## Overview

Andrographis paniculata is a medicinal herb containing andrographolide as its primary bioactive compound. It supports [immune function](/ingredients/condition/immune-support) by enhancing T-cell activity and provides [hepatoprotective](/ingredients/condition/detox) effects through bile flow stimulation.

## Health Benefits

- Enhances immune response by increasing [T-cell](/ingredients/condition/immune-support) activity, which helps the body combat infections more effectively. - Reduces fever by inhibiting prostaglandin synthesis, providing a natural antipyretic effect. - Supports [liver health](/ingredients/condition/detox) by promoting bile flow, aiding in detoxification and reducing liver enzyme levels. - Alleviates symptoms of the common cold by reducing nasal congestion and throat irritation. - Acts as an [anti-inflammatory](/ingredients/condition/inflammation) by suppressing cytokine production, which can help manage chronic inflammatory conditions. - Improves [digestive health](/ingredients/condition/gut-health) by stimulating digestive enzymes, enhancing nutrient absorption and reducing bloating. - Provides [antioxidant protection](/ingredients/condition/antioxidant) by neutralizing free radicals, reducing oxidative stress and cellular damage.

## Mechanism of Action

Andrographolide activates nuclear factor-κB (NF-κB) signaling pathways, enhancing T-lymphocyte proliferation and cytokine production. The compound inhibits cyclooxygenase and lipoxygenase enzymes, reducing inflammatory [prostaglandin](/ingredients/condition/inflammation) synthesis. In the liver, andrographolide stimulates choleretic activity by increasing bile acid synthesis through CYP7A1 enzyme activation.

## Clinical Summary

Multiple randomized controlled trials involving 200-400 participants demonstrate andrographis extract (300-400mg daily) reduces upper respiratory infection duration by 1.5-2 days. A 12-week [hepatoprotective](/ingredients/condition/detox) study with 60 subjects showed 28% improvement in ALT levels with standardized andrographolide extract. [Immune function](/ingredients/condition/immune-support) studies indicate 40-60% increases in T-cell activity markers, though most trials are short-term (4-12 weeks). Evidence is moderate quality with consistent results across Asian populations.

## Frequently Asked Questions

### Does andrographis paniculata help with cold and flu symptoms?

Yes, andrographis paniculata has demonstrated efficacy in reducing cold and flu symptoms in multiple randomised controlled trials. Its primary bioactive compound, andrographolide, inhibits cyclooxygenase and lipoxygenase enzymes, suppressing prostaglandin synthesis responsible for congestion, throat irritation, and general malaise. Clinical studies suggest it can shorten illness duration and reduce symptom severity, particularly nasal congestion and sore throat, when taken early during infection. Standard extracts at 400–600 mg daily are typically used during acute illness episodes.

### How does andrographis paniculata boost the immune system?

Andrographolide, the key bioactive in andrographis paniculata, activates NF-κB signalling pathways, which stimulate T-lymphocyte proliferation and enhance cytokine production. This mechanism directly increases T-cell activity, improving the body's adaptive immune response against pathogens. By priming immune cells before or during infection, andrographis helps mount a faster and more effective defence. This immunomodulatory action makes it particularly useful as a preventive supplement during cold and flu season or periods of immune vulnerability.

### Can I take andrographis paniculata every day long-term?

While andrographis paniculata is generally well tolerated at 400–600 mg daily for short-term use, long-term daily supplementation requires caution. Current research primarily supports use during acute infections rather than continuous long-term protocols. Prolonged use may cause gastrointestinal discomfort in some individuals. It is advisable to cycle the supplement — using it during illness or for defined periods — and consult a healthcare provider before committing to extended daily use, particularly if you have underlying health conditions or take medications.

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

Andrographis paniculata is generally considered safe at recommended doses of 400–600 mg per day, but some individuals may experience side effects including nausea, vomiting, diarrhoea, stomach discomfort, and headache. Rare cases of allergic reactions have been reported. High doses may cause fatigue or a bitter taste. Because andrographolide influences cytokine production and immune signalling, individuals with autoimmune conditions should use it cautiously. Pregnant women should avoid it, as it may have uterotonic effects. Always consult a healthcare provider before starting supplementation.

### Can I take andrographis paniculata with other immune supplements like zinc or echinacea?

Andrographis paniculata can generally be combined with immune-supporting supplements like zinc or echinacea, and some commercial formulations already pair these ingredients. Both andrographis and echinacea enhance T-cell activity through complementary but distinct mechanisms, potentially offering additive immune support. Zinc supports immune cell development independently. However, combining multiple immunomodulatory agents may over-stimulate immune activity in sensitive individuals or those with autoimmune conditions. There are no well-documented dangerous interactions, but consulting a healthcare provider before stacking immune supplements is recommended for personalised guidance.

### Does andrographis paniculata help with digestive health and bloating?

Andrographis paniculata may support digestive health by stimulating the production of digestive enzymes, which can improve nutrient absorption and reduce bloating. Its choleretic activity — increasing bile acid synthesis via CYP7A1 enzyme activation — also promotes bile flow, which is essential for fat digestion and overall digestive efficiency. Traditional Ayurvedic and Asian medicinal use has long included andrographis as a digestive bitter tonic. While clinical evidence specifically for bloating relief is limited, its multi-pathway digestive support makes it a reasonable adjunct for gut health at standard doses.

### Is andrographis paniculata safe during pregnancy?

Andrographis paniculata is generally not recommended during pregnancy. Animal studies and traditional medicinal knowledge suggest andrographolide may possess uterotonic properties, meaning it could stimulate uterine contractions, potentially raising the risk of miscarriage or preterm labour. There is insufficient robust clinical evidence to establish safety in pregnant women. Out of caution, pregnant women and those planning to conceive should avoid andrographis paniculata supplementation entirely. Breastfeeding women should also consult a healthcare provider before use, as safety data in this population is similarly limited.

### Does andrographis paniculata have antioxidant properties?

Yes, andrographis paniculata provides meaningful antioxidant protection. Andrographolide and related compounds neutralise free radicals, reducing oxidative stress and limiting cellular damage associated with chronic disease and ageing. This antioxidant activity complements its anti-inflammatory mechanisms — since oxidative stress and inflammation are closely linked — by suppressing both free radical accumulation and cytokine-driven inflammatory cascades. While andrographis is not primarily marketed as an antioxidant supplement, its free radical scavenging capacity adds a valuable secondary benefit alongside its immune-supporting and hepatoprotective properties at standard doses of 400–600 mg daily.

### How much andrographis paniculata should I take daily?

The typical recommended dosage of Kalmegh (Andrographis paniculata) extract is 400–600 mg per day. Dosages used in clinical studies for cold and flu symptoms often fall within this range, standardised to andrographolide content. It is advisable to split doses across the day with meals to improve tolerability. Always consult a healthcare provider before starting supplementation, particularly if you have underlying health conditions or are taking prescription medications.

### Does andrographis paniculata reduce fever naturally?

Yes, andrographis paniculata has demonstrated natural antipyretic properties. Its primary bioactive compound, andrographolide, inhibits cyclooxygenase and lipoxygenase enzymes, thereby reducing the synthesis of prostaglandins — the key mediators responsible for raising body temperature. This mechanism is similar to how conventional anti-inflammatory drugs work but through a natural pathway. While it may help manage mild fever, it should not replace medical treatment for high or persistent fevers.

### Is andrographis paniculata good for liver health?

Andrographis paniculata shows notable hepatoprotective properties. Andrographolide stimulates choleretic activity by activating the CYP7A1 enzyme, increasing bile acid synthesis and promoting bile flow, which aids liver detoxification. Studies suggest it may help reduce elevated liver enzyme levels, indicating reduced hepatic stress. These effects make it a potential supportive supplement for liver health, though individuals with existing liver conditions should consult a healthcare provider before use.

### Can andrographis paniculata help with inflammation and chronic inflammatory conditions?

Andrographis paniculata exhibits significant anti-inflammatory activity. Andrographolide modulates NF-κB signalling pathways and suppresses the production of pro-inflammatory cytokines, while also inhibiting cyclooxygenase and lipoxygenase enzymes to reduce prostaglandin synthesis. These combined mechanisms may help manage chronic inflammatory conditions. Clinical evidence is more robust for acute infections, but its multi-pathway anti-inflammatory action makes it a promising adjunct for managing ongoing inflammation under medical supervision.
