Sage, Studies
Alzheimer's
- Sage (Salvia officinalis) extract has a therapeutic effect on patients with mild to moderate Alzheimer's disease.
- Salvia officinalis extract in the treatment of patients with mild to moderate Alzheimer's disease: a double blind, randomized and placebo-controlled study Alzheimer's disease is characterized by a slow, progressive decline in cognitive function and behaviour. Acetylcholine esterase inhibitors are the only agents approved by the Food and Drug Administration for the treatment of Alzheimer's disease. All other agents prescribed for the treatment of Alzheimer's disease are used on an off-label basis. Current research into new drugs is focused on agents that will prevent, slow down and/or halt the progress of the disease process. Salvia officinalis has been used in herbal medicine for many centuries. It has been suggested, on the basis of traditional medicine, its in vitro cholinergic binding properties and modulation of mood and cognitive performance in humans, that Salvia officinalis might potentially provide a novel natural treatment for Alzheimer's disease. The objective of this study was to assess the efficacy and safety of Salvia officinalis extract using a fixed dose (60 drops/day), in patients with mild to moderate Alzheimer's disease, over a 4-month period.
Results:At 4 months, S. officinalis extract produced a significant better outcome on cognitive functions than placebo (ADAS-cog: F = 4.77, d.f. = 1, P = 0.03) (CDR-SB: F = 10.84, d.f. = 1, P < 0.003). There were no significant differences in the two groups in terms of observed side-effects except agitation that appears to be more frequent in the placebo group (P = 0.09).
Conclusions:The results of this study indicate the efficacy of S. officinalis extract in the management of mild to moderate Alzheimer's disease. Moreover, S. officinalis may well reduce agitation of patients but this needs to be confirmed.
