Studies
• Studies have shown sage slows down the release of
enzymes that break down the neurotransmitter, acetylcholie; and inhibition
of this enzyme can improve mood with maintaining optimal levels of acetylcholine.
A study using 300 to 600 mg of sage leaf extract showed some benefit
in alertness and calmness. An alternative to the capsules, a decoction
of tsp dried sage in 1 cup of water (Do not use if pregnant).
• Alzheimer's Disease:
A study of SO extract in patients with mild to moderate Alzheimer's
disease showed significant benefits in cognition possibly through cholinesterase
inhibition. Mild agitation side effects noted in the placebo group may
suggest an additional advantage for use in patients with Alzheimer's
disease.
• Antibacterial:
Study of Salvia officinalis essential oil and its fractions showed significant
antibacterial effect against S aureus and B subtilis.
• Acute Pharyngitis:
Study showed a 15% sage spray to be a safe and convenient treatment
for patients with acute pharyngitis, with a relief superior to placebo.
• Cholinesterase Inhibiting Property:
Study confirms the cholinesterase inhibiting property of S officinalis
and improved mood and cognitive performance following single-dose use
in healthy young participants.
• Antioxidant: Tunisian
study of oils produced from the aerial parts of SO showed it to possess
strong antioxidant properties.
• Liver antioxidant:
An inv-vivo study of a traditional sage water infusion in mice and rats
dhoerf bioactivities and improvement in liver antioxidant potential.
• Antimutagenic:
Study demonstrated the antimutagenic activity of volatile sage terpenes,
suggesting further antimutagenesis and anticarcinogenesis studies.
• Metformin-like effect:
Study effects on fasting glucose and its metformin-like effects on rat
hepatocyctes suggest sage may be a useful food supplement for T2D.
