Feverfew
Feverfew — mitä eurooppalainen monografia tosiasiassa tukee, mihin se ei ole, muoto ja aiottu kesto, haittavaikutukset ja 2 lääkeaineinteraktios dokumentoituna.
Tämä on viitesivu, ei diagnoosi eikä resepti. Yrttivalmisteet ovat oikeaa farmakologiaa: niillä on vaikutuksia, haittavaikutuksia ja yhteisvaikutuksia lääkkeiden kanssa. Kerro lääkärille ja apteekille kaikki mitä otat, myös teet ja lisäravinteet, äläkä koskaan lopeta tai muuta määrättyä lääkettä tämän sivun takia.
Mikä se on
Tanacetum parthenium (L.) Sch.Bip. — herb (Tanaceti parthenii herba)
Ryhmitelty täällä Joints, urinary tract and hormones. Sääntelyasema:EU-yrttimonografia — perinteinen käyttö.
Mitä näyttö tukee
Rekisteröity käyttöaihe: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.
Mihin se ei ole
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.
Muoto, vahvuus ja kuinka kauan
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.
Kesto.Prophylaxis is judged over months, not days. Taper rather than stop abruptly after long use.
Tällä sivulla ei ole grammilukua tahallaan. Kasvinosa, uuttoliuotin ja huume-uute-suhde yhdessä määrittävät valmisteen, eikä yhdestä otettu luku kuvaa toista. Perustelu on keskussivulla; sinuun pätevä määrä on sen pakkauksen painettu, jota pidät, ja apteekki lukee sen kanssasi.
Haittavaikutukset
Mouth ulceration and tongue soreness from fresh leaf. Stomach upset, bloating. Allergic reactions in daisy-family (Asteraceae) sensitive people.
Kenen pitäisi välttää sitä
Not in pregnancy — feverfew has traditional use as a uterine stimulant — and not while breastfeeding. Most registrations are for adults only.
Yhteisvaikutukset lääkkeiden kanssa
| Lääke tai aine | Mitä kuvataan |
|---|---|
| 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. |
Käänteinen näkymä — aloita lääkkeestä eikä kasvista — on lääke-, ruoka- ja alkoholiyhteisvaikutusten viitteessä, ja yhteenvedettynä jokaiselle yrtille tällä sivustolla.
