This range of products are designed to assist the harmonising of the energy field, as per Qi Gong & Acupuncture.
Although the Ch'i Energy Products are not claimed to be scientific or indeed to work according to the 'western' science model, they are however 'tuned' according to ancient principles from China and India. The energy of Ch'i or Prana is the focus of these products and therefore it is difficult to measure their responses by conventional scientific machines.
This does not mean that they are no less valuable to the researcher into this field, for which they are intended. For those of you who are interested in these modern products that use ancient techniques, you will be fascinated by an opportunity to research their energies.
