Leaf Extracts Are a Rich Source of Phytochemicals
Many leaf extracts are prized in supplements because leaves naturally concentrate a variety of bioactive compounds, like polyphenols, alkaloids, and terpenes. Throughout history, different cultures have traditionally prepared teas and tonics from specific leaves—such as green tea or coca—to take advantage of these natural phytochemicals, which can be present in higher levels in leaves compared to other plant parts.
