Sage has been traditionally used to create brain-enhancing tonics, with studies demonstrating its ability to enhance cognitive function and protect against neurological diseases1. Research has found that sage extract can improve memory and mood, with active compounds like rosmarinic acid and luteolin providing neuroprotective properties4. The herb's combination of phenolic acids protects the brain from stress-induced damage and fights free radicals that cause inflammation, thereby reducing dementia risk1. Salvia officinalis has been shown to help stall dementia progression, while the herb's natural antidepressant properties prove valuable for treating late-stage dementia agitation1.
Red sage (Salvia miltiorrhiza), known in Traditional Chinese Medicine as Dan Shen, demonstrates remarkable heart-normalizing actions3. Clinical testing on angina showed close to 90% of patients were significantly helped, while approximately 80% of arrhythmias were corrected or improved3. Dan Shen has been observed to help correct mitral valve problems over long-term use and can thin the blood without the toxicity associated with pharmaceutical blood thinners like Coumadin3. The herb is also effective for unhealthy blood cholesterol and dissolving clots3.
Red sage has been scientifically validated for treating acute kidney injury. Research published in The American Journal of Chinese Medicine demonstrated that tanshinone IIA, an active component of red sage, improved kidney function in animal models by reducing renal tubular epithelial injury and decreasing inflammatory cell infiltration2. Additional studies showed red sage treatment significantly restored abnormal kidney function in iron-overloaded mice, reducing oxidative stress markers like blood urea nitrogen and creatinine while increasing antioxidant enzyme activities2.
Wild clary (Salvia verbenaca) has been shown to protect red blood cells from damage. Research published in the African Journal of Traditional, Complementary and Alternative Medicines demonstrated that wild clary extract possesses antihemolytic, antioxidant, and antibacterial activities5. The extract successfully prevented red blood cell damage from free radicals and inhibited the production of excess uric acid, which can cause painful gout conditions5. The extract also demonstrated effectiveness against pathogenic bacteria including E. coli, Staphylococcus aureus, and Salmonella typhi5.
