Tea is a versatile ingredient. It can be a drink, food, and “a material of aroma”.
The picture shows a tea incense burner called Cha-Koro.
This is more than just creating fragrance. Since tea has disinfectant and deodorant effects, lighting “tea incense” helps remove odor for rooms, too.
Even infused tea leaves can also make good odor-removers for refrigerators and wardrobes. In this case, dry the leaves thoroughly and wrap them in a gauze bag. Don’t forget to take them out periodically and re-dry them, or replace them with another.
Tea is tea. But, it takes on multiple roles!
