Herbal supplements like valerian root, chamomile, and lavender have been traditionally used to promote relaxation and improve sleep quality. While some individuals may find these natural remedies helpful, their effectiveness can vary, and scientific evidence is limited. Before using herbal supplements as sleep aids, it's advisable to consult a healthcare provider, especially if you have underlying medical conditions or are taking other medications. Herbal supplements can interact with medications and may not be suitable for everyone.
