From Freemasonic writer Laurence Gardner's book Genesis of the Grail kings Page 162

In the days of ancient Sumer, the Anuists perfected and elaborated a ramifying medical science of living substances, with menstrual Star Fire being a vital source component. In the first instance, this was pure Anunnaki lunar essence called Gold of the Gods, but later, in Egypt and Mediterranea, menstruum was ritually collected from sacred priestesses (the Scarlet Women) and was dignified as being the ‘rich food of the matrix’. The very word ‘ritual’ stems from this custom, and from the Sanskrit word ritu—the ‘red gold’ (sometimes called ‘black gold’).” Endocrinal supplements are used by today’s organo-therapy establishment, but their inherent secretions (such as melatonin and serotonin) are obtained from the desiccated glands of dead animals and they lack the truly important elements which exist only in live human glandular manufacture.”
