Feverfew
Feverfew — 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
Tanacetum parthenium (L.) Sch.Bip. — herb (Tanaceti parthenii herba)
Šeit grupēts sadaļā Joints, urinary tract and hormones. Regulējuma nostāja:EU augu izcelsmes zāļu monogrāfija — tradicionālā lietošana.
Ko pierādījumi apstiprina
Reģistrētā indikācija:Prophylaxis of migraine headaches, after serious conditions have been excluded by a doctor.
The wording of feverfew's registration is the most instructive thing about it. It is a preventive taken daily over months, not something to swallow during an attack, and the indication explicitly requires that a doctor has first excluded serious causes of headache. The trial evidence is inconsistent: a Cochrane review of feverfew for preventing migraine found the evidence insufficient to establish an effect, with the better-conducted trials the least encouraging. Two practical details set it apart. Chewing fresh leaves, the old folk method, causes mouth ulcers and soreness in a substantial share of people. And stopping abruptly after months of use has been described as producing a rebound of headache, anxiety, stiffness and poor sleep — so if you stop, taper.
C — Traditional use only Plausible from thirty or more years of use, which is what a traditional-use registration means. No clinical evidence was required and none has settled it.
Kam tas nav paredzēts
Treating a migraine attack, and any new, sudden, severe or changed headache, headache with fever and a stiff neck, or headache after a head injury — those need urgent assessment.
Forma, stiprums un cik ilgi
Dried leaf in capsules and tablets, sometimes standardised to parthenolide content, which varies widely between products. Fresh leaf chewing is the traditional method and the one that ulcerates mouths.
Ilgums.Prophylaxis is judged over months, not days. Taper rather than stop abruptly after long use.
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
Mouth ulceration and tongue soreness from fresh leaf. Stomach upset, bloating. Allergic reactions in daisy-family (Asteraceae) sensitive people.
Kam no tā jāizvairās
Not in pregnancy — feverfew has traditional use as a uterine stimulant — and not while breastfeeding. Most registrations are for adults only.
Mijiedarbība ar zālēm
| Medikaments vai viela | Kas ir aprakstīts |
|---|---|
| Anticoagulants and antiplatelets (warfarin, DOACs, aspirin, clopidogrel) | Feverfew appears on the bleeding-risk list. Evidence is limited to laboratory work and case reports, and the caution is standard rather than proven. |
| Anti-inflammatory painkillers (NSAIDs) | Regular anti-inflammatory painkillers are the other common ingredient in a migraine cupboard, and medication-overuse headache is a far more frequent cause of daily headache than most people taking them realise. |
Apgrieztais skatījums — sākt nevis no auga, bet no zālēm — ir atrodams zāļu, pārtikas un alkohola mijiedarbību rokasgrāmata, un apkopots par katru augu šajā vietnē.
