Key Findings:
- The oxaliplatin plus TM groups showed significantly reduced CINV (risk ratio 0.65 [0.59, 0.71], I(2) = 28%) compared with oxaliplatin controls, with or without the addition of conventional anti-emetics.
- These plants warrant further clinical research as potential additions to chemotherapy regimens in patients whose CINV is not sufficiently well controlled by conventional therapies.

“DSs marketed in Italy are usually blends of many substances that are frequently employed at a negligible dose or without any evidence.”
Key Findings:
- Based on the scoring system, 2 (8%) supplements matched with the cluster of higher expected efficacy, 3 (12%) with the lower efficacy cluster and 20 (80%) matched with the criterion of no expected efficacy.
- A systematic review of the literature was performed to evaluate the effect of DS and to detect the active ingredients able to improve erectile function-called effective ingredients (EIs)-and their minimal effective daily dose (mED).
- A metanalysis identified some nutraceuticals, such as Panax ginseng, Tribulus terrestris and L-arginine, that are able to improve male sexual function.
- DSs marketed in Italy are usually blends of many substances that are frequently employed at a negligible dose or without any evidence.

“This systematic review suggests that the ingestion of PGPs or ginsenosides, especially Rg1, is effective in improving exercise endurance in healthy adults.”
Key Findings:
- We found that ingestion of PGPs or ginsenosides significantly improved exercise endurance (SMD [95% CI]: 0.58 [0.22-0.95], I2 = 0%).
- It was suggested that ginsenoside Rg1 (Rg1) and PGPs extract containing Rg1 were significantly effective in improving exercise endurance (SMD [95% CI]: 0.70 [0.14-1.27], I2 = 30%) by additional analysis.
- This systematic review suggests that the ingestion of PGPs or ginsenosides, especially Rg1, is effective in improving exercise endurance in healthy adults.
- However, further high-quality randomized controlled trials are required because imprecision and publication bias cannot be ignored in this systematic review.

“Only a few studies have been specifically designed to assess how herbal preparations affect MGBA-related targets or pathways.”
Key Findings:
- Only a few studies have been specifically designed to assess how herbal preparations affect MGBA-related targets or pathways.
- However, many studies provide hints of a possible interaction with the MGBA, such as an increased abundance of health-beneficial microorganisms, anti-inflammatory effects, or MGBA-related pathway effects by gut microbial metabolites.
- Data for Panax ginseng, Schisandra chinensis, and Salvia rosmarinus indicate that the interaction of their constituents with the gut microbiota could mediate mental health benefits.
- Studies specifically assessing the effects on MGBA-related pathways are still required for most medicinal plants.

“In the future, there is great potential to register medicinal products that contain plant adaptogens for therapeutic purposes.”
Key Findings:
- About 50 years ago, plant adaptogens were first used in professional sports due to their high potential to increase the body's resistance to stress and to improve physical endurance.
- Although now many people take plant adaptogens, the clinical trials on human are limited.
- The data from the meta-analysis showed that plant adaptogens could provide a number of benefits in the treatment of chronic fatigue, cognitive impairment, and immune protection.
- In the future, there is great potential to register medicinal products that contain plant adaptogens for therapeutic purposes.
