Where Does Sage Have the Strongest Evidence?

Sage has been investigated in several human clinical studies, but the strength of evidence differs considerably between uses.

One of the most promising areas is menopausal symptoms. In a randomized placebo-controlled trial, a standardized fresh sage extract reduced overall menopausal symptoms and particularly hot flushes. Improvements were also reported in areas such as sleep and fatigue.

Sage preparations have also been studied for oral health. In a small controlled study, a sage gel used alongside standard periodontal treatment reduced gum bleeding and improved some measures of periodontal health.

Another interesting research area is cognitive performance and memory. A clinical study using a preparation containing Salvia officinalis polyphenols together with compounds from another sage species reported improvements in several memory-related tasks. However, because this was a mixed-sage formulation, the results cannot be attributed to Salvia officinalis alone.

Sage essential oil has also been tested in aromatherapy studies, including research involving women’s sexual health. Some studies reported positive effects, while others found no clear advantage. Overall, the clinical evidence for sage essential oil is more variable than that for standardized sage extracts.
