Chinese herbal medicine, as the filling material of pillow core, can slowly exert its efficacy in people's long sleep and exert its different effects, which can play a role in health care and even treatment of diseases. My own family used orange peel to dry and shred, and it has been used for three years, with a faint orange fragrance.

Some pillow cores on the market now are mostly divided into four categories:

1, buckwheat hull and other herbs. The pillow core material has good air permeability,

2. Down/cotton. The pillow made of this pillow core is soft and comfortable, but because of this, the supporting force is poor, which is not conducive to the repair of cervical vertebrae and is easy to deform.

3. Latex/memory sponge. This pillow core material has good resilience, which is beneficial to the fixation of the head and has the characteristics of antibacterial and mite prevention. However, the memory sponge can't be wet or dried by water, and it can only be ventilated and dried in the shade. The service life is about 1 to 2 years.

4.Napcon pillow core. This is a new nano antibacterial polymer material, which has a strong cleaning function, so it has good antibacterial and mite-proof characteristics, and has good hygroscopicity and air permeability.
