kava pepper
Piper methysticum
Piper methysticum, commonly known as kava, is a traditional plant used in Pacific Island cultures. Traditionally, it has been used for various social and ceremonial purposes, including reducing anxiety and promoting relaxation. Scientific evidence suggests that compounds from Piper methysticum, particularly fika (FKA) and kavain, may have potential therapeutic applications, such as managing inflammatory conditions like rheumatoid arthritis by modulating key inflammatory and oxidative stress pathways. However, the data is limited and more research is needed to confirm these findings. Notably, there have been reports of increased serious outcomes from kratom-containing kava product exposures over time, though this does not directly reflect on Piper methysticum itself. No major safety issues or drug interactions have been recorded for Piper methysticum in general use.

What the science says
- Kavain from Piper methysticum shows diverse biological activities across various pathological conditions but findings are primarily based on preclinical studies.
- Kratom-containing kava product exposures reported to poison centers increased steadily from 2011 to 2025.
- The survey found that among participants, kava was used infrequently and was perceived to have mild effects such as reduced anxiety and sedation.
- FKA from Piper methysticum shows potential as a multi-targeted therapeutic for rheumatoid arthritis by modulating several key signaling pathways and inflammatory mediators.
