Manufacturers of Constipation Medication for Bowel Movement.

Products include Petrolagar with Milk of Magnesia.

Constipation is frequently a factor to be contended with in dental treatment. A sluggish bowel allows the absorption of putrefactive toxins and otherwise  aggravates the patient at a time when comfort is most essential to mental and physical composure. As part of a dental treatment, in case of pyorrhea, infection or extraction, suggest the use of Petrolagar with Milk of Magnesia. It effectively eliminates toxic wastes and provides a prolonged alkaline action to combat excess acidity. Petrolagar with Milk of Magnesia does not dehydrate, gripe or nauseate. It is a pleasant tasting, mild but thorough laxative that can be used over a long period of time without increasing the dosage.
