Los expertos advierten contra el uso de la guanábana para combatir el cáncer - zdmaa Los expertos advierten contra el uso de la guanábana para combatir el cáncer
o Nuestra fruta, con su pulpa dulce y sabor distintivo, se cultiva comercialmente para hacer jugos, postres, sorbetes y helados.
También se supone que tiene cualidades medicinales, con afirmaciones en línea de que el extracto de guanábana puede retrasar la propagación del cáncer o hacer que los tratamientos tradicionales contra el cáncer funcionen mejor.
Los expertos advierten contra el uso de la fruta para tratar el cáncer. Si bien la investigación sugiere que la guanábana puede combatir el cáncer, no se ha estudiado en humanos. Como resultado, no hay evidencia de su seguridad o efectividad.
La guanábana se ha relacionado con muchas afirmaciones sin fundamento, dice Daniel Kellman, ND, FABNO, director clínico de medicina naturopática en nuestro hospital en las afueras de Atlanta.
Guanabanas y garras La fruta alta y espinosa proviene del árbol de graviola, un árbol de hoja perenne originario de México, el Caribe y América Central y del Sur. También se le conoce como chirimoya, guanábana y tallo del pie brasileño. Los practicantes de la medicina a base de hierbas usan la guanábana y las hojas del árbol de la graviola para tratar dolencias estomacales, fiebre, infecciones parasitarias, presión arterial alta y reumatismo. También se utiliza como sedante.
Pero las afirmaciones sobre las propiedades anticancerígenas de la fruta han atraído la mayor atención. Un estudio publicado en el Journal of Medicinal Chemistry en 1997 sugirió que los compuestos de guanábana probados en células de cáncer de mama cultivadas eran más efectivos que la quimioterapia para matar las células. Pero sin ensayos clínicos, no hay datos que respalden esta afirmación.
Vínculos con otros trastornos Los más estudiados son los derivados de ácidos grasos de la guanábana denominados acetogenina inmadura. La acetogenina predominante es la ananocina, que, debido a su toxicidad, probablemente no se estudiará en ensayos clínicos.
Cuando se usa por vía oral, la guanábana se considera potencialmente insegura, dijo Kellman, citando dos estudios. Comer la fruta puede provocar trastornos del movimiento similares a la enfermedad de Parkinson, según un estudio de casos y controles en las Antillas francesas. Además, un estudio informa que el té elaborado con hojas y tallos de graviola está asociado con neurotoxicidad.
En general, algunos pacientes con cáncer usan suplementos a base de hierbas para aliviar sus síntomas y tratar su cáncer. Sin embargo, los suplementos a base de hierbas no sustituyen a la atención tradicional contra el cáncer. Además, el uso de suplementos a base de hierbas durante la quimioterapia puede reducir la eficacia de los agentes quimioterapéuticos debido a las posibles interacciones entre las hierbas y los medicamentos.
