Ethnopharmacological Relevance: Peperomia pellucida (L.) Kunth is an annual weed with a preference to humid places with reduced solar radiation. This plant is mainly distributed in the Neotropics, Africa, Southeast Asia, and Australia. It is popularly employed in the treatment of a variety of health conditions such as abscesses, abdominal pain, skin sores, conjunctivitis, measles, and kidney troubles. Several studies have also described its antimicrobial, cytotoxic, antidiabetic and a variety of other bioactivities.
The Aim Of The Review: The aim of this work is to evaluate, using a critical review, the present ethnomedicinal applications, phytochemistry and pharmacological studies of P. pellucida essential oils (EOs) and extracts from different locations around the world.
Materials And Methods: This review was performed through an online survey of the ethnomedicinal practices, chemical compositions and pharmacological applications of P. pellucida EOs and extracts. The data were mainly obtained from online journals and books published in English, Portuguese and Spanish. The information was collected from websites such as Google, Google Scholar, PubMed, Science Direct, ResearchGate and other online databases that provided more information about this herb.
Results: Peperomia pellucida bioactivities such as antimicrobial, cytotoxic, antioxidant, fracture healing, antidiabetic and anti-hypercholesterolemia have been described in several literature sources. Nonetheless, most reports only provide the phytochemical screening of extracts, which does not allow the identification of the active compounds. From these studies, some reported constituents are not included in the Dictionary of Natural Products (DNP), which raises questions toward their identification. In addition, some biological assays were even performed without standard controls for comparison which also makes these results questionable.
Conclusion: This review evaluates data regarding the phytopharmaceutical potential of P. pellucida. In general, several important aspects were questionable or missing in these manuscripts, which points out the need of more investigation on the pharmacological properties and phytochemical compositions of this herb.

Objectives: This study assessed the electrocardiographic pattern and cardiac inflammatory response of doxorubicin-induced myocardial injury in Wistar rats treated with ethanol extract.
Methods: Female Wistar rats (190-200 g) were assigned into five groups of seven rats each. The Group 1 (Control group) was given rat chow and drinking water while the Group 2 (doxorubicin group) received intraperitoneal administration of doxorubicin (2 mg/kg) once weekly for three weeks.

Article Synopsis
- The study investigates how Peperomia pellucida reduces inflammation in ARPE-19 eye cells exposed to high glucose and advanced glycation end products (AGEs) by exploring specific signaling pathways (NF-κB and PPAR-γ).
- Both the methanolic extract and ethyl acetate fraction of P. pellucida showed no toxicity to the cells and provided protection against cellular stress caused by high glucose levels and AGEs.
- Key phytochemicals in P. pellucida demonstrated strong binding to inflammatory proteins, suggesting their potential role in inhibiting the inflammatory response in these retinal cells.

The formation of advanced glycation end product (AGE) is a risk factor for diabetic retinopathy. Since the current treatment for diabetic retinopathy is accompanied by side effects, preliminary findings have suggested Peperomia pellucida (L.) Kunth as a potential alternative therapeutic option for diabetic retinopathy.
