This is the numbing agent I use for my 72mL of magic mouthwash (12mL anbseol (benzocaine 20%), 30mL liquid antacid (aluminum hydroxide+magnesium hydroxide+simethicone), 30mL children’s benadryl (diphenhydramine HCl12.5mg/5mL). Before creating your own, be sure your doctor or dentist says this home remedy is something right for you to try based on your condition and medical history. Dangerous if swallowed (overdose especially risky in children due to both benzocaine and diphenhydramine). THIS IS INFORMATIONAL ONLY NOT MEDICAL ADVICE.
