Applications
Kava-kava for anxiety
In anxiety disorders, the brain is in a constant state of overstimulation—the threshold for alarm signals is lowered, and even the slightest stimulus triggers anxiety reactions. Cavalactones act similarly to benzodiazepines: they activate the inhibitory GABA receptors, reduce the brain’s hyperexcitability, and raise the anxiety threshold—without the potential for dependence and without the cognitive impairment associated with synthetic anxiolytics. Clinically proven; maximum effect after 4 weeks.
Piper methysticum for stress
Chronic stress keeps the central nervous system in a constant state of alert—cortisol and adrenaline levels remain elevated, making true relaxation nearly impossible. Kava-kava calms the central nervous system through the action of kavalactones on GABA receptors. Stress hormone levels drop, leading to a sense of overall relaxation—unlike benzodiazepines, this effect does not impair clear thinking.
Kava-kava for sleep disorders
Sleep disturbances caused by racing thoughts and anxiety occur when an overstimulated nervous system cannot wind down at night. Kava-kava stops these racing thoughts by reducing neural overstimulation, making it easier to fall asleep and stay asleep. It is particularly effective for anxiety-related sleep disturbances—without causing drowsiness the next morning.
Kava for Heartburn
Stress-related heartburn occurs when the sympathetic nervous system overstimulates stomach acid production while simultaneously causing the stomach muscles to spasm. Kava-kava calms the sympathetic nervous system and relaxes the stomach muscles through its muscle-relaxing effect. Stomach acid production returns to normal, and the heartburn subsides.
Kava-kava for headaches
Tension headaches are caused by underlying muscle tension in the neck and shoulder area, which builds up due to chronic stress. The muscle-relaxing effect of kavalactone relieves this underlying tension: the tense muscles relax, blood circulation improves, and the tension headache subsides.
