Herbal pillows are small cushions filled with a variety of dried herbs, flowers, and other natural materials. They are often used for their soothing scents and potential therapeutic benefits. Common ingredients include lavender, chamomile, and peppermint, which are believed to promote relaxation and improve sleep quality. These pillows can be placed under the head, near the pillow, or even used as decorative items in the home. When heated or placed in a warm environment, herbal pillows can release their fragrances, creating a calming atmosphere. They are a popular choice for those seeking natural remedies for stress and sleep issues.
