Share a bowl of kava with friends and you'll notice the same thing every time: shoulders drop, conversation slows, the room feels warmer. Pacific communities have been preparing kava this way for centuries, long before anyone had a name for the compounds responsible. That effect comes down to a group of compounds in the kava root called kavalactones, and understanding a bit about them explains why this plant has mattered across the Pacific for so long.
What kavalactones actually are
Kavalactones are natural compounds found in the root of Piper methysticum, the kava plant. They're responsible for kava's effects and for the mild numbing feeling on your lips and tongue after a bowl. Researchers have identified around 18 kavalactones in total, but six make up most of what's in a typical root:
- Kavain
- Dihydrokavain
- Methysticin
- Dihydromethysticin
- Yangonin
- Desmethoxyyangonin
People in the kava world call these six the "kavalactone big six." The ratio between them changes depending on the plant variety, where it was grown, and how old it was at harvest, which is part of why two batches of kava can feel noticeably different from each other.
How they work
Researchers are still studying exactly how kavalactones produce that effect. What kava drinkers consistently describe is a clear-headed, sociable kind of relaxation, quite different from the fog alcohol or sedatives bring.
Within the kava community, people often talk about "heady" and "heavy" kava. Heady kava, generally higher in kavain and yangonin, tends to bring more mental clarity and a lift in mood. Heavy kava, with more dihydrokavain and dihydromethysticin, leans toward physical relaxation. Most noble kava, including ours, sits somewhere in between.
Kavalactones are also fat-soluble rather than water-soluble, which is why the traditional method of preparing kava (kneading pounded root in water, then straining it through cloth) isn't just ceremony. That kneading action genuinely helps pull the compounds out of the root fibre and into the water you drink.
Kava is a supplement and not a medicine, and research into how kavalactones work is ongoing. If you're taking medication or have health concerns, it's worth a chat with your doctor before adding kava to your routine.
Why kavalactone content varies so much
Kavalactone content and balance depend on the variety of kava plant, growing conditions, plant age at harvest, and which part of the root gets used (lateral roots tend to carry more than the central stump). This is why noble kava varieties, cultivated over generations specifically for their kavalactone profile and long history of safe use, drink so differently from tudei kava, a lower-quality variety best avoided altogether.
Sourcing matters just as much as variety. Kava that's grown, harvested, and dried with care gives you a far more consistent, pleasant bowl than kava of mixed or unclear origin.
Where our kava fits in
We hold our own kava to that standard. Our signature kava is a noble variety sourced directly from growers in Fiji, harvested mature and processed to keep its natural kavalactone content intact, so what ends up in your bowl is close to what came out of the ground.
Next time you're pounding, straining, or mixing a bowl, you'll know a little more about what's actually happening in it. If you'd like to taste the difference good kava makes, have a look at our kava.
