No. The machine will not make matters worse. Indirectly, however it is not a good idea to use the machine instead of having the sort of care your doctor suggests. Like using it to avoid a surgical procedure that you urgently and clearly need, even though it may be a good thing to try first.
     For people suffering from viral infections like HIV, or hepatitis, it is best to refrain from using the machine for at least a few days before a viral load test, because using the machine will stir up pathogens and other measurable blood factors, which is a normal effect of the device that will throw off the results of most tests of this kind. White cells are also brought out and become much more active. Shattered virus may not be distinguishable from live virus. Increased antigens may appear to indicate changes that are not really correct. This could make it look a lot worse than it really is and cause your doctor to make incorrect judgements about your condition. You will feel fine, but your doctor may wonder how it is that you are even walking around.
     If  conventional tests are the means by which you are measuring your progress, just take leave of the machine for three to five days. The debris in your system will have time to clear out completely and the test will reflect more accurately your true condition.
     The old wives-tale that it has to get worse before it gets better is simply untrue. In professional Rife clinics located in other countries, the sort of reactions that are referred to as a healing crisis or Jarisch-Herxheimer reaction are carefully avoided. These reactions are not desirable and it is routine for us to carefully guide each user through their "beginners sessions" to make sure that they understand how to use the machine correctly. We also do our best to teach each user how to use the machine safely and effectively. When to use the instrument and when not to use it is a part of this process. It is not difficult. Once you understand the basics, it is like riding a bicycle. You will always know what to do and you can apply this knowledge to many other applications that you may need in the future. 
     We are always available to help if you have more questions. Normal business hours are 9 AM to 9 PM Pacific Time, every day. However, JW is usually ready to take calls at 6 AM, and will take calls at any hour if you experience an emergency.
     There is no question that the symptoms of many conditions will increase when over use of the machine occurs. There are various possible reasons why one user can use it for an hour with no side effects, but another may only take 5 minutes comfortably. At the beginning, for most new users, a maximum of 5 minutes per session is the best place to start.
     Do not confuse a JWLABS machine with others. What works with one machine may not work at all when applied to therapy with another. The differences are often quite huge. An hour on one type of device may be no problem at all. JWLABS machines are almost never used for more than 30 minutes at a time. To exceed 30 minutes with any JWLABS model is dangerous for most users.
     There are a number of reliable phenomena that are predictable according to the type of problem a user may be suffering from. If diagnosis is correct, very specific methods of therapy are called for depending on what problems are present. It is even possible for a user to be afflicted with diseases that have Rife applications that are conflicting. These and many other complexities have lead us to establish a standardized beginners routine, and a systematic method of determining how each user will precede with safety and a minimize possible negative symptomatic results.
     In the Rife Therapy portion of JWLABS' web presence, specific in depth descriptions of disease, methods of therapy, frequencies, session duration and cadences are available for registered users. These detailed applications are accessible by password only.
     Rife Therapy is designed to accommodate both the practitioner, and the home user as well. It contains a veritable library of applications that are appropriate for JWLABS machines only. Each user has a customized access to data that is relevant to their condition according to what we know. Such access is tailor made for each user, and should never be used by another user unless specifically suggested.
     When symptoms increase following a session, in most cases this is going to be due to a Hexheimer type reaction. A Jarisch-Herxheimer reaction is defined as:
 
"A transient, short-term immunologic reaction commonly seen following antibiotic treatment of syphilis and less often in other diseases, such as borreliosis, brucellosis, typhoid fever, and trichinellosis, which is manifested by fever, chills, headache, myalgias, and exacerbation of cutaneous lesions. The reaction has been attributed to the liberation of endotoxin-like substances of antigens from the killed or dying microorganisms, but its exact pathogenesis is unclear. Called also Herxheimer's Reaction."

     This reaction has long been observed to be brought on by Rife therapy, although the name has its origins in antibiotic therapy. It should not be confused with toxic reactions caused by over use. A Rife reaction. It is possible to have the effects of both types of reaction at the same time, by the same cause. The most notable difference between these is that the Herxheimer reaction will generally not be repeatable, and it is not cumulative, as is the Rife reaction. In the Rife reaction, the effects can be repeated, and it can also be stored up over time, each subsequent session treating and counteracting the effects of the previous sessions reaction, until the full reaction breaks, or the user stops. The Rife reaction can be much more severe, and may require hospitalization in the extreme case. The beginners routine is designed specifically to avoid the Rife reaction.
