall at Diagon Alley in the summer of 1991.[1]
