Chaga is a slow growing fungus which grows on birch trees (and is also on alder and beech trees). Geographically, Chaga is restricted to cold habitats, found growing in Russia, Korea, Eastern and Northern Europe, northern areas of the United States, and in Canada.
Why are mushrooms considered to be a fungus?
Mushrooms are considered a fungus, or a member of the fungi kingdom, as they do not contain chlorophyll, yet they have a strong symbiotic relationship with other plants and organisms – growing on decomposing leaves, logs, trees and soil in a forest setting; fungi are essential to our food chain. Fungus have the ability to break down organic matter in a decaying forest and actually draw its food and nutrients directly from decaying trees, rather than from the soil itself. Fungi digest their food outside their bodies by releasing enzymes into the surrounding environment, breaking down organic matter into a form the fungus can use.
Mushrooms are the fruiting bodies produced by some fungi and the term “mushroom” applies to those fungi that have a stem, a cap, and gills or pores on the underside of the cap.All fungus begins with a spore which germinates, when the spore grows strands, this is called the mycelium. The fruiting body or the visible top of the mushroom, and the mycelium (the feeding body) make up the mushroom which can appear to grow overnight, in the cases of some species, or take longer time for development in other species.
In the case of Chaga, its sterile conk – a perennial woody growth, which is the mycelium of the mushroom – has the appearance of a black, irregular, cracked mass resembling burnt charcoal that grows on tree trunks. Due to the large amounts of melanin present in the chaga mushroom, the fruiting body rarely is seen. Unlike most mushrooms, chaga is a polypore, a fungus with pores instead of gills. Rather than growing in soil, Chaga prefers birch trees, once a tree is dead, the “sterile conk trunk rot of birch”, referring to chagas fruiting bodies grows under the outer layers of wood surrounding the sterile conk, spreading its mushroom spores for regrowth.
Chaga is also known as siberian chaga, clinker polypore, cinder conk, black mass, birch canker polypore, sterile conk trunk rot of birch and birch mushroom. In the arctic, the first nation’s people used chaga as a form medicine and called it Tiaga or Tsa Ahga. In France, it is called the carie blanche spongieuse de bouleau (spongy white birch tree rot), the Dutch name is berkenweerschijnzwam (birch mushroom glow) and in Germany it is known as Schiefer Schillerporling (slate inonotus). However in the Orient, Chaga is known as “King of the Herbs” a name which most alludes to its respected and powerful healing properties.
History of this Medicinal Plant
A healing plant of renowned value throughout the world, Chaga is thought to be one of the strongest immune stimulating medicinal mushrooms and is used today as the base natural product in over forty oncology pharmaceutical medications and compounds. Since the early 16 th century, Chaga has been documented for its medicinal actions. Traditionally Chaga was used as a common remedy for cancer, gastritis, ulcers and other toxic diseases; especially for tumors of the stomach, esophagus, lungs, genital organs and/ or breast.
- Beta-D-glucans, a type of polysaccharide which has strong anti-inflammatory and immune balancing properties, reputed to assist in stimulating the body to produce natural killer (NK) cells to battle infections, tumor growth and stimulate apoptosis (programmed cell death). The 3-beta-D-glucans found in medicinal mushrooms have been subject of research since the 1960s.
- Phenolic compounds, melanins
- Lanostane-type triterpenoids, including betulin and betulinic acid. (The anti-cancer properties of betulin or betulinic acid are currently being studied for use as chemotherapeutic agents and are already used as anti-HIV agents in mainstream medicine). Important note: betulinic acid appears to be absent in cultivated chaga, with nature herself producing higher medicinal quality chaga.
- Bitter triterpene compounds that support the thymus and spleen,
- Germanium: one of the highest sources found in nature.
Reputed Health Benefits
Studies support the use of Chaga for immune enhancement, possible cholesterol lowering, anti-obesity properties and improved insulin resistance, digestive tonic, anti ulcer, general tonic, psoriasis, diabetes, hypertension, anticancer potential, an anti viral, anti tumor, immune response modifier, (may assist in the modulation of T-Cells, macrophages, neutrophils, and white blood cells), anti-inflammatory properties, hypoglycemic activities and antioxidant properties offering protection against oxidative damage to cellular DNA.
Much research has been conducted in Russia on this remarkable adaptogen fungus and more recently, health advocate David Wolfe can be found on”You Tube” educating his listeners on Chaga mushroom as a super food used daily for overall health enhancement. Chaga may help to:
- Support and enhance immune function and help improve resistance to dis-ease. Chaga also contains the full spectrum of immune-stimulating phytochemicals found in other medicinal mushrooms.
- Adaptogen properties: help the body to respond and resist internal and external stressors
- Reduce fatigue, improve vitality, endurance and stamina
- Regulate digestion: a useful anti-inflammatory agent of benefit for gastritis, ulcers and general pain.
- Improve mental clarity
- Improve physical performance
- Antioxidant and anti-aging effect
- Regulate the function of muscles and nerves
- Improve resistance to disease
- Enhance sleep quality
- Improve metabolism
- Regulate the activity of cardiovascular and respiratory systems
- Reduce pain
- Promote healthy skin and hair
- Contains antioxidant properties
- A restorative tonic and blood cleansing agent
- Contains anti viral, anti fungal and anti tumor properties.
Interesting Tidbit: Siberian Chaga is neither a plant nor animal yet its DNA make up is thirty percent closer to humans than plants.
Nature vs. nurture
Chaga is best used medicinally when harvested through wild crafting, as the mushroom holds the highest medicinal value and chemical constituents when wild crafted; the cultivated species are lower (or absent) in both medicinal properties and betulinic acid. Chaga can be purchased here in dried form and prepared as a tea. To purchase Chaga Mushroom:
Other Medicinal Mushrooms
One important clarification, medicinal mushrooms do NOT include the common white, brown mushroom or button mushroom – those common edible mushrooms found in supermarkets. White or button mushrooms have little flavor and no medicinal value compared to wild species. In fact, they may even be unhealthy -heavily sprayed with malathion and other pesticides and provide no nutritional value. The medicinal mushrooms include: Reishi, shitake, chaga, turkey tail, maitake, agaricus, oyster mushrooms, coriolus, cordyceps, poria which contain immune enhancing benefits.
