Psidium guajava, also known as guava, is a medicinal plant that mainly found in tropical or subtropical areas like the Philippines. This plant has been used in treating different diseases and is also known for its medicinal and antimicrobial properties. Despite this, there are only a few numbers of studies regarding the toxicology of P. guajava. In this study, Brine Shrimp Lethality Assay (BSLA) was done to identify if the leaf and bark extracts of P. guajava have toxic effects against Artemia salina (brine shrimp). Results showed bark extracts having an LC50 value of 480.14 μg/mL and leaf extracts with an LC50 value of 949.13 μg/mL, and the mortality rates of brine shrimps for the bark extracts were relatively higher than the leaf extracts. It revealed that P. guajava bark extracts were more toxic than the leaf extracts.
