Desmethoxyyangonin, a Potent Cannabinoid Receptor 2 Agonist, Alleviates Bone Loss in Ovariectomized Mice via Dual Regulation of Osteoblast and Osteoclast Function
Mening'oo G.W., Yuan H., Wang M., Wang W., Ma F., Zhang W., Ma J., Chen J., Jiang Y., Ma X.
Mening'oo et al. (2026) studied DMY in ovariectomized mice, cell models and computer simulations. The data support a CB2-dependent bone effect in those preclinical models, not treatment of osteoporosis in humans or an effect of a kava beverage.
Kava consumption and the rise of sociopolitical complexity in Oceania
Hrnčíř V., Sheehan O., Claessens S., Gray R.D.
83 Okyanusya toplumunun analizi, geleneksel Kava tüketimi ile politik karmaşıklık ve sosyal tabakalaşma arasında pozitif bir ilişki olduğunu göstermektedir. Ancak, sonuçlar bağımsız olmama kontrollerine karşı sağlam değildir. Mekansal bağımsız olmama kontrolünden sonra Kava içme ile sosyopolitik özellikler arasında birlikte evrime dair kanıt bulunmamaktadır. Kava'nın kültürel önemine rağmen, tüketimi muhtemelen sosyopolitik karmaşıklığın ana itici gücü değildi.
Flavokawain A: A Natural MAO-A Inhibitor With Therapeutic Promise for Depression
Pawa V., Shimpi A., Oh J.M., Kadam V., Patil B., Gawli C., Jagtap V., Mathew B., Sudevan S., Ansari I., Kim H., Patel H.M.
Pawa et al. (2026) found selective MAO-A inhibition by flavokawain A in in-vitro enzyme assays (IC50 0.077 µM); an artificial-membrane assay supported possible blood-brain-barrier passage, alongside in-silico modelling. The study tested neither humans nor antidepressant treatment with kava.
Kavain for health promotion and disease mitigation: Pharmacological promise and therapeutic perspectives
Pampita N., Sajeev A., Hegde M., Alqahtani M.S., Abbas M., Kavalakatt J., Sethi G., Bishayee A., Kunnumakkara A.B.
Pampita et al. (2026) is a review of kavain. It summarizes mainly mechanistic and preclinical findings plus limited clinical anxiety data; it calls for further human studies of efficacy and safety across the many other disease areas.

Prevalence and use patterns of kava (Piper methysticum) in a US nationally representative sample
Çalışmada bir pazarlama şirketi aracılığıyla olasılıksız örnekleme kullanıldı (n=2.000; katılımcıların yarısı kava kullandığını bildirdi). Etki ve istenmeyen etki yüzdeleri katılımcıların öz bildirimleridir; toplum geneli insidans oranları değildir. Kava kullanıcılarının %88,1’i kavanın rahatlama ve stres azaltmada etkili olduğunu belirtti; en sık bildirilen deneyimler mutluluk, rahatlama ve arkadaş canlısı hissetmeydi. En yaygın istenmeyen etkiler uyku hali (%15,4) ve terlemeydi (%15,0).
