Wild Siberian Chaga

Wild-Harvested Inonotus obliquus

Clinical Grade 30% Polysaccharide Extract 

This is our Wild harvested Siberian Chaga (Inonotus obliquus) Powdered Extract; ecologically foraged in the arctic forests of Siberia to ensure you the most potent Chaga available. Unlike raw, non-extracted Chaga, this extract is completely digestible and ready to use, with a high degree of absolute bioavailability. With our extract, the indigestible the cellular walls of the mushroom have been broken down to release all the beneficial substances, which have been concentrated and are provided in a ready-to-use form.

Chaga contains some of the highest recorded levels of SOD (superoxide dismutase) and anti-oxidants known. It is used for its regenerative and reparative anti-aging effects and its strong immune enhancing, anti-cancer, anti-tumor, and anti-virus effects. There is a number of laboratory and clinical evidence to support the significant boost to health it provides.

Our Chaga is a dual stage hydroethanolic (hot water and alcohol) powdered extract standardized to contain 30% polysaccharides (approximately a 40:1 concentration). Each 65 gram package of our Wild Harvested Chaga Extract contains the approximant equivalent of over 4 pounds of the whole Chaga--unlocked, bio-available, and ready to use. This concentrated form allows both better absorption as well as a more potent effect. Only the dual stage hydroethanolic protocol provides the most benefit from Chaga, as one of its most potent compounds, betulinic acid, is extracted only with this method.

From the Package

Our Arctic Bear Chaga is crafted with select Siberian Chaga (Inonotus obliquus) that has been wild-harvested in the Arctic. Using a dual-stage, water and alcohol extraction process, Arctic Bear Chaga is standardized to a 30% polysaccharide concentration, resulting in a potent, clinical grade Chaga preparation that delivers the maximum potential of this cherished fungus.*

Wild Harvested in Siberian Forests

Chaga (Inonotus obliquus) is a parasitic fungus which grows primarily on birch trees living in colder regions. It requires the freezing effects of extreme winter. The strongest Chaga grows in forests above the Arctic Circle, which is where ours is harvested in its wild state. We harvest it in the most ideal conditions, from regions affected by the harshest winters in order to assure Chaga of the highest quality and efficacy. One of the most potent compounds found in Chaga, betulinic acid, is formed in the mushroom by extracting its precursor from the bark of birch trees and is found in larger concentrations in colder regions.

chaga extract inonotus obliquus

Amongst the indigenous and traditional people of Siberia and Russia, Chaga is the most renowned medicinal plant or fungi. Traditionally it was prepared and used to enhance the immune system, for its strong anti-tumor effects, and in helping fight infections. Anthropological reports indicate that Chaga has been used to regenerate the endocrine system—an effect of special interest to those interested in androgenic and endocrine /reproductive health.

In traditional medicine systems, Chaga was used primarily as a tonic to strengthen the body and allow it to battle disease and infection. Known by the Siberians as the “Gift from God” and as a “Mushroom of Immortality,” this strange tree growth has been used by humans to support health for a number of centuries. The Japanese call Chaga “The Diamond of the Forest,” while the Chinese classify Chaga as one of the “King of Plants.” It was largely unknown in modern medicine and to most people outside of the cold regions until much later. Russian literature Nobel Prize laureate Alexandr Solzhenitsyn wrote two pages on the medicinal use and value of Chaga in his autobiographical novel, based on his experiences in a hospital in Tashkent.

The RAW Forest Foods Difference

In manufacturing our Chaga Extract, we considered and researched all the available scientific and medical data related to Chaga in order to identify the best available method for extraction and preparation as well as identifying all the benefits it can provide. Across the board, we found that researches used a potent dual stage powdered extract of Chaga (Inonotus obliquus). We especially looked into the specific methods used to make the extracts. Using this information, we selected a similar dual stage, hydroethanolic extraction process for our Chaga Extract (Rhee, S.Y. 2008). This method results in an extremely potent, completely digestible Chaga Extract, where the benefits found in the mushroom have been unlocked and are highly concentrated. This method provides the extract with the highest bioavailability. This means that the beneficial substances found in chaga can be immediately absorbed and used by the body to enhance health.

Most medicinal and supplemental products made from fungus require an extensive boiling process to obtain any possible health benefit. Our Chaga is already extracted for your convenience and ready to use. This is perfect not only for saving time, but also obtaining the most benefits. Our concentrated product in one dose will provide what you'd have to drink gallons of Chaga tea for.

Each 65 gram package of our Chaga Extract requires over 4 pounds of raw Chaga, resulting in roughly a thirty (30) to forty (40) percent standardized concentration of its active compounds, in a unique highly bio-available form.

We developed this Chaga Extract with the simple goal of offering our customers a scientifically backed, premiere preparation. Buying this product guarantees:

  • Ethically and ecologically wild-harvested Chaga fungi for optimum potency;
  • A dual-stage, standardized extract providing a 30% polysaccharide content;

Today's Scientific Research

Laboratory studies on extracts of the Chaga mushroom have indicated a possible potential in cancer therapy, its use as an antioxidant, in immunotherapy, and as an important anti-inflammatory. Chemical analysis shows that Chaga mushroom contains a range of secondary metabolites, including phenolic compounds such as melanins, and lanostane-type triterpenes, which include a percentage of betulinic acid. It is deemed to be one of the most powerful adaptogens.

Chaga has enjoyed ample scientific research into its healing and reparative qualities and is quickly earning its rank as one of the top medicinal mushrooms known. In addition to the unique compounds found in Chaga, it contains some of the highest levels of superoxide dismutase (SOD).

SOD is a naturally occurring enzyme which is used within the health food community to remove wrinkles, rebuild tissue, and extend the length of life. In the clinical setting, SOD is used for treating pain and swelling (inflammation) caused by osteoarthritis, sports injuries, and rheumatoid arthritis. Additionally, SOD is used in healing the kidneys from kidney disease; for clearing gout; and for treating cancer.

In addition to SOD, Chaga has one of the highest levels of antioxidants known (second only to clove bud essential oil), as measured by Oxygen Radical Absorbance Capacity (ORAC). Oxidants are caused by metabolism in the body and are implicated in many diseases of aging, including cancer and cardiovascular disease. Oxidants contribute to DNA mutations, which prevents healthy, normal cell division. They also damage cellular walls, the walls of blood vessels and cause damage to neurons. Antioxidants neutralize oxidants, rendering them harmless and preventing them from causing damage. This keeps the body young. Many customers are surprised when using our Chaga Extract that upon daily use, their fine lines and wrinkles start to fade and disappear. The tissues are repaired and DNA renewed, preventing mutation and cancer as well as other diseases and boosting the immune system.

The Unique Medicinal Compounds

Both SOD and the antioxidants in Chaga enhance the immune system and assist in regenerating the body. But Chaga contains several unique compounds which really drive its ability to protect the body from pathogens and cancer. These compounds are:

  • Betulin and Betulinic Acid: Is a naturally occurring pentacyclic triterpenoid which has antiretroviral, antimalarial, and anti-inflammatory properties, as well as a more recently discovered potential as an anticancer agent. In 1995, betulinic acid was reported as a selective inhibitor of human melanoma (Lee IS, et al. 1995). Also, betulinic acid was found active in vitro against neuroectodermal (brain cancer) and malignant brain tumors, ovarian carcinoma, in human leukemia cells, and malignant head and neck squamous cell carcinoma (Righetti SC, et al. 2002);
  • Inooidiol;
  • Melanin: Is an important pigment in the human body, and its presence protects us from cancer, especially skin cancer, by absorbing the harmful effects of sunlight;
  • Obliquol;
  • Oxygenated Triterpenes;
  • Polysaccharides;
  • Trametenolic Acid: Is an anti-inflammatory sterol, helping combat systemic inflammations and promote the general health of the immune system.

All of the compounds found in Chaga are beneficial and healthy by themselves, but in unison they give additional effects and boost your health in multiple dimensions.

Together, these compounds allow Chaga to strengthen the immune system, better-combating pathogens, including viruses and bacteria. Studies have shown its use to produce a 300% increase in natural killer (NK) cells. Natural killer cells are specialized cells of the immune system responsible for killing cancer and combating viruses. The unique compounds betulin and betulinic acids found in Chaga have been shown to be anti-tumor, prohibiting the growth of tumors. The oxygenated triterpenes in Chaga contribute to its anti-viral and anti-protozoa effects, showing actions against both the HIV retrovirus and the protozoa that cause malaria (Plasmodium). So, chaga not only helps strengthen the immune system by itself, it also helps it perform its function by combating viruses and other infections and pathogens by having the antiviral and antimicrobial action of its own.

The Powdered Extract Advantage

While Chaga contains many highly beneficial compounds, many of them occur in very small amounts (approximately less than 1%) in whole Chaga and are inaccessible in raw and/or non-extracted Chaga. Mushrooms and fungi are composed of a type of long-chain polysaccharide called chitin (pronounced chy-tin). The body lacks the enzymes needed to break down chitin, and this is why many wild mushrooms, while not poisonous, cause severe gastrointestinal distress when consumed (store bought mushrooms have been selected for their digestibility). The nutrients and medicinal compounds in such mushrooms cannot be absorbed unless the cell walls have been broken down. That is exactly what we do here at RAW Forest Foods, to provide our customers with the best possible availability. We also concentrate the product, so the effects are multiplied.

When raw, non-extracted Chaga is consumed, all of the beneficial compounds remain locked away within the chitin. Traditionally, Chaga was broken into smaller pieces and boiled for a minimum of six hours. While this works to release the active compounds, this method of processing does nothing to concentrate the very low levels of beneficial compounds that are naturally occurring in Chaga. It is also impractical for most people.

RAW Forest Foods' Chaga Extract is roughly a 40 times concentration, which brings the 1% active compounds in Chaga up to 40%. Additionally, the unique extraction process used in our extract completely breaks down the chitin in the fungus, resulting in a one hundred percent digestible, completely bio-available Chaga preparation.

It just feels right!

I've been feeling intuitive like my body has needed Chaga for quite some time now and I've always hesitated because the other brands on the market that I've considered buying just haven't felt right for some reason. I bought this for myself recently and felt so incredible even after the first cup (I have it before bed with hot tea). It just feels "right" and I look forward to how it makes me feel daily. I don't have any particular health issues that I bought it for, I've just been very drawn to it I suppose for things going on inside I may not be aware of. I was worried about the taste, but it tastes amazing and mixes into tea perfectly! Highly recommended!

Strongest Chaga Tonic

I've tried using a few different chaga preparations (from several companies I won't mention), including tinctures, capsules, and other powdered extracts. None of them have had such great effects as this extract, and the price is the lowest. The quality is obvious. After taking one teaspoon daily for several weeks, I have had a huge improvement in my immune system already. This is great, because I tend to have a weak immune system. My skin is much nicer, wrinkles seem to be disappearing, perhaps due to the strong ORAC score. Lastly, I feel just a general strength to my endocrine system. More reserve energy, just stronger. I highly recommend this product, just with they would come out with a larger size!
