Dzērvene
Dzērvene — ko Eiropas monogrāfija patiesībā apstiprina, kam tas nav paredzēts, forma un cik ilgi to paredzēts lietot, blakusparādības un 2 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
Vaccinium macrocarpon Aiton — fruit and juice
Vietējie nosaukumi reģionā, ko apkalpo šī vietne:jõhvikas (ET) · karpalo (FI) · клюква (RU).
Šeit grupēts sadaļā Joints, urinary tract and hormones. Regulējuma nostāja:Food and food supplement; not a monographed herbal medicine for infection in the EU.
Ko pierādījumi apstiprina
Reģistrētā indikācija:Reducing the chance of repeat urinary tract infections in some groups — not treating an infection that is already present.
Cranberry is the rare case where a large, independent systematic review moved the answer. A Cochrane review of cranberry products, updated in 2023, concluded that they reduce the risk of repeat symptomatic, culture-confirmed urinary tract infections in women with recurrent infections and in children, while finding no clear benefit in several other groups — older people in institutions, people with bladder-emptying problems, and pregnant women. The proposed mechanism is proanthocyanidin interference with bacterial adhesion to the bladder wall, and product strength varies enormously, which is why "cranberry" as a category performs less consistently than any single trial. A regional footnote: the Estonian jõhvikas and Finnish karpalo are the native small cranberry, Vaccinium oxycoccos; the fruit in supplements is almost always the larger American species.
B — Traditional use, trials point the same way Registered on long-standing use, and independent reviews of human trials point in the same direction without settling the question.
Kam tas nav paredzēts
Treating an infection. Burning, urgency, fever, flank pain or blood in the urine need to be seen, because an untreated urinary infection can reach the kidneys. Cranberry does not replace antibiotics and does not shorten an infection.
Forma, stiprums un cik ilgi
Capsules and tablets standardised to proanthocyanidin content, unsweetened juice, and sweetened juice drinks, which are mostly sugar and water.
Ilgums.Prevention is by definition long-term, which makes the sugar content of juice products a genuine consideration.
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
Stomach upset and diarrhoea at high intakes. Cranberry is relatively high in oxalate, which is a consideration for people who form calcium-oxalate kidney stones.
Kam no tā jāizvairās
Fine as a food for most people. Anyone with recurrent infections should still have the reason for them looked at rather than only prevented.
Mijiedarbība ar zālēm
| Medikaments vai viela | Kas ir aprakstīts |
|---|---|
| Anticoagulants and antiplatelets (warfarin, DOACs, aspirin, clopidogrel) | UK regulators issued a caution in the early 2000s after reports of raised INR in warfarin patients drinking cranberry juice. Later controlled studies have been largely reassuring, but the standing advice has not changed: keep intake steady and tell whoever monitors your INR. |
| Diabetes medicines and insulin | Sweetened cranberry juice drinks carry a substantial sugar load; unsweetened juice and capsules do not. |
Apgrieztais skatījums — sākt nevis no auga, bet no zālēm — ir atrodams zāļu, pārtikas un alkohola mijiedarbību rokasgrāmata, un apkopots par katru augu šajā vietnē.
Kā pārtika
Šis ir arī virtuvē, tāpēc uzturvērtības rādītājus ir vērts turēt blakus farmakoloģijai: skatiet pārtikas datu lapa par kalorijām un uzturvielām uz 100 g un uz porciju. Kulinārie daudzumi un medicīniskie preparāti ir atšķirīga ekspozīcija, un tieši šī atšķirība parasti ir viss drošības stāsts.
