Pharmacological Actions
Traditional & Indicated Uses
Memory and cognitive-function support (enhances cognition in healthy subjects and people with dementia)
Reduces excessive sweating, including menopausal hot flushes and night sweats
Carminative for mild dyspeptic complaints (indigestion)
Gargle/rinse for sore throat and inflammation of the mouth and throat
Memory and cognitive-function support (enhances cognition in healthy subjects and people with dementia)
Gargle/rinse for sore throat and inflammation of the mouth and throat
Expectorant for productive (chesty) cough associated with cold and bronchitis - a fixed thyme-ivy extract combination outperformed placebo in acute bronchitis (faster, greater reduction in coughing fits)
inferred from anticancer action
Expectorant for productive (chesty) cough associated with cold and bronchitis - a fixed thyme-ivy extract combination outperformed placebo in acute bronchitis (faster, greater reduction in coughing fits)
Expectorant for productive (chesty) cough associated with cold and bronchitis - a fixed thyme-ivy extract combination outperformed placebo in acute bronchitis (faster, greater reduction in coughing fits)
Antimicrobial (thymol and carvacrol) - supports respiratory infection
inferred from antispasmodic action
inferred from expectorant action
Sore throat relief (antiseptic gargle)
Safety, Cautions & Contraindications
The essential oil contains thujone, which is neurotoxic and can trigger seizures in high doses - do not exceed recommended doses and do not take the pure essential oil internally; avoid medicinal doses in epilepsy.
Avoid medicinal and essential-oil doses in pregnancy and breastfeeding (thujone; sage may also reduce milk supply). Culinary amounts are safe.
Culinary amounts are safe. Thyme essential oil is a strong irritant - dilute well before any topical use and do not take the undiluted oil internally.
A cough that persists beyond about a week, or with fever or breathlessness, needs medical assessment. Avoid medicinal/oil doses in pregnancy; allergy is possible in people sensitive to the mint family (Lamiaceae).

Botanical Description
Evergreen, woody-based perennial subshrub (Lamiaceae), 30-70 cm tall, with square, downy, greyish stems. Leaves are opposite, oblong, wrinkled, grey-green and softly velvety, with a strong camphoraceous aroma. Violet-blue, two-lipped flowers are borne in whorled spikes.[11]
Low, woody-based aromatic perennial subshrub with small, narrow, grey-green leaves and small, pale pink to lilac, two-lipped flowers borne in whorled clusters along the upper stems.[11]
Habitat
Native to the northern Mediterranean coast (particularly the Balkans and Italy), widely cultivated as a culinary and medicinal herb in gardens worldwide, preferring sunny, well-drained, often calcareous soils.[11]
Grows on dry, sunny, rocky, well-drained soils; native to the western Mediterranean and widely cultivated as a culinary and medicinal herb worldwide.[11]
Harvesting
Leaves are harvested throughout the growing season, ideally just before flowering, when essential-oil content is highest, and dried quickly in a warm, shaded place.[11]
The flowering aerial parts are cut just as flowering begins, when essential oil content is highest, and dried in a warm, shaded, airy place; essential oil is obtained by steam distillation of the fresh or dried herb.[11]
Traditional Uses
Sage has an ancient reputation - its Latin name 'salvia' derives from 'salvere', to be saved or healed - as a digestive, antiseptic and cognitive tonic. It has official European herbal-monograph use for dyspeptic complaints and excessive sweating, and as a gargle for inflammation of the mouth and throat; modern clinical trials support cognitive-enhancing effects in both healthy adults and people with dementia.[11, 12]
Thyme has a long Mediterranean and European tradition as an antimicrobial and expectorant remedy for coughs, bronchitis and sore throat, formalised in EU herbal monograph recognition, with a fixed thyme-ivy extract combination shown superior to placebo for acute bronchitis with productive cough in clinical trial.[11, 13]
Preparations
Dried herb infused in hot water as a traditional cough, cold and digestive tea.
Infusion used as a gargle for sore throat, drawing on the antiseptic essential oil constituents.
Standardized fluid extract, often combined with ivy leaf, the form studied in clinical trials for acute bronchitis.
Dosage
EMA herbal-monograph guidance suggests about 1-3 g dried leaf per cup as an infusion, up to three times daily for digestive complaints, or a stronger preparation used as a gargle. Avoid prolonged or high-dose (essential-oil) use given the neurotoxic thujone content, especially in pregnancy and epilepsy. Educational reference only, not a prescription.
The EU herbal monograph suggests around 1-2 g of dried herb per cup, up to three times daily. Educational reference only, not a prescription; do not take the essential oil undiluted internally.
