Herbal sachets are small bags filled with dried herbs, flowers, or spices, often used for their pleasant scents and potential therapeutic benefits. Commonly made from natural materials like cotton or muslin, these sachets can be placed in drawers, closets, or under pillows to freshen the air and repel insects. People often use herbal sachets for relaxation and stress relief, as certain herbs like lavender and chamomile are known for their calming properties. They can also serve as a natural alternative to synthetic air fresheners, promoting a more eco-friendly lifestyle while adding a touch of fragrance to living spaces.
