Studies
• Analgesic / Antiinflammatory: Extract study of aerial parts of PP tested in rats and mice exhibited anti-inflammatory and analgesic activities. The antiinflammatory activity was attributed to interference with prostaglandin synthesis. Results also showed low toxicity.

• CNS Depressant Activity: Study of peperomia leaf extract showed dose-dependent depressant effects probably due to psychoactive substances that are CNS depressant.

• Antipyretic: Study of PP leaf extract on rabbits showed antipyretic effects comparable to a standard aspirin.

• Antibacterial: Study of methanolic extract of PP exhibited a very good level of broad spectrum antibacterial activity.

• Phenological Antiedematogenic: P pellucida has a phenological cycle of about 100 days. The aqueous extract is used as antiedematogenic during pheophases 1 and 2 of winter and spring.
