Kakkonto (葛根湯, Mandarin Chinese: gěgēntāng, Japanese: kakkontō) is an herbal drink with its origin in traditional Chinese medicine. It is made from a mixture of ginger, cinnamon, Chinese peony, licorice, jujube, ephedra, and powder ground from the root of the kudzu plant, one of the 50 fundamental herbs. As the name, which translates literally to "kudzu infusion", implies, kudzu, or pueraria lobata, serves as the main ingredient. Together these plants are used to create a drink rich in puerarin, daidzein, paenoflorin, cinnamic acid, glycyrrhizin, ephedrine and gingerol.[1] The main active components are indexed as ephedrine and pseudoephedrine.[2] The resulting tea is used as a home remedy for fevers, headaches and hangovers.


Medical Studies[edit]

One study concluded, "Pueraria lobata appears to be an inappropriate herb for use in herbal hangover remedies as it is an inhibitor of ALDH2."[3] 15–30 minutes after taking kakkonto, the drinker shows increased sympathetic nerve function, and it may be this period that fulfills the important role in the treatment of cold syndromes.[4] Another study showed that kakkonto may have a positive effect on some respiratory infections.[5] Another study found that it relieved food allergy-related gastrointestinal symptoms in mice.[6]
