Key Constituents
Major bioactive saponin with cardio-, neuro-, hepato- and renoprotective effects.
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)
Adaptogen for stress and anxiety (improves stress scores and well-being in trials)
Cognitive support - a placebo-controlled study in healthy adults found improved reaction time and accuracy and shorter P300 latency
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)

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
Adaptogen for stress and anxiety (improves stress scores and well-being in trials)
inferred from anti-inflammatory action
Supports blood-sugar control (lowers fasting and post-meal glucose)
inferred from anticancer action
inferred from neuroprotective 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 well tolerated; mild nausea has been reported. Its blood-sugar-lowering effect means caution alongside antidiabetic medicines.

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 subshrub (Lamiaceae), 30-75 cm tall, with erect, much-branched, hairy stems often tinged purple. Leaves are opposite, ovate-oblong with a toothed margin, and release a strong, clove-like (eugenol) scent when crushed. Small purplish-pink, two-lipped flowers are borne in elongated terminal racemes. The plant is held sacred in Hindu tradition (Tulsi).[11]
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]
Native to the Indian subcontinent and tropical Asia, now cultivated and naturalised throughout the tropics and subtropics worldwide; commonly grown in home gardens and temple courtyards as well as cultivated as a medicinal and aromatic crop.[12]
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]
Leaves are harvested year-round from actively growing plants, ideally picked once morning dew has dried; whole flowering tops are also gathered.
Traditional Uses
Tulsi is one of the most revered plants in Ayurvedic medicine, traditionally used as an adaptogen for stress, a remedy for respiratory complaints (colds, cough, asthma), and a general immune tonic. Modern clinical trials support adaptogenic/anti-stress, blood-sugar-lowering and immunomodulatory effects consistent with these traditional uses.[3, 12]
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.
Clinical trials for stress and mood have used standardised dry-extract capsules taken over several weeks; dosing varies by product concentration, so follow the manufacturer's guidance. Educational reference only, not a prescription.
The WHO monograph on Folium Ocimi Sancti gives a daily dosage of 6-12 g of the crude drug as a decoction. This is a whole-day total for the fresh or dried leaf, notably higher than the 1-2 g per cup often quoted in popular sources. Educational reference only, not a prescription.
