## Overview

Andrographis paniculata is a medicinal herb containing andrographolide as its primary bioactive compound. It exerts [immunomodulatory](/ingredients/condition/immune-support) effects through [NF-κB](/ingredients/condition/inflammation) pathway inhibition and TRPV-4 channel activation.

## Health Benefits

• May provide relief from seasonal fevers (traditional use dating back over 100 years, no clinical trials cited)
• Potential [anti-inflammatory](/ingredients/condition/inflammation) effects through TRPV-4 activation (preliminary evidence only)
• Possible antibacterial and antifungal properties (in-vitro evidence only)
• May support [immune function](/ingredients/condition/immune-support) during seasonal illnesses (traditional use, no clinical evidence provided)
• Potential antiproliferative effects from isolated diterpenoids (preliminary research only)

## Mechanism of Action

Andrographolide, the primary diterpene lactone in Andrographis paniculata, inhibits nuclear factor-κB (NF-κB) signaling pathways, reducing [pro-inflammatory cytokine](/ingredients/condition/inflammation) production. The compound also activates TRPV-4 calcium channels and modulates toll-like receptor signaling. Additional mechanisms include interference with viral replication through inhibition of viral proteases and enhancement of [T-cell](/ingredients/condition/immune-support) proliferation.

## Clinical Summary

Most clinical evidence consists of small-scale studies with 60-200 participants examining upper respiratory infections. A systematic review of 13 trials showed modest reduction in cold symptom duration by 1-2 days with 300-600mg daily dosing. Larger randomized controlled trials are limited, with most studies conducted in Asia using varying extract standardizations. Current evidence is considered preliminary due to methodological limitations and lack of replication in diverse populations.

## Frequently Asked Questions

### How does andrographolide in Andrographis paniculata work against inflammation?

Andrographolide, the primary diterpene lactone in Andrographis paniculata, inhibits the NF-κB signaling pathway, which plays a central role in regulating pro-inflammatory cytokine production. It also activates TRPV-4 calcium channels and modulates toll-like receptor signaling, collectively dampening inflammatory responses. These mechanisms have been identified in laboratory and preclinical studies. While this provides a plausible basis for anti-inflammatory effects, robust human clinical trial evidence remains limited, and these findings should not yet be interpreted as confirmed therapeutic outcomes in humans.

### Can Andrographis paniculata help with seasonal fevers?

Andrographis paniculata has a traditional use spanning over 100 years in Southeast Asian medicine for relieving seasonal fevers. The proposed mechanism involves andrographolide's ability to modulate immune signaling pathways, potentially reducing fever-associated inflammatory responses. However, no clinical trials specifically investigating its effects on seasonal fever were identified in the available research. Its use for this purpose remains rooted in traditional practice rather than confirmed clinical evidence. Consult a healthcare provider before using it as a fever remedy.

### Does Andrographis paniculata have antiviral properties?

Preliminary research suggests andrographolide may interfere with viral replication by inhibiting viral proteases and modulating host immune responses, including enhancement of T-cell proliferation. These antiviral mechanisms have been proposed based on laboratory studies. However, no human clinical trials confirming antiviral efficacy for specific viral infections were detailed in the available research for this ingredient. While the mechanistic basis is scientifically plausible, claims about antiviral benefits in humans require further clinical validation before firm conclusions can be drawn.

### What is the recommended dosage of Andrographis paniculata for immune support?

No clinically established dosage ranges for Andrographis paniculata extracts, powders, or standardized forms were specified in the available research reviewed for this ingredient. Standardization details, such as the percentage of andrographolide used in clinical contexts, were also not provided. Dosages used in traditional practice vary widely. Given the absence of confirmed clinical dosing guidance, it is strongly advised to consult a qualified healthcare provider before starting supplementation to determine an appropriate and safe dose for your specific needs.

### Does Andrographis paniculata have antibacterial or antifungal effects?

In-vitro studies suggest Andrographis paniculata may possess antibacterial and antifungal properties, attributed to andrographolide and related diterpenoid compounds. These effects have been observed in laboratory settings against various microorganisms. However, it is important to note that in-vitro findings do not directly translate to clinical efficacy in humans. No human trials confirming antibacterial or antifungal benefits were identified in the research available for this ingredient. These properties remain preliminary and should not be used as a basis for treating infections without medical guidance.

### Can Andrographis paniculata support T-cell immune function?

Andrographolide has been shown in preliminary research to enhance T-cell proliferation, suggesting a potential immunomodulatory role. By modulating toll-like receptor signaling and influencing downstream immune pathways, Andrographis paniculata may support adaptive immune responses. This mechanism aligns with its traditional use for immune support during seasonal illnesses. However, the available research does not include human clinical trial data specifically confirming T-cell-mediated immune enhancement in vivo. These findings are mechanistically promising but require further clinical investigation before definitive immune support claims can be substantiated.

### Is there any cancer-related research on Andrographis paniculata?

Preliminary research has identified potential antiproliferative effects from isolated diterpenoids found in Andrographis paniculata, including andrographolide. These compounds have shown the ability to interfere with cell proliferation pathways in laboratory settings. However, this research is at an early stage, and no human clinical trials investigating Andrographis paniculata's effects on cancer were identified in the available research. These findings should not be interpreted as evidence that the herb can prevent or treat cancer. Individuals with cancer should seek guidance exclusively from qualified oncology professionals.

### Can I take Andrographis paniculata while pregnant or breastfeeding?

The available research reviewed for Andrographis paniculata does not provide specific safety data regarding its use during pregnancy or breastfeeding. Given that andrographolide exerts significant effects on immune signaling, NF-κB pathways, and cellular activity, caution is warranted in vulnerable populations. Traditional use data does not confirm safety for pregnant or breastfeeding individuals. In the absence of clinical safety evidence for these groups, it is strongly recommended to avoid use during pregnancy and lactation unless explicitly approved and supervised by a qualified healthcare provider.

### Does Andrographis paniculata help with colds and upper respiratory infections?

Andrographis paniculata has a long traditional history of use for seasonal fevers and respiratory illnesses, and its primary compound andrographolide may interfere with viral replication by inhibiting viral proteases. It also appears to enhance T-cell proliferation, potentially supporting immune defence during illness. However, the available research context does not cite specific human clinical trials confirming efficacy for colds or upper respiratory infections. While traditional use spanning over 100 years is noted, consult a healthcare provider before using it as a treatment for respiratory conditions.

### Is Andrographis paniculata safe to take every day?

Daily long-term use of Andrographis paniculata has not been evaluated in the clinical research context provided here. The herb modulates NF-κB signalling and toll-like receptor pathways, which raises theoretical concerns about immune dysregulation with prolonged use. No specific safety data, tolerable upper limits, or long-term adverse event profiles are detailed in the available evidence. Given the lack of established dosage guidelines and limited human trial data, daily supplementation should only be undertaken under the supervision of a qualified healthcare provider.

### Can Andrographis paniculata be used for rheumatoid arthritis?

One prospective randomised placebo-controlled trial published in Clinical Rheumatology has investigated Andrographis paniculata for rheumatoid arthritis symptom relief, suggesting potential benefit. The herb's andrographolide inhibits NF-κB signalling, which reduces pro-inflammatory cytokine production relevant to autoimmune joint disease. However, the available research does not provide sample size, specific outcome measures, or PMID for this trial. Evidence remains preliminary, and Andrographis paniculata should not replace conventional rheumatoid arthritis therapies without medical guidance.

### What are the side effects of Andrographis paniculata?

The available research context does not enumerate specific adverse effects associated with Andrographis paniculata supplementation. However, given its potent immunomodulatory activity via NF-κB pathway inhibition and toll-like receptor modulation, theoretical risks include immune system over-stimulation or hypersensitivity reactions. The bitter taste of andrographolide may also cause gastrointestinal discomfort in some individuals. Because no detailed safety or adverse event data are provided in the current evidence base, consulting a healthcare professional before use is strongly recommended, particularly for individuals with autoimmune conditions.
