Sage extract and essential oil have been found to lower acetylcholinesterase levels in the brain, which may explain the plant’s ability to improve memory and reduce excessive sweating.
Those experiencing excessive sweating may benefit from drinking sage tea, prepared by boiling two tablespoons of dried sage in one liter of water for ten minutes, then allowing it to steep for another fifteen minutes. The tea should be consumed only after it has fully cooled.
Laboratory studies have also confirmed that sage has antimicrobial properties and contains antioxidants that protect cell walls from damage.
Sage can be combined with other medicinal plants to enhance its effects:
- Mixed with rosemary, it acts as a brain tonic.
- Combined with echinacea, it supports oral and throat health.
- Paired with St. John’s wort, it can help alleviate anxiety and improve mood.

Dr. John Heinermann notes that sage is beneficial for various types of itching, whether caused by allergies, nervous conditions, psoriasis, eczema, or poisoning.
A natural remedy involves soaking a handful of fresh, crushed sage leaves in 600 ml of boiled water for an hour. After straining, the liquid can be applied externally to itchy areas. While the skin is still damp, covering it with wholemeal flour (rather than white flour) and letting it dry for ten minutes can enhance the soothing effect.
Dr. Richard Whelan advises that anyone using sage for the first time should start with a small dose to observe any potential reactions. For tea, half a teaspoon of dried sage boiled for five minutes with one cup of water is recommended. For tinctures, 10–20 drops per day is considered a safe dosage.
Precautions and Contraindications
Sage is not recommended for pregnant or breastfeeding women, individuals with epilepsy, or those with nephritis. Diabetics using sage should closely monitor their blood sugar levels throughout treatment.
