The short answer. There isn't much data on Red Ginseng yet — 9 mentions, 3 with a clear outcome — so treat these numbers as anecdotal. It is well studied — 15 meta-analyses on PubMed.
From 9 mentions in total — the rest didn't say how it went and aren't counted.

Conclusion: Also, further research is required before definitive conclusions on efficacy and safety can be made. This systematic review was registered at PROSPERO as CRD42020173623.
PubMed 33150931 ↗Conclusion: Other pharmacological effects including estrogenic, enzymatic, anti-microorganism activities, and cardiovascular effects have been mentioned, but the results were considerably diverged. A higher quality of evidence on clinical trial studies is highly recommended to confirm the consistent efficacy of ginsenoside Rh1.
PubMed 29329463 ↗Conclusion: This systematic review provides positive evidence for the efficacy of KRG on reducing blood pressure in patients with pre-hypertension and hypertension in acute and long-term. Future RCTs appear to be warranted.
PubMed 28707603 ↗Conclusion: The available evidence suggests that several products are capable of significantly improving some, but not all, of the symptoms related to alcohol hangover. Therefore, further research is necessary to develop clinically effective hangover treatments.
