Andrographis paniculata: Benefits, Uses, Dosage & Safety

Andrographis paniculata is a bitter medicinal herb from the Acanthaceae family, often called “King of Bitters.” Its aerial parts (leaves and stems) contain andrographolide, a diterpene lactone that has been studied for its potential to support normal immune function and a healthy inflammatory response. The herb has a long history of use in Ayurveda and Traditional Chinese Medicine as a bitter tonic and general wellness botanical. (Source: Researchgate)

When Bitter Herbs Fit Into a Wellness Routine

Many people use bitter botanicals when they want plant-based support for everyday wellness. Instead of reaching for highly processed products, they look for traditional herbs with a clear history of use and a growing body of modern research.

Andrographis is one of the most studied bitter botanicals in phytotherapy. Below, you will find what it is, how it is traditionally used, which compounds it contains, typical dosing ranges reported in research, and important safety information.

What Is Andrographis – Botanical Overview

Andrographis paniculata is an annual plant native to South and Southeast Asia. Its full botanical name is Andrographis paniculata (Burm.f.) Nees, in the Acanthaceae family. The plant grows quickly, tastes sharply bitter, and prefers warm, humid climates.

Herbalists harvest and use the aerial parts — the leaves and stems, usually in the fall. These parts contain the highest levels of active compounds.

Common Names

King of Bitters is one andrographis common name you will see often, a nod to its sharp taste. Other names include:

Kalmegh (in Ayurveda)
Chuan Xin Lian (in Traditional Chinese Medicine)
Green chiretta
Indian echinacea (a marketing nickname)

That last nickname can cause confusion. The herb is not related to true Echinacea. It also differs from true chiretta (Swertia chirayita), despite the shared “chiretta” label. When you shop, the Latin name is your safeguard. It confirms you have the andrographis herb and not a look-alike.

Active Compounds in Andrographis

The chemistry is what gives this botanical its reputation. The primary compound is andrographolide, a diterpene lactone concentrated in the leaves.

Key constituents include:

Andrographolide — the main diterpene lactone and most researched marker compound.
Neoandrographolide — a related diterpenoid studied for antioxidant activity.
14-deoxyandrographolide — another diterpene in the same family.
Arabinogalactan proteins and flavonoids — plant polyphenols that contribute to antioxidant activity.

Most quality supplements use a standardized andrographis extract. Research formulas are often standardized to 30–50% andrographolide, so each dose remains consistent. Standardization matters because raw leaf can vary from batch to batch.

How Andrographis Works in the Body?

In simple terms, the main compound appears to influence the body’s normal inflammatory signaling pathways.

Research suggests a pathway like this: andrographolide → modulates NF-κB and COX-2 signaling → influences inflammatory mediators. In laboratory studies, the compound has also been observed to affect nitric oxide production in active cells. This is why the herb is associated with support for a healthy inflammatory response, not with treatment of any disease.

On the immune side, andrographolide has been studied for its effects on white blood cell activity. In short, it may help support normal immune function. Because the action touches immune signaling, it also influences who should avoid the herb — more on that below.*

What the Research Suggests About Andrographis

Let us be clear and honest. This is a food-grade herb, not a drug. The points below describe how it may support normal body functions. None of this is a promise to treat, cure, or prevent any condition.*

May Support a Healthy Immune System*

The herb may support normal immune function, because its main compound has been studied for its effect on white blood cells. In one study on immune support, participants took 200 mg daily for 30 days of a standardized extract.*

May Support Respiratory Comfort*

This is the herb’s oldest traditional role. It has centuries of recorded use as a bitter botanical for seasonal respiratory comfort. A clinical study used 200 mg a day for five days of a standardized extract. Participants reported subjective comfort ratings that favored the herb over placebo.*

May Support A Healthy Inflammatory Response*

Andrographolide is the reason this herb is studied for inflammatory-response support. It may support a healthy inflammatory response, because it acts on the NF-κB pathway in laboratory models.*

May Support Everyday Joint Comfort*

The herb could support everyday joint comfort, because small trials on standardized extracts looked at joint function over several months. As always, results vary from person to person.*

May Support Liver and General Resilience*

The herb has a traditional link to liver support, and preclinical studies have examined andrographolide in this area. It may support the body’s own resilience. This area of research is early-stage, so treat it as promising rather than settled.*

Note on medical conditions. Searches often tie this herb to blood sugar, blood pressure, or digestive conditions. Those are medical conditions, and the herb is not a treatment for any of them. If you manage a diagnosed condition, talk with your clinician before using this herb.*

Andrographis Uses & Traditional Context

The andrographis paniculata uses stretch back hundreds of years. In Ayurveda, kalmegh was used as a bitter tonic for digestion and daily balance. In Traditional Chinese Medicine, Chuan Xin Lian was valued for “clearing heat,” a traditional framing for seasonal discomfort and overall balance.

Today, the most common andrographis uses center on everyday immune and respiratory support. Herbalists also value the bitterness itself, since bitter herbs have long been used to support digestion. These andrographis medicinal uses are cultural and historical context, not medical advice.*

Modern andrographis paniculata uses focus on standardized extracts taken for short periods. Tradition and research point in the same direction: seasonal, structure-and-function support for everyday health.*

How to Use Andrographis – Forms & Dosage

You will find this bitter herb in a few forms. Capsules are the most popular, because the taste is truly intense. Tinctures and bulk cut-and-sifted leaf exist for people who prefer traditional preparations.

Because dosing depends on the extract’s strength, standardization is key. Here is what the research has used.

Area of interest	Body system support	Key compound	Amount studied	Traditional / research context
Immune support	May support normal immune function*	Andrographolide	200 mg/day, 30 days	Bitter tonic in Ayurveda & TCM; studied for white-blood-cell activity*
Respiratory comfort	May support respiratory comfort during the colder months*	Andrographolide	200 mg/day, 5 days	The herb’s oldest traditional role; in a short study, comfort ratings favored the extract*
Healthy inflammatory response	May support a healthy inflammatory response*	Andrographolide (NF-κB, COX-2)	Extracts studied in lab models	The hero compound’s most-studied action*
Everyday joint comfort	May support everyday joint comfort*	Andrographolide	300–600 mg/day, up to 3 months	Small trials on standardized extract; results vary by person*
Liver support & resilience	May support normal liver function*	Andrographolide	Preclinical / early-stage	Traditional Ayurvedic bitter tonic; promising, not settled*
Digestive bitterness	Traditionally used to support normal digestion (bitter compound)*	Bitter diterpenes	Traditional use	Bitters have long been taken before meals*
Antioxidant activity	Contains compounds studied for antioxidant activity*	Neoandrographolide, flavonoids	Composition fact	Constituent-level statement, not a product claim*

Simple usage tips:

Take it with food: The bitterness is softer alongside a meal.
Start low: A smaller dose lets you gauge how you feel.
Keep it short-term and seasonal: The herb suits occasional use, not year-round dosing.
Read the andrographolide percentage: A standardized andrographis supplement tells you exactly what you are getting.

An andrographis paniculata supplement should always name its standardization on the label. If it does not, you cannot judge the dose.

Andrographis Side Effects, Safety & Drug Interactions

Most people tolerate short-term use well. Still, honesty matters more than hype. Here are the real side effects to know.

Reported reactions include:

Bitter or metallic taste, and sometimes reduced appetite.
Headache, fatigue, or dizziness.
Digestive upset — nausea, loose stools, or stomach discomfort.
Skin rash or, rarely, allergic reactions.

At high doses, case reports describe swollen lymph nodes. Rare severe allergic reactions have also been linked to some extract products. If you notice hives, swelling, or trouble breathing, stop and seek medical care.

Medication Interactions

Consult your healthcare provider prior to use if you take prescription medications, particularly:

Immune-modulating therapies: Review use with your clinician, as this botanical supports normal immune function.
Circulatory or metabolic therapies: Speak with your provider to ensure compatibility with your wellness routine.
Enzymatic-pathway medications: This herb affects liver enzymes, which may alter how the body processes certain prescription drugs

Who Should Avoid Andrographis?

Some people should not take this herb at all:

Pregnant or breastfeeding people: Adverse and possible abortifacient effects have been documented, so avoid it entirely.
People with autoimmune conditions: An immune-active herb may not suit you.
Anyone scheduled for surgery: Stop well before, due to bleeding-related effects.
Children under two: Herb To Body does not recommend this herb for infants or toddlers.

Conclusion

Andrographis paniculata is a bitter botanical studied for its role in supporting normal body functions. Research has used different extracts and doses, so findings from one product should not be applied to all supplements. As with any botanical, it is wise to speak with a qualified healthcare professional before use, especially if you are pregnant, breastfeeding, have a health condition, or take medication.
