Noble kava has been extensively researched and has been proven safe for human consumption time and again. There have been a multitude of peer-reviewed scientific journal articles published about the potential benefits of kava and its main psychoactive constituents, the 6 major kavalactones (Stay tuned for our upcoming blog post about this!). Rumours of possible liver harm being associated with kava have not only been debunked, numerous papers have shown that yangonin, which is found in all noble varieties of kava, may actually have liver protective effects. Noble kava is easy drinking, mild on the digestive system, and agreeable with almost everyone. Its effects are widely reported as being uplifting, pleasant, smooth, mellow, and satisfying, and the overall subjective experience is entirely enjoyable for the vast majority.
Root & Pestle noble kava powders use only the lateral and basal stems or rhizomes, and never include any part of the rest of the plant, such as stems, nodes, leaves, or peelings. All noble kavas are high in kavain and low in flavokavains and all of them have a chemotype beginning with 42 or 24. Kavain is always more abundant than dihydromethysticin in noble kavas (the K to DHM (or 4:5) ratio is high). (For more information about chemotyping, please check out our blog on the subject).
The term, “Ignoble”, can be applied to any of a wide variety of kavas which have not had their safety for human consumption proven, including so-called wichmanii, tudei (two day), medicinal, or wild kavas. noble kavas are refreshing and normal amounts can be used regularly by almost anyone without undue risk of serious adverse effects. Most ignoble kavas have a 5 as one of the first 2 numbers in the chemotype, and the K to DHM ratio tends to be around 1 or lower.
The Vanuatu Kava Act restricts the export of kava for consumption to noble varieties only, and although all kava exported from Vanuatu has to meet strict biosecurity and food-safety requirements, the finished kava powder product can vary dramatically in quality depending on exactly which plants are used and on how they are processed. We have an upcoming blog entry about this, but you can be confident that Root and Pestle not only make high-quality kava that goes down easily and works great, but we also ensure that every batch of our kava powder consistently exceeds every requirement for safety too.
Root & Pestle use only 100% noble kava in all of our kava powders, both traditional, and instant. We are noble kava specialists; We only buy noble kava, and we only sell noble kava powders. There is no chance of any amount of cross-contamination with Root and Pestle.
