Kudzu (Pueraria lobata)
Tier 2 — promising · Alcohol reduction · Cardiovascular
A traditional Chinese herb studied for reducing alcohol consumption. A Harvard pilot RCT found kudzu root extract significantly reduced the number of drinks consumed per session. Contains isoflavones that may interact with dopamine reward pathways. Only a small number of human trials have been completed. More research is needed.
Dose: 1,500–2,000 mg/day standardised extract (40% isoflavones); limited human evidence
