St. Vincent Ferrer advised wives to carry a small bottle of holy water and use it during arguments with their husbands, thus avoiding conflicts in the home.
He had a lot of common sense because he recommended wives to carry a small bottle of holy water to avoid quarrels with their husbands.
When they began to fight, she recommended them to put the water in their mouths and not to swallow it until he shut up; obviously with this the fight was avoided.
This was called "Fray Vicente's water".
