How Does Sage Enhance Memory?

Sage enhances memory by modulating key neurotransmitters and protecting brain cells from oxidative damage.

A randomized, double-blind, placebo-controlled trial found that a proprietary sage extract improved both immediate and delayed word recall in healthy older adults.(1)

Sage inhibits acetylcholinesterase, the enzyme that breaks down acetylcholine, thereby increasing levels of this memory-boosting neurotransmitter in the brain.

Sage also prevents the formation of amyloid-beta plaques that are implicated in age-related memory loss and Alzheimer’s disease.

How Does Sage Improve Attention Span and Focus?

Sage improves attention span and focus by optimizing brain neurochemistry and increasing cerebral blood flow.

In a clinical study from 2005, a single dose of sage extract enhanced accuracy of attention and secondary memory performance in healthy adults.(2)

The aromatic compounds in sage inhibit GABA transaminase, an enzyme that degrades GABA, leading to higher levels of this calming neurotransmitter which promotes relaxed concentration.

Sage also boosts cerebral circulation, delivering more oxygen and nutrients to the brain to support peak cognitive function.

How Does Sage Increase Mental Stamina?

Sage increases mental stamina by fighting fatigue, sharpening focus, and strengthening overall cognitive function.

Research from 2006, demonstrated that sage extract improved cognitive performance and increased alertness in a mental arithmetic task.(3)

The antioxidant compounds in sage, such as rosmarinic acid and carnosic acid, protect brain cells from the damaging effects of free radicals, which can deplete mental energy.

By enhancing cerebral blood flow, sage also delivers more energizing oxygen and glucose to the brain to support sustained mental performance.

How Does Sage Prevent and Reduce Cognitive Decline?

Sage prevents and reduces cognitive decline by shielding neurons from damage, inflammation, and age-related changes.

A review from 2017 concluded that sage has significant neuroprotective properties relevant for preventing Alzheimer’s disease and age-related cognitive impairment.(4)

Sage inhibits the formation of destructive amyloid-beta plaques and tau proteins that accumulate in the aging brain and interfere with neuronal communication.

The potent anti-inflammatory and antioxidant compounds in sage, like rosmarinic acid and carnosol, also defend brain cells from chronic low-grade inflammation and oxidative stress that contribute to cognitive decline.

How Does Sage Reduce Anxiety?

Sage reduces anxiety by modulating neurotransmitters and stress hormones to promote calmness and positive mood.

An open-label study from 2011 found that a proprietary sage extract decreased anxiety scores by 18% in adults with mild to moderate anxiety.(5)

Sage contains flavonoids and polyphenols that interact with GABA receptors to increase the calming effects of this inhibitory neurotransmitter, reducing anxiety and restlessness.

Sage also lowers cortisol, the primary stress hormone, and may boost serotonin levels to further relieve anxiety and improve emotional well-being.

What Are The Potential Side Effects and Risks of Sage?

Sage is generally well-tolerated when used in recommended doses. However, some potential side effects may include:

  • Digestive discomfort (e.g., nausea, diarrhea)
  • Dry mouth
  • Dizziness or lightheadedness
  • Headache
  • Allergic reactions (rare)

High doses of sage, particularly essential oils, may cause toxicity due to the presence of thujone.

Warning: Prolonged use of high doses may lead to seizures, kidney damage, or other adverse effects.

Who Should Avoid Sage?

Certain individuals should avoid using sage or consult a healthcare professional before use:

  • Pregnant or breastfeeding women
  • People with seizure disorders
  • Individuals with kidney disease
  • Those allergic to plants in the Lamiaceae family (e.g., mint, basil, lavender)

Does Sage Interact With Any Medications?

Sage may interact with certain medications, including:

  • Anticonvulsants: Sage may lower the seizure threshold and reduce the effectiveness of anticonvulsant drugs.
  • Diabetes medications: Sage may lower blood sugar levels and potentially enhance the effects of diabetes medications.
  • Sedatives: Sage may have additive effects when combined with sedative medications, increasing the risk of drowsiness and impaired cognitive function.

Always consult a healthcare professional before combining sage with any medications.
