Esta es una página de referencia, no un diagnóstico ni una receta. Los productos herbales son farmacología real: tienen efectos, efectos adversos e interacciones. Diga a su médico y farmacéutico todo lo que toma, incluidos tés y suplementos, y nunca suspenda ni cambie un medicamento recetado por algo que lea aquí.
Qué es
Actaea racemosa L. (syn. Cimicifuga racemosa) — rhizome and root (Cimicifugae racemosae rhizoma)
Agrupado aquí bajo Joints, urinary tract and hormones. Posición regulatoria:EU herbal monograph — traditional use, with a mandatory liver warning.
Lo que respalda la evidencia
La indicación registrada: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.
Para qué no es
Osteoporosis prevention, vaginal dryness, or vaginal bleeding of unknown cause — which always needs investigating first.
Forma, potencia y cuánto tiempo
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.
Duración.Monograph texts limit continuous use without medical advice; anyone using it for months should be doing so with a doctor who knows.
Ninguna cifra en gramos aparece en esta página a propósito. La parte de la planta, el disolvente de extracción y la relación droga-extracto definen juntos una preparación, y un número tomado de una no describe otra. El razonamiento está en el hub; la cantidad que le aplica es la impresa en el envase que sostiene, y un farmacéutico la leerá con usted.
Efectos adversos
Stomach upset, rash, headache and weight gain are reported. The important one is liver injury, rare but the reason for the label warning.
Quién debería evitarlo
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.
Interacciones con medicamentos
| Medicamento o sustancia | Qué se describe |
|---|---|
| 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. |
