Abstract

Cassava leaves contain sodium (Na), potassium (K), and iron (Fe) which can increase the body's blood pressure. In addition, the chemical content of cassava leaves can also act as an anti-hypertension agent. However, cassava leaves also contain hydrogen cyanide (HCN) which at certain doses can cause toxic effects. This study aims to determine the safety of long-term consumption by observing the damage to gastric organ cells in Wistar rats after administration of cassava leaf extract (Manihot uttilisima Pohl.) for 90 days. Cassava leaf extract was made by maceration method using distilled water as a solvent. This research is an experimental laboratory research with a posttest only control group research design. This study used 36 Wistar rats which were randomly divided into 4 groups consisting of group I (control) given 10 ml/w of distilled water, group II (treatment group) given cassava leaf extract 80 mg/bb, group III (treatment group) given cassava leaf extract 400 mg/bb, group IV (treatment group) was given cassava leaf extract 2000 mg/bb. Organ sampling was carried out after 90 days of treatment, all rats were killed by cervical dislocation, then their stomach organs were taken. To determine the histopathological structure between the control group and the treatment group, the data from the gastric histopathological test of Wistar rats were analyzed using descriptive analysis. did not affect the histopathological structure of the stomach of Wistar rats.
