Black cohosh
Black cohosh — 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
Actaea racemosa L. (syn. Cimicifuga racemosa) — rhizome and root (Cimicifugae racemosae rhizoma)
Šeit grupēts sadaļā Joints, urinary tract and hormones. Regulējuma nostāja:EU herbal monograph — traditional use, with a mandatory liver warning.
Ko pierādījumi apstiprina
Reģistrētā indikācija:Relief of menopausal complaints such as hot flushes and profuse sweating.
Black cohosh is the most widely used non-hormonal herbal option for hot flushes, and the one carrying a regulator-mandated liver warning on the pack. The herbal committee at the European Medicines Agency reviewed reports of liver injury associated with black cohosh products and required them to warn users to stop and see a doctor if signs of liver damage appear — unusual tiredness, yellowing of the skin or eyes, dark urine, upper abdominal pain, loss of appetite. Cases are rare and causality in many of the reports is uncertain, but the warning stands and it is the single most important thing to know before starting. On efficacy, the trials for hot flushes are mixed; a traditional-use registration does not imply proven benefit, and it is not a hormone, not a treatment for osteoporosis, and not a substitute for a conversation about menopause options.
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
Osteoporosis prevention, vaginal dryness, or vaginal bleeding of unknown cause — which always needs investigating first.
Forma, stiprums un cik ilgi
Standardised dry extracts of the rhizome in tablets and drops. Species substitution with Asian Actaea species has been documented in commercial products, which is one argument for buying registered medicines rather than unregulated supplements.
Ilgums.Monograph texts limit continuous use without medical advice; anyone using it for months should be doing so with a doctor who knows.
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, rash, headache and weight gain are reported. The important one is liver injury, rare but the reason for the label warning.
Kam no tā jāizvairās
Adults only, and not in pregnancy or breastfeeding. Anyone with liver disease should avoid it. Anyone with a history of breast cancer or on hormone-sensitive cancer treatment should not start it without the oncology team.
Mijiedarbība ar zālēm
| Medikaments vai viela | Kas ir aprakstīts |
|---|---|
| Anything else that stresses the liver | Combining it with anything else that stresses the liver — other implicated botanicals, heavy alcohol, medicines with a known hepatic signal — stacks a risk that is already the reason for the warning on the box. |
| Cancer and hormone-blocking treatment | Anyone on tamoxifen or another hormone-sensitive cancer treatment should not add it without their oncology team's agreement. The interaction question is unsettled; the stakes are 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.
