Tea
A widely consumed beverage with ancient East Asian origins.
Tea is an aromatic beverage prepared by infusion of hot or boiling fresh water with fresh or cured leaves of Camellia sinensis, an evergreen shrub native to East Asia. After plain drinking water, it is the most widely consumed beverage in the world, with a stimulant effect primarily due to its caffeine content. Tea has a long history of use in East Asia, spreading globally through trade and colonization, and has become central to many cultural traditions.

Lore & Background
Tea plants are native to East Asia, with a probable center of origin near the source of the Irrawaddy River. The natural home of the tea plant is considered to be within a fan-shaped area between Nagaland, Manipur, and Mizoram in the west, through China to Zhejiang Province in the east, and south through hills to Burma, Thailand, and Vietnam. Chinese small-leaf tea (C. sinensis var. sinensis) may have originated in southern China, possibly through hybridization, while Chinese Assam-type tea (C. sinensis var. assamica) shows distinct genetic lineages in southern and western Yunnan, with some hybridization with Camellia taliensis. Indian Assam tea likely originated from an independent domestication, sharing no haplotypes with Western Yunnan Assam tea.
Reader's Guide
Tea's significance lies in its role as a global beverage and cultural touchstone. Early credible records of tea drinking date to the 3rd century AD in a Chinese medical text, though physical evidence from the Han dynasty suggests consumption as early as the 2nd century BC. Tea was consumed for medicinal purposes before becoming a recreational and social beverage during the Tang dynasty, spreading to Korea, Japan, and Vietnam. Its introduction to Europe via Portuguese and Dutch traders in the 16th and 17th centuries led to widespread adoption, particularly in Britain, which later cultivated tea on a large scale in colonial India and Ceylon. The etymology of the word tea—falling into the groups te, cha, and chai—reflects the historical transmission of tea drinking and trade from China. Today, tea is consumed in numerous forms, from hot infusions to iced tea and bubble tea, and remains a staple in many cultures.

Frequently Asked Questions
What is tea, exactly?
Tea is a flavored drink made by steeping the leaves of the Camellia sinensis shrub in hot or boiling water. It comes from a hardy plant originally from East Asia and ranks as the second most consumed beverage on Earth after plain water.
Where did tea originally come from?
Tea traces its roots to the border regions of southwestern China, northeast India, and northern Myanmar. The earliest physical evidence dates to the 2nd century BC, discovered in the mausoleum of Emperor Jing of Han.
When was tea first documented in writing?
The earliest credible written record appears in a 3rd century AD Chinese medical text authored by Hua Tuo. That said, the 2nd-century BC physical artifacts suggest the drink was already in use well before anyone put it to paper.
How did tea become a global drink?
Tea reached Europe in the 16th century through Portuguese traders and gained widespread popularity there during the 17th century. From that point, expanding trade routes and colonial networks carried it to virtually every continent.
What gives tea its stimulating, pick-me-up effect?
The primary stimulant in tea is caffeine, which is naturally present in the leaves of Camellia sinensis. This is what sets tea apart from a purely calming herbal infusion and gives it that mild alertness boost.
