Historically used for gastrointestinal symptoms including diarrhea, indigestion, abdominal discomfort, and associated cramping. This combination is considered outdated by current medical standards.
Benzocaine provides local anesthetic effect for pain relief; bismuth subnitrate acts as an antacid and anti-diarrheal agent with mild antibacterial properties; cerium oxalate has historically been used as an antispasmodic to reduce smooth muscle contractions in the digestive tract.
This formulation is not commonly available in modern practice. Bismuth subnitrate has largely been replaced by bismuth subsalicylate. Cerium oxalate use is rare. Safety profile varies by individual ingredients; bismuth compounds can cause darkening of stool and tongue. Consultation with a healthcare provider is essential before use.
