As previously mentioned, the active ingredient of G.H.3 is procaine. Procaine is an ester composed of PABA (Para-aminobenzoic acid) and DEAE (diethyl-aminoethanol). Both of these are water soluble B-vtamins. PABA stimulates the production of folic acid and vitamins K and B1. It has the greatest beneficial effects in the hair, glands and intestines. DEAE is a precursor to choline and acetlycholine. These factors are well known for their importance in nerve function (9).

Esters typically are joined by weak covalent bonds. In the case of Procaine, the looseness of the bonds allows the PABA and DEAE to enter the body more easily. Once inside, they separate and pursue their singular missions. PABA has an electrical charge, which makes it difficult to absorb. When joined together in the procaine molecule, however, PABA and DEAE become ionised. Since they no longer have a charge, the body readily attracts and absorbs them (10).
