Abstract :
Indonesia is a tropical country with potential plants that are empirically used as
traditional medicine. One of them is black garlic which is fermented garlic at a
temperature of 40-80°C with a relative humidity of 70-80% for 15 days.
Empirically garlic is used as a medicine for various diseases, such as warts,
hypertension, heart disease, cancer, diabetes. This study aims to determine the
acute toxicity of black garlic which can cause 50% death as measured by the
LD50 value (lethal dose 50%) in male white mice. Black onion extract was
obtained by maceration using 70% ethanol. Acute toxicity test was carried out by
giving treatment to each group, namely Group I as a normal control who was
given CMC-Na 0.5%, Group II was treated with ethanol extract of black onion at
a dose of 2000mg/KgBB, Group III was given treatment with ethanol extract of
black onion at a dose of 2500mg/KgBB, and group IV was given treatment with
ethanolic extract of Black Lanang at a dose of 3000mg/KgBB. Phytochemical
screening showed that the ethanolic extract of black onion was positive for
flavonoids, saponins, polyphenols, and alkaloids. The results obtained in this
study were that there were no deaths of test animals in all groups, but there were
toxicity symptoms, namely soft stools/diarrhea, passive mouse activity, tremors,
hair did not fall out, and weight gain.
