Methysticin is primarily known for its role in traditional medicine, particularly in the Pacific Islands, where it is derived from the kava plant. It is often used for its calming and anxiolytic effects, making it a popular choice for reducing stress and anxiety. Additionally, it has been explored for its potential muscle relaxant properties, which can help alleviate tension and promote relaxation. Some studies suggest it may also have neuroprotective benefits, though further research is needed to confirm these effects. In modern applications, it is sometimes included in dietary supplements aimed at promoting mental well-being and relaxation. However, its use should be approached with caution due to potential side effects and interactions with other substances.
