'Co-Ordination.' 

When the success of a plan depends upon its perfect execution, there must be strict coordination between the individuals involved. No program of treatment can relieve the incidence of constipation unless the patient is willing to coordinate his efforts with those of the physician. That is why so many doctors prescribe Petrolagar for their patients. Its pleasant taste and gentle, consistent action are acceptable to patients as well as to the physician. Five types of Petrolagar provide a choice of medication to suit the individual case.

Has product image, illustration, description and application to provide product details.
