Poison in tooth-sticks, tongue scrapers, mouth fresheners and unguents

A poisoned tooth-stick looks split, pierced or frayed and lacks a brush end; using it causes swelling, severe suppuration and pain in the mouth, and poisoned tongue scrapers and mouth fresheners do the same. Poisoned unguents such as creams, scents or sandal make the face crack or raise blisters and pox-like eruptions.
