Sage (Salvia officinalis) has a long history of use in traditional herbal medicine, particularly in Europe and the Mediterranean, where it has been valued for a wide range of purposes, including supporting general vitality and energy. Traditional herbalists often recommended sage to help with feelings of weakness, fatigue, or low energy, sometimes attributing these effects to its warming and stimulating properties. Sage was also used in tonics and teas thought to invigorate the body and improve mood. However, while there is some modern scientific research on sage’s cognitive-enhancing properties—such as improved memory and attention—direct evidence for its use to specifically increase physical energy or combat fatigue is limited. Most scientific studies have focused on sage’s antioxidant, anti-inflammatory, and cognitive effects, rather than its impact on energy levels. Anecdotal and historical reports suggest that sage tea or extracts can make people feel refreshed or revitalized, but these claims have not been robustly validated in clinical trials. In summary, the use of sage for increasing energy is primarily based on traditional herbal practices rather than scientific validation. The quality of evidence supporting this use is therefore considered weak (rated 1/5), relying mostly on historical usage and anecdotal reports rather than rigorous scientific data.
