Colloquially known as Black Gold or the Forest's Diamond, the chaga fungus's various monikers conjure up images of radiant gems and threads of precious metals adorning trees. However, in reality, chaga is a parasitic growth on the trunk of the boreal birchK, resembling a large, black chunk of bark more than a typical mushroom.
Despite its unassuming appearance, this is indeed a fungus – and one that carries a formidable reputation, or at least an increasingly fashionable one. Chaga has a longstanding history of use in Russia and parts of Asia, where it's been leveraged for millennia as a treatment for numerous health conditions. However, its adoption in Western societies is a comparatively recent phenomenon. This newfound popularity is particularly evident in Alaska, a region with a rich culture of foraging for both food and medicinal purposes. Given the prevailing sentiment, Alaskan chaga may be the forest's most potent natural remedy, if the escalating buzz around it holds any merit.
An individual known as Callen Troy Christensen, CEO of Fairbanks' Chaga Co-operative, is one of the locals who knows everything there is to know about mushrooms. At a local farmer's market in Fairbanks, Alaska, Christensen can be seen offering small cups of chaga tea, reminiscent of lightly brewed coffee, to interested passers by. His stand is filled with wooden bowls overflowing with an array of mushrooms and fungi, featuring various shades of grey and brown, with textures that range from delicate and dense to rippled and smooth. On one end of the display, an intriguing pile of lumpy black and orange nuggets labelled "Chaga" catches the eye of many visitors.
This unique fungus, which is native only to boreal birch forests in the northern hemisphere, holds a prominent place in Alaska's dense forests. For those daring enough to venture into these woodlands, chaga can be discovered growing as woody conchs on living birch trees. Essentially a mass of mycelium fungus (the fungus's root structure, whereas mushrooms are the reproductive, fruiting body), it takes chaga around 20 years to mature into a grapefruit-sized chunk that's large enough to harvest.
The majority of commercially accessible chaga is typically pulverized into a fine powder and packaged into K, infused into tea bags, or blended into energy-boosting supplements. However, in the local markets and boutiques of Alaska, where indigenous foragers and healers promote the marvels of chaga, newcomers can engage in a more tactile process of preparation. This involves a prolonged steeping in water that's heated below boiling point, resulting in a nutrient-packed tea with an aroma reminiscent of earth and vanilla. Chaga can also be procured in the form of an alcohol-based tincture, to be utilized as a tonic, supplement, or herbal remedy.
Chaga has been a part of human history for hundreds of years. It's believed that inhabitants from Russia and Siberia may have been the first to exploit chaga for its therapeutic properties. Reportedly, Tsar Vladimir Monomakh used it in the 12th Century to treat his lip cancer. References to chaga as a remedy for conditions such as cancer, ulcers, and tuberculosis appeared in medical documents as far back as the 16th Century. Additionally, during the second World War in Finland, a sweet chaga-based beverage gained popularity as an alternative to coffee, used to enhance energy and focus during a scarcity of coffee and sugar.
The indigenous communities of Alaska have a storied tradition of foraging and harnessing the healing power of nature. While many specifics have been clouded by colonization, oral narratives and stories about chaga's use have been perpetuated over generations and preserved by tribal elders. As Jon Ross, a Culture Bearer for the Salamatof Tribe of the Dena'ina Athabascan people, stated, "Having lived outdoors for millennia, every element of nature was crucial for survival. Nature was our apothecary. It was ingrained in our daily life."
The residents of Alaska maintain a strong tradition of foraging. Depending on the season, they can be seen strolling along trails, venturing into the woods, or exploring the state's hillsides, carrying a bucket or basket in search of blueberries, fireweed, or fungi. "Alaska has a long history of being a society of hunters, gatherers, and foragers; it's kind of our trademark," remarks Kate Mohatt, an ecologist for Chugach National Forest and the initiator of the Turnagain Arm Mycological Society.
Yet, it has only been within the past decade that chaga has broken through to mainstream recognition in broader Western societies, earning the title of a medicinal "superfood".
Supporters, foragers, and advocates of alternative medicine proclaim this fungus as a potential universal remedy for a range of ailments, from cancer to the common cold. However, to date, scientific evidence supporting these assertions is limited. While animal and in-vitro studies have produced promising results in the fields of cancer, inflammation, and immunity, human studies remain sparse, reducing chaga's status to that of an unverified folk medicine.
The universal healing properties attributed to this fungus may remain a matter of debate, but its rich nutritional value is less contentious. It boasts a wealth of vitamins, minerals, and nutrients, including high quantities of antioxidants, plant sterols, and amino acids. According to Kayla Hegna, co-proprietor of Artic Chaga,"It's packed with vitamins and minerals that are necessary for our daily health upkeep,".
The chaga, essentially a parasitic organism residing on the birch tree, consumes these nutrients, concentrates them, and renders them more bio-available for human absorption - a remarkable gift from nature.
Chaga relies on frigid conditions for its growth, with more extreme temperatures yielding better results. Interestingly, the more drastic the seasonal temperature fluctuations and the greater the stress experienced by the birch tree, the richer the nutrients in the chaga. This makes Alaska, known for its temperature extremes exceeding 32C (90F) in summer and dropping below -45C (-50F) in winter, an optimal natural habitat. As a result, this region may boast some of the world's most potent chaga, making it an ideal location to acquire this local fungus. According to a test commissioned by Arctic Chaga, the local chaga exhibited an antioxidant count nearly 40% higher than a Siberian variety.
Moreover, Alaska may also lead in the most sustainable harvesting practices of this medicinal fungus. According to Christensen, "a large part of the market is currently supplied by Russian logging firms, where chaga is essentially a by-product of clearing the boreal forest,". Meanwhile, other prominent brands tend to procure their supplies from countries like China in bulk.
In contrast, in Alaska, the chaga is hand-foraged by small, frequently family- or community-owned entities, who are cautious to avoid over-harvesting. With little research available on chaga's reproductive cycle, many foragers are conscious that excessive harvesting could be harmful to the fungus. This is why organizations such as the Chaga Co-operative are investing in long-term research, while local vendors process it on a small scale to maintain quality.
Furthermore, many Alaskan sellers offer educational foraging tours and workshops. At farmers markets and local stores, they distribute samples and respond to queries, providing visitors the opportunity to savor, touch, and see that the wonders of Alaska's natural landscape are truly worth discovering.
In the radiant tapestry of natural remedies, Chaga mushrooms, Alaska's 'Black Gold', is emerging as a star player, capturing the curiosity of the Western world. Celebrated for its potent nutritional profile, Chaga's deep roots in traditional medicine are now entwining with modern wellness trends, sparking a renewed appreciation for nature's pharmacy.
The future of Chaga and other functional mushrooms as a supplement or medicine is looking bright!!!
