In addition to theĀ original Schuessler salts numbered 1-12, there are also numbers 13 to 27.
Dr. Schuessler's successors expanded Tissue Salt therapy to include supplementary mineral salts - called the Additional/Supplement Salts. A large proportion of our complaints and illnesses can be treated well with the 12 basic salts through self-medication. The Additional Salts help to further improve the success of the treatment.
