India, Dec. 31 -- Winter often brings a rise in colds, coughs, sore throats, and viral infections, making warming immunity blends a practical addition to daily routines. These blends are prepared by steeping spices, herbs, seeds, or roots in hot water and are commonly consumed during colder months to support immune function, digestion, and respiratory comfort.

Unlike regular tea, many of these drinks are classified as herbal infusions. According to FSSAI guidelines, only beverages made from Camellia sinensis qualify as tea, while immunity-focused spice and herb blends fall under the category of herbal infusions. This distinction is essential, as the benefits come from functional ingredients rather than tea leaves.
