The Active Compounds in Kava

Kava contains a group of compounds called kavalactones. There are over 18 different kavalactones that have been identified in the kava plant, but six of them are believed to be the most active and have the most significant impact on the body. These six kavalactones are: 

Desmethoxyyangonin, Dihydrokavain, Yangonin, Kavain, Dihydromethysticin, and Methysticin. They are responsible for the calming and relaxing effects of kava, which have been used for centuries in traditional medicine and cultural ceremonies. However, it is important to note that the use of kava may also come with potential risks and side effects, and it should be used with caution and under the guidance of a healthcare professional.

Mechanisms of Action

Research has shown that kavalactones interact with several neurotransmitters and receptors in the brain, including: 

 GABA-A receptors, dopamine receptors, and norepinephrine transporters. This interaction is thought to be responsible for the anxiolytic and sedative effects of kavalactones. Additionally, kavalactones may also have antioxidant and anti-inflammatory properties. However, it is important to note that there are potential risks associated with kava consumption, including liver damage and interactions with certain medications. Therefore, it is recommended to consult with a healthcare professional before using kava as a treatment for any condition.

Efficiency and Safety

Several studies have shown that kava is effective for reducing anxiety and stress. For example, a 2003 Cochrane review of 11 randomized controlled trials found that kava was effective for reducing anxiety symptoms in patients with generalized anxiety disorder. Another study found that kava was effective for reducing symptoms of anxiety in patients with non-psychotic anxiety disorders.


Kava is a traditional beverage that has been used for its sedative and anxiolytic properties for centuries. The active compounds in kava, called kavalactones, interact with several neurotransmitters and receptors in the brain to produce its effects. While kava has been shown to be effective for reducing anxiety and stress, caution should be exercised when consuming kava, as there are concerns about its safety. As with any supplement or medication, it is recommended that individuals talk to their healthcare provider before using kava.
