Resumo(s)
‘‘Água-mel’’ is a honey-based product produced in Portugal for ancient times. Several attributes have
been reported to ‘‘água-mel’’ particularly in the alleviation of simple symptoms of upper respiratory tract.
Samples of ‘‘água-mel’’ from diverse beekeepers from different regions of Portugal were studied in what
concerns antimicrobial, antioxidant and antiviral properties. The amounts of phenol and brown pigment
were also evaluated and correlated with the antioxidant activities. A great variability on the levels of
these compounds was found among samples which were responsible for the variability detected also
on the antioxidant activities, independent on the method used. Generally, antioxidant activity correlated
better with brown pigments’ amount than with phenols’ content. The antimicrobial activity found for
‘‘água-mel’’ samples confirm the virtues reported by popular findings. In addition, this work also reveals
the antiviral properties of ‘‘água-mel’’ evidenced by a decrease on the infectivity of the Qb bacteriophage.
