Key Constituents
Major bioactive saponin with cardio-, neuro-, hepato- and renoprotective effects.
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.
Pharmacological Actions
Astragalus membranaceus and its constituents (astragaloside IV, cycloastragenol, Astragalus polysaccharide) inhibit tumour growth, invasion and metastasis and enhance antitumour immunity across lung, colorectal and gastrointestinal cancers (preclinical, incl. in vivo).
Immune support / immunomodulation (activates macrophages, NK cells, T and B lymphocytes)
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
Astragalus membranaceus protects against gastrointestinal cancers; astragaloside IV inhibits lung cancer metastasis via macrophage repolarization, cycloastragenol boosts CD8+ T-cell antitumour immunity (with anti-PD-1 synergy), and Astragalus polysaccharide suppresses inflammation-induced colorectal cancer (preclinical).
Supports resistance to colds and respiratory infection (immune)
Adaptogenic tonic for fatigue and low vitality (traditional 'Qi' tonic)
Immune support / immunomodulation (activates macrophages, NK cells, T and B lymphocytes); Supports resistance to colds and respiratory infection (immune)
Supports resistance to colds and respiratory infection (immune)
inferred from anti-inflammatory action
Renoprotective (kidney support) - as an adjunct in chronic kidney disease, reduced proteinuria and raised haemoglobin and serum albumin across trials (Cochrane review; study quality low)
inferred from anti-inflammatory action
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).

inferred from anti-inflammatory action
inferred from anti-inflammatory action
Safety, Cautions & Contraindications
Astragalus stimulates immune activity; on theoretical grounds it should be used cautiously in autoimmune disease and with immunosuppressant medicines (for example after organ transplant) - discuss with a clinician.
Generally well tolerated; high-quality long-term human safety and toxicity data remain limited.
Safety in pregnancy and breastfeeding has not been established; avoid medicinal doses.
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).
External Ids
Botanical Description
Erect perennial herb with a long, fibrous, pale yellow taproot. The leaves are pinnately compound with numerous small, oval leaflets, giving a soft, ferny appearance. Small, pale yellow, pea-like flowers are borne in loose axillary clusters (racemes), followed by membranous, inflated seed pods that give the species its name.[5]
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]
Habitat
Native to the grasslands, sunny slopes and forest margins of northern and north-eastern China, Mongolia and parts of Korea; widely cultivated as a medicinal crop across East Asia.[5]
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]
Harvesting
The root is dug from plants at least four years old, typically in spring or autumn, then cleaned and dried, often sliced into the characteristic pale, fibrous 'coin' slices used in traditional decoctions.[5]
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]
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]
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.
Dosage
The WHO monograph on Radix Astragali gives doses of 3-9 g per day. Traditional Chinese medicine references often cite a considerably higher 9-30 g of dried root per day; WHO's figure is the conservative regulatory-tier one and is stated here in preference. Educational reference only, not a prescription.
Clinical studies commonly use extracts providing the equivalent of several grams of dried root daily, in divided doses. Educational reference only, not a prescription.
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.
