Contribute additional antioxidant activity.
Minor constituents studied for anti-inflammatory activity.
Anti-inflammatory iridoids contributing to the plant's traditional respiratory and anti-inflammatory use.
Mucilage gives the soothing demulcent action; saponins contribute to the traditional expectorant effect.

Safety, Cautions & Contraindications
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.
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).
Generally considered safe for short-term use. The tiny hairs on the leaves can cause irritation if tea is not properly filtered. No significant drug interactions documented. Not recommended during pregnancy or breastfeeding due to lack of safety data.
Duke (2002) rates mullein as ++ with clinical evidence (score 2) for its expectorant activity, consistent with Commission E approval for catarrh and inflammation of the respiratory tract. It functions as a demulcent and emollient for mucous membranes. Traditionally used for bronchitis, asthma, and earaches (oil infusion). Dose: 1.5–2 g dried flower or leaf as tea, three to four times daily. Duke notes an antiviral (antiherpetic) activity at the experimental level. The plant is generally well-tolerated with no known significant contraindications at therapeutic doses (Duke, 2002).

Botanical Description
Low, mat-forming, aromatic perennial subshrub with tiny, oval, strongly aromatic leaves on trailing, wiry, hairy stems that root as they spread. Small, pinkish-purple, two-lipped flowers are borne in dense whorled clusters at the stem tips.
Tall, stately biennial herb forming a low first-year rosette of large, soft, thick, densely woolly grey-green leaves; in the second year it sends up a single, tall, unbranched flowering spike densely packed with bright yellow, five-petalled flowers that open a few at a time.[1]
Habitat
Grows on dry, sunny heath, grassland, rocky ground and sandy soils; native to Europe and widely distributed across the northern temperate zone.
Grows on dry, sunny waste ground, roadsides, disturbed soil and rocky slopes; native to Europe, North Africa and Asia and widely naturalised in North America and elsewhere.[1]
Harvesting
The flowering aerial parts (flower and leaf) are cut at the start of flowering in summer and dried in a warm, shaded, airy place.
The flowers are picked individually as they open through summer (since they open only a few at a time and quickly fade once picked); leaves are gathered from the first-year rosette or second-year plant and dried, with care to filter out the fine leaf hairs, which can irritate the throat if not strained from tea.[1]
Traditional Uses
Great mullein has a long European and Native American tradition as a soothing demulcent and expectorant remedy for cough, bronchitis and irritated airways, and the flower has also been infused in oil as a traditional remedy for earache; the soft, woolly leaf gave rise to old names like 'flannel leaf' and 'velvet plant'.[1, 2]

Dosage
Not documented
The EU herbal monograph gives 1.5-2 g of the flower in 150 mL of boiling water as an infusion, three to four times daily (daily dose 4.5-8 g), in adolescents, adults and elderly; the infusion should be carefully strained to remove the irritant hairs. The monograph covers the FLOWER (Verbasci flos) only — it gives no posology for the leaf. Not recommended under 12 years. Educational reference only, not a prescription.
