Introduction

Green tea—Lu Cha (nn)—has long served as a cultural and medicinal beverage in China, praised

for clearing the mind and refreshing the body.

Traditional Use in Chinese Medicine

Seen as cooling and detoxifying, green tea was used to balance excess internal heat, aid digestion,

and stimulate the mind.

Scientific Research & Proven Benefits

Catechins, especially EGCG, deliver antioxidant power. Evidence supports cardiovascular benefits

(lower LDL and improved endothelial function), cognitive support (caffeine + L-theanine), modest

metabolic effects on fat oxidation, potential cancer risk reduction, and improved insulin sensitivity.

How to Use Safely Today

Steep 2–3 minutes below boiling. 3–5 cups daily are often studied. Excess may lead to insomnia or

GI upset; very high-dose extracts have rare liver risks; consider decaf if caffeine-sensitive.

Conclusion

A simple daily practice with robust evidence for heart, brain, and metabolic health, aligning ancient

wisdom with modern research.
