Planetary Herbals Kudzu Recovery™ features the roots of kudzu (Pueraria lobate), which have long been used in Chinese herbalism to help lessen the desire for alcohol. Researchers have identified two constituents in kudzu responsible for this activity, daidzein and daidzin, which in animal research have been found to cause a similar effect. These are combined with coptis, a primary cleansing and liver-supporting herb from Chinese herbalism, and other key botanicals historically used to reduce cravings.
