What is the ruling on using the two products, Chi Pendant and Biodisc, from a German company, which claim to cure diseases and provide energy?

The Bio Disc and Bio Pendant: These are two products made from treated natural minerals, claimed to generate "quantum energy" and possess health benefits. The permissibility of their use depends on the opinion of specialists. If their benefits are proven, their ruling is the same as that of other medicines.

As for wearing the Bio Pendant, it is not permissible for men. It is also not permissible for women if it bears a cross, the name of Allah, or Quranic verses.

It is advisable to avoid them, even if their benefits are proven, as a precautionary measure to prevent polytheism (shirk) and imitation of the practices of the pre-Islamic era of ignorance (Jahiliyyah), and to suffice with permissible means.
