El estudio fue realizado por Patricia Murphy, del Center For Complementary and Alternative Medicine de la Columbia University . Se basó en una muestra de 16 mujeres, entre 20 y 32 años, que tomaban anticonceptivos orales de baja dosis al comienzo de la investigación que duró cuatro meses.
Durante los dos primeros meses, las mujeres tomaron un placebo de hierbas y se les midió los niveles de progesterona en sangre. Los otros dos siguientes meses, tomaron hierba de San Juan y se les volvió a evaluar el nivel de progesterona en sangre.
En la fase de placebo, sólo una mujer presentó niveles elevados de progesterona, lo que indicaba que había tenido ovulación a pesar de tomar el anticonceptivo. Sin embargo, cuando consumieron la hierba de San Juan, tres de las mujeres alcanzaron altos niveles de progesterona.
Aunque los resultados son muy significativos, la autora del estudio considera que todavía son necesarios más estudios para obtener datos más específicos.
