What Is Kava? Origin, Noble vs Tudei, Forms and How to Buy
Kava is the root of Piper methysticum, a member of the pepper family that farmers in northern Vanuatu domesticated roughly 3,000 years ago. The root is ground, mixed with water, and strained into a traditional drink shared across the South Pacific. Today it is sold in the U.S. as dried root powder, instant (micronized) powder, liquid extracts, capsules, and ready-to-drink shots. Published by Bedrock Botanicals.
This guide covers what kava is botanically, where it comes from, what “noble” means on a label, how the formats compare, and how to judge quality before you buy from our kava products collection.
What is kava, exactly?
Kava (also called kava kava) is a slow-growing perennial shrub in the Piperaceae family, the same family as black pepper. Its scientific name is Piper methysticum G.Forst., and its wild ancestor is Piper wichmannii. Cultivated kava is sterile: it does not reproduce from seed, so every plant is grown from cuttings. Over centuries, Pacific farmers selected hundreds of distinct cultivars this way.
The part that is harvested is the root and rhizome (the underground stem). Growers typically wait about four years before harvest, and many prefer five or more, because the root’s chemical composition matures with age. The name “kava” comes from Tongan and Marquesan and translates roughly as “bitter,” a fair description of the taste. Source: Kava, Wikipedia (botanical summary with primary citations).
Where does kava come from?
Kava originated in northern Vanuatu and spread with Pacific voyagers to Fiji, Tonga, Samoa, Hawaii, and Micronesia. Each region has its own name for it:
| Region | Local name | Traditional setting |
|---|---|---|
| Vanuatu | Kava / malok | The nakamal, a village meeting house |
| Fiji | Yaqona (yagona) | Sevusevu, the formal presentation of bundled roots as a gift |
| Samoa | ʻAva | Ceremonial welcomes and chiefly gatherings |
| Hawaii | ʻAwa | Cultural and religious observances |
| Pohnpei | Sakau | Root pressed with hibiscus bark |
Vanuatu and Fiji remain the largest producers. For more on the cultural history, see our post on the cultural roots of kratom and kava.
What are kavalactones?
Kavalactones are the class of compounds that chemists measure when they analyze kava root. Researchers have identified 18 of them. Six are considered major and make up most of the total: kavain, dihydrokavain, methysticin, dihydromethysticin, yangonin, and desmethoxyyangonin.
Labs often report these six as a “chemotype,” a six-digit code that ranks them from most to least abundant (for example, 423156). The chemotype is a fingerprint of the cultivar and helps buyers and regulators tell noble kava from other types. When you compare products, look for a stated total kavalactone percentage and, ideally, a chemotype on the certificate of analysis.
What is the difference between noble and tudei kava?
Noble kava refers to cultivars that Pacific communities have long favored for everyday drinking. Tudei (“two-day”) kava refers to other cultivars, which Vanuatu reserves for special ceremonies and does not allow to be exported.
Vanuatu’s Kava Act of 2002 lists the approved noble cultivars and limits exports to them. Exported kava must also meet age and farming requirements. Named noble cultivars include Borogu, Melomelo, and Palarasul. The Codex Alimentarius Commission (the FAO/WHO food standards body) adopted a regional standard for kava products as a beverage in 2020, which also centers on noble varieties and root-only material. Sources: PHAMA Plus on the kava export industry; Vanuatu Kava Act 2002 (text).
For a buyer, the practical takeaway is simple: look for “noble” and “root only” on the label, and a lab test that backs it up. We cover this in more depth in an upcoming Noble vs Tudei guide.
Is kava legal in the United States?
Kava is not a controlled substance under federal law. The DEA’s drug and chemical information sheet on kava confirms it is not scheduled under the Controlled Substances Act. It is sold nationwide as a dietary supplement and in kava bars. Source: DEA Diversion Control Division, Kava fact sheet.
Rules outside the U.S. vary. Germany’s 2002 ban on kava products was overturned by a court in 2014. Australia raised its personal import limit to 4 kg in December 2019 and opened a commercial import pilot in December 2021. Bedrock Botanicals sells only to adults 21 and older. Verify your current local law before ordering.
What forms of kava can you buy?
| Format | What it is | Prep | Best for buyers who want |
|---|---|---|---|
| Traditional root powder | Coarsely ground dried root | Kneaded in water through a strainer bag | The traditional method and lowest cost per serving |
| Instant / micronized | Dried, finely milled or dehydrated kava juice | Stirs into water, no straining | Speed and convenience |
| Liquid extract | Concentrated kavalactones in a liquid base | Measured by dropper | Portability and consistent measurement |
| Capsules | Powder or extract in a capsule | None | No taste |
| Kava shots | Ready-to-drink single-serve bottles | None | Grab-and-go format |
If you are deciding between concentrated and whole-root products, read kava extract vs kava powder.
How do you judge kava quality before buying?
- Cultivar type: “Noble” stated on the label, ideally with the cultivar name and country of origin.
- Plant part: Root and rhizome only. The Codex standard and Pacific export rules exclude stems and leaves.
- Lab testing: A certificate of analysis with total kavalactone percentage, chemotype, and screening for heavy metals and microbes.
- Freshness: Packed in sealed, light-blocking packaging with a lot number and date.
- Transparency: A seller who names the source country and posts COAs.

How does kava compare with kratom?
They are unrelated plants. Kava is a Pacific shrub harvested for its root. Kratom (Mitragyna speciosa) is a Southeast Asian tree in the coffee family harvested for its leaves. They have different chemistry, different regulations, and different traditions. Full breakdown: kratom vs kava.
Frequently asked questions
What part of the kava plant is used?
The root and rhizome. Leaves and stems are excluded from quality kava under Pacific export rules and the Codex regional standard.
Where is the best kava grown?
Vanuatu and Fiji are the largest producers. Vanuatu is kava’s place of origin and exports only noble cultivars under its Kava Act.
What does “noble kava” mean?
It means the kava comes from cultivars long favored for everyday drinking in the Pacific, as opposed to tudei cultivars, which Vanuatu does not export.
Is kava a controlled substance in the U.S.?
No. The DEA confirms kava is not scheduled under the Controlled Substances Act. State and local rules can differ, so verify your local law before ordering.
What does kava taste like?
Earthy, peppery, and bitter. The word “kava” itself traces to a Polynesian word for bitter.
