Piper methysticum
Piper methysticum
Piper methysticum, commonly known as kava, is a plant native to Polynesia where it has been used in traditional ceremonies and social gatherings for centuries. Traditionally, its use was primarily ceremonial or recreational, with no specific recorded medicinal applications. Scientific studies have shown that compounds from Piper methysticum, such as kavain, exhibit diverse biological activities across various pathological conditions; however, these findings are mainly based on preclinical research. Notably, there has been an increase in kratom-containing kava product exposures reported to poison centers from 2011 to 2025, with participants reporting mild effects such as reduced anxiety and sedation. Kavain also shows potential for use as a multi-targeted therapeutic for rheumatoid arthritis by modulating several key signaling pathways and inflammatory mediators. To date, no major safety issues or drug interactions have been recorded for Piper methysticum.
