Benefit Evidence
Research sources
Blood circulation (1)
- [Clinical study on treatment of carotid atherosclerosis with extraction of polygoni cuspidati rhizoma et radix and crataegi fructus: a randomized controlled trial]
PubMed ID: 24956862
Six-month RCT (P. cuspidatum + hawthorn) showed reduced carotid IMT and plaque measures, indicating improved vascular markers, though effect cannot be isolated to P. cuspidatum.
Heart health (1)
- [Clinical study on treatment of carotid atherosclerosis with extraction of polygoni cuspidati rhizoma et radix and crataegi fructus: a randomized controlled trial]
PubMed ID: 24956862
Combination product reduced carotid IMT and plaque integral over six months, which is relevant to cardiovascular health though causality to P. cuspidatum alone is uncertain.
Inflammation (1)
- [Clinical study on treatment of carotid atherosclerosis with extraction of polygoni cuspidati rhizoma et radix and crataegi fructus: a randomized controlled trial]
PubMed ID: 24956862
Combination intervention produced greater hs-CRP reductions vs control; supports anti-inflammatory potential though not P. cuspidatum-specific.
Nutrition source (1)
- [Clinical study on treatment of carotid atherosclerosis with extraction of polygoni cuspidati rhizoma et radix and crataegi fructus: a randomized controlled trial]
PubMed ID: 24956862
Trial included P. cuspidatum in a combination product; shows clinical use of P. cuspidatum as a resveratrol-containing ingredient, but effects confounded by co-ingredient (hawthorn).
