What is Tibetan pearl fragrance?

Red wormwood atractylodes rhizome incense is a bamboo stick incense made of Chinese herbal medicines such as red wormwood, atractylodes rhizome and fragrant leaves by traditional technology.

Atractylodes lancea is a traditional Chinese medicine. In our hometown, most people collect some. It's not a cure, it's a smoke room at noon on the Dragon Boat Festival. I wonder if this custom can be found anywhere else.
