Sage
Sage is a Mediterranean herb (Salvia officinalis) rich in polyphenols and volatile oils, commonly used as a culinary seasoning and traditional remedy with antioxidant properties. Some laboratory studies suggest antimicrobial activity, though evidence in humans is limited.

Sage is a perennial herb native to the Mediterranean region, belonging to the mint family (Lamiaceae). It is widely available fresh, dried, or as an extract, and used in cooking to flavor poultry, pasta, soups, and savory dishes. The dried leaf is the most common form in commerce. Sage has been used in traditional medicine systems for centuries, though modern evidence is limited to modest in vitro and animal studies.
Sage leaves contain phenolic compounds including rosmarinic acid and carnosic acid, along with volatile essential oils such as thujone, eucalyptol, camphene, and camphor. These constituents exhibit antioxidant activity in laboratory conditions. Sage is low in calories and macronutrients when used in typical culinary amounts (1–2 grams per serving). The herb does not significantly alter digestion or gut bacteria at standard culinary doses, though concentrated extracts have not been extensively studied in human populations.
Cognitive and Memory Function
Several small human trials have examined sage extract effects on cognition, with mixed results. A systematic review of available evidence found modest short-term improvements in memory and attention in healthy adults taking sage extract, but sample sizes were small and effect sizes modest. These studies used concentrated extracts (300–600 mg), far exceeding typical culinary consumption. The evidence does not support using culinary sage as a treatment for cognitive decline or neurological conditions.
Safety, Tolerability, and Portion Guidance
Sage is safe for most people at ordinary culinary doses (dried leaf 1–2 grams per meal). Thujone, a neurotoxic component of sage essential oil, is present in low levels in dried leaf and negligible in most commercial products. Pregnant and breastfeeding individuals should avoid high-dose sage extracts. Some authoritative sources advise avoiding sage during pregnancy due to its potential as a uterine stimulant. For breastfeeding individuals, sage may reduce milk supply. Pregnant and breastfeeding individuals should consult a healthcare provider before using sage, including in culinary amounts. Individuals taking anticoagulants or with a personal or family history of estrogen-sensitive cancers should consult a healthcare provider before using sage supplements, as some in vitro evidence suggests weak estrogenic activity. Allergic reactions are rare but possible in individuals with sensitivity to other mint family herbs.
Frequently Asked Questions
Is sage safe to use every day in cooking?
Yes. Sage in typical culinary amounts (1–2 grams of dried leaf per serving) is safe for regular use in healthy adults. At these doses, thujone and other compounds are present in trace amounts. High-dose sage extracts or essential oils should not be consumed regularly without medical guidance.
Does sage improve memory or cognitive function?
Small clinical trials suggest sage extract may produce modest, short-term improvements in memory and attention in healthy adults, but effect sizes are small and evidence is limited. These studies used concentrated extracts (300–600 mg), not culinary amounts. Sage is not established as a treatment for memory loss or neurological disorders.
Can sage be used during pregnancy or breastfeeding?
Pregnant and breastfeeding individuals should exercise caution with sage. Some authoritative sources advise avoiding sage during pregnancy due to its potential as a uterine stimulant. For breastfeeding individuals, sage may reduce milk supply. High-dose sage extracts or essential oils should be avoided. Pregnant and breastfeeding individuals should consult their healthcare provider before using sage, even in culinary amounts.
