The root of Piper methysticum from the South Pacific, rich in lipid-soluble kavalactones (kavain, dihydrokavain, methysticin). Kavalactones positively modulate GABA-A receptors, inhibit voltage-gated sodium and calcium channels, and produce profound physical and mental calm without impairing cognitive acuity or causing dependence.
