Rating (out of 5): 1

Kudzu (Pueraria lobata) has a long history of use in traditional Chinese medicine, where it is known as "ge gen." While kudzu is primarily used for treating conditions such as alcoholism, fever, and cardiovascular issues, there are some anecdotal reports and minor traditional references to its calming effects, which may indirectly relate to insomnia or trouble sleeping. However, these references are sparse, and kudzu is not a primary herbal remedy for insomnia in Chinese or other traditional medicine systems. Scientifically, there is insufficient evidence to support the use of kudzu for insomnia. Most modern research on kudzu has focused on its potential effects on alcohol metabolism, cardiovascular health, and menopausal symptoms. There are a few animal studies suggesting that some isoflavones found in kudzu may have anxiolytic (anti-anxiety) or sedative effects, but these findings have not been robustly replicated in human clinical trials for sleep disorders. In summary, the use of kudzu for insomnia is grounded more in tradition and anecdote than in strong scientific evidence. If used, it is typically as part of a larger formula rather than as a primary agent for sleep. People interested in herbal approaches to insomnia may find better support for ingredients such as valerian root, passionflower, or chamomile.
