Echinacea
Echinacea — o que a monografia europeia realmente apoia, para que não é, a forma e por quanto tempo deve ser usado, efeitos colaterais e a 1 interação medicamentosa documentada.
Esta é uma página de referência, não um diagnóstico nem uma receita. Produtos herbais são farmacologia de verdade: têm efeitos, efeitos colaterais e interações. Conte ao médico e ao farmacêutico tudo o que toma, incluindo chás e suplementos, e nunca pare ou mude um medicamento prescrito por causa do que ler aqui.
O que é
Echinacea purpurea (L.) Moench — herb and root (Echinaceae purpureae herba, Echinaceae purpureae radix)
Nomes locais na região que este site atende:siilkübar (ET) · punahattu (FI) · эхинацея (RU).
Agrupado aqui em Colds, cough and throat. Posição regulatória:Monografia herbal da UE — uso tradicional.
O que a evidência apoia
A indicação registrada:Short-term prevention and treatment of the common cold.
The best-selling cold herb in the Nordics and Baltics, and the one whose evidence has been argued over for thirty years without resolution. Part of the reason is that echinacea is not one thing: three species are used (E. purpurea, E. angustifolia, E. pallida), root and aerial parts have different chemistry, and pressed juice, tincture and dried extract are three different preparations. Systematic reviews land somewhere around a small possible effect on how often colds occur and an unclear effect on how long they last; NCCIH's summary of the research says the evidence is not strong. The monograph is clear about one thing that matters practically: this is for short-term use started at the first signs, not a tonic taken all winter.
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.
Para que não é
Influenza, pneumonia, sinus infection or any illness with high fever and breathlessness. A cold that gets worse after a week, rather than better, is a reason to be seen.
Forma, força e por quanto tempo
Expressed juice of fresh flowering herb, tinctures, dried extracts and lozenges. Products differ so much that experience with one says little about another.
Duração.Short courses, typically up to about ten days. The monographs do not support continuous seasonal use.
Nenhum número em gramas aparece nesta página de propósito. A parte da planta, o solvente de extração e a razão droga-extrato juntos definem uma preparação, e um número tirado de uma não descreve outra. O raciocínio está no hub; a quantidade que se aplica a você é a impressa na embalagem que segura, e um farmacêutico lê com você.
Efeitos colaterais
Allergic reactions are the notable ones — rash, itching, and rarely severe reactions — and they are more likely in people with existing allergies or asthma. Daisy-family (Asteraceae) sensitivity is the relevant cross-reaction. Stomach upset and a tingling tongue from tinctures.
Quem deve evitar
Monograph texts contraindicate it in progressive systemic disorders including tuberculosis, sarcoidosis, autoimmune diseases, multiple sclerosis and HIV infection, and in people taking immunosuppressants, because it is presented as immune-stimulating. Most preparations are not for children under 12. Not established in pregnancy.
Interações com medicamentos
| Medicamento ou substância | O que é descrito |
|---|---|
| Immunosuppressants and transplant medicines | Echinacea is sold as an immune stimulant while transplant and autoimmune medicines work by suppressing immunity. The two are pulling in opposite directions, and the monograph contraindication reflects that rather than a measured drug level. |
