Tea has travelled across continents, shaped cultures, healed communities, and become one of the world’s most universal daily rituals. Its story blends ancient discovery, global traditions, and powerful health benefits. 
Tea’s origin story begins in China around 2737 BCE. According to legend, Emperor Shen Nong was boiling water when leaves from a wild tree drifted into his pot. The aroma intrigued him, he tasted the infusion, and tea was born.
From China, tea spread to Japan, India, Africa, and Indigenous America, becoming a global symbol of healing, hospitality, and ceremony.

How to Drink Tea for Best Health Benefits
To maximise tea’s healing power:
Drink it plain
Avoid sugar and heavy milk as they reduce antioxidant absorption.
Steep correctly
Green tea: 2–3 minutes, warm water (not boiling)
Black tea: 3–5 minutes
Herbal tea: 5–10 minutes
Rooibos: 5 minutes
Pu‑erh: multiple short steeps
Drink 2–3 cups daily
Enough for benefits without overdoing caffeine.
Avoid drinking tea with meals
Tea can reduce iron absorption, especially important for women.
Choose loose leaf when possible
Higher quality, fewer microplastics than tea bags.

Negative Effects of Tea
Tea is generally safe, but there are a few cautions:
Caffeine sensitivity
Black, green, oolong, and pu‑erh contain caffeine. Can cause:
Anxiety
Insomnia
Heart palpitations
Iron absorption
Tea reduces iron absorption,  especially black tea. Drink between meals if you have low iron.
Tannins
Can cause stomach upset in some people.
Herbal tea risks
Some herbs interact with medications (e.g., willow bark, St. John’s wort). Always check if pregnant or on medication.
