Frequently Asked Questions
What is Japanese Arrowroot (Kudzu)?
Japanese Arrowroot, or Kudzu (Pueraria montana var. lobata), is a perennial vine native to East Asia whose starchy tuberous roots have been used for centuries in Traditional Chinese Medicine and Japanese cuisine. Its primary bioactive compound, puerarin, is an isoflavone with documented antioxidant, anti-inflammatory, and vasodilatory properties.
Is Japanese Arrowroot safe and what is the recommended dosage?
At standard dosages of 500-1000 mg of standardized extract daily, kudzu root is generally well tolerated. However, it may interact with blood thinners, diabetes medications, and hormone-sensitive conditions due to its isoflavone content. Consult a healthcare provider before use if you take prescription medications.
Can Japanese Arrowroot really help with alcohol cravings?
Several human clinical studies, including research from Harvard Medical School, have shown that kudzu root extract may reduce binge drinking and alcohol consumption. The mechanism appears to involve increased blood flow to the brain and modulation of alcohol metabolism, though it is not a standalone treatment for alcohol use disorder.
