Legend has it that Emperor Shen Nung, who reigned in China around 2737 BC, discovered tea accidentally while boiling water under a tree.

 

The origins of tea can be traced back to ancient China, where it was first used for medicinal purposes. According to tradition, Emperor Shen Nung, also known as the "Divine Farmer," was a mythical figure considered the father of Chinese medicine and agriculture. Legend has it that Emperor Shen Nung, who reigned in China around 2737 BC, discovered tea accidentally while boiling water under a tree. Some tea leaves from the tree blew into the pot, infusing the water with their taste and aroma. Intrigued by the resulting beverage, the Emperor decided to taste it and found it refreshing and invigorating. This serendipitous encounter marked the beginning of tea consumption in China. However, it's important to note that the scientific process by which the green leaf of the tea plant infuses taste and aroma is not fully understood, as only manufactured leaves like black tea, green tea or oolong tea etc are known to release their taste and aroma.

Legends ascribe the creation of the tea plant to Daruma or Bodhidharma, the founder of Zen Buddhism. Daruma, also known as Bodhidharma, was a Buddhist monk who lived during the 5th or 6th century AD, according to historical accounts.

 

Daruma: Legend and Legacy in Tea Culture

 

Legends ascribe the creation of the tea plant to Daruma or Bodhidharma, the founder of Zen Buddhism. Daruma, also known as Bodhidharma, was a Buddhist monk who lived during the 5th or 6th century AD, according to historical accounts. While the exact timeline of Daruma's life is shrouded in legend and myth, he is widely revered for his role in spreading Zen Buddhism to China and Japan. According to legend, Bodhidharma was born as a prince in Southern India and later traveled to China to spread the teachings of Buddhism. He is often depicted with a distinctive appearance, with large, round eyes and a beard.

 

One famous legend about Bodhidharma involves his nine years of meditation facing a cave wall at the Shaolin Temple in China. It is said that during this time, he developed the principles of Zen Buddhism and laid the foundation for the martial arts practiced by the monks at the temple.

 

According to folklore, while meditating on the banks of Nanking in China, the saint fell asleep. Upon waking up, he was so angry that he punished himself by cutting off his eyelids. Where the eyelids dropped to earth, a strange plant emerged. Its leaves were found to give a brew that could banish sleep. And so, the tea plant was born, and the tea beverage came into being. This mythical tale offers readers a perspective of another realm, adding to the mystical origins of tea.

 

Today, Daruma dolls, which are often red and round with no arms or legs, are considered a symbol of perseverance, resilience, and good luck in Japanese culture. These dolls are modeled after Bodhidharma and are often used for goal-setting and motivation, with individuals painting in one eye when setting a goal and painting in the other when the goal is achieved.

 

Dating back to the Devonian period, approximately 416 to 345 million years ago, the first vascular plants emerged, marking a significant milestone in the evolution of plant life.

 

Tea's Geological Journey: From Ancient Roots to Modern Discoveries

 

Indeed, the discovery of tea by Emperor Shen Nung in 2737 BC provides a glimpse into the ancient origins of tea consumption. However, when considering the broader timeline of plant evolution, it's fascinating to note that tea plants have much deeper roots in Earth's history. Dating back to the Devonian period, approximately 416 to 345 million years ago, the first vascular plants emerged, marking a significant milestone in the evolution of plant life. While it's impossible to precisely determine when tea plants first appeared, this ancient lineage suggests that tea has been intertwined with the natural world for millions of years.

  • Uncertainty surrounds the exact emergence of tea plants

 

The subduction of plates and tectonic movements over millions of years have shaped the Earth's surface, influencing the distribution of plant species and ecosystems.

 

The folklore surrounding Emperor Shen Nung's discovery of tea provides a captivating narrative about early human interactions with this beloved beverage. However, when we delve deeper into the geological history of our planet, particularly considering phenomena like plate tectonics and continental drift, it raises intriguing questions about the origins of tea. The subduction of plates and tectonic movements over millions of years have shaped the Earth's surface, influencing the distribution of plant species and ecosystems.

 

  • Geological processes like plate tectonics and continental drift influence tea's dispersal across regions

 

While we may never pinpoint the exact location of tea's origin, these geological processes offer valuable insights into the complex history of our planet and the interconnectedness of its inhabitants. Just as tectonic movements have sculpted landscapes and shaped habitats, they may have played a role in dispersing tea plants across different regions, contributing to the rich diversity of tea cultures we see today.

Tea Plant Nomenclature and Classification

 

Two Recognized Varieties of Camellia Sinensis

 

  • Botanists initially identified two varieties of Camellia sinensis:
    • Var. Sinensis: China tea, characterized by small leaves.
    • Var. Assamica: Assam tea (Indian), known for large leaves.

 

Recent Genetic Studies

 

Five Distinct Genetic Tea Populations:

 

  • Assamica Varietal Traits: Five distinct genetic populations, showing unique traits.
  • Independent Domestication: Populations originate from a western cluster of wild tea trees.
  • Potential Hybrids: New hybrids can be cultivated from Assam tea, presenting opportunities.

 

The Assamica specimen was collected in 1949 for Kew Royal Botanic Gardens.

The Assamica specimen was gathered in 1949 on behalf of the Kew Royal Botanic Gardens. This variety is naturally found from the Eastern Himalayas to China (from Southern Yunnan to Southern Guangdong) and Northern Indo-China. It typically grows as a shrub or tree, thriving primarily in the wet tropical biome.

 

 

Genetic Populations of Assamica

  • India var. assamica (Assam, India)
  • Cambod type (Indochina)
  • China var. assamica (Southwest Yunnan)
  • Jingping, Honghe district, Yunnan
  • Malipo, Wenshan district, Yunnan

 

Unique Traits of Assam Tea  

 

Building upon insights provided by Roopak Goswami in his article on The Tea Biz Podcast and Blog site, scientists from China, the USA, and India recently published their study in the Journal of Plant Beverage Research. They have identified: 

 

  • Genetic Architecture:  Assam tea possesses unique genetic architecture.
  • High Polyphenol Content: Notable for high polyphenol content and broad leaves.
  • Environmental Adaptation: Suited to hot and humid climates.

 

Origin and Dispersal

 

In his scientific paper, Dr. Gautam Kumar Saikia identified:

 

  • Probable Origin: Near the source of the Irrawaddy River.
  • Dispersal: Spread to southeast China, Indo-China, and Assam.
  • Indigenous Confirmation: Wild trees in Assam are indigenous.

Other Camellia Species

 

  • Limited Use: Species like Camellia taliensis and Camellia formosensis used for tea but less studied.
  • Research Studies: Chemical composition and antioxidant activity studied in these species.

 

Geological Context

 

  • Continental Drift: Wegener's theory confirmed by modern geology's plate tectonics.
  • India-Asia Collision: Subduction of Indian plate under Eurasian plate began 110 million years ago.
  • Continuous Existence: India has remained as land since ancient geological periods.

 

The geological context of tea's history provides additional layers to its narrative. Continental drift, a concept pioneered by Alfred Wegener and later confirmed by modern geology's plate tectonics, sheds light on the movement of Earth's landmasses over millions of years.

 

 

The collision between the Indian and Asian plates, which began approximately 110 million years ago, resulted in the subduction of the Indian plate under the Eurasian plate. This geological event, known as the India-Asia collision, has had profound effects on the landscape, shaping mountain ranges like the Himalayas and influencing regional climates.

 

 

Interestingly, amidst these tectonic movements, India has remained a landmass since ancient geological periods. This continuous existence as land may have played a role in shaping the distribution of tea plants and influencing the development of tea cultures in the region.

 

 

In summary, the legendary origins of tea are multifaceted, encompassing both historical records and mythical tales. From Emperor Shen Nung's serendipitous discovery to the mythical creation attributed to Daruma or Bodhidharma, tea's story is as rich and diverse as the brew itself. These narratives, whether rooted in history or mythology, add layers of intrigue to the ancient origins of tea, inviting us to explore its fascinating past.
