Valerian root is a natural remedy that has been used for centuries to improve sleep quality. It works by reducing anxiety and shortening the time it takes to fall asleep, thanks to compounds like valerenic acid that increase calming neurotransmitters in the brain. Valerian root is particularly effective in treating insomnia and anxiety-related sleep issues. It's available in various forms, such as teas, capsules, and gummies, and should be taken regularly for the best results.
