Carry this FU or tape it in your bedroom to help dissolve sickness energies and speed up recovery. It can also be used as a preventive protection to reduce the chance of getting sick. Great to have one if you plan on a vacation or a business trip. This FU is not for “drinking” and cannot replace medicine, exercise and common sense. If you are facing a big challenge such as cancer or other issues, we have special FU for that in the customized FU section. Please request the specialized FU instead.
