Dr. Duncan recommended this acid as a preventive of the undue formation of lithic acid (Dublin Quarterly Journal, May, 1865) by its aiding assimilation; hence it should be serviceable in chronic gout, but such a view has not been supported by the experience of others, and, as a rule, gouty subjects are very intolerant of any acid treatment.

There are several other disorders in which hydrochloric acid is sometimes, though not generally used, but in which its good influence on the digestive tract may fairly be expected to relieve.
