Myers' cocktail
Myers' cocktail is an intravenous (IV) vitamin therapy that lacks sufficient scientific evidence to support its use as a medical treatment. The term, Myers' cocktail, is included in Quackwatch's index of questionable treatments. 

The name is attributed to Baltimore physician John A. Myers. Prior to his death in 1984, Myers allegedly had administered vitamin infusions to patients. Despite claims to the contrary, the original formula is unknown.

Naturopathic doctors in the United States and Canada often administer the IV drip in clinics and health spas.
