The expression "like a dose of salts" means to act quickly or to speed up a process. It comes from an old medicine that was used to help people who were feeling faint or sick - a sprinkle of salts would wake them up and make them feel better quickly. Nowadays, the expression is used in a more general sense to describe something that has a sudden and powerful effect, often to get someone moving quickly. You might use this expression to describe someone who suddenly wakes up and starts working hard, or a team that suddenly comes together and starts performing well.
