Body Dispersal of Andro - G

When consumed, andrographolides appear to accumulate in organs throughout the viscera. In one study, after 48 hours, the concentration of labelled andrographolide was :

20.9%, brain; 14.9%, spleen; 11.1%, heart; 10.9%, lung; 8.6%, rectum; 7.9%, kidney; 5.6%, liver; 5.1%, uterus; 5.1%, ovary;and 3.2%, intestine. Reference (6).

Absorption and excretion is rapid:

80% is removed within eight hours via the kidney (urine) and G.I. tract.

90% is eliminated within forty-eight hours.

Effects in the Body – Immune System

Using signal transduction technology, extracts of AP(Andrographis paniculata) have been found to counteract interference with the cell cycle. Such interference is the basis for the development of cancer or infection with viruses such asHIV-1.

Andrographolides are thought to enhance immune system functions such as production of white blood cells (scavengers of bacteria and other foreign matter), release of interferon, and activity of the lymph system. Interferon is a protein (called a cytokine) made by cells in response to viruses. It is a potent antiviral agent and is also antiproliferative (stops the growth of viruses).

Mice studies have shown that Andrographis paniculata is a potent stimulator of the immune system in two ways: (1) Antigen-specific response: antibodies are made to counteract invading microbes, and (2) Nonspecific immune response: macrophage cells scavenge and destroy invaders.

AP activates both responses - making it effective against a variety of infectious and oncogenic (cancer-causing) agents.

Effects in the Body – Immune SystemContd.

If a cancer cell can be made to mature (or differentiate), it will not have the ability to grow out of control. Researchers are therefore searching for substances that can cause cancer cells to mature. In one study of mice, researchers searched for naturally occurring substances that would cause differentiation of leukemia cells. Leukemia is a cancer of the white blood cells. AP was chosen because it contained substances (terpenes) that were similar to substances found in other plants that were known to cause differentiation of cancer cells. The results of the study demonstrated that AP had potent cell differentiation-inducing activity on leukemia cells. (13)

Abnormal Cell Growth

In addition to causing cancer cell maturity or differentiation, AP extracts from the leaves of the plant are also cytotoxic (cell-killing) against cancer cells. This cancer cell-killing ability was demonstrated against human epidermoid carcinoma (squamous cell carcinoma) of the skin lining of the nasopharynx and against lymphocytic leukemia cells. (14). It was the andrographolide component that was found to have the cancer cell-killing ability. This ability for killing cancer cells was superior to the levels of the effectiveness recommended by the National Cancer Institute for a cytotoxic substance.

Killing Cancer Cells

Additional details of cancer trials are given in the book, Miracle Herbs by Stephen Holt, M.D., wherein cancer studies done at Roswell Park Cancer Institute Buffalo, New York, showed that AP extract has an antiprostate cain ncer action comparable to that of the widely used and highly toxic agent cisplatin - without the toxicity.

Prostate

Exciting recent research has indicated that extracts of AP may have great promise for interfering with the viability of the HIV virus.

H I V

…scientists found that AP contained substances that destroyed the virus's communications mechanism. One component of the herb -- andrographolide -- prevented transmission of the virus to other cells and stopped the progress of the disease by modifying cellular signal transduction.

Here a Macrophage Cell with its Helper T Cell is eating a Virus

The B Cell which will make the antibodies to weaken or kill the Virus, now interacts

with macrophage and T Cell

T Cell Activity

The HIV virus attaches itself to the helper T cell. Through a series of manipulations of the helper cell's genetic machinery, the virus tricks the cell into producing chemicals that the virus needs. HIV takes over the "machinery" of the helper T cell and thus becomes a virus production factory that is no longer part of the immune system. Without the T-cells, the other components of the immune system do not receive any messages to produce antibodies and resistance to HIV is seriously compromised.

H I V - Mechanics

Cooperative research at the National Cancer Institute has shown that andrographolide can also inhibit HIV's toxic effect on cells.

…researchers at the China Academy of Traditional Chinese Medicine in Beijing reported that AP was one of the herbs that had an inhibitory effect on HIV replication. (7). Leukemia cells in particular have been shown to be very sensitive to the effects of andrographolide. (13).

Toxin Inhibition

The Common ColdThe prevention of the common cold with an extract of AP was shown in a pilot double-blind study. Students were given Kan Jang, a formulation of AP produced by the Swedish Herbal Institute, and were diagnosed for the presence or absence of colds during a three-month period. (16). A dose of 200 mg/day was given to the study group. After one month there was no signficant difference in the number of colds. However, after the third month of intake of Kan Jang there was a significant decrease in the incidence of colds as compared to the placebo group. The students that got the Kan Jang had a rate of incidence of colds of 30% compared to 62% for students that received the placebo. The relative risk of catching a code indicated that the preventive effect could be due to the presence of andrographolide, which has known immuno-stimulant effects.

The amount of Kan Jang used in the previous study was much less than used in a previous study that produced quicker results. In this study, patients were divided into two groups, one of which received 1,200 mg/day of Kan Jang. (17). These patients already had colds with symptoms including nasal discharge, nasal stuffiness, sore throat, earache, cough, fever, headache, and malaise. At the beginning of the study, the patients receiving Kan Jang, and those receiving a placebo had similar symptoms. The symptoms, such as tiredness, shivering, sore throat, and muscular aches, diminished significantly on the fourth day of treatment with Kan Jang. The researchers concluded that treatment with Kang Jang (standardized to 4 percent andrographolides) accelerated the recuperation of patients from the common cold.

Cold Symptoms

•The ability of AP to lower fever has been demonstrated independently in several laboratories. Rat studies done in China have shown that andrographolide, neoandrographolide, and dehydroandrographolide can lower the fever produced by different fever-inducing agents, such as bacterial endotoxins (toxic chemicals released from bacteria), pneumococcus, hemolytic streptococcus, typhoid, paratyphoid, and the chemical 2,4-di-nitro-phenol. (19).

Anecdotal evidence shows relief from Menopausal Hot Flushes and the heat associated with stomach inflammation due to food poisoning.

Fever

AP extract was found to possess anti-ulcerogenic activity. It reduced the development of ulcers by 31%, while the standard ulcer drug, cimetidine had an 85.43% reduction rate. Andrographolide caused a significant decrease in total stomach acidity and acid stomach juice secretion, without the cost and side effects associated with ulcer therapy.

Ulcers

The anti-inflammatory effects of various AP compounds have been shown in many studies in which the inflammation was produced by chemicals. Inflammation caused by histamine, dimethyl benzene, croton oil (hemolytic necrosis), and acute pneumocystis produced by adrenaline was significantly reduced or relieved. (22). This effect was observed for all major andrographolides: deoxyandrographolide, andrographolide, neoandrographolide, and dehydroandrographolide.

Anti-Inflammatory

Edema

In research done on the anti-inflammatory activity of naturally occurring products, AP was found to inhibit edema (swelling due to fluid trapped in tissues). At a concentration of 200 mg/kg body weight, AP significantly inhibited (by 60%) edema at three hours. (24)

MalariaMalaria is still a prevalent disease in many tropical and subtropical countries. It is difficult to eradicate because the parasites that carry malaria become resistant to the drugs used to treat the disease. Extracts of AP containing the four active components previously mentioned were evaluated for antimalarial activity against Plasmodium berghei, one of the parasites that transmit malaria. The extract was found to produce considerably inhibition of multiplication of the parasites.

AP extracts are also effective in killing filaria (microscopic worms) that obstruct lymph channels in the body, leading to gross swelling termed elephantiasis. The study was done in dogs. Since no toxic effects were apparent, researchers believed that the AP plant extract would be safe for humans. No plant has previously been shown to have antifilarial action.

Filaria

DiarrheaDiarrhea-type diseases are one of the top ten causes of death worldwide and are a leading cause of death in children in developing countries, especially those that are under five years of age.

Acute bacterial diarrhea in patients was treated with a total dose of 500 mg andrographolide divided over three dosing periods per day for six days (2.5 to 3.0 mg/kg of body weight). This regimen was combined with rehydration. There were 66 cures of 80 patients treated -- an 82.5% cure rate. Seven additional patients responded favorably to the treatment and only seven patients (8.8%) did not respond. The effectiveness of the treatment was confirmed by laboratory tests of stool samples. (23). In another study, AP was used to treat 1,611 cases of bacterial dysentery and 955 cases of diarrhea with overall effectiveness of 91.3%. (22).

Researchers at the Tonga Medical University in China have demonstrated that AP given to dogs one hour after development of (heart attack) decreased the damage that occurred to the heart muscle. (29). Such damage occurs after the blood supply is restored to the muscle. This is due to a sudden influx of oxygen (which produces free radicals that damage tissue) and abnormally high amounts of calcium.

In subsequent studies at the same university, the researchers demonstrated by electrocardiograph that abnormal changes in heart readings were prevented by pretreatment with AP. Also, clumping of platelets (the blood particles that initiate clotting) was inhibited and no clot (thrombus) that could cause infarction was induced. (29). An added effect of AP was that it activated fibrionolysis, the natural process in the body that dissolves clots. (18).

Cardio-Vascular (1)

Another way to prevent cardiovascular disease is to correct high blood pressure. Researchers have reported that an extract of AP produced anti-hypertensive (blood pressure lowering) effects. (18).

Researchers believe that AP has this anti-hypertensive effect because it relaxes the smooth muscle in the walls of blood vessels. This relaxation prevents the blood vessel from constricting and limiting blood flow to the heart, brain, and other organs in the body. AP keeps blood, and therefore oxygen, flowing to the brain. Diminished blood flow to the brain can cause short-term memory loss, ringing in the ears, dizziness, headaches, depression, and impaired mental performance.

Cardio-Vascular (2)

AP has clear anti-fertility (male and female) as well as pregnancy-terminating effects.

It is not recommended for use during pregnancy, nor when attempting pregnancy.

Fertility

Infective hepatitis is an acute inflammatory condition of the liver. It is often followed by liver cirrhosis and may progress to a coma and death. In India, where ancient physicians used AP to treat similar liver ailments, a study was conducted to evaluate the effect of AP in infective hepatitis. There was marked improvement in the majority of patients tested, when given a decoction or infusion of AP. Appetite improved on the fifth day of treatment, jaundice (yellow color of conjunctive of the eye and skin) gradually diminished and completely disappeared within 24 days, and fever subsided after 7 days on average. Other indications of effectiveness of AP included improvement in liver function tests. The researchers concluded that AP was a useful remedy for treatment of infective hepatitis.

Hepatitis

The andrographolides present in AP are potent stimulators of gallbladder function. In animal experiments, those that received andrographolides for seven consecutive days showed an increase in bile flow, bile salts, and bile acids. These increases are beneficial and result in enhanced gallbladder function.

Use of AP might, therefore, decrease the probability of gallstone formation and might also aid fat digestion. The andrographolides also prevented decreases in the amount of bile that are caused by acetaminophen toxicity. (15).

Gall Bladder Function

Nervous System

Many compounds do not penetrate the blood-brain barrier. However, andrographolide does so and concentrates in the brain and particularly in the spinal cord. (7). Several studies have shown that AP products have a sedative effect. In mice given barbital as anesthesia, the animals became sedated more quickly and the anesthesia lasted longer.

Also, it was possible to give less of the anesthesia if it was given along with AP. (19). The studies indicate that AP products may act at the barbital receptors in the brain.

Respiratory SystemAndrographolide has been used to treat tonsilitis, respiratory infections, and tuberculosis. In one study, AP was used to treat 129 cases of acute tonsilitis. Sixty-five percent of patients responded to the therapy. (32).

The same authors used andrographolide to treat 49 pneumonia patients. Thirty five cases were found to show positive changes and nine patients completely recovered. In another study, andrographolide was used to treat 111 patients with pneumonia and twenty with chronic bronchitis and lung infection.

The overall effectiveness of AP treatment was 91%. Fever subsided within three days in 72% of the patients and 40% of these patients had smaller areas of infection within one week.

Leptospirosis is a disease caused by the bacterium Leptospira interrogens. Infection with this organism results in fever, hemorrhagic (blood-containing) lesions, central nervous system dysfunction, and jaundice.

Several studies have reported efficacy in approximately 80% of patients treated with deoxyandrographolide, andrographolide, and neoandrographolide tablets. (34).

Leptsporisis Infection

Acute pyelonephritis is an inflammation of the kidney, particularly due to local bacterial infection. In a study evaluating the effectiveness of AP in treating this disease, AP was compared with nitrofurantoin, a standard clinical drug for pyelonephritis therapy, AP was found to be as effective as the standard drug, but with fewer side effects. (36).

Kidney - Nephritis

In Traditional Chinese Medicine (TCM) and in systems of healing in Thailand and India, AP has long been perceived as safe. Although trial and error in humans may not be considered scientific, it is a way of determining whether a substance is effective or harmful. When scientists began to investigate the safety of AP, formal toxicological studies in animal models and in animal and human clinical trials confirmed that andrographolide and other members of this AP family of compounds have very low toxicity.

Rarely, people who use AP experience dizziness and heart palpitations. As with all herbs, some people will have an allergic reaction to AP. The other side effect, as discussed above, is anti-fertility. Overall, evidence to date indicates that andrographolides are naturally occurring compounds with low toxicity when used appropriately.
