Monitor blood glucose more frequently when starting or stopping Panax ginseng. Watch for hypoglycemia symptoms including dizziness, sweating, confusion, and shakiness. Discuss use with your diabetes care provider before adding ginseng to your regimen.
Why this interaction occurs
Panax ginseng contains ginsenosides that have demonstrated insulin-sensitizing and insulin-secretagogue effects in clinical trials. When combined with metformin, additive glucose-lowering effects may occur, particularly in patients with tightly controlled HbA1c, increasing hypoglycemia risk despite metformin's low standalone hypoglycemia risk.
Evidence
Evidence level: moderate.
