What Sage Is Used For

  • Historically, sage was used as a fertility drug in ancient Egypt. Physicians in ancient Greece used a solution of sage and water to stop wounds from bleeding and to clean sores and ulcers.
  • Today, sage is used for mouth and throat inflammation, indigestion, and excessive sweating. Sage is also used as an ingredient in some dietary supplements for mouth, throat, and gastrointestinal problems.
  • Some people may use sage to improve mood, or boost memory or mental performance.

 

How Sage Is Used

Sage is available as dried leaves, liquid extracts and sprays, and essential oils.

 

What the Science Says

  • Sage has not been well studied as a treatment for sore throat, so there is little scientific evidence to support its use for that ailment.
  • Two small studies suggest that sage may improve mood and mental performance in healthy young people and memory and attention in older adults. Results of another small clinical study suggest that a sage extract was better than placebo at enhancing thinking and learning in older adults with mild to moderate Alzheimer's disease.
  • Laboratory studies suggest that essential oils from sage may have antimicrobial properties.

 

Side Effects and Cautions

  • Sage is generally regarded as safe by the U.S. Food and Drug Administration and is approved for food use as a spice or seasoning. However, some species of sage contain thujone, which can affect the nervous system. Extended use or taking large amounts of sage leaf or oil may result in restlessness, vomiting, vertigo, rapid heart rate, tremors, seizures, and kidney damage. It also may lead to wheezing. Ingesting 12 drops or more of the essential oil is considered a toxic dose.
  • Drug interactions with sage have not been thoroughly studied.
  • Sage can stimulate allergic or hypersensitivity reactions. Skin contact may result in inflammation. Ingesting sage powder or dust may cause breathing difficulties.
  • Tell all your health care providers about any complementary and alternative practices you use. Give them a full picture of what you do to manage your health. This will help ensure coordinated and safe care. For tips about talking with your health care providers about CAM, see NCCAM's Time to Talk campaign.
