Objective To evaluate the safety of sacha inchi (Plukenetia volubilis linneo) as a health food. Method Acute oral toxicity test, genetic toxicity tests, and rats 30 days feeding test were conducted to evaluate the safety of sacha inchi. Results LD50 of sacha inchi were 7940 mg/kg BW for female mice and 9260 mg/kg BW for male mice. Results of the genetic tests, including the Ames test, bone marrow cells micronucleus assay, and the sperm abnormality test, were negative. Results of the 30 days feeding test showed that sacha inchi had negative effects on the weight gain, food utilization rate, blood count, and serum chemistries. Significant pathological injury in the liver of rats was observed. Conclusion Sacha inchi is toxic under the current experimental conditions.
