Why in news?
The Food Safety and Standards Authority of India (FSSAI) issued a directive on December 24-26, 2025, stating that only beverages derived from the Camellia sinensis plant can be labeled as "tea." This targets misleading labels like "herbal tea," "rooibos tea," and "flower tea," which do not originate from this plant and violate the Food Safety and Standards Act, 2006.​
Camellia sinensis is the evergreen shrub whose leaves and buds are used to make all traditional teas—green, black, oolong, white, and more. It belongs to the family Theaceae and is cultivated widely across Asia and beyond.

All major teas come from Camellia sinensis, with differences arising from processing methods:
