  • Olive leaf complex is quite simply one of the most useful natural compounds I’ve ever encountered. It’s a powerful health tonic that’s fantastic for general well-being and enhanced immunity.

    Let me explain.

    The olive plant is a rich source of such beneficial plant compounds as tocopherols, flavonoids, anthocyanins, sterols and polyphenols. “The real benefit of olive oil is that it delivers these amazing polyphenols,” says David Rubin, MD, MSc, an Israeli researcher and biochemist.

    What are Polyphenols, Anyway?
    Polyphenols are a group of valuable chemicals found throughout the plant kingdom primarily in berries, walnuts, olives, teas, grapes and other fruits and vegetables. They have a wide variety of health benefits. And the fresh leaves of some olive trees are loaded with them.

    These polyphenols also have antimicrobial activity against a wide variety of viruses, bacteria, yeasts and fungi.

    Scientific advances have shown there are at least 30 distinct polyphenols in fresh-picked olive leafs and that the full spectrum of these polyphenols in fresh-picked olive leaves gives a synergistic effect greater than any individual isolated compound alone. This is why the most bioeffective olive leaf products on the market today are always made directly from fresh-picked, whole olive leaves which provide the whole spectrum of natural polyphenolic antioxidants just as nature intended. This also enables them to work together in natural synergy to maximize the health benefits.

    How is Your Immune System Functioning?
    Immunity is one of the keys to good health. Think for a moment about the last time something was “going around” your office. Some people got really sick but others probably didn’t. And even among those who did, whatever “bug” was going around probably laid some people out for two weeks while others were back to work after a day or so.

    The difference? The performance of the Immune System.
    We can’t do much about the bugs and microbes we’re all exposed to—but what we can do is strengthen and support our immune system.

    Olive Leaf Complex Can Help.
    Here are some of the questions you might ask yourself if you’re interested in evaluating just how well your immune system is functioning:

    • Do you get infections frequently?
    • Do you have frequent colds?
    • Do you get the flu?
    • Do you experience inflammation or infection in the
    • upper respiratory tract?
    • Do you suffer from bronchitis frequently?
    • Do you have recurrent skin infections?
    • Have you ever suffered from recurrent infections of
    • Candida or “yeast infections”?
    • Have you been diagnosed with Epstein-Barr or chronic fatigue syndrome?
    • Do you experience a reduction in stamina and resistance, especially when under stress?
    • Are your energy levels less than you would like them to be?

    Any or all of these can be symptoms of compromised immunity.

    What about Olive Leaf for Bacteria and Viruses?
    Your best defense against the potential damage of bacteria and viruses is to have a strong, robust immune system that will prevent them from taking root and doing harm in the first place.

    Fresh-picked olive leaf complex can be a powerful weapon in the battle between your immune system and invading microbes. The bitter substances in olive leaves—since identified as the polyphenols we’ve been talking about throughout this article (oleuropein, hydroxytyrosol, caffeic acid, verbascoside, etc.) have been found to be particularly helpful in resisting bacterial damage. In fact, early research by the drug company Upjohn found extracts from olive leaves to be effective in treating infection caused by a large number of viruses as well as bacteria and parasitic protozoans.

    According to James R. Privitera, MD, these are some of the unique properties possessed by the olive leaf compound for the broad killing power:

    • Olive leaf has an ability to interfere with critical amino acid production essential for viruses.
    • Olive leaf has an ability to control viral infection and/or spread by inactivating viruses or by preventing virus shedding, budding or assembly at the cell membrane.
    • Olive leaf extract has the ability to directly penetrate
    • infected cells and stop viral replication.
    • Olive leaf can stimulate a process called phagocytosis, an immune system response in which cells act like little Pac-Man, ingesting harmful microorganisms and foreign matter.

    In vitro studies have found olive leaf extract is effective against over 50 common disease causing organisms including viruses, bacteria, fungi and protozoa such as herpes, influenza A, Polio 1, 2, and 3; Salmonella typhimurium, Candida Krusei and Coxsackie A21.

    Biochemist Arnold Takemoto, talking to the Townsend Newsletter for Doctors and Patients put it this way: “(I have) yet to discover another herbal substance that accomplishes antimicrobially what this substance achieves.”

    But not just any old olive leaf…

    One brand I particularly like is Barlean’s olive leaf complex. It’s made 100 percent from fresh-picked leaves; it’s never reconstituted, it has no artificial preservatives, no added sugar and it comes in a fast-acting, great-tasting liquid. Every batch has been thoroughly analyzed using High Performance Liquid Chromatography (HPLC), the global standard to scientifically identify and measure the healing compounds in herbal medicines. In Australia, consumers already spend up to three million dollars a month on this incredible olive leaf product.

    Barlean’s olive leaf complex comes from trees that have been farmed naturally on virgin land in Australia. Organic vermiculture (worm created) fertilizers and pristine irrigation water are coupled with early morning harvesting and immediate transfer of the freshly harvested leaves to the processing plant.

    What dosage is best?
    Though there is really no “official” recommended dose for taking olive leaf complex, many experts recommend a basic maintenance dose for general use and a “therapeutic” dose for special cases. Generally, the consensus is one tablespoonful (15ml) one to two times a day taken right before eating is ideal for maintenance.

    For conditions such as the common cold, flu, sinus infections and basic respiratory tract infections, the recommended dose is 2 × 5ml teaspoons every six hours, says naturopath Jack Ritchason, ND. For acute infections such as sore throat, swollen glands or fever, Ritchason recommends three teaspoons (15ml) every six hours.

    On a personal note, I take a capful of olive leaf complex on a daily basis as a general tonic and immune system booster. Although this is hardly a scientific statement, I can tell you I rarely get sick and on the few occasions I do, it’s very mild and I’m back to my routine in record time. Apparently, I’m not alone in being a fan of olive leaf complex. Experts agree taking this wonderful supplement can be a valuable part of anyone’s health routine.

    Says Ritchason: “From all indications—research, case studies and widespread use—olive leaf extract appears to be an extremely safe supplement that can effectively aid the body in improving immune function and fighting infection by various microbes.”

  • Most people contract one or more colds every year. A cold is caused by viruses that infect cells of the upper respiratory tract. Since there are over 200 different species and strains of these viruses, a cold caused by one virus does not protect a person from catching a cold cause by a different one. This explains why colds can occur one after another or several times a year. An acute sore throat, on the other hand can be caused by a viral or bacterial infection. If your sore throat gets worse no matter what you do, it’s probably bacterial and may require a trip to the doctor for an antibiotic. The well-known symptoms of a cold include stuffy nose, watery eyes, low fever, aching, and possibly a sore throat.

    Conventional medical treatment for a cold generally involves rest, aspirin, decongestants, and drinking a lot of fluids. Conventional medical treatment for a sore throat also involves rest, aspirin, lots of fluids, and sometimes antibiotics. An integrative approach may also include supplementation with vitamin C, zinc lozenges, Echinacea, vitamin A, and a homeopathic remedy for colds.

    Vitamin C
    Since the late, great Nobel Laureate, Linus Pauling first discussed that megadoses of vitamin C might be an effective treatment for the common cold, the medical world has published study after study attempting to prove or disprove Pauling’s claim. In some cases, the studies were flawed since the amounts of vitamin C used were hardly megadoses, and were not sufficient to elicit a response.

    Placebo-controlled studies have shown that vitamin C supplementation decreases the duration and severity of common cold infections. However, the magnitude of the benefit has substantially varied, hampering conclusions about the clinical significance of the vitamin. In one published review, 23 studies with regular vitamin C supplementation were analyzed to find out factors that may explain some part of the variation in the results. It was found that on an average, vitamin C produces greater benefit for children than for adults. Perhaps of greatest significance, the dose also affects the magnitude of the benefit, there being on average greater benefit from at least 2000 mg daily compared to 1000 mg daily. For example, in five studies with adults administered 1000 mg daily of vitamin C, the median decrease in cold duration was only six percent, whereas in two studies with children administered 2000 mg daily, the median decrease was four times higher, 26 percent. The studies analyzed in this review used regular vitamin C supplementation. The authors of the review, however, noted that, “it is conceivable that therapeutic supplementation starting early at the onset of the cold episode could produce comparable benefits.”1

    In fact, this is exactly what took place in a recent study involving 252 adult subjects with a cold or flu who were treated with hourly doses of 1000 mg of vitamin C for the first six hours, and then three times daily thereafter. A control group of 463 subjects were treated with pain relievers and decongestants. The results were that overall reported flu and cold symptoms in the vitamin C group decreased 85 percent compared with the control group after the administration of megadose Vitamin C. The researchers in this study concluded: “Vitamin C in megadoses administered before or after the appearance of cold and flu symptoms relieved and prevented the symptoms in the test population compared with the control group.”2

    I’ve also found effective results with the common cold when supplementing with higher doses of vitamin C. I recommend 1000–2000 mg every two hours (reduce dose if experiencing loose bowels).

    Zinc Lozenges
    Zinc’s role in immune function is well established.3 The use of zinc in a lozenge form for the treatment of the common cold is also gaining validity. In one randomized, double-blind, placebo-controlled clinical trial, the treatment of the common cold with zinc lozenges resulted in a significant reduction in duration of symptoms of the cold. The zinc group had significantly fewer days with coughing, headache, hoarseness, nasal congestion, nasal drainage, and sore throat. Cold symptoms were over in 4.4 days in the zinc group compared with 7.6 days in the placebo group.4

    Echinacea
    Echinacea is an immune stimulant/supporter, and is excellent in the prevention and treatment of colds and influenza. Research suggests that Echinacea supports the immune system by activating white blood cells (lymphocytes and macrophages).5 In addition, Echinacea appears to increase the production of interferon, which is important to the immune response of viral infections.6 In any case, a number of double-blind, clinical studies have confirmed Echinacea's effectiveness in treating colds and flu.7,8,9,10,11 However, some research suggests that Echinacea may be more effective if used at the onset of these conditions.12,13

    In addition, the results of a published study involving 238 subjects confirmed that Echinacea was safe and effective in producing a rapid improvement of cold symptoms. In the subgroup of patients who started therapy at an early phase of their cold, the effectiveness of Echinacea was most prominent.14 In a similar study, 246 subjects with a cold were treated with Echinacea preparations or a placebo. Those treated with the Echinacea preparations experienced a reduction of symptoms, significantly more effective than the placebo. The researchers concluded that the Echinacea preparations, "represent a low-risk and effective alternative to the standard symptomatic medicines in the acute treatment of common cold." 15

    Homeopathic Remedy For Colds
    In one clinical study, 170 soldiers suffering from the common cold were treated with either a combination homeopathic preparation, or aspirin. On the 4th and 10th treatment days, both the homeopathic remedy and the aspirin were found to possess comparative effectiveness in the treatment of the common cold.16 Another study involving 53 outpatients suffering from common cold found similar results.17

    Vitamin A
    Vitamin A's role in maintaining healthy epithelial tissue helps to fight infection by preventing the invasion of bacteria or viruses. In addition, children with even mild vitamin A deficiency develop respiratory infections and diarrhea at two and three times the rate of children with normal vitamin A status.18
