EM® is short for Effective Microorganisms®, a brand name referring to a family of microbial-based products using a technology developed by Japanese scientist Dr. Teruo Higa. All living and non-living things have and are made of energy and everything emits a subtle energy of different frequencies or vibrations. Many are not even aware of these vibrations of energy as most cannot feel or see them
but they are can still there and can definitely affect us. The EM® ceramic beads emit their own frequency, far infrared (FIR), the longest rays in the light spectrum. “FIR wavelength is too long to be perceived by the eyes, however, the body experiences its energy as a gentle radiant heat which can pe*****te up to 1.5 inches (almost 4 cm) beneath the skin.” - https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3699878/
Far infrared waves have been shown to offer many health benefits and appear to be unpleasant to ticks and fleas as well.
“FIR emitting ceramics and fabrics Discs and garments manufactured of FIR emitting ceramic material have been applied to the human body (Figure 5). For instance, a blanket containing discs has been reported to improve quality of sleep [34] and single discs were applied to the breasts of women who encountered difficulty in producing sufficient breast milk during lactation [35]. Gloves have been made out of FIR emitting fabrics and there have been reports that these gloves can be used to treat arthritis of the hands and Raynaud’s syndrome [36].” - https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3699878/
All of my collars and bracelets are made using only genuine EM® ceramic beads - https://www.emrojapan.com/what/ - which is the only “active” ingredient that I use, no chemicals or oils and my paracord is Made in the USA. The EM® are considered safe to use on puppies, pets with health issues and humans too as there are no known adverse effects or contraindications. While I cannot offer a 100% guarantee that my EM® ceramic bead collars will protect your pets from fleas and ticks, there is no 100% for any of the other preventative measures either. I do genuinely believe from my experience that they work will but I do encourage you to do daily tick checks and continue to use other natural preventatives as well.
