Benefits of Liquid Extracts Liquid extracts work faster and more completely than other forms of supplementation. There are no pills to swallow, no herbs to press, or tea to steep. Plus, liquid nutrients are absorbed quickly, so they get to work right away. What's more, liquid extracts preserve active constituents and have a very long shelf life. They are also the ultimate in convenience - just add them to water, tea, or juice and enjoy a tasty, nutritious boost at home, work, or on-the-go. Our Hyssop Herb liquid extract is packaged in a brown, light-resistant bottle with easy-to-use dropper. Stay strong with Hyssop Herb liquid extract.
