There are many different modalities that can be used to get to the Truth, but there is still only one Truth. In order to answer this question, one must understand how disease enters the body and how it leaves the body. Hering's Laws of Disease and Cure hold true no matter what treatment modalities are used. All disease goes from below to above. All disease goes from less vital to more vital organs.
All disease goes from above to below.
All disease goes from inside the body to outside. Symptoms appear in reverse order. My practice is based on the work of Enderlein and Isopathy. I use the darkfield microscope and the BTA to monitor my patients. I am a Medical Doctor.
