Chenpi is mostly taken internally and has no special effects when made into pillows. Chenpi is pungent, warm and aromatic in nature, and has the effects of regulating qi and strengthening the spleen (regulating qi and strengthening the spleen), drying dampness and resolving phlegm (removing phlegm from the body by drying dampness). If medication is needed, it should be directed by a medical professional. Previous studies have shown that citrus fruits contain substances that have a protective effect on neurons, but this requires large doses of extraction and purification to achieve a therapeutic effect, so simply making pillows from Chen Pi in life will not have a specific therapeutic effect. If the peel is made into a pillow, its volatile odor may also affect the sleep, and even skin sensitivities are also prone to allergic reactions, so it is recommended that daily life using cotton pillows can be, without the pursuit of a certain gimmick with the pillow.
