Aloe Vera Benefits

Aloe vera is one of the only known natural vegetarian sources of Vitamin B12, and it contains many minerals vital to the growth process and healthy function of all the body’s systems. Numerous studies worldwide indicate that aloe vera is a general tonic for the immune system, helping it to fight illness of all kinds. Various research studies are underway to explore the potential of aloe vera components to boost immunity and combat the HIV virus, and to treat certain types of cancer (particularly leukemia). It may even have a role to play in managing diabetes.

Over 200 worldwide scientific research papers have been published on the effects of Aloe vera. The three main categories of research include anti-inflammatory, anti- bacterial, and anti-viral actions of Aloe vera. The juice is said to soothe digestive tract irritations such as colitis, ulcers and irritable bowel syndrome. Aloe’s ability to encourage the release of pepsin (a gastric juice enzyme necessary for digestion) when the stomach is full is a possible reason for its ulcer-healing effects (Journal of the American Osteopathic Society, 1963, vol.62). In one study, oral use of Aloe for six months helped mitigate asthma symptoms in almost half of the participants. Eleven of twenty-seven patients studied who drank Aloe reported feeling better at the end of the study. Researchers think that results might be due to stimulation of the immune system, as well as naturally occurring anti-inflammatory agents in Aloe vera.

On-going studies worldwide show that Aloe taken in highly concentrated doses can stimulate the production of white blood cells that may help fight viruses and also tumours. Latin Name: L.

Aloe vera contains protein, calcium, magnesium, zinc, vitamins A, B12 and E, essential fatty acids and is naturally rich in:

Vitamin C which helps maintain tone of blood vessels and promotes good circulation and is essential to the health of the adrenal gland which supports our body in times of stress.

Amino acids which are chains of atoms constructing protein in our body.

Enzymes, which are the life-principle in every live, organic atom and molecule of natural raw food, rejuvenate aged tissues and promote healthy skin.

Germanium which is a mineral that some health authorities claim therapeutic benefits for: immunodeficiency, pain, cardiac disorders, circulatory disturbances and eye problems.

Aloe vera juice is said to be one of the finest body cleansers, cleaning morbid matter from the stomach, liver, kidneys, spleen, bladder, and is considered the finest, known colon cleanser. Studies have shown that it is healing and soothing in the relief of indigestion, stomach distress and ulcers. People claim relief from arthritis, bladder and kidney infections; leg cramps, constipation, hemorrhoids, insomnia, and for vaginitis, it is said to be an excellent vaginal douche. An excellent internal tonic for energy and well being Aloe juice may add greatly to the strength of the food fed, digestive tract, skin, and overall good health and happiness.

It is also used to ease heartburn, ulcers, diverticular disorders, and other types of digestive upset. It is used as an anti-inflammatory and may be taken internally as a remedy for certain digestive complaints. European folk medicine calls for using Aloe vera juice to relieve heartburn and ulcers. Preliminary research has shown promising results. Clinical trials in Japan indicate that certain compounds in Aloe vera reduce the secretion of stomach juices and the formation of lesions.

Animal studies and anecdotal reports claim that drinking Aloe vera juice or taking it as a tablet or capsule can reduce swelling and inflammation in arthritic joints. Drinking Aloe vera juice may also help those asthmatic patients who are not dependent on cortico-steroids.

In 1997, University of San Antonio researcher Jeremiah Herlihy, Ph.D., conducted a study to observe any negative effects of drinking Aloe daily. Rather than exhibiting negative effects, however, test animals receiving daily Aloe showed a remarkable reduction in leukemia, heart disease, and kidney disease. Dr. Herlihy concluded, “We found no indication of harm done to the rats even at high levels.” In fact, the Aloe-drinking animals actually lived 25 percent longer than those in the control group (IASC Conference, Texas, 1997).

There is no single ingredient that makes Aloe vera potent and healthful. Researcher Robert Davis, Ph.D., an endocrinologist-biologist, explains that fifteen different compound groups of nutrients work together to make the plant effective. This means that Aloe vera’s effects cannot be synthesized easily in a laboratory. On the upside, this makes the plant useful across a wide spectrum of circumstances. And because the various elements that make Aloe effective are nutrients rather than drugs, Aloe juice may complement medical treatments. In fact some cancer patients state that Aloe vera seems to reduce nausea, increase energy, and may help to minimize low blood counts caused by chemotherapy or radiation.

Ellagic acid is a phytochemical, or plant chemical, found in raspberries, strawberries, cranberries, walnuts, pecans, pomegranates, and other plant foods.

Overview

Research in cell cultures and laboratory animals has found that ellagic acid may slow the growth of some tumors caused by certain carcinogens. While this is promising, at this time there is no reliable evidence available from human clinical studies showing that ellagic acid can prevent or treat cancer. Further research is needed to determine what benefits it may have.

How is it promoted for use?

Ellagic acid seems to have some anti-cancer properties. It can act as an anti-oxidant, and has been found to cause cell death in cancer cells in the laboratory. In other laboratory studies, ellagic acid seems to reduce the effect of estrogen in promoting growth of breast cancer cells in tissue cultures. There are also reports that it may help the liver to break down or remove some cancer-causing substances from the blood.

Some supporters have claimed these results mean that ellagic acid can prevent or treat cancer in humans. This has not been proven. Unfortunately, many substances that show promise against cancer in laboratory and animal studies are not found to be useful in people.

Ellagic acid has also been said to reduce heart disease, birth defects, liver problems, and to promote wound healing.

What does it involve?

The highest levels of ellagic acid are found in raspberries, strawberries, and pomegranates, especially when they are freeze-dried. Extracts from red raspberry leaves or seeds, pomegranates, or other sources are said to contain high levels of ellagic acid and are available as dietary supplements in capsule, powder, or liquid form. The best dose of these preparations is not known.

What is the history behind it?

Ellagic acid was studied in the 1960s mainly for its effects on blood clotting. Early published research on ellagic acid and cancer first appeared in the 1970s and 1980s. With the publication of several small laboratory studies in the mid-1990s, ellagic acid began to be promoted on the Internet and elsewhere as a means of preventing and treating cancer.

What is the evidence?

Almost all studies conducted on ellagic acid to date have been done in cell cultures or laboratory animals. Several animal studies have found that ellagic acid can inhibit the growth of tumors of the skin, esophagus, and lung, as well as other tumors caused by carcinogens. Other studies have also found positive effects. A recent study in cell cultures found that ellagic acid may act against substances that help tumors to form new blood vessels. Further studies are needed to determine whether these results apply to humans.

In the only study reported thus far in humans, Italian researchers found that ellagic acid seemed to reduce the side effects of chemotherapy in men with advanced prostate cancer, although it did not slow disease progression or improve survival. The researchers cautioned that more research would be needed to confirm these results.

The interaction between phytochemicals like ellagic acid and the other compounds in foods is not well understood, but it is unlikely that any single compound offers the best protection against cancer. A balanced diet that includes 5 or more servings a day of fruits and vegetables along with foods from a variety of other plant sources such as nuts, seeds, whole grain cereals, and beans is likely to be more effective in reducing cancer risk than eating one particular food, such as raspberries, in large amounts. However, some studies suggest that foods high in ellagic acid might be useful additions to a balanced diet. For example, one nonrandomized clinical study of men with prostate cancer reported that pomegranate juice slowed the increase in blood levels of prostate-specific antigen, a substance that is routinely measured to estimate growth of prostate cancer.

Practitioners of Chinese medicine use astragalus root to enhance the body’s energy, known to [...]]]> Astragalus root is derived from a perennial plant that grows in northern China and Mongolia. The herb is a staple of Chinese medicine, where it has been used for centuries to boost the immune system and treat a variety of ailments.

Practitioners of Chinese medicine use astragalus root to enhance the body’s energy, known to them as “qi” (pronounced as “chee”). Ancient people used it to enhance strength and regulate metabolism. The herb has only recently gained popularity among herbalists and practitioners of alternative medicine in the West.

The major chemical components of astragalus root are polysaccharides, flavonoids saponins and a series of triterpene glycosides known as “astragalosides”. Some of these are known to be biologically active, and may play roles in preventing/treating certain diseases.

In-vitro and rodent studies conducted in America support the assertion that astragalus root can enhance the immune system. For example, it may reduce the severity of atopic dermatitis and asthma. Nonetheless, human clinical trials are lacking, so the benefits of astragalus supplementation for these conditons are unclear at this time.

A great deal of research on astragalus has been conducted in China. Chinese studies indicate that astragalus may ameliorate the effects of cancer chemotherapy and improve the quality of life. Astragalus root appears to induce production of interferon, a chemical that is an essential part of the immune system and has been widely studied for its ability to fight the development of cancer.

Some interesting, albeit speculative, in-vitro research also suggests that astragalus compounds may be useful in the fight against diseases such asAIDS and lupus; not to mention aging.

Beyond the above, astragalus and/or individual components may exert cardioprotective effects, by improving blood flow, reducing inflammation and preventing myocardial injury.

Astragalus is also a mild diuretic, and increases natiuresis (sodium excretion). It may even prove useful for treating insulin resistance and chronic fatigue syndrome.

This plant is native to Northern China and Mongolia and inhabits mostly pine forests and sandy soils. Chinese doctors have used astragalus herb to fight the common cold and the flu.

Composition

Astragalus root has polysaccharides that have a role in influencing the immune system. Astragalus root also contains saponins called astragalosides and astramembranosides, along with flavonoids and triterpenes. Three major flavonoids are ononin, formononetin, and demethylhomopterocarpin.

Aplastic anemia

Clinical study on effect of Astragalus Injection and its immuno-regulation action in treating chronic aplastic anemia.

Chin J Integr Med. 2007. TCM Hospital of Langfang City, Chinese Hemopathic Therapeutic Center of TCM, Hebei, China.

Sixty patients with aplastic anemia were randomly assigned to two groups equally, both were treated with Stanozolol three times a day, 2 mg each time through oral intake, but astagalus was given additionally to the patients in the treated group once a day via intravenous dripping. All were treated for 15 days as one therapeutic course and the whole medication lasted for more than 4 months totally, with follow-up adopted. Astragalus injection could promote the recovery of hemopoietic function, which might be through improving T-lymphocyte subsets and reducing the release of negative regulatory factors such as TNF-alpha and IL-2 to alleviate the inhibition on hemopoietic function.

Hypoglycemic effect of polysaccharide enriched extract of Astragalus membranaceus in diet induced insulin resistant C57BL/6J mice and its potential mechanism.

Phytomedicine. 2009. Department of Pathophysiology, Medical College of Wuhan University, Hubei Provincial Key Laboratory of Allergy and Immune-Related Diseases, Wuhan, China.

Astragalus polysaccharide exerts insulin-sensitizing and hypoglycemic activities in type 2 diabetic rats. The present study was designed to confirm the hypoglycemic effect of Astragalus polysaccharide and to investigate its possible mechanism underlying the improvement of insulin resistance in vivo and in vitro. We found Astragalus polysaccharide could alleviate insulin resistance induced by high glucose. The hyperglycemia, hypolipemia, and hyperinsulinemia status were controlled with Astragalus polysaccharide therapy. Insulin action in the liver of insulin resistant mice was restored significantly with Astragalus polysaccharide administration. The anti-obesity effect and hypolipidemia effects of Astragalus polysaccharide were probably due partly to decreasing the leptin resistance of mice, which would positively couple with the normalization of plasma insulin levels. We have shown that Astragalus polysaccharide has beneficial effects on insulin resistance and hyperglycemia.

Cancer and use with chemotherapy drugs
Astragalus membranaceus has been used to ameliorate the side effects of anti-neoplastic drugs.

Astragalus membranaceus prevents daunorubicin-induced apoptosis of cultured neonatal cardiomyocytes: role of free radical effect of Astragalus membranaceus on daunorubicin cardiotoxicity. Phytother Res. 2009. Shanghai Institute of Hematology, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.

Anthracyclines are antitumor antibiotics with significant activity against solid and hematologic malignancies. One problem preventing more widespread use has been the development of cardiotoxicity. To determine whether antioxidant agents can reduce the cardiotoxicity of anthracyclines, Astragalus membranaceus was introduced. Pre-treatment with Astragalus membranaceus significantly attenuated the daunorubicin-induced increases of reactive oxygen species, apoptosis and the secretions of LDH in cultured neonatal cardiomyocytes. Compared with Astragalus membranaceus, N-acetyl-l-cysteine had similar effects on daunorubicin-induced cell injury. Our results suggested that Astragalus membranaceus is potentially protective against daunorubicin cardiotoxicity by decreasing free radical release and apoptosis in cultured neonatal cardiomyocytes.

Fatigue

Astragalus membranaceus flavonoids (AMF) ameliorate chronic fatigue syndrome induced by food intake restriction plus forced swimming.
J Ethnopharmacol. 2009; National Research Institute of Chinese Medicine, Taipei, Taiwan, ROC.

Alteration of immune function may be associated with chronic fatigue syndrome (CFS) and this study reveals the immunoregulatory effect of Astragalus membranaceus flavonoids. Rats were induced by food intake restriction plus forced swimming for 6 weeks. An atrophied spleen associated with a significantly decreased spleen/body weight ratio and a reduced spleen cells proliferation was found in these rats when compared with home cage controls.

Astragalus membranaceus flavonoids given orally at 20, 50 and 100mg/kg body weight once a day consecutively for 6 weeks recovered the reduced cell proliferation. A switch to Th1-dominated immune regulation was observed in these rats as the cultured splenocytes produced more interleukin-2 (IL-2) but less IL-4 when compared with controls. Supplementation with Astragalus membranaceus flavonoids counteracted the aberrant cytokine production and rats receiving Astragalus membranaceus flavonoids exhibited higher endurance capacity to swim when compared with those without the herb. Alterations of immune function may be associated with CFS and the tonic effects of Astragalus membranaceus flavonoids against CF may be attributable to balance the abnormal cytokine level by isoflavones.

Heart failure
Astragalus has protective effect on heart tissue and may be helpful in congestive heart failure.

Study on effect of Astragalus injection in treating congestive heart failure.
Zhou ZL, Yu P.Third People’s Hospital, Hangzhou.

To observe the clinical efficacy and side-effects of Astragalus Injection in treating congestive heart failure (CHF). Eighty-three CHF patients with heart function of II-IV grade assessed by New York Heart Association classification were randomly divided into 2 groups. The 42 patients in the treated group were treated with astragalus 40 ml (equivalent to 80 g crude drug) by adding in 5% glucose solution 500 ml for intravenous dripping, once a day and the 41 patients in the control group were treated by nitrolingual injection. The therapeutic course in both groups was 2 weeks and the patients were followed-up for 1- 6 months. The clinical heart function improvement rate and the total effective rate in the astragalus treated group after 1 month treatment were 26% and 78%, and after 6 months were 34% and 81% respectively, which were superior to those in the control group significantly. The levels of left ventricular ejection fraction, fractional shortening of left ventricular short axis, stroke volume, cardiac output  and the cardiac index were all improved in both groups, but better improvement was shown in the astragalus group. Follow-up study showed that the incidence of cardiac event was lower in the astragalus group than that in the control group. Astragalus can be viewed as one of the important auxiliary drugs for treatment of CHF especially in severe cases. 

Immune system

Astragalus improves certain parts of the immune system, and may have some anti-HIV activity. It’s not clear whether astragalus would have anti-HIV activity when ingested as a supplement.

Astragalus and kidney disease

Astragalus may be helpful in diabetic nephropathy. This herb may also act as a diuretic.

Protective effects of Astragalus saponin I on early stage of diabetic nephropathy in rats.
J Pharmacol Sci. 2004.

Diabetic nephropathy (DN) has become the leading cause of end stage failure, but no renoprotective treatment has been very available for use in DN. Astragalus saponin I, a component extracted from Astragalus membranaceus, was studied in experimental DN induced by administration of streptozotocin in male rats. The early DN rats were treated with 3 doses of astragalus for 8 weeks to analyze its efficacy with different parameters. By comparison with vehicle-treated DN rats, the renal hypertrophy, the oxidative stress intensity, and the blood glucose level of DN rats were ameliorated by astragalus. Also, the microalbuminuria level, advanced glycated end-products either in serum or in kidney cortex, and the aldose reductase activity were significantly reduced. The results suggest that astragalus has therapeutic effects on several pharmacological targets in the progress of DN and is a potential drug for prevention of early stage DN.

Aqueous extract of Astragali Radix induces human natriuresis through enhancement of renal response to atrial natriuretic peptide.
J Ethnopharmacol. 2008; Department of Nephrology & Rheumatology, Shanghai Tenth People’s Hospital, Tongji University, Shanghai, China.

The diuretic effect of astragalus root in humans was described in ancient books, but its mechanism has not been identified. To evaluate its diuretic / natriuretic effect, we conducted a double-blind, randomized, crossover study in 12 healthy men. They were randomized to receive either placebo or a single oral dosage of 0.3g/kg body weight of aqueous extract of astragalus root. Compared with placebo, astragalus root treatment markedly increased urinary sodium excretion, fractional sodium excretion, and urinary excretion of chloride during the first 4h. No significant changes of these parameters were observed during 12h or 24h. We show here that astragalus root induces a marked natriuresis in healthy men, which is attributed to enhanced renal responses to endogenous A-type Natriuretic Peptide. The Astragaloside IV in the astragalus root is not the active component for natriuresis.

Effect of Astragalus membranaceus and Angelica sinensis combined with Enalapril in rats with obstructive uropathy.
Phytother Res. 2009. Wojcikowski K, Wohlmuth H, Johnson DW, Gobe G. Molecular and Cellular Pathology, School of Medicine, University of Queensland, Brisbane, Queensland, Australia.

ACE inhibitors (ACEi) reduce renal tubulointerstitial fibrosis but are not completely effective. Combined extract of Astragalus membranaceus and Angelica sinensis (A&A) is a traditional antifibrotic agent in China. The present investigation aimed to determine whether an ACEi (Enalapril) and A&A together have a better antifibrotic effect in unilateral ureteral obstruction (UUO) than monotherapy with either agent. Male Sprague-Dawley rats had either sham operation or UUO alone, with A&A (combined aqueous and ethanol extract equivalent to 2.1 g dried herbs), with Enalapril (in drinking water at 200 mg/mL) or with both treatments. Kidney and liver were collected for protein extraction or fixed for histologic stains, immunohistochemistry (IHC), microscopy. Enalapril or A&A individually were antifibrotic. Transforming growth factor-beta1, fibroblast activation, collagen deposition, macrophage accumulation and tubular cell apoptosis were all decreased. The combination of the two drugs was significantly more effective than Enalapril alone in reducing tumor necrosis factor-alpha, collagen accumulation, activation of fibroblasts, and tubular cell apoptosis. In conclusion, Enalapril with A&A significantly decreased tubulointerstitial fibrosis to a greater extent than treatment with Enalapril alone.

Skin and melanin

Inhibitory effects of calycosin isolated from the root of Astragalus membranaceus on melanin biosynthesis.
Biol Pharm Bull. 2009; Korea Research Institute of Bioscience and Biotechnology, Daejeon, Korea.

Tyrosinase is a key enzyme for melanin biosynthesis, and hyperpigmentation disorders are associated with abnormal accumulation of melanin pigments, which can be reduced by treatment with depigmenting agents. A methanol extract of Astragalus membranaceus showed inhibitory activity against mushroom tyrosinase. The active compound was purified from the methanol extract of Astragalus membranaceus and, following several chromatographic methods, was identified as calycosin. The results showed that calycosin exhibited tyrosinase inhibitory activity. Calycosin showed a melanin biosynthesis inhibition zone in a culture plate of Streptomyces bikiniensis, which is commonly used as an indicator organism. Furthermore, calycosin dramatically reduced melanin synthesis of Melan-a cells without any apparent cytotoxicity and reduced expression of melanogenic enzyme, tyrosinase. These results suggest that calycosin may be an effective skin-lightening agent that regulates the expression of melanogenic enzymes.
