A little of our history

We now stand on the verge of a great new age in magnetic science and its applications, a tool that has been provided by Mother Nature itself.

Quote of  one of the voices of the experts “Dr. Ralph U. Sierra.”  

It all started back in 1967. Dr. Ralph U. Sierra was 63 years old.  He was struggling with two health situations: Merniere’s disease and an enlarged prostrate. 

Dr. Ralph Sierra was the first Chiropractic doctor in Puerto Rico.  He is considered the Father of Chiropractic and Biomagnetism in Puerto Rico.  In 1967, he began his research with Albert Roy Davis, Florida, that aided Sierra with his condition and cured him with the application of a dominoe magnet to his ear and drinking magnetic north water with sodium bicarbonate.  He started doing research with magnets with him, my mother, aunts and of course, his daughter, me Dr. Irma Sierra. 

As the pioneer of Bio-Magnetism, he became an international speaker on this Science, travelled to many US States, Canada, South America, Mexico, Dominican Republic, and even Egypt.  He incorporated Puerto Rico Scientific Research Laboratory where many scientist, researchers and Medical doctors from all over the world, US, Canada, Australia, France, Japan, China, visited him to exchange studies, research and knowledge.  This happened during the decade of 1970's.  They all agreed magnetic energy causes physiological effects in the living systems. The lab was in a private section of our residence, as was his Chiropractic practice.  In the morning he attended patients and in the rest of his time he was in the Lab. 

Hundreds of interviews on television programs, such as,  "De Todo un Poco" with Ramiro Martinez,  Elena Montalvan, Telemundo, also radio, and many United States newspapers.  His research is published in 2 books, The Body Electric and in Dr Buryl Payne Magnet book.  He also contributed his research to Roy Davis that was published in his book Anatomy of Biomagnetism.  Later his name as a Co-author was eliminated and I remember how he felt when he received the book and read his name was changed for someone else.  That ended the relationship he had with one of the authors, his participation of the book he aided and was not given the credit he well deserved! 

Dr. Sierra designed magnetic bands that he personally prepared for his patients, and these became famous with professional sports players, “The Magic Bands of Dr. Sierra”, as they wore them in the fields for their injured joints.  Let me tell you, the magnetic supports that you see manufactured today were because he, Dr. Ralph Sierra, had the courage to come out to the world and say, north magnetic energy works!  After school, I spend endless hours with him; learning and helping him prepare the flexible magnetic back and neckbands.  I even prepared the shipping for the orders received from the lectures and articles he was exposed. 

Dr. Sierra, Ralph, passed away late 1982 after a fall he received trying to apply a postively charged magnetized nail into the trunk of a mango tree because it was not producing mangoes.  Later that tree always produced mangoes, and sweet! Along with Dr. Battacharya, he wrote Power in a Magnet, and it was a hit!  Later he wrote Energía Magnética. 

Then in 1984, I received my Chiropractic Physician and started my practice with all his equipment.  My mother, Irma also his aid, and by then mine, helped me with applying the Electro-Magnetic therapy to the patients, as we both kept preparing the magnets for sale.  Yes you read correctly, Electro-Magnetic therapy, he hand made a pEMF back in the 1970's!!! Ahead of his time!  All the images are in his original book, Power in a Magnet that you can purchase online.  The new revised Power in a Magnet is 2 books in 1. His book is in the back pages. 

Soon after, I married Jorge C Jarrot, my right hand, with an Applied Electronics degree and always interested in Dr. Sierra's research.  When he was in High School, Sierra helped him with a Science Fair experiment on magnetic and pyramid energies.  Later he became a Chiropractor too.  Now, 2020, our 3 children, all grown up are also Chiropractors as well, 3^rd generation!  They are following his grandfather and parents legacy, and quite well!  The Jarrot Sierra’s!

As you know,  manufacturing of magnetic products became very popular in the 1980’s. Taiwan, China, Japan, Canada, Australia, Europe and United States manufactured magnetic products, most of which are with Dr. Sierra’s specification, north (-) to the skin.   I say most because we are always buying and researching these products found in the web, that look like ours, we found that most of the magnetic products made, that are easily available to the general public, are missing the therapeutic potential needed to make a change.  The consumer must be careful when purchasing from another source as these products as we have encountered that: one or more magnets can have no strength, can be with the wrong polarity, or are so weak that at an inch there is no magnetic energy or force.   We, in Healt Magnetic Store & More, always, carefully evaluate the magnetic strength, polarity and designs, THE INVISIBLE MAGNETIC FORCE that can travel and penetrate the physical body.  Be aware of the imitations, replicas or the look alike and be certain you purchase from a qualified and credible source.

That is the purpose to orientate you about us, and why Health Magnetic Store was established and to remind some and teach the new generation who Dr. Ralph. U. Sierra is.
