Acupuncture does not involve injections. No substance is in the needles. Some veterinarians may use injections of Vitamin B12 etc and call this acupuncture or aquapuncture but it is not acupuncture and will not work as acupuncture except is so far as the insertion of a needle by itself will activate an acupuncture energy response. This is also happening with scar tissue therapy where injections are used. This is not likely to be any more effective than a dry needling acupuncture treatment.
Some people use injections and call it acupuncture as they do not have the necessary training to know how acupuncture really works. They cannot feel the energy and so cannot tell when the energy shifts, as when actual acupuncture is working.
Some veterinarians say they are practitioners of acupuncture but always prescribe some veterinary medicines for the same symptoms so they are using the word ‘acupuncture’ to widen their practice and make more money. This is a shameful practice and also shames acupuncture.
Redlight torches and lasers do have healing effects and their promotion should not be mentioning acupuncture. Acupressure maybe.
Acupuncture requires sensitivity, and training in the ability to feel chi and work with the movement of the different types of chi. Each person has chi and the quality of this must be developed. Trainings in Acu-energy healing will improve this and also trainings in Reiki.
Homeopathic injection is also not acupuncture, but homeopathy, and the two should not be confused. The homeopathic may be injected into acupuncture points but this would not give a better result than injection any where else.
Homeopathy and acupuncture work well together just as acupuncture and chiropractic work well together.
