In addition, Feng Shui also believes that medicine is a kind of energy with strong magnetic field and energy field. If the medicine is eaten by others before it is finished, the energy of the medicine will be dispersed to different people, leading to chaos in the energy field, which is not conducive to health.
To sum up, it is not a wise choice to eat other people's leftover medicine. If you need to take medicine, you'd better choose a brand-new medicine and take it correctly according to the advice of a doctor or pharmacist.
