Xenca Five a Day +

Rich in Concentrated Green Foods

Xenca 5 A Day + is very rich in concentrated green foods grown in nature that contain naturally occurring chlorophyll, this is found  in green algae Spirulina, Chlorella, cereal grass juices, alfalfa and sea vegetables Dulse & Kelp.

Barley Grass Juice, Wheat Grass Juice & Kamut Cereal Grass Juice are a particularly rich natural source of chlorophyll, they contain two different types of chlorophyll (chlorophyll a and chlorophyll b) which have been found in clinical studies to neutralise harmful toxins and has undoubtedly caused  many leading health pioneers including the  late Dr. Bernard Jensen, holistic health pioneer and author of Chlorella, Gem of the Orient, to state “Chlorophyll is the greatest natural tissue cleansing agent known to man.”

Naturopath Linda Page, Ph.D., in her book “Healthy Healings Detoxification: Programs to Cleanse, Purify and Renew.” quotes the fact that alkalizing minerals in wheatgrass juice complement the blood-cleansing effects of chlorophyll, helping to reduce inflammation and other ill effects caused by overly acid conditions.

A recently completed study by Linus Pauling Institute investigator Professor George S. Bailey showed that chlorophyll was effective at blocking or neutralising uptake of a harmful toxin, aflatoxin-B1 in humans, using accelerator mass spectrometry to track an ultra-low dose of the carcinogen (C Jubert et al., manuscript submitted – awaiting publication).

However there are other clinical studies showing that natural chlorophyll inhibited AFB1-induced liver cancer in animals (1). Clinical studies also show that chlorophyll is also able to form tight molecular complexes with certain chemicals known or suspected to cause cancer, including polycyclic aromatic hydrocarbons found in tobacco smoke (2), some heterocyclic amines found in cooked meat (3), as well as aflatoxin-B1 (4). The binding of chlorophyll to these potential carcinogens may interfere with gastrointestinal absorption of potential carcinogens, reducing the amount that reaches susceptible tissues (5). After studying the clinical research it seems logical that high chlorophyll foods like Wheat, Barley and Kamut would have cleansing and neutralising properties.

In 2005, a group of German researchers published a study in the journal Carcinogenesis, showing that chlorophyll supplementation seemed to be good for the colon. According to the researchers, it seemed that chlorophyll may block the absorption of its look-alike molecule, heme, in the colon, helping to keep the colon walls smooth and healthy.[6]

Interestingly enough, chlorophyll is very similar in structure to the pigment that allows our blood to transport oxygen, heme. Both of them contain a specific chemical structure called a porphyrin ring. In the centre of chlorophyll’s porphyrin ring is a magnesium atom. In the middle of the heme’s ring is iron. It seems likely that chlorophyll can be absorbed into the body’s lymphatic system, cells and tissues because of its remarkable similarity to haemoglobin, the compound that carries oxygen in the blood.

Dr. Yoshihide Hagiwara, president of the Hagiwara Institute of Health in Japan, is a leading advocate for the use of grass as food and medicine. He reasons that since chlorophyll is soluble in fat particles, and fat particles are absorbed directly into the blood via the lymphatic system, that chlorophyll can also be absorbed in this way. In other words, when the “blood” of plants is absorbed in humans it is transformed into human blood, which transports nutrients to every cell of the body. This may help to explain why there is a cleansing action that is often spoken about with cereal grass juice powders.

Of course the similarity between chlorophyll and heme doesn’t mean that you can just switch them out for each other and make new blood cells. But long-overlooked preliminary research and some more recent case study reports indicate chlorophyll-rich foods and chlorophyll extracts may help increase red blood cell count significantly.[7] [8]

Clinical studies also show that Chlorophyll can neutralize several physically relevant oxidants (reactive oxygen species )in vitro (9, 10), and limited data from animal studies suggest that chlorophyll supplementation may decrease oxidative damage induced by chemical carcinogens and radiation (11, 12).

A recent study showed that human colon cancer cells undergo cell cycle arrest after treatment with chlorophyll (13). The mechanism involved inhibition of ribonucleotide reductase activity. Ribonucleotide reductase plays a pivotal role in DNA synthesis and repair, and is a target of currently used cancer therapeutic agents, such as hydroxyurea (13). This provides a potential new avenue for chlorophyll in the clinical setting, sensitizing cancer cells to DNA damaging agents.

It seems clear from clinical evidence that the cereal grass juice powders rich in naturally occurring chlorophyll do have cleansing properties and can neutralise harmful toxins. Furthermore, evidence shows that chlorophyll is fat soluble which means it can be absorbed into the blood via the lymphatic system.
