Key Constituents
Principal wound-healing and anti-inflammatory constituents of the flower.
Antioxidant flavonoids and carotenoids give the flower its orange-yellow colour and contribute to its antioxidant activity.
Minor aromatic and resinous constituents of the flower head.
The needle oil is dominated by monoterpene hydrocarbons, chiefly alpha-pinene, giving the characteristic resinous scent and much of its antimicrobial activity.
The resinous sap/pitch, traditionally used topically for wounds and skin complaints.
The needle is traditionally valued as a source of vitamin C, particularly in winter.
Pharmacological Actions
Calendula officinalis extracts show cytotoxic antitumor, pro-apoptotic and antimetastatic activity across many cancer cell lines and in animal models (preclinical).
Traditional & Indicated Uses
inferred from anti-inflammatory action
A Calendula officinalis (LACE) aqueous extract inhibits proliferation (70-100%) of leukemia, melanoma, breast, prostate, lung and colon cancer cell lines via G0/G1 arrest and caspase-3 apoptosis and inhibits melanoma growth in nude mice; a systematic review documents its cytotoxic and antimetastatic antitumour activity (preclinical).

Safety, Cautions & Contraindications
Generally very safe for topical use. May cause contact dermatitis in rare cases (Asteraceae family allergy). Internal use is safe in normal doses. Avoid during pregnancy at therapeutic doses (uterine stimulant potential). Generally safe during breastfeeding for topical use.
Duke (2002) rates calendula (Calendula officinalis) and notes anti-inflammatory, wound-healing (vulnerary), antifungal, and antispasmodic activities at experimental levels. Commission E (KOM) approves calendula flower for wound healing and anti-inflammatory uses, both topically and as a gargle. The plant contains flavonoids, triterpene saponins (oleanolic acid glycosides), and essential oils. Dose: 1–2 g dried flower as tea (for mouth rinse/gargle); or as cream/ointment containing 2–5% calendula extract for topical use. Duke notes that calendula is generally very well-tolerated, though Asteraceae sensitivity can occasionally cause allergic reactions (Duke, 2002).
Generally safe in normal amounts. Pine essential oil should not be ingested; topical use only in diluted form. May irritate airways in high concentrations. Allergic reactions to pine pollen and resin are common. Turpentine products are irritant and potentially toxic if ingested.
Duke (2002) rates Scotch pine as + and notes antiseptic, antibacterial (score 1), and bronchospasmolytic activities. Commission E (KOM) and PhEur (PIP) approve pine needle preparations for topical use in rheumatic and neuralgic conditions and for inhalations in upper respiratory catarrh. Duke cautions that pine needle oil should not be inhaled by patients with severe asthma, whooping cough, or laryngospasm. Pine bud preparations are traditionally used for bronchitis and sinus congestion. Dose: 100–200 mg essential oil in ointment or cream for topical use (Duke, 2002).

Botanical Description
Aromatic annual or short-lived perennial herb with soft, hairy, oblong leaves and branching, slightly sticky stems. The flower heads are bright orange to yellow, daisy-like, with numerous narrow ray florets surrounding a darker central disc, opening in sunlight and closing at dusk.[1]
Evergreen coniferous tree (Pinaceae), 15-35 m tall, with a long, straight trunk at maturity, distinctive orange-red flaking bark in the upper crown and grey-brown fissured bark at the base. Needles are blue-green, borne in pairs (fascicles of two) with a papery basal sheath. Small yellow male cones release pollen in spring; female cones are woody and mature over two years.[11]
Habitat
Widely cultivated as a garden and medicinal plant; believed native to southern Europe and the Mediterranean, now naturalised in gardens and waste ground worldwide.[1]
Native across northern and central Europe and Siberia - the most widely distributed pine species in the world - forming extensive boreal and montane forests on poor, sandy or peaty, acidic soils; a pioneer species tolerant of dry, nutrient-poor ground.[11]
Harvesting
The flower heads (or just the ray-floret petals) are picked by hand as they open, through the flowering season, and dried quickly in a warm, shaded, airy place to preserve colour and resin content.[1]
Young shoots ('candles') and needles are gathered in spring; bark is stripped from felled or cultivated trees; resin/sap is tapped from the trunk. Needle-bearing twigs can be cut for tea and for steam distillation of the essential oil year-round.[11]
Traditional Uses
Calendula flower is one of the most widely used topical wound-healing and skin-soothing herbs in Western herbal medicine, applied to cuts, grazes, minor burns and skin inflammation, and used internally as a gentle anti-inflammatory and antimicrobial remedy and as a gargle for mouth and throat irritation.[1]
Scots pine has a long northern European tradition as a source of resinous, aromatic preparations for respiratory complaints (coughs, bronchitis, catarrh) and topical rheumatic/muscular remedies, and pine-needle tea has traditionally been valued as a vitamin-C-rich winter tonic. Modern research on the needle essential oil supports antimicrobial, anti-inflammatory and expectorant activity.[11, 12]
Preparations
Dried petals infused in a carrier oil, used as a soothing base for topical creams and balms for skin healing.
Standardised flower extract formulated into a cream or ointment for topical wound and skin care; the best-studied modern form.
Dried flower infused in hot water, 1-2 g in 150 ml, used still warm as a mouth rinse or gargle 2-4 times daily. The EU herbal monograph's posology for this preparation is OROMUCOSAL only - it does not support taking the infusion internally. Educational reference only, not a prescription.
Fresh or dried young needles steeped in hot water - the traditional vitamin-C-rich tonic tea. Only use needles from a certainly identified pine, never yew (see dangerous look-alikes).
Steam-distilled from the needles; used diluted in ointments, chest rubs or steam inhalation for respiratory complaints.
Dosage
The EU herbal monograph gives semi-solid preparations containing the equivalent of 2-10% herbal substance, applied as a thin layer to the affected area 2 to 4 times daily. Educational reference only, not a prescription.
The EU herbal monograph gives 1-2 g of the flower in 150 mL water as an infusion, used still warm for rinsing and gargling 2 to 4 times daily, or to prepare impregnated dressings for the skin. This is an oromucosal and cutaneous preparation, not an oral tea. Educational reference only, not a prescription.
