Parts: Flower, Leaf
Season: Summer, at start of flowering

Key Constituents

Essential oil (thymol, carvacrol, p-cymene)[2]

The volatile oil, dominated by thymol and carvacrol, gives most of the antimicrobial and antioxidant activity.

Traditional Use & History

Wild thyme has a long European folk tradition, closely paralleling its relative garden thyme, as an antimicrobial and expectorant remedy for coughs and respiratory infections, a digestive/gastroprotective herb, and a topical antiseptic.[12, 13, 14]

Preparations

Infusion[13]

Dried flowering herb infused in hot water as a traditional respiratory and digestive tea.

Safety, Cautions & Contraindications

Safety note[12, 13, 14]Caution

Generally safe at culinary doses. Essential oil is highly concentrated and must be diluted before topical use; undiluted application can cause skin sensitisation. Not recommended internally during pregnancy (uterine stimulant effects possible). Phenol-rich thyme preparations should be avoided long-term in high doses. May potentiate anticoagulant medications.

Safety note[12, 13, 14, 15]Info

Duke (2002) rates Thymus vulgaris (garden thyme, closely related to breckland thyme) as +++ with clinical evidence (score 2) for antibacterial, bronchospasmolytic, and antispasmodic activities, consistent with Commission E and WHO approvals for bronchitis and upper respiratory catarrh. The primary active constituent is thymol, with carvacrol as a secondary compound. Dose: 1–2 g dried herb as tea three times daily. The plant demonstrates COX-2 inhibitory activity and calcium antagonism, which may explain its antispasmodic effects (Duke, 2002).

Harvest Readiness

[11]

Part: flower
Signals: Cut the flowering tops as the plant comes into flower, in summer.
Basis: traditional
Source Quote: can be harvested as it comes into flower and either be distilled for the oil or dried for later use
Species Confirmed: 1
Notes: PFAF (REF-3349); the flowering tops are cut as the plant comes into flower (in flower July-August). Single lineage -> provisional.

[11]

Part: leaf
Signals: Gather the leaves just before the flowers open (early and late summer), when the aromatic oil is highest.
Basis: traditional
Source Quote: If the leaves are to be dried, the plants should be harvested in early and late summer just before the flowers open
Species Confirmed: 1
Notes: PFAF (REF-3349); the leaves are gathered just before the flowers open (early and late summer), when the oil is highest. Single lineage -> provisional.
