🌿 How to Read the Research

🔬 Clinical Trial (RCT): Human studies comparing an herb to a placebo or control group. These show how herbs may affect people under controlled conditions, though doses or extracts can differ from those used in teas.

📖 Systematic Review or Meta-Analysis: Summaries of multiple clinical trials that help reveal overall trends. They offer a broad view but depend on the quality and size of included studies.

🌿 Traditional & Observational Use: Centuries of use or real-world data showing how certain herbs have been part of cultural wellness practices. While not cause-and-effect evidence, they provide valuable historical and safety context.

💫 Takeaway: Science continues to explore why these time-honored botanicals support clarity, rest, and balance. Understanding different study types helps you interpret results with curiosity rather than certainty.
