Most Rife machines are intended for home remedy, and are not approved for medical use. In the U.S., doctors are not allowed to use them in their practice. These regulations do not apply to private users. Obviously, users must not do anything with the machine that might be construed as practicing medicine.
It is terribly important that users not give people false hope. It must be emphasized, when sharing this technology with loved ones, that this is to be embraced as experimental. Testimonials may be sited, but we caution against raising unreasonable expectations.
From a technical point of view, the JWLABS devices are merely delivering audio frequency to the body. In principal, this is indistinguishable from any other audio equipment like a TV or stereo.
It is our understanding that it is perfectly safe and legal for people to use devices of this kind in the privacy of their homes, according to their intent.
If at any time a user realizes a change that is attributed to one of these devices, it is reasonable and expected that a user may report that effect. If it is a significant change to their well being, it may be important that they do so, and the amount of hazard or risk involved should not escalate because of it.
These reports are always considered to be anecdotal evidence, and not of any scientific value. Therefore they are also of no particular interest in medicine, or to medical authority for the purposes of enforcement, lawful or otherwise. Nevertheless, it is routine that two users with the same problem will get similar results. A percentage of users with the same problem will respond differently. Because not all people are the same, it is necessary to always state that results vary from user to user.
