RMF4T7C8–Bromide bottle dating from 1914.

Bromism is the syndrome which results from the long-term consumption of bromine, usually through bromide-based sedatives such as potassium bromide and lithium bromide. Bromism was once a very common disorder, being responsible for 5 to 10% of psychiatric hospital admissions, but is now uncommon since bromide was withdrawn from clinical use in many countries and was severely restricted in others. Dermatological effects include cherry angiomas, acneiform, pustular and erythematous rashes. Stock Photo
