Since there were no previous reports that either
coconut water or mauby exert haemodynamic properties,
those subjects taking antihypertensive prescription drugs
were required to continue taking their medication during the
study. Wassertheil-Smoller and Lamport (23) have pointed
to the difficulties and need for careful experimentation in
order to disentangle the true active ingredient(s) and mode of
action in studies of the present type where drug and dietary
factors are combined in the treatment of hypertension. The
results of the present study should propel further
investigations and open the way for studies that are simpler
to interpret. In spite of the need for much more
experimentation, one other factor appears to give further
support to the diuretic theory
