a white crystalline powder (trade name Ethocaine) administered near nerves as a local anesthetic in dentistry and medicine

A mild and widely used local anesthetic used in both prolotherapy and trigger point therapy injection solutions. Procaine exerts a wide range of physiological benefits including: the dilation of capillary beds, (which provides increased blood flow), increased delivery of oxygen, nutrients, and proteins to tissue, hydration of dried out connective tissue, reduction of pain transmission, and relaxation of muscle bundles.

Procaine is a local anesthetic drug of the amino ester group. It is used primarily to reduce the pain of intramuscular injection of penicillin, and is also used in dentistry. Owing to the ubiquity of the trade name Novocain, procaine is sometimes referred to generically as novocaine or novacaine.
