You can buy cassia seed in a drugstore and make a cassia seed pillow, which takes about 6 to 8 kilograms of cassia seed. Note that before making pillows, cassia seed should be cleaned and dried in the low sun. Then put the cassia seed in the pot and fry it a little until it turns yellow. Then spread the cassia seed cold, put it into the pillowcase, sew the opening with needle and thread, and make a simple cassia seed pillowcase. Then put a cotton pillowcase on it when you use it again.
Is it simple? Health-conscious friends may wish to make their own cassia pillows at home, so that sleeping is safer and more secure. It is worth mentioning that if you feel that the cassia pillow feels hard when you use it, you can add some dried chrysanthemums to it. Doing so can not only reduce the hardness of cassia seed pillow, but also have more obvious eyesight improving effect.
