Botanical Description

Erect, branching annual herb with a slender, quadrangular (square-sectioned), dark green stem. The leaves are opposite, lance-shaped and glabrous, with a short stalk. Small, two-lipped, white flowers with purple-pink markings are borne in loose, spreading axillary and terminal racemes. The whole plant, and especially the leaves, is intensely and characteristically bitter.[11]

Habitat & Distribution

Native to India and Sri Lanka and widely distributed through South and Southeast Asia, growing wild in plains, hillsides, roadsides and cultivated fields; also grown commercially as a medicinal crop.[11]

Harvesting

The aerial parts (leaves and tender stems) are cut just before or at the onset of flowering, when andrographolide content is typically highest, and dried in shade to preserve the bitter diterpenoid lactones.[11]

Parts: Aerial parts (leaves and herb)
Season: Before to early flowering

Key Constituents

Diterpenoid lactones[2, 3, 10, 11]

Andrographolide is the principal active compound; also neoandrographolide and deoxyandrographolide.

Flavonoids[11]

Antioxidant and anti-inflammatory constituents.

Polyphenols and other phenolics[11]

Contribute to antioxidant activity.

Phenolic compounds

Pharmacological Actions

Anti-inflammatory[2, 7, 9, 10, 11]
Anticancer (preclinical)[15, 16, 17]

Andrographolide, the principal diterpene lactone of Andrographis paniculata, suppresses proliferation and induces apoptosis across breast, lung, colon, cervical, hepatic and haematological cancers via NF-kappaB and PI3K/Akt inhibition (preclinical).

Cancer (anticancer research)[15, 16, 17]Preliminary · 2/10

Andrographolide (from Andrographis paniculata) acts as a chemopreventive and antitumour agent against breast, lung, colorectal, cervical, prostate and hepatocellular cancers and leukaemia, inducing apoptosis and inhibiting NF-kappaB and PI3K/AKT signalling (preclinical).

Traditional Use & History

Andrographis, the 'king of bitters', is a cornerstone bitter tonic of Ayurvedic and traditional Chinese medicine (Chuan xin lian), used for fevers, colds, sore throat, infections and liver complaints. This traditional reputation for treating the common cold and upper respiratory infections is now supported by clinical trials of standardised extracts.[10, 13]

Preparations

Infusion/decoction[11]

Dried aerial parts infused or lightly decocted in hot water as a very bitter traditional fever and cold remedy.

Standardised extract[10, 13]

Extract standardised to andrographolide content, taken as tablets or capsules; the form used in most clinical trials for cold/URTI symptom relief.

Dosage

Standardised extract[10, 13]

Clinical trials for upper respiratory infection commonly use extracts standardised to around 60-120 mg andrographolide daily, in divided doses, for up to 5-7 days. Educational reference only, not a prescription.

Dried herb[14]

The WHO monograph on Herba Andrographidis gives, by indication - for the common cold, 1.5-3.0 g of the powdered crude drug three times daily, after meals and at bedtime; for pyrexia, a decoction from 3 g of the crude drug twice daily; for diarrhoea, a decoction from 3-9 g as a single dose as needed, or two 500 mg tablets four times daily. Note that the EMA HMPC assessed this herb and issued a public statement rather than a monograph, so there is no EU posology. Educational reference only, not a prescription.

Safety, Cautions & Contraindications

Safety note[10, 18]Caution

Avoid in pregnancy and when trying to conceive: high doses have shown reproductive toxicity in animals and the herb has a traditional reputation as an abortifacient.

Safety note[10]Caution

High doses have caused nephrotoxicity and reproductive toxicity in studies; use standardized products at recommended doses and avoid prolonged high-dose use.

Safety note[10, 18]Caution

May lower blood pressure and blood sugar and may interact with anticoagulant/antiplatelet, antihypertensive and immunosuppressant medicines; allergic reactions can occur.

Harvest Readiness

[12]

Part: aerial-parts
Signals: Cut the aerial parts (leaves and herb) at the flowering stage, when most plants are in bloom, leaving 10-15 cm of stem at the base for regrowth.
Basis: traditional
Source Quote: The plants at flowering stage (90-120 days after sowing) is cut at the base leaving 10-15 cm stem for plant regeneration.
Species Confirmed: 1
Notes: Purdue NewCROP fact sheet (REF-3199). The parenthetical day-count is a cultivation guide, not a latitude-invariant signal; the observable stage is flowering. Single source -> provisional.
