Key Constituents
Major bioactive saponin with cardio-, neuro-, hepato- and renoprotective effects.
The principal sweet-tasting compound, about 50 times sweeter than sucrose; responsible for the anti-inflammatory, antiviral and gastroprotective activity and also for the pseudoaldosteronism risk on prolonged high-dose use.
Antioxidant and antimicrobial polyphenols, including the skin-lightening compound glabridin.
Minor supporting constituents of the root.
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)
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)

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.
Avoid prolonged use of whole licorice root in large doses. May cause pseudoaldosteronism (hypertension, oedema, hypokalaemia). Contraindicated in hypertension, renal failure, liver disease, hypokalaemia, and pregnancy. DGL form is safer for prolonged gastric use. Interactions with antihypertensives, diuretics, and corticosteroids.
Duke (2002) rates licorice as ++ and documents extensive activities. Glycyrrhizin (the key compound) has anti-inflammatory, antiulcer, antiviral, and adrenal-stimulant properties. Duke highlights an important safety concern: chronic use of licorice can cause pseudoaldosteronism — sodium retention, potassium loss, edema, and hypertension — due to glycyrrhizin's inhibition of cortisol metabolism. This effect is typically seen with >50 g licorice/day for more than 6 weeks. Deglycyrrhizinated licorice (DGL) avoids this side effect. Dose: 5–15 g dried root daily. Contraindicated in hypertension, kidney disease, low potassium, liver cirrhosis, and in combination with diuretics or corticosteroids (Duke, 2002).

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]
Herbaceous perennial legume with pinnately compound leaves of small, oval, slightly sticky leaflets. Pale blue-violet to lilac pea-like flowers are borne in loose spikes, followed by small, flattened, oblong pods. The sweet-tasting rhizome and root system, brownish-grey outside and bright yellow inside, is the medicinal part, spreading extensively underground via stolons.[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]
Grows in dry, sunny, deep-soiled sites, riverbanks and open scrub; native to the Mediterranean region and Western to Central Asia, and cultivated widely for its root.[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 root and rhizome are dug in autumn from plants at least three to four years old, when glycyrrhizin content is highest, then cleaned and dried; sold whole, cut, or as processed extract.[1]
Traditional Uses
Licorice root is one of the oldest and most widely used herbs in the world, with a documented history across Chinese, Ayurvedic, Greek and European traditional medicine as a soothing demulcent and expectorant for coughs and sore throat, a gastroprotective remedy for stomach discomfort and ulcers, and a harmonising, sweetening addition to herbal formulas.[1]
Preparations
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, for adults and elderly, 1.5-2 g of the comminuted root in 150 mL of boiling water as an infusion or decoction 2 to 4 times daily, taken one cup after meals; a soft extract (DER 1:0.4-0.5) at 32 mg 2-3 times daily, not exceeding 160 mg daily, is also listed. The monograph directs that it is NOT to be used for more than 4 weeks, and is not recommended under 18 years - the duration limit matters because prolonged licorice use causes pseudoaldosteronism (sodium and water retention, potassium loss, raised blood pressure). Deglycyrrhizinated licorice (DGL) is preferred where prolonged use is intended. Educational reference only, not a prescription.
