The activator x mystery is solved and this above article reveals what you have to do to to this:
Weston Price was primarily interested in Activator X because of its ability to control dental caries. By studying the remains of human skeletons from past eras, he estimated that there had been more dental caries in the preceding hundred years than there had been in any previous thousand-year period and suggested that Activator X was a key substance that people of the past obtained but that modern nutrition did not adequately provide.
Price used the combination of high-vitamin cod liver oil and high-Activator X butter oil as the cornerstone of his protocol for reversing dental caries. This protocol not only stopped the progression of tooth decay, but completely reversed it without the need for oral surgery by causing the dentin to grow and remineralize, sealing what were once active caries with a glassy finish. One 14-year-old girl completely healed 42 open cavities in 24 teeth by taking capsules of the high-vitamin cod liver oil and Activator X concentrate three times a day for seven months.
