Kava
Kava — mida Euroopa monograafia tegelikult toetab, milleks see ei ole, vorm ja kui kaua on mõeldud kasutada, kõrvaltoimed ja 3 ravimikoostoimes, mis on dokumenteeritud.
See on teabeleht, mitte diagnoos ega retsept. Taimsed tooted on päris farmakoloogia: neil on toime, kõrvaltoimed ja koostoimed ravimitega. Öelge arstile ja apteekrile kõik, mida võtate, sh teed ja toidulisandid, ja ärge kunagi lõpetage ega muutke määratud ravimit millegi siin loetu pärast.
Mis see on
Piper methysticum G.Forst. — root and rhizome
Grupeeritud siin Where the harm is. Regulatiivne seisund:Withdrawn, suspended or restricted as a medicine in much of Europe after reports of severe liver injury.
Mida tõendus toetab
Registreeritud näidustus:It was marketed for anxiety. It is included here as a boundary, not a recommendation.
Kava beverages have a long cultural history in the Pacific islands. The European story is different: standardised kava extracts marketed for anxiety in the 1990s were withdrawn or suspended in several countries after reports of severe hepatotoxicity, including liver failure requiring transplantation. Regulatory positions have shifted back and forth in the decades since and availability differs by country, which is exactly why an internet order is a poor way to settle the question. The awkward part of the case is that the trials suggested a genuine anxiety-reducing effect — an effective product with a rare, catastrophic harm is a much harder judgement than an ineffective one, and that is the honest shape of the kava file rather than a simple story of quackery. Preparation matters too: traditional water-based preparations of the peeled rootstock differ from the acetone and ethanol extracts that reached European shelves.
D — Popular claim unsupported, or safety dominates The better trials are negative, or the substance appears in the literature mainly for the harm it has caused.
Milleks see ei ole
Anxiety disorders, which have treatments with far better-characterised risk. Do not import it to self-treat.
Vorm, tugevus ja kui kaua
Traditional water-based root beverages; ethanol and acetone extracts in capsules, which are the preparations associated with the liver reports.
Kestus.Not applicable — no European regulator is recommending a course.
Sellel lehel ei ole gramme meelega. Taimeosa, ekstraktsioonilahusti ja ravimi-ekstrakti suhe koos määratlevad valmistise, ja ühest võetud number ei kirjelda teist. Põhjendus on sõlmpunktis; teile kehtiv kogus on trükitud pakendil, mida hoiate, ja apteeker loeb selle teiega.
Kõrvaltoimed
Liver injury, which is rare but has been severe and occasionally fatal. Regular heavy use causes a dry, scaly skin condition known as kava dermopathy. Drowsiness and impaired driving, markedly worsened by alcohol.
Kes peaks seda vältima
Avoid entirely with any liver disease, in pregnancy and while breastfeeding, and before driving.
Koostoimed ravimitega
| Ravim või aine | Mida kirjeldatakse |
|---|---|
| Alcohol | The combination increases both sedation and the liver risk, and impaired driving with kava plus alcohol is documented. |
| Sleeping tablets, benzodiazepines and sedating antihistamines | Additive sedation with benzodiazepines, sleeping tablets and sedating antihistamines. |
| Anything else that stresses the liver | Anything else with a liver signal — including alcohol and several medicines — should not be stacked with it. |
Vastupidine vaade — alustage ravimist, mitte taimest — on ravimite, toidu ja alkoholi koostoimete teatmikus ning kokkuvõttena iga ürdi kohta sellel saidil.
