A research study investigating the benefits of different herbs known to calm the nervous system highlights kava, its benefits, and how it works.
Main points:
- Kava (Piper methysticum): A psychoactive plant from the pepper family, used as a tranquilizing beverage in the South Pacific Islands.
- Medical Use: In Germany, it’s an approved medication for anxiety, tension, and agitation, with recommended doses of 60-120 mg of kavalactones for up to 3 months.
- Usage Duration: The 3-month limit suggests exploring other causes for anxiety, including psychotherapy and stress-reduction techniques.
- Popularity in the U.S.: Increasingly used for short-term anxiety and stress relief, including fear of flying and performance anxiety. For example, a 28-year-old screenwriter used it successfully for presentation nerves.
- Benefits: Muscle-relaxing effects help treat headaches, backaches, tension-related pain, and the nervous system.
Research Findings:
- Compared to Placebo: Studies show a significant reduction in anxiety with minimal side effects.
- Compared to Benzodiazepines: Similar effectiveness without the risk of tolerance, withdrawal, addiction, or next-day drowsiness. It may enhance cognitive function in lower doses.
- For Menopausal Symptoms: Found effective in improving anxiety, hot flashes, sleep, and overall well-being.
Kava’s Active Constituents:
- Kavalactones, or kavapyrones, act as muscle relaxants and anticonvulsants, possibly affecting GABA receptors.
Adverse Effects of kava:
- Mild gastrointestinal complaints or allergic skin reactions. Chronic use at high doses can cause kava dermopathy (a yellow rash).
- Interactions: Additive effect of alcohol on impairment and cognition. Possible interaction with benzodiazepine metabolism.
- Dosage Recommendations: For anxiety, 40-70 mg of kavalactones three times daily, not exceeding 300 mg per day. For insomnia, 210 mg of kavalactones an hour before bedtime.
- Caution: Be advised when combining with alcohol or CNS-suppressing drugs. It can be used during gradual withdrawal from benzodiazepines.
The study suggests that, along with the other herbs mentioned in this paper, kava can support the nervous system by acting on the GABA system. This mechanism has multiple benefits for our mental health, including lowering anxiety,

* Please note that the majority of kava research pertains to kava extracts, which often undergo significant processing and may contain additional ingredients and fillers that can influence their efficacy. It is crucial to consider this distinction when reading about kava studies. To draw an analogy, enjoying natural kava as a beverage can be likened to experiencing a freshly brewed cappuccino, whereas kava extracts are akin in functionality to a caffeine pill. Both forms have their unique benefits and can cater to different preferences and needs. While it’s helpful to understand research on kava extracts, please view it critically and remember that natural kava offers a uniquely holistic experience.
