Sharpens focus and eases heavy meals
What it does
Tea sharpens your focus and helps you bounce back from heavy meals. In TCM, it clears the head and eyes, allays thirst, disperses food stagnation, and transforms phlegm. The bitter cooling quality cuts through fog. Modern research is enormous: catechins, L-theanine, and caffeine combine for focus, blood sugar, and oxidative defense. Eight reviews cover cardiovascular effects.
How to take it
Steep 2–5g of loose tea leaves in 1 cup hot water (80–95°C depending on tea type) for 1–5 minutes. Drink 2–4 cups daily. Avoid steeping over 5 minutes.
Try a cup of green tea mid-afternoon as a focus boost

Where it comes from
Tea (Camellia sinensis) is native to southern China and Southeast Asia, where it's been drunk for over 4,000 years. Legend credits Emperor Shen Nong with discovering it around 2737 BCE when leaves blew into his boiling water. In TCM, tea types differ by processing: green is cooling, white neutral, oolong and black warming. Eight modern reviews cover effects on metabolic syndrome, neurodegeneration, and oral health.
