Have you tried “Wong Lo Kat” Herbal Drink in can? I have tried it numerous times and found it quite soothing. Unlike the traditional herbal drink, “Wong Lo Kat” is sweetened even though it says no preservatives on the can.

The writings on the can says:
The origin of Chinese Herbal Drink dating from the Qing Dynasty, made from selected herbal ingredients using advanced scientific technique based on traditional recipe.
