THE MODERN HOME STUDY COURSE IN NATUROPATHY. BENEDICT LUST, N.D., D.C., D.O., M.D., Butler and Mount Dora, NJ, and New York, NY. (Advertising Pamphlet)
Short Wave Radiation
Scientific Fasting & Dietetics
Commentary by Laurence Layne: There are a few overlapping components in the Home Study training course. Does spinal manipulation mean Chiropractic? if referring to Chiropractic, then it would at a minimum have to be 1895 or later when Chiropractic was established. There were very few Chiropractors before 1900. Lust lists DC–doctor of Chiropractic–as one of his credentials. Also in theory, “Naturopathy” as a term was not used by Lust until 1902. The initials ND behind his name would indicate this course was created after 1902. Licensure as an MD–medical doctor–could have meant that he passed a state medical exam; a number of states required doctors of whatever school, including irregulars like Osteopaths or Eclectics to take the same state boards as MDs.
Home study courses were available for other forms of natural healing in that era. Both Chiropractic and Massage were offered as “home study” at different points. There were also “How-To” books on Osteopathy.
The range of therapies are consistent with what Dr. John Kellogg practiced in Battle Creek, Michigan and what many classic Naturopaths practiced in the United States and later in the United Kingdom.
Short Wave Radiation probably refers to diathermy. Electrotherapy could be a number of applications, but would include the Sine Wave (sinusoidal) Machine. Hydropathy is hot and cold water applications–hydrotherapy. Fasting and Dietetics can refer to simple diet regimens like fiber cereals, but also juicing. Massage at that time would have been Swedish Massage. Colonics, or colon water irrigation, included enemas. Osteopathic technique would have included many soft tissue techniques, not just a high velocity thrust like Chiropractic. Virtually all these modalities (with appropriate training) are within the scope of practice of many modern Massage Therapy licenses (especially Florida).
The fact that this course was “home study” indicates that many of the modalities could be studied through books and manuals. However, proper application would require mentoring and class room learning.
