Abstract :
Coffee and tea are one of the most popular drinks in Indonesia. Coffee and tea
contain caffeine. Caffeine is safe for consumption but if consumed in excess it can
cause kidney problems. The maximum limit of caffeine in foods and beverages
allowed is 150 mg/day. The purpose of this study was to determine the
histopathological effect on the kidneys of white rats Rattus norvegicus after
steeping coffee (Coffea cenephora) and black tea (Camellia sinensis L). This
study is an experimental study with 7 treatment groups, namely 1 control, 3 coffee
treatments and 3 tea treatments. Kidney tissue was observed macroscopically and
microscopically. The results of the SPSS test with the Mann-Whitney test of
steeping coffee and tea had an effect on the histopathological picture of the kidney
of Rattus norvegicus rats in the form of degeneration and pycnotic.
