Kava root comes from the kava plant, native to the South Pacific. It has been used for centuries by indigenous cultures for its calming effects. The root is typically ground into a powder and mixed with water to create a beverage that promotes relaxation and reduces anxiety. The active compounds in kava, called kavalactones, interact with the brain to produce a sense of tranquility without impairing cognitive function. While kava is popular for its soothing properties, it is important to use it responsibly, as excessive consumption can lead to health issues, particularly concerning liver function.
