  • The leaves of Andrographis paniculata have been as part of Indian folk medicine and Ayurveda for centuries. The Chinese and Thai herbal medicine systems have also used this herb, mostly for its "bitter" properties, as a treatment for digestive problems and for a variety of fever-causing illnesses. More recently, this herb has become popular in Scandinavia as a remedy for upper respiratory infections (URIs) and the flu.
  • The most widely tested product is a product called Kan Jang® (Swedish Herbal Institute). This product is available with andrographis alone and in combination with Eleutherococcus senticosus.
  • There is reasonably strong evidence from clinical trials to suggest that andrographis effectively reduces the severity and the duration of URIs. Based on animal and laboratory studies, andrographis may have a number of other potential therapeutic uses, including as an anti-inflammatory agent and as a treatment for chemically-induced liver damage. It has also been studied in human clinical trials for the flu and familial Mediterranean fever.

Evidence Table

These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. GRADE *

Research suggests that andrographis may reduce symptom severity and duration in active infections if started within 36-48 hours after symptoms develop. Additional studies are needed, especially those that test the effects of andrographis alone.


Familial Mediterranean fever is a genetic disorder that mainly affects ethnic groups around the Mediterranean causing recurrent episodes of fever and swelling of serous membranes. While early studies suggest that a combination product containing andrographis may reduce the duration, frequency, and severity of attacks among children, more studies using andrographis alone are needed.


Early studies suggest that andrographis may reduce the duration and severity of flu symptoms, as well as the amount of sick time taken of of work by patients with the flu. More research is needed to confirm these results.


Early studies suggest that andrographis extract may help prevent URIs during the winter months if taken daily. Larger studies are required to confirm these results.

Tradition / Theory

The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below.

  • Allergies, antioxidant, atherosclerosis (clogged arteries), blood purifier, blood vessel dilation, cancer, cholera, diabetes, dysentery, fever, gonorrhea, HIV, increasing sperm count, indigestion, inflammation, intestinal worms (), jaundice, liver protection, malaria, male contraception, multiple sclerosis, post-operative recovery, prevention of blood clots, prevention of heart muscle injury, reperfusion injury (prevention), shock, snakebite, vitiligo.


Adults (over 18 years old)

  • Preparations that contain 48-60 milligrams of andrographolide constituents have been taken in divided doses three or four daily for respiratory infections. A 300 milligram Kan Jang® tablet containing 4 percent andrographolides has been taken four times daily for cold treatment (for a total daily dose of 48 milligrams andrographolides). Lower daily doses, such as 200-300 milligrams, have been tested for respiratory infection prevention. Use appears to be safe for up to two weeks. Higher doses may be unsafe and cause side effects. Long-term use of andrographis preparations (beyond two weeks) has not been well studied.
  • Doses of 500-3,000 milligrams of andrographis leaf have been taken by mouth three times daily.
  • For digestive problems, a tea made with one teaspoon of herb per one cup of water, steeped for 5-10 minutes, has been taken with meals.

Children (under 18 years old)

  • There is limited research available in children. Children between ages four and 11 years have taken two tablets three times daily (about 30 milligrams daily of andrographolide and deoxyandrographolide) for 10 days.
  • In Indian Ayurvedic formulas, andrographis leaves and juice are mixed with cardamom, clove, and cinnamon to treat colic and other stomach ailments in infants. However, these uses are not well supported by scientific evidence.


The U.S. Food and Drug Administration does not strictly regulate herbs and supplements. There is no guarantee of strength, purity or safety of products, and effects may vary. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy. Consult a healthcare provider immediately if you experience side effects.


  • There have been cases of severe allergic reactions (anaphylaxis), including one case of shock associated with andrographis.

Side Effects and Warnings

  • Andrographis taken at common doses appears to be relatively safe. Reported side effects include nausea, vomiting, and abdominal discomfort. At high doses (5-10 milligrams per kilogram body weight), patients have experienced nausea, diarrhea, and metallic taste. Rare side effects include headache, dizziness, drowsiness, fatigue, chest discomfort, increased nasal discharge, "blocked nose," and lymph node pain.
  • Use cautiously in patients with low blood pressure, diabetes or bleeding disorders.

Pregnancy and Breastfeeding

  • Andrographis is not recommended during pregnancy due to possible contraceptive effects observed in animal studies. Safety during breastfeeding is unknown. In theory, andrographis may decrease sperm count.


Interactions with Drugs

  • Andrographis may increase the risk of bleeding. Use cautiously in patients taking anticoagulant agents, such as warfarin (Coumadin®) or heparin or with anti-platelet agents such as ibuprofen (Motrin®, Advil®) or clopidogrel (Plavix®). Andrographis use should be stopped before some surgeries; discuss this with a healthcare professional.
  • Andrographis may lower blood pressure and may therefore, add to the effects of drugs taken to lower blood pressure. Patients with high or low blood pressure who are considering taking any of these agents should discuss options with their healthcare professionals. Dosing adjustments may be necessary.
  • Andrographis may decrease blood sugar and may add to the effects of drugs taken to lower blood sugar, including insulin. Patients should be closely monitored by their healthcare professionals because dosing adjustments may be necessary.
  • Andrographis may also interact with allergy, anti-inflammatory, anti-cancer, antiviral, fertility, and immunomodulatory drugs.

Interactions with Herbs and Dietary Supplements

  • Andrographis may increase the risk of bleeding. Use cautiously in patients taking anticoagulant agents. Multiple cases of bleeding have been reported with the use of Ginkgo biloba, and fewer cases with garlic and saw palmetto. Numerous other agents may theoretically increase the risk of bleeding, although this has not been proven in most cases.
  • In theory, andrographis may lower blood pressure and may therefore, add to the effects of agents that also lower blood pressure. Patients with high or low blood pressure who are considering taking any of these agents should discuss options with their healthcare professionals.
  • Andrographis may lower blood sugar. Patients taking other herbs or supplements that may affect blood sugar levels, such as bitter melon (Momordica charantia), should be monitored closely by a healthcare professional while taking andrographis.
  • Andrographis may also interact with anti-inflammatory, anti-cancer, antiviral, immunomodulatory, and fertility herbs and supplements.
