Diatomaceous Earth

    A light friable siliceous material derived chiefly from diatom stays and used specifically as a filter. [1]


    Diatomaceous earth is a type of powder made from the sediment of fossilized algae found in bodies of water. Since the cells of these algae were high in a compound called silica, the dried sediment produced from these fossils are also very high in silica. These deposits are discovered all over the world. The ancient greeks used diatomaceous earth to make building materials, like bricks and blocks. Later on it became popular in europe for numerous commercial usages.

    When taken by mouth, diatomaceous earth is used as a source of silica, for dealing with high cholesterol levels, for treating constipation, and for improving the health of skin, nails, teeth, bones, and hair.

    When applied to the skin or teeth, diatomaceous earth is used to brush teeth or eliminate unwanted dead skin cells.

    Diatomaceous earth is also used in industry. It is utilized to eliminate undesirable material from drinking water. It is also utilized as a filler or to prevent formation of lumps in foods, medicine, paints and plastics, and pet litter. It is used to tidy up spills or for insulation in industry, along with to scrub things. Diatomaceous earth is used as part of different chemical tests. It is also used as an insecticide. [2]


    Diatomaceous earth, which was first thought to be a type of limestone, was found around 1836-1837 by peter kasten while drilling a well in hau├čelberg hill which lies in l├╝neburg heath in germany. After its discovery, it was used by alfred nobel to make dynamite and also by wilhelm berkefeld for developing filter candles. [3]


    Each deposit of diatomaceous earth is different, with varying blends of pure diatomaceous earth integrated with other natural clays and minerals. The diatoms in each deposit contain various amounts of silica, depending upon the sedimentation conditions, on the presence of other sediments (clay, sand, asheses), and on the age of the deposit (diagenesis, silica dissolution/precipitation, diatoms tests ageing). The species of diatom might also differ among deposits. The types of diatom depends on the age and paleo environment of the deposit. In turn, the shape of a diatom is determined by its species.

    Numerous deposits throughout british columbia, such as red lake earth, are from the miocene date and include a types of diatom referred to as melosira granulata. These diatoms are around 12 to 13 million years old and have a small globular shape. A deposit containing diatoms from this epoch can supply specific advantages over others. For example, diatoms from the eocene epoch (roughly 40 to 50 million years old) are not as reliable in their capability to take in fluids due to the fact that as older diatoms recrystallize, their small pores ended up being filled with silica. [4]

    How does diatomaceous earth work?

    The insects’ body fluids leakage out and within a short time this loss of fluid causes them to pass away of dehydration. Diatomaceous earth can act internally, too. When pest consume de, it takes in the fluids in their bodies, likewise causing dehydration that kills them. For insecticide purposes, the diatom shells are pulverized into a dust so that it will quickly cling to pest bodies. Diatomaceous earth is deadly to pests due to the fact that its minute dust particles are razor sharp and act like fragments of damaged glass, lacerating and piercing the insects’ bodies. The injuries end up being deadly as vital fluids drain out, and the bugs rapidly pass away. [5]

    Ranges of diatomaceous earth

    Food-grade and filter-grade varieties

    silica exists in 2 primary forms, crystalline and amorphous (non-crystalline).

    The sharp crystalline kind looks like glass under a microscope. It has properties that make it desirable for numerous commercial applications.

    The two primary kinds of diatomaceous earth differ in their concentrations of crystalline silica:.

    Food grade: this type consists of 0.5– 2% crystalline silica and is utilized as an insecticide and an anti-caking representative in the farming and food industries. It is approved for usage by the epa, usda, and fda.

    Filter grade: also known as non-food-grade, this type contains upwards of 60% crystalline silica. It is harmful to mammals however has many commercial uses, consisting of water filtration and dynamite production. [6]

    Color and types

    The different colors of diatomaceous earth show the regional distinctions of diatomite deposits from all over the world. Varying in color from light grey to brown to white, diatomaceous earth is graded by the pureness of silica and the amounts of other minerals. For ‘food grade’ de, there must disappear than 10mg/kg of lead or arsenic.

    The diatomaceous earth discovered on the retail market is available in two types, swimming pool grade and food grade. Pool grade is calcined or treated with high heat, which turns the silica dioxide into crystalline silica. This procedure highlights the filtering qualities of de but makes it very hazardous to the respiratory systems.

    Food grade diatomaceous earth is a freshwater kind of diatomite. Although it can trigger minor lung irritation over long direct exposure, it’s safe to utilize topically and is frequently taken as a health supplement. Property owners and garden enthusiasts might be more knowledgeable about food grade de because it’s low-cost and an essential tool in numerous pest management methods. [7]

    Benefits of diatomaceous earth

    Diatomaceous earth (d.e.) Is a naturally taking place soft, sedimentary rock made from the fossilized remains of tiny aquatic animals called diatoms, which are a group of algae.

    The skeletons of these unicellular organisms are made from silica and have built up in the sediment of rivers, streams, freshwater lakes, and oceans all over the world for hundreds of thousands to countless years. These silica-containing deposits are mined for both commercial and food-grade usage.

    What is silica?

    Diatomaceous earth is a concentrated source of silica. Also referred to as silicon dioxide, silica is frequently found in nature in quartz, clay, sand, and living organisms. silica is highly searched for commercial and industrial use, in addition to its possible health advantages.

    If the concept of consuming silica sand for health seems hard to swallow, keep in mind there stand out differences between filter-grade and food-grade diatomaceous earth. Filter-grade d.e. Contains hazardous quantities of silica harmful to mammals and is mostly for commercial use. It can be specifically dangerous to people when inhaled.

    Food-grade d.e., nevertheless, is purified and is usually recognized as safe for both people and animals by the u.s. Food and drug administration (fda). In addition, food-grade d.e. Might have some health advantages for human beings such as reduced bad (ldl) cholesterol, relief from irregularity, and improved nail and hair health, however there is insufficient clinical research study to support these claims.

    Talk with your physician prior to taking d.e. Supplements to assist treat a health condition because many claims about the product have not yet been confirmed in medical settings.

    Health advantages

    Marketing for diatomaceous earth supplements makes some quite considerable health claims. However, health claims for dietary supplements are uncontrolled by the fda, which suggests there is no guarantee of safety, effectiveness, strength, or purity of any supplement, including d.e.

    Because of the lack of evidence-based nutrition research, it’s not advised to take d.e. Supplements at this time. However there are other ways to improve your consumption of silica by taking in particular foods and beverages including this mineral.

    silica is a mineral that’s essential to the formation of collagen in your body, however rather than taking a d.e. Supplement, nutrition professionals advise picking foods that are high in silica such as:.

    • Bananas and dried fruit
    • Beans (certain types)
    • Beer and red wine (in small amounts)
    • Dairy and meat products
    • Green beans
    • Mineral and sparkling water
    • Nuts and seeds
    • Oats
    • Rice
    • Tea and coffee
    • Wheat

    Health claims

    There are a variety of anecdotal claims that food-grade diatomaceous earth provides health benefits. But the most significant issue about these claims, according to ginger hultin ms rdn cso, a representative for the academy of nutrition and dietetics, is the lack of inadequate and trustworthy evidence concerning the safety of using this product. Here’s a closer take a look at a few of the health claims.

    Body cleansing

    Proponents state that d.e. Can eliminate toxins and heavy metals from the intestinal tract to “detox” the body. Filter-grade d.e. Is an industrial-grade filter that removes heavy metals from water, however this “cleaning” result has not been proven in humans with food-grade d.e. In general, most health professionals do not endorse products with health claims promoting detoxing and cleaning.

    Enhanced digestion

    The “detoxifying” properties of d.e. Claim to clear out the colon, which advocates state will improve gastrointestinal function and promote regularity by increasing the frequency of bowel movements.

    Bone health

    silica is found in trace quantities in connective tissues throughout the human body, so some people think it helps with the healthy aging of the bones and joints. Because d.e. Is made almost completely of silica, which is essential for cartilage development, some claim that the item assists to reinforce bones and joints also. Emerging research on silicon and bone health is promising however stays uncertain.

    Improved hair, skin, and nails

    Supporters claim that silica can likewise enhance the skin, hair, and nails. silicon dioxide is likewise found in numerous hair items. Some people have said that d.e. Supplements can produce fuller, thicker, much healthier hair within a few weeks of routine usage. Similarly, it is stated that silica helps with collagen production to improve skin texture and look and may likewise reinforce nails.

    Increased energy

    Anecdotal claims report that taking d.e. Supplements during the day can increase your energy levels, but again, there is no evidence to support this.

    Reduced swelling

    Proponents have said that d.e. Supplements can assist fight inflammation in the body. While there is no evidence to back this claim, some research study has actually shown the inverse. A 2015 follow-up study of diatomaceous earth workers who breathed in extreme amounts of silica revealed increased inflammation and circumstances of lung disease.

    Weight loss

    Research on diatomaceous earth for weight-loss is unclear at this time. There have been some studies about taking it to help lower cholesterol (ldl and triglycerides), but bigger, more rigorous studies are still needed to better comprehend the security and effectiveness of using d.e

    . The bottom line is that health claims for taking diatomaceous earth are primarily theoretical because not enough human studies have actually been performed. [8]

    How to utilize it

    You may have wondered, “is diatomaceous earth harmful or healthy for people?”

    Diatomaceous earth is safe for people and animals to take in, and it’s also advantageous for skin, so it’s utilized both within and outside the body. Simply be sure to inspect the source, and make sure your item is food-grade. Skip utilizing internally if it is not.

    The u.s. Fda lists food-grade diatomaceous earth as “generally recognized as safe,” which indicates that it’s legally allowed to be contributed to several types of foods, beverages and supplements. Small amounts of silica are usually present in all body tissues and normally found in urine, too, so it’s well-tolerated and not known to cause many side effects.

    What is diatomaceous earth used for? De items have actually been utilized for years on the outside of structures, on farms, in gardens, and in human and pet foods.

    In addition, today there are over 150 pesticide-related products signed up for usage both inside your home and outdoors which contain de. There are likewise thousands of non-pesticide, food-grade diatomaceous earth products that are used on the skin, in food, in items for animals, and in supplements or medications.

    There are a number of methods to use de. A few of the most popular diatomaceous earth uses include:

    • Pet nutrition items
    • Products utilized on animals like pet dogs and cats to kill fleas
    • Bed bug-killing treatments
    • Sprays and items utilized for pest control, consisting of cockroaches, crickets, fleas, ticks, spiders
    • Rodent sprays

    Negative effects of diatomaceous earth

    There is insufficient dependable details to figure out if diatomaceous earth is completely safe. Scientists have actually not concluded any guaranteed side effects. However, inhaling it may cause extreme breathing problems, particularly if the client already has respiratory problems. For example, it might get worse conditions like asthma and chronic obstructive lung illness (copd). The supplement is likewise extremely abrasive, so it may cause inflammation and injuries on the skin as a topical. [11]


    Diatomaceous earth is enriched with minerals and naturally happening silica and supplies a range of unbelievable advantages. At diatomaceous earth online, we provide food, animal and bug grade de of high quality. If you are searching for diatomaceous earth dosage, the following guide can help you get a concept about the advised quantities. [12]

    Unique preventative measures and warnings

    Pregnancy and breast-feeding: there is inadequate reliable details about the security of taking diatomaceous earth if you are pregnant or breast feeding. Remain on the safe side and avoid usage.

    Lung illness: some types of diatomaceous earth might be damaging to the lungs, specifically if breathed in. Breathing in diatomaceous earth might result in lung problems in people that currently have some issues in their lungs. This consists of asthma, chronic obstructive pulmonary illness (copd), etc. Use very carefully. [13]


    The requirement to slowly withdraw from the chemical-based pesticide policies to more sustainable and environmental approaches is, at today, one of the most challenging elements of bug management. The existing reduction in the registered pesticides will unquestionably continue, increasing at the same time the need to establish unique, reliable but also environmentally compatible compounds. On the other hand, the introduction of a brand-new pesticide is a pricey and long process, making the total overdrawn from the standard protectants an impractical circumstance. Hence, inert dusts such as des might have an essential role to play in future pest management techniques, making sure an abundant supply of safe and healthy food and feed. Des hold fantastic prospective as carriers of typical insecticides, reducing the required application doses of the latter. In addition to synergistic impacts, integrated applications might likewise reduce the negative impacts of the compounds and can be more suitable with the preferred criteria for food safety and protection of human health and the environment. Nevertheless, the intro of other representatives must be constantly evaluated under the prism of the possible unfavorable results they might hold, such as for instance the adoption of entomopathogenic fungi agents. However, the application of insecticides and acaricides with a various mode of action might be a service for the control of resistant arthropod populations, which is a hot topic in modern integrated pest management. Although there are lots of data for their insecticidal and acaricidal residential or commercial properties, little progress has actually been made regarding the optimum processing of de dusts used as insecticides and acaricides. Today, the majority of commercial de formulations are prepared through a basic procedure of quarrying, drying, and crushing the mined heterogeneous rocks. This simplified treatment leads ultimately to formulas with excellent variability in their physicochemical qualities, affecting concurrently their insecticidal/acaricidal properties however also some properties of the commodity itself. For that reason, more particular approaches of processing should be discovered to standardize the production of dusts bearing the most desirable functions for increased insecticidal effectiveness.

    Application techniques and systems of des are also a concern of major significance, needing extra examination. Even with the present de formulations, various application methods, such as utilizing slurries or dealing with only partial layers of the food, must be checked out. Therefore, research study should be carried out under a variety of food-handling facilities to design efficient protocols for pest management however likewise to figure out the effects of sanitation on the performance of de dusts. Such real-scale applications may highlight the potential of des and explore ways of incorporating de applications within the total pest/vector management program in food market, agricultural and city settings.

    The data from laboratory studies highlight the insecticidal and acaricidal value of des under a wide range of arthropods. More analysis must be conducted toward this direction not only to determine all the target species but also to investigate the general result of des in non-target species. Undoubtedly, by examining the existing literature, we observed that non-target impacts of de have actually been assessed just on a restricted variety of natural opponents of crop pests, with special referral to aphidophagous coccinellids, lacewings, anthochorids, and phytoseiidae termites, showing restricted consequences for these essential biocontrol representatives. In this appealing circumstance, further research should be committed in comprehending the possible non-target effects of de-based formulas. [14]
