Tea is an aromatic beverage made by pouring hot or boiling water over cured leaves of the Camillia Sinensis, an evergreen shrub native to Asia. Other than water, it is the most widely-drunk beverage in the world. Teas can be made by infusing boiling water on any plant. Technically these are tisanes or herbal infusions to prevent confusion with tea made from the tea plant.
International Tea Day has been observed annually on December 15 since 2005 in tea-producing countries like Bangladesh, Sri Lanka, Uganda, India, and Tanzania. International Tea Day aims to draw global attention to the impact of the global tea trade on workers and growers, and has been linked to requests for price supports and fair trade.
In 2015, the Indian government proposed expanding the observance of International Tea Day through the United National Food and Agriculture Organization.
