Kava
Kava — ko Eiropas monogrāfija patiesībā apstiprina, kam tas nav paredzēts, forma un cik ilgi to paredzēts lietot, blakusparādības un 3 zāļu mijiedarbības, kas tam dokumentēta.
Šī ir uzziņu lapa, nevis diagnoze un nevis recepte. Augu izcelsmes produkti ir īsta farmakoloģija: tiem ir iedarbība, blakusparādības un mijiedarbība ar medikamentiem. Pastāstiet savam ārstam un farmaceitam par visu, ko lietojat, tostarp par tējām un uztura bagātinātājiem, un nekad nepārtrauciet un nemainiet nozīmētu medikamentu tāpēc, ka esat šeit kaut ko izlasījis.
Kas tas ir
Piper methysticum G.Forst. — root and rhizome
Šeit grupēts sadaļā Where the harm is. Regulējuma nostāja:Withdrawn, suspended or restricted as a medicine in much of Europe after reports of severe liver injury.
Ko pierādījumi apstiprina
Reģistrētā indikācija: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 The European story is different: standardised kava extracts marketed for anxiety in the 1990s were withdrawn or suspended in several countries after reports of severe hepatotoxicity, including liver failure requiring transplantation.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.
Kam tas nav paredzēts
Anxiety disorders, which have treatments with far better-characterised risk. Do not import it to self-treat.
Forma, stiprums un cik ilgi
Traditional water-based root beverages; ethanol and acetone extracts in capsules, which are the preparations associated with the liver reports.
Ilgums.Not applicable — no European regulator is recommending a course.
Šajā lapā apzināti nav neviena skaitļa gramos. Auga daļa, ekstrakcijas šķīdinātājs un izejvielas un ekstrakta attiecība kopā nosaka preparātu, un skaitlis, kas ņemts no viena, neapraksta citu. Pamatojums ir izklāstīts centrālajā lapā; jums piemērojamais daudzums ir tas, kas uzdrukāts uz iepakojuma, ko turat rokās, un farmaceits to izlasīs kopā ar jums.
Blakusparādības
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.
Kam no tā jāizvairās
Avoid entirely with any liver disease, in pregnancy and while breastfeeding, and before driving.
Mijiedarbība ar zālēm
| Medikaments vai viela | Kas ir aprakstīts |
|---|---|
| Sleeping tablets, benzodiazepines and sedating antihistamines | Additive sedation with benzodiazepines, sleeping tablets and sedating antihistamines. |

Apgrieztais skatījums — sākt nevis no auga, bet no zālēm — ir atrodams zāļu, pārtikas un alkohola mijiedarbību rokasgrāmata, un apkopots par katru augu šajā vietnē.
