Herb Description

Andrographis is an herbal medicine derived from the Andrographis Paniculata shrub grown the moist, shady areas of India, China and throughout Southeast Asia. It is commonly referred to as 'Indian Echinacea' and is a popular Ayervedic and Chinese household remedy for the common cold, digestive issues, upper respiratory tract infections, flu and other sicknesses typified by fever. Although its use dates back easily a thousand years in these ancient medical traditions, there is a more recent historical reference to its potency. In the Indian flu epidemic of 1919, the herb Andrographis is credited with the reversal of its onslaught. More recently, it popularity has spread to Scandinavia, where its dosages have been standardized and it has been widely recommended by doctors for two decades as a common remedy in treating these same winter ailments.


Pharmacology

Andrographolide isolated from Andrographis paniculata induces cell cycle Flavonoids and andrographolides from Andrographis paniculata. Two flavonoids, identified as 5,7, tetramethoxyflavanone and 5-hydroxy-7, trimethoxyflavone, as well as several other flavonoids, andrographolide diterpenoids, and polyphenols, were obtained from the phytochemical investigation of the whole plant of Andrographis paniculata, a well known medicinal plant.Anti-malarial activity of some xanthones isolated from the roots of Andrographis paniculata.

Four xanthones were isolated from the roots of Andrographis paniculata. In vitro study revealed that compound 1,2-dihydroxy-6,8-dimethoxy-xanthone possessed substantial anti-plasmodial activity against Plasmodium falciparum Anticancer and immunostimulatory compounds from Andrographis paniculata.


Uses of Andrographis paniculata

As research increases, so is our understanding of Andrographis' many activities and indications are that it may even play a role in cardiovascular and cancer treatments.
Potential benefit of andrographis paniculata supplements

*For colds and flu

Long known in traditional Asian medicine as an immune system booster, Andrographis paniculata has demonstrated significant activity in fighting common cold, flu, and upper respiratory infections. Two randomized double-blind, placebo-controlled parallel group clinical trials were performed to investigate the effect of a standardized extract (SHA-10) of Andrographis paniculata fixed combination (Kan jang) in the treatment of uncomplicated upper-respiratory tract infections. In both studies, throat symptoms were found to show the most significant improvement.

Anti-inflammatory

Andrographis paniculata contains many flavonoids, which have anti-inflammatory properties. Andrographolide, an active component of andrographis paniculata, inhibits inflammatory responses by rat neutrophils.

Anti-tumor
Andrographis paniculata has anti-carcinogenicity properties.


Diabetes
The ethanolic extract of andrographis possesses antidiabetic property. Its antidiabetic effect may be attributed at least in part to increased glucose metabolism.


Immune system

Most flavonoids have anti-microbial activity and have a positive effect on the immune system. Andrographis has demonstrated significant activity in fighting common cold, flu, and upper respiratory infections.


Mind

Andrographis extract exhibited a significant alteration in behavior pattern and a reduction in spontaneous motility in animals. The extract also produced a prolongation of the pentobarbitone-induced sleeping time and lowered the body temperature in different experimental animal models.


Anti-oxidant and liver protection

Andrographis paniculata treatment prevents BHC induced increase in the activities of enzymes y-Glutamyl transpeptidase, glutathione-S-transferase and lipid peroxidation. The activities of antioxidant enzymes like superoxide dismutase, catalase, glutathione peroxidase and the levels of glutathione were decreased following BHC effect. Administration of andrographis showed protective effects in the activity of superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase as well the level of glutathione. The activity of lipid peroxidase was also decreased. The result indicate antioxidant and hepatoprotective action of andrographis.

summary

Andrographis paniculata has been evaluated in the laboratory and has shown potential in a number of conditions, however, since human research is lacking, the potential andrographis health benefits and androgrpahis side effects are, at this time, not fully known. If you do plan to take an andrographis supplement, take at least 2 days off a week and one week off a month. It is also not clear how andrographis herb would interact with other herbs that influence the immune system such as Astragalus root herb, echinacea herb, Goldenseal herb, and others.


How it works :

Andrographis paniculata extract is traditionally used as a medicine to treat different diseases in India, China and Southeast Asia. In the present study, we evaluated the anticancer and immunomodulatory activity of the methanolic extract of Andrographis paniculata in human cancer and immune cells. The methanolic extract of Andrographis paniculata was fractionated into dichloromethane, petroleum ether and aqueous extracts and screened for bioactivity. Our results indicate that the dichloromethane fraction of the methanolic extract retains the active compounds contributing for both the anticancer and immunostimulatory activity. Dichloromethane fraction significantly inhibits the proliferation of HT-29 (colon cancer) cells and augments the proliferation human peripheral blood lymphocytes at low concentrations. On further fractionation of the dichloromethane extract we could isolate three diterpene compounds. Andrographolide showed anticancer activity on diverse cancer cells representing different types of human cancers.
Acute respiratory infections represent a significant cause of over-prescription of antibiotics and are one of the major reasons for absence from work. The leaves of Andrographis paniculata (Burm. f.) Wall ex Nees (Acanthaceae) are used as a medicinal herb in the treatment of infectious diseases. Systematic literature searches were conducted in six computerised databases and the reference lists of all papers located were checked for further relevant publications. Information was also requested from manufacturers, the spontaneous reporting schemes of the World Health Organisation and national drug safety bodies. No language restrictions were imposed. Seven double-blind, controlled trials (n = 896) met the inclusion criteria for evaluation of efficacy. All trials scored at least three, out of a maximum of five, for methodological quality on the Jadad scale. Collectively, the data suggest that Andrographis is superior to placebo in alleviating the subjective symptoms of uncomplicated upper respiratory tract infection. There is also preliminary evidence of a preventative effect. Adverse events reported following administration of Andrographis were generally mild and infrequent. There were few spontaneous reports of adverse events. Andrographis may be a safe and efficacious treatment for the relief of symptoms of uncomplicated upper respiratory tract infection; more research is warranted.
Double-blind, placebo-controlled, randomized, pilot clinical trial of ImmunoGuard--a standardized fixed combination of Andrographis paniculata Nees, with Eleutherococcus senticosus Maxim, Schizandra chinensis Bail. and Glycyrrhiza glabra L. extracts in patients with Familial Mediterranean Fever.
Double blind, randomized, placebo controlled pilot study of ImmunoGuard--a standardized fixed combination of Andrographis paniculata, Eleutherococcus senticosus, Schizandra chinensis, and Glycyrrhiza glabra special extracts standardized for the content of Andrographolide (4 mg/tablet), Eleuteroside E, Schisandrins and Glycyrrhizin, was carried out in two parallel groups of patients. Both the clinical and laboratory results of the present phase II (pilot) clinical study suggest that ImmunoGuard with andrographis s a safe and efficacious herbal drug for the management of patients with FMF.

Antimicrobial activity of Andrographis paniculata.The antimicrobial activity of aqueous extract, andrographolides and arabinogalactan proteins from Andrographis paniculata were evaluated. The aqueous extract showed significant antimicrobial activity, which may be due to the combined effect of the isolated arabinogalactan proteins and andrographolides.



Clinical Applications

Andrographis and its various components have demonstrated a variety of effects in the body. Aspects stimulate the general immune activities, others inhibit the body's inflammatory mechanism and still others demonstrate not only anti-microbial abilities, but also are instrumental in killing certain tumor cells. Studies have also indicated that the active chemical, Andrographolide, helps to stop the clumping of blood platelets which is the clotting process that can lead to heart attacks.


Side Effects & Safety

Andrographis Paniculata has been widely tested and is considered safe with few if any minor side effects at commonly prescribed levels. In clinical trials with children between 4 and 11 Andrographis was effective and safe. Side effects occurred in HIV trials at a dose of 10 mg of andrographolides per kg of body weight or roughly 12 time the recommended dosage.



Precautions

Pregnant women or those trying to conceive should avoid Andrographis animal studies have shown the possibility of contraceptive effects at high dosages. Safety during lactation is not known. Andrographis may increase glucose metabolisation which could unduly enhance blood sugar lowering medication.
