The Short Answer
Andrographis chanoti Dalzell is reported to contain andrographolide-class diterpenoids — the same bitter labdane compounds that characterize the Andrographis genus — which are understood to exert anti-inflammatory and antipyretic effects through inhibition of the NF-κB signaling pathway. Traditional use in Thai ethnomedicine positions the plant primarily as a fever remedy, consistent with the antipyretic pharmacology documented for andrographolides in closely related species such as A. paniculata, though species-specific clinical evidence for A. chanoti itself remains absent from the peer-reviewed literature.

Health Benefits
**Antipyretic Activity**: A
chanoti is used in Thai traditional medicine to reduce fever, a property attributed to andrographolide-class diterpenoids that suppress pro-inflammatory cytokines including TNF-α and IL-6, thereby modulating the hypothalamic thermoregulatory response. The genus-level mechanism involves NF-κB inhibition, which interrupts the cytokine cascade driving febrile states.
**Anti-inflammatory Potential**
Andrographolides present across Andrographis species inhibit NF-κB activation with IC₅₀ values in the low microgram-per-milliliter range for synthetic analogues, reducing downstream mediators such as iNOS, COX-2, and nitric oxide in macrophage models. If A. chanoti shares this phytochemical profile, as its traditional fever use suggests, it may contribute to systemic inflammation reduction.
**Immunomodulatory Support**
Related Andrographis species stimulate T-lymphocyte proliferation and enhance secretion of IL-2 and IFN-γ, suggesting a dual anti-inflammatory and immune-enhancing profile. This immunomodulatory balance may underlie the plant's traditional role in infectious-fever management.
**Hepatoprotective Properties**
Andrographolide has demonstrated hepatoprotective activity in animal models at doses of approximately 100 mg/kg intraperitoneally, reducing paracetamol- and carbon tetrachloride-induced hepatic damage through antioxidant and anti-inflammatory mechanisms. Whether A. chanoti's diterpenoid profile confers similar liver protection remains unconfirmed by direct study.
**Antioxidant Activity**
Species within the Andrographis genus contain polyphenols ranging from approximately 10.23 to 19.52 mg gallic acid equivalents per gram of dried plant material, contributing to free-radical scavenging capacity. This activity may complement the plant's antipyretic use by mitigating oxidative stress associated with febrile illness.
**Antimicrobial Potential**
Genus-wide data indicate that Andrographis diterpenoids and flavonoids exhibit broad-spectrum antimicrobial activity against both gram-positive and gram-negative bacteria in vitro, which is consistent with traditional use of fever-associated infections. Direct antimicrobial data for A. chanoti extracts have not been independently validated.
**Bitter Tonic and Digestive Support**
The intensely bitter diterpene lactone chemistry common to Andrographis species traditionally supports digestive secretion and appetite stimulation, roles documented extensively for A. paniculata in Ayurvedic and Thai classical texts. This bitter tonic action is likely shared by A. chanoti given its phytochemical kinship.
Origin & History
Natural habitat
Andrographis chanoti Dalzell is a lesser-studied species within the Andrographis genus, native to the Indian subcontinent and extending into parts of Southeast Asia, including Thailand, where the genus has long been integrated into traditional botanical medicine. Like its congeners, it likely grows in tropical and subtropical lowland environments with well-drained soils, moderate rainfall, and high humidity, conditions typical of the Acanthaceae family's preferred habitat. Formal cultivation records specific to A. chanoti are sparse, and the plant is primarily encountered as a wild-harvested or semi-cultivated species within its native range.
“Andrographis chanoti Dalzell was described by the Irish botanist Nicholas Alexander Dalzell in his contributions to the flora of the Indian subcontinent during the nineteenth century, placing it within the diverse Andrographis genus that spans South and Southeast Asia. In Thai traditional medicine, members of the Andrographis genus, referred to collectively under related vernacular terms, have been employed as bitter febrifuges and tonics, with preparations typically involving the aerial parts of the plant boiled or macerated in water for consumption during febrile illness. The Andrographis genus more broadly occupies a prominent position in multiple Asian medical traditions — Ayurveda, Siddha, and Thai classical medicine among them — where bitter plants are considered to 'clear heat' and support the body's response to infection, a conceptual framework that aligns with the modern understanding of NF-κB-mediated inflammation. Specific historical references, classical texts, or pharmacopeial listings that name A. chanoti distinctly from A. paniculata or other congeners have not been identified in the accessible literature, suggesting that the species may have been used regionally under shared vernacular names without formal species-level differentiation by traditional practitioners.”Traditional Medicine
Scientific Research
Direct, peer-reviewed scientific studies specifically investigating Andrographis chanoti Dalzell — its phytochemistry, pharmacology, or clinical application — are absent from the current indexed literature as of 2025, representing a critical gap in the evidence base for this species. The evidence available is entirely inferential, drawn from well-characterized congeners such as A. paniculata, which has been the subject of multiple in vitro studies, rodent in vivo models, and a limited number of small-scale human trials examining outcomes such as upper respiratory infection duration, fever reduction, and immune marker modulation. Related species such as A. echioides have been evaluated for terpenoid, flavonoid, saponin, and alkaloid content in stem extracts, with quantified yields including saponins at 0.42 mg/g and alkaloids at 0.27 mg/g, but these cannot be extrapolated to A. chanoti without confirmatory phytochemical screening. Researchers and formulators intending to develop A. chanoti as a commercial ingredient should treat it as a data-deficient species requiring primary phytochemical characterization, pharmacological validation, and ultimately human safety and efficacy trials before evidence-based claims can be substantiated.
Preparation & Dosage
Traditional preparation
**Traditional Decoction (Thai Folk Medicine)**
Aerial parts boiled in water and consumed as a hot tea for fever management; specific volumes and concentrations are not formally documented for A. chanoti and are practitioner-dependent.
**Dried Whole Plant Powder**
Based on genus conventions, crude powder is typically prepared from the aerial parts harvested at early flowering; no species-specific dose has been established for A. chanoti.
**Standardized Ethanolic Extract**
For related Andrographis species, ethanolic extracts standardized to 10–30% andrographolide content are the most pharmacologically characterized form; this standardization framework may be applicable if phytochemical profiling confirms andrographolide presence in A. chanoti.
**Effective Dose Reference (Genus-Level)**
30–200 mg/day for immune support and up to 300 mg/day in respiratory infection protocols; no equivalent dose has been established for A
For A. paniculata, human studies have used andrographolide-equivalent doses of . chanoti.
**Timing Notes**
Genus-wide extracts are typically taken with food to mitigate gastric irritation from bitter diterpenoids; multiple divided doses across the day are preferred in traditional protocols.
**Important Caveat**
All dosage frameworks described here are derived from related species and must not be applied to A. chanoti without species-specific safety and efficacy data.
Nutritional Profile
Detailed macronutrient and micronutrient profiling of Andrographis chanoti has not been published. Based on the phytochemical composition of closely related Andrographis species, the nutritional and phytochemical profile is expected to be dominated by bioactive secondary metabolites rather than significant macronutrient contributions. Relevant phytochemical classes likely present include labdane diterpenoids — most notably andrographolide and potentially neoandrographolide and 14-deoxyandrographolide — at concentrations analogous to those documented in A. paniculata (whole plant andrographolide approximately 4% dry weight, leaf range 0.5–6%, stem 0.8–1.2%). Flavonoids, polyphenols (estimated 10–20 mg gallic acid equivalents per gram in related species), steroids, saponins, tannins, and alkaloids are additionally anticipated based on genus-wide phytochemical screening data. Bioavailability of andrographolides is limited by rapid first-pass metabolism and low aqueous solubility of the lactone scaffold, factors that have driven formulation research in A. paniculata toward cyclodextrin complexation, phospholipid conjugation, and nanoparticle delivery systems — considerations that would be equally relevant to A. chanoti preparations.
How It Works
Mechanism of Action
The primary mechanism of action attributed to Andrographis genus plants centers on andrographolide and its structural analogues, which bear an α-alkylidene γ-butyrolactone moiety that forms covalent adducts with cysteine residues on the p50 subunit of NF-κB, preventing nuclear translocation and transcription of pro-inflammatory genes including those encoding TNF-α, IL-1β, IL-6, iNOS, and COX-2. In LPS-stimulated macrophage models, andrographolide analogues suppress these mediators with IC₅₀ values of approximately 2–2.4 μg/mL. Secondary mechanisms include enhancement of adaptive immunity through upregulation of IL-2 and IFN-γ secretion and promotion of T-cell proliferation, as well as modulation of hepatic CYP enzymes — notably CYP1A1, CYP1A2, CYP3A, and CYP2C9 — suggesting both detoxification support and potential pharmacokinetic herb-drug interactions. If A. chanoti contains the same labdane diterpenoid scaffold confirmed in related Andrographis species, these molecular pathways would be expected to apply, though direct receptor-binding or enzyme-inhibition assays using A. chanoti-derived compounds have not been published.
Clinical Evidence
No clinical trials — randomized, controlled, or observational — have been conducted or published specifically on Andrographis chanoti Dalzell in human subjects as of 2025. Its traditional use for fever in Thai ethnomedicine represents empirical, anecdotal evidence rather than controlled clinical observation, and cannot be assigned a formal evidence grade. By contrast, the most closely related well-studied species, A. paniculata, has been evaluated in small randomized controlled trials for upper respiratory tract infections, with some trials reporting statistically significant reductions in symptom severity scores and duration when standardized andrographolide extracts were administered at doses of approximately 200–300 mg andrographolide per day; however, methodological quality across these trials has been variable, with small sample sizes and inconsistent standardization limiting generalizability. Confidence in any clinical extrapolation to A. chanoti is very low, and the plant should be considered an ethnopharmacologically documented but clinically unvalidated ingredient pending independent investigation.
Safety & Interactions
The safety profile of Andrographis chanoti specifically is undocumented, as no formal toxicological studies — acute, subchronic, or chronic — have been conducted on this species. Extrapolating cautiously from the genus, andrographolide-containing preparations have been associated with adverse effects including hypersensitivity reactions, allergic urticaria, elevated liver enzymes at high doses, and gastric discomfort attributable to the intensely bitter diterpenoid content. Drug interaction risk is a material concern: in vitro studies on Andrographis extracts demonstrate inhibition of CYP3A4 and CYP2C9, which could elevate plasma concentrations of co-administered pharmaceuticals metabolized by these isoforms — including warfarin, cyclosporine, statins, and certain antiretrovirals — and in vivo rodent data suggest CYP2C11 modulation as well. Andrographis species are contraindicated in pregnancy due to potential uterotonic and anti-fertility effects documented in animal models, and use during lactation is not recommended in the absence of human safety data; individuals with autoimmune conditions should use caution given the immunostimulatory properties of andrographolides at low to moderate concentrations.

Frequently Asked Questions
What is Andrographis chanoti used for traditionally?
Andrographis chanoti Dalzell is used in Thai traditional medicine primarily as a treatment for fever, consistent with the antipyretic reputation of the broader Andrographis genus across South and Southeast Asia. The plant is prepared as a decoction of the aerial parts, consumed hot during febrile illness, with the bitter taste considered indicative of its medicinal potency in traditional frameworks.
Does Andrographis chanoti contain andrographolide?
Andrographis chanoti is reported to contain andrographolides — the labdane diterpenoid class that gives the Andrographis genus its characteristic bitter taste and anti-inflammatory pharmacology — but species-specific phytochemical quantification has not been published in peer-reviewed literature as of 2025. In the most studied congener, A. paniculata, andrographolide constitutes approximately 4% of the dried whole plant and 0.5–6% of leaf material, and a comparable profile may exist in A. chanoti pending confirmatory analysis.
Is there clinical research on Andrographis chanoti?
No peer-reviewed clinical trials — human or animal — have been published specifically on Andrographis chanoti Dalzell as of 2025, representing a significant gap in the scientific evidence base. Available evidence is inferential, drawn from extensively studied relatives such as A. paniculata, which has been evaluated in small randomized controlled trials for fever and upper respiratory infections, but these findings cannot be directly applied to A. chanoti without independent validation.
How does Andrographis chanoti differ from Andrographis paniculata?
Andrographis chanoti and A. paniculata are distinct species within the genus Andrographis, differing in morphological characteristics as classified by their respective botanical authors; A. chanoti was described by Dalzell while A. paniculata was described by Burm.f. and later reclassified by Nees. A. paniculata is the dominant commercial and research species with a fully characterized phytochemical profile and multiple human clinical trials, whereas A. chanoti remains botanically described but scientifically undercharacterized, with traditional use recorded but no standardized extracts or validated clinical applications.
Is Andrographis chanoti safe to take?
The safety of Andrographis chanoti has not been formally evaluated in toxicological studies, and no established safe dose exists for this species specifically. Extrapolating from genus-level data, andrographolide-containing Andrographis preparations are generally considered low-risk at moderate doses in healthy non-pregnant adults, but carry risks of allergic reactions, gastrointestinal discomfort, potential CYP3A4 and CYP2C9 drug interactions, and are contraindicated in pregnancy; consultation with a qualified healthcare provider is advised before use.
What is the active compound in Andrographis chanoti that produces its fever-reducing effects?
Andrographis chanoti contains andrographolide-class diterpenoids that are responsible for its antipyretic (fever-reducing) properties. These compounds work by inhibiting NF-κB signaling, which suppresses the production of pro-inflammatory cytokines like TNF-α and IL-6 that trigger fever responses in the hypothalamus. This mechanism allows the herb to modulate the body's temperature regulation at a biochemical level.
Can Andrographis chanoti be used to support immune function beyond fever reduction?
While Andrographis chanoti is traditionally valued for fever reduction, its andrographolide content and NF-κB inhibition suggest broader immune-modulating potential, though this remains less documented than its antipyretic use. The cytokine-suppressing mechanism may help regulate inflammatory responses, but research specifically examining its immunomodulatory effects beyond fever is limited. Clinical studies would be needed to establish its effectiveness for general immune support.
Is Andrographis chanoti bioavailable in traditional herbal preparations, or does it require special extraction?
Traditional Thai medicine uses Andrographis chanoti in various herbal preparations, suggesting that its active diterpenoids have adequate bioavailability through conventional extraction methods. However, andrographolide compounds are generally lipophilic and may benefit from preparation methods that enhance absorption, though specific bioavailability data for A. chanoti extracts is not well-documented in scientific literature. Standardized extracts or preparations with absorption enhancers may offer more consistent potency than raw herb alone.
