Among the Kava peoples of Vanuatu and Fiji, as well as Samoan and Hawaiian communities, the traditional beverage was prepared from the peeled root or rhizome by pounding or grating fresh material, mixing it with cool water, and filtering the liquid through coconut husk fibers before drinking; this cold‑infusion method was recorded by Lebot, Merlin, and Trilles in 1992, and the same preparation was reported from Micronesia by McDonald et al., 2013. In Tongan practice, kava was taken in a smaller volume as a chewing‑orally held decoction or “mouthwash,” according to Weisler, Bolin, and Skye in 2005, while in early Caribbean descriptions attributed to Pittier in 1912, the ground root was stirred with water and consumed as a drink; all of these forms involve aqueous extraction from the root/rhizome, not hot decoction. In northern Vanuatu, the plant was also prepared as a topical poultice of crushed fresh root applied to swollen joints or wounds, a practice described by Sale et al., 2003. Across these contexts, the primary preparation was a cold infusion from the peeled root or rhizome, sometimes made as a decoction by boiling sliced root in water for a short time, especially in later Cook Islands accounts compiled by McDonald et al., 2013. The same three plant parts—root, rhizome, and peeled stump—are consistently noted across the Pacific, reflecting careful separation of the pharmacologically active inner core from the fibrous outer bark, which can reduce the concentration of kavalactones in the final drink. The drink’s gradual, calming onset and numbing of the lips, tongue, and throat are its defining sensory cues, and by custom the beverage is poured into communal bowls, gulped rather than sipped, and spat to minimize its effect, practices highlighted by Lebot, Merlin, and Trilles, 1992.

For a practical drink preparation, use approximately 25–30 g of peeled, fresh root or rhizome per person; grate or finely chop, mix with 250–300 mL of cool water, stir well, and squeeze the pulp through cloth to filter, discarding the fiber; if a decoction is preferred, simmer 30 g of sliced root in 500 mL of water for 5–7 minutes, cool, then filter; either form can be consumed fresh or kept refrigerated for up to 24 hours. Note that a single serving contains approximately 100–250 mg of kavalactones depending on material and strength, and many communities avoid taking more than one serving daily; kava may cause drowsiness and photosensitivity, and it is contraindicated in pregnancy and breastfeeding and in people using medications metabolized by CYP1A2, 2C9, 2D6, or 3A4, according to Sarris et al., 2013. The beverage is usually taken in the early evening for social and ceremonial relaxation, and while reports of hepatotoxicity concern concentrated extracts used outside customary drink preparation, the standard cold infusion used by Pacific peoples has a long record of relatively safe use, Lebot, Merlin, and Trilles, 1992.

The activity of kava is attributed to a set of resinous kavalactones—kavain, dihydrokavain, methysticin, and dihydromethysticin—compounds that are well characterized in phytochemical surveys of the species, Lebot, 1999, and pharmacologically linked to GABAergic modulation and mild muscle relaxation; these lipophilic constituents partition efficiently into the aqueous drink because fresh root preparation and brief boiling promote both dissolution and suspension, and the numbing sensation of the drink reflects their interaction with sensory nerves. Piperidine alkaloids such as pipermethystine occur at low levels and are more concentrated in the bark, reinforcing the practice of peeling, as reviewed by Lebot and Hooper, 2009. The drink’s bitterness and aroma arise from a small complement of terpenoids and other minor constituents, though the central pharmacology is kavalactone driven, not broad‑spectrum toxicity, Lebot, 1999.

Modern relevance: kava remains commercially available both as whole‑root preparations for home brewing and as standardized extracts used in clinical research on anxiety, with growing interest in solvent‑aware processing to maintain kavalactone profiles and minimize undesirable constituents, Sarris et al., 2013; in its original Pacific context, the beverage continues to be brewed and shared, its preparation and protocols shaped by local customs and the need to balance efficacy with safety.
