Chrysanthemum tea is a very popular drink in East Asia and is commonly drank in hot or cold form at places that serve 'yum cha' or in bottled/canned/packed varieties from convenience stores.
Traditionally speaking, chrysanthemum is a highly regarded herb cultivated by ancient Chinese nobility and has been used in Chinese medicine for centuries in the treatment of influenza like symptoms, heatstroke and sore throats. In western herbal medicine, the tea has been used to treat disorders such as varicose veins and atherosclerosis.
The common chrysanthemum tea that you can buy in bottles these days typically contains water, cane sugar and brewed white chrysanthemum and depending on the brand, white tea as well. White tea, which comes from the same tea plant species as Green Tea possesses a similar taste profile and the natural goodness that is found in tea leaves.
Two brands that I've come across which are particular soothing to drink are Pokka (Japanese brand) and Yeo's (Singapore). I like the fact that they're not too sweet with the aroma and taste of chrysanthemum just right.
