What is andrographis paniculata?

Also known as green chiretta, from the perspective of TCM it refers to the whole plant or leaf of Andrographis paniculata (Burm.f.) Nees. In China, this herb mainly grows in Guangdong, Fujian, and other provinces.

And the aerial parts contain diterpenoid, including 3, 14-di-deoxyandro-grapholide, 14-deoxyan-drographoside (14-deoxyandrographolide-19-β-D-glucoside, andropanoside), andrographiside (andrographolide-19-β-D-gluco-side), andographolide, neoandrographolide, 14-deoxy-11,12-didehydroandrographolide, and 14-dioxyandrographolide.

Andrographis benefits

As mentioned at the start of this article, andrographis is rich in nutrition and has fabulous medical values. Here are the main health benefits it possesses.


Antibacterial effect

Compared to chloramphenicol and furazolidone, the neoandrographolide contained has a better clinical efficacy against the bacillary dysentery. What’s more, this herb has no side effects and toxicity. The tests performed in vitro showed that both andrographis decoction and the isolated crude crystals can inhibit or kill some types of the leptospira, and inhibit pneumococcus, streptococcus, and catarrhalis to some degree.

Antiviral effect

The decoction of Andrographis paniculata has a delay effect on the degeneration of human embryonic kidney cells, which is caused by orphan virus of ECHO11.

Other effects

Its decoction and water extract (alcohol-added decoction with precipitates removed) have no obvious effect on rabbit hearts in vitro. And significant vasorelaxant effect showed after the isolated rat hind legs were perfused with water extract. No significant effect on blood pressure showed after the intravenous injection on anesthetized dogs with 0.1 g crude drug / kg of the above-mentioned preparations. Both of them have no significant effect on isolated guinea pig ileum and rat uterus. In addition, the decoction but water extract inhibits the isolated rabbit duodenum.

Andrographis related Chinese herbal formulas

TCM believes that andrographis is bitter and cold in properties. And it covers four different meridians, such as heart, lung, large intestine, and urinary bladder. Its main functions are heat-clearing and detoxifying, cooling blood, and reducing swelling. Its main indications and uses are wind-heat type cold and flu, fever in febrile disease, cough caused by lung heat, pertussis, pulmonary abscess, swollen sore throat, yeast infection, jaundice with damp-heat pathogen, stranguria, erysipelas, sore and ulcer, eczema, lyme disease, candida, strep, sinus infection, shingles, acne, snakebite, and so on. Usual dosage is from 9 to 15 grams, in decoction normally. Sometimes the dose can be up to 30 to 60 grams according the diagnosis. And 0.6 to 3 grams should be used in the form of powder, loaded into capsules preferably.

It is for a good reason to name this herb as Chuan Xin Lian in China. As you can see, bitter is always considered as one of the most sensitive tastes, which by many, if not all, regard as uncomfortable, intense, or annoying. Similarly, in the theory of Five Elements in Chinese medicine, bitter is perceived as a negative taste and associated with the heart. And as long as you chew a small piece of Andrographis leaves, you can immediately feel that kind of unforgettable bitterness, just like penetrating straight into your heart. For this reason, it is named “Chuan Xin Lian”, namely “through the heart lotus” if translated word for word.

Potential andrographis side effects and contraindications

Andrographis paniculata has very low toxicity. After taking orally crude crystals 10g/kg, mice reduced activity, often closed their eyes, and looked as if they were asleep. After the anatomy, the organs looked normal with the naked eye, including heart, kidney, liver, spleen, and others. After daily fed orally with 0.5g/kg for 10 straight days, nothing unusual found on mice’s growth, appetite, bowel movement, mental status, red cell count, hemoglobin and leukocyte count, and so on.

TCM wise, care should be taken in the case of lack of vital energy and deficiency-cold in spleen and stomach. And adverse reactions do occur when taking a variety of large dose of Andrographis and its oral preparations. The common symptoms include gastrointestinal discomfort and loss of appetite. It has been reported that Chuan Xin Lian pills and Andrographis injection can cause drug eruption, upper abdominal pain, anaphylactic shock, and even death in severe cases.

    I was given the Chuan Xin Lian Wan by a holistic doc. for an unspecified bacterial or viral intestinal infection. He sugested a v. high dose but I by nature am v. cautioned with everything and check side effects of everything including vitamins and all kind of other supplements. I’m not taking that high dose but much more less specially to avoid some blood thinner effect since, long time ago I got some bleeding problem. I hope I’m safe with just two three times a day and with probiotic too ? Please advise.

    I was prescribed this by a Chinese doctor for a case of over-active bladder.
    Altho it did not help the bladder issue, it did help a little to regulate my bowels.
    I suppose this is bec. as you say above, andrographis covers 4 meridians, two of them are the bladder and the bowel.
    But I do not read where it is suggested for either bladder or bowel issues.
    That confuses me.
    Can you shed some light?
    Thank you.

      Adrographis will work for an infected “over-active bladder,” but not a weak bladder, in fact it may aggravate it. The doctor who gave this presumed that some infectious element contributed to your condition. The bladder and large intestine are two of the channels and organs that it works on. This herb is not usually prescribed for chronic conditions and would be a unique selection for aging-related conditions
