The theory behind the Longevity Spices pretty well covers it all, the only other supplement is to take a plant fat daily, such as lecithin or Olive oil, etc. The Longevity Page on the web site covers this theory as well. The Longevity Formula pretty well covers herb use, taken daily it should do most of what herbs can do. The individual herbs/formulas can be taken as a treatment, or the Longevity uped in dose until the desired effects are felt.
