Salvia (Sage) comes from the Latin word meaning ‘to heal.’ There are over 900 species of Salvia throughout the world, the most popular being Salvia officinalis L. Research has demonstrated its ability to enhance mental performance, cognition, and memory [1].
Salvia officinalis L., also known as Common Sage, is regarded as the queen of
Sage contains a large number of phytochemicals which have a vast array of biological activities, many of them relevant to disorders of the central nervous system. In particular, Sage has:
A list of some of the major components contained in Sage, along with their biological activities (as demonstrated in in vitro and in vivo studies) are detailed in the image at the bottom of this article.
In a paper I published in 2017, I summarised some of the studies investigating the therapeutic effects of sage [1]. There are several human-based studies that confirm sage has positive effects on mental performance, memory, mood, and attention. In addition to these studies, Sage has also been shown to effectively reduce menopausal symptoms such as hot flushes [2]; lower cholesterol and triglyceride levels in adults with high cholesterol [3]; reduce blood sugar and cholesterol levels in adults with diabetes [4]; and reduce hot flushes in men undergoing treatment for prostate cancer [5].
The exact mechanisms behind Sage’s neuroprotective, neuro-enhancing, and mood-lifting effects are not yet known. As Sage contains dozens of constituents, it probably has multiple beneficial effects on several biological systems. A summary of how Sage works is demonstrated in the image at the bottom of this article.
Studies investigating the brain-protective effects of Sage have indicated that an
The safety of Sage ingestion during pregnancy has not been investigated so is not recommended for pregnant women. Caution is also warranted for people on blood pressure medications.
