Gallic acid has a single COOH branch on it.
en.wikipedia.org/wiki/Gallic_acid

Is their a way to convert the double bond oxygen on the COOH branch and replace it with two hydrogen and not effect the other OH branches around the benzine or is their a cheep chemical like this.
Can something work with Ammonia family and a catalyst to do this or is their a better way.
or will I just loose the other OH branches around the benzine.

The reaction you are looking for is: Reduction of a carboxylic acid to an alcohol

Try google searching that, there are many, many ways to do it and it should be possible in the presence of the other OH groups (these are phenol groups).
