Chaga mushroom (inonotus obliquus) is prevalent throughout the circumpolar region of the northern hemisphere & has been a powerful component in natural medicine and herbal shamanism for many centuries in places like Russia & Siberia, Northern Europe & Canada/North America. It grows primarily on Birch trees and requires extensive sub zero temperatures in order to proliferate successfully. Unlike most other medicinal mushrooms, Chaga is actually the fungal ‘sclerotia’ rather than the reproductive fruiting body. The sclerotia is a growing mass of fungal cells that stores the reproductive potential of the fungi. As Chaga ages, the nutrient content and concentration of medicinal compounds increases – wild Chaga is generally not considered ‘ready’ until it is at least 15 years old, although the older the better. Chaga is known as a parasitic fungi but has also been observed engaging in a symbiotic relationship with seemingly healthy host trees for many decades.

The vast Siberian wilderness supports the largest population of wild Chaga in the world – much of which is impossible to harvest due to the lack of infrastructure and sheer inaccessibility, making Siberian Chaga a much more sustainable resource than other more fragile, depleted ecosystems. Some researchers have been experimenting with Chaga cultivation and have managed to control Chaga’s development so that it becomes quite large in just a few years, but in reality Chaga develops gradually so only truly aged specimens contain a balanced and complete array of beneficial constituents. Until the science catches up with the need for cultivation, wild Chaga sclerotia is a far superior option, although commercial over-harvesting has become a serious issue in many parts of the world due to increased consumer demand and so a conscientious approach is imperative. Sustainable harvesting practices and restrictions on how much can lawfully be taken are scant although awareness is growing. Nyishar Wild Siberian Chaga Mushroom Tincture is sustainably harvested because there is always intact Chaga remaining on every tree that is harvested from, plus it comes from the most abundant and largely inaccessible Chaga ecosystem that exists. We also place a self-imposed restriction to never exceed 25kg of dried Chaga per year – so no matter how great the demand, we will stop making Chaga tinctures when we have used that amount within a 12 month period.

The production of the concentrated liquid extract (tincture) of wild Chaga uses up dramatically less natural resources than the powdered extract equivalent. It has a level of high potency and takes effect more quickly too due to the fact that it absorbs directly into the bloodstream via the capillaries underneath the tongue. This kind of sublingual administration completely bypasses the need for digestion and means that Chaga’s active constituents are in the bloodstream within a couple of minutes.


Chaga is one of the most powerful ‘adaptogens‘ that we know of in the world today. Adaptogens are known as “biological response modifiers” because they have a normalising effect on metabolism and all biological function. Adaptogens never stimulate or suppress activity in the body regardless of circumstances – they literally ‘observe’ our own, unique inner-terrain in order to see what action is most appropriate. In this way, adaptogens have become widely recognised as one of the most effective long term strategies for dealing with stress and its myriad consequences, not least due to their stabilising effect on the interplay between the sympathetic (fight or flight) and parasympathetic (healing and repair) branches of the nervous system.

There has been a lot of scientific research conducted into the properties of Chaga in Russia, northern Europe as well as China and Japan. New discoveries are being made all the time, much of which validates the age-old folk wisdom surrounding Chaga as a potent health tonic. Before any scientific analysis had taken place, Chaga had an indigenous reputation as a potent anti-aging/longevity medicine offering powerful immune support. Laboratory analysis have illustrated that wild Chaga possesses an abundance of beta glucans and other polysaccharides that have shown to nourish and support the immune system and significantly enhance the activity of all immunological cells. These polysaccharides balance the immune system rather than simply stimulate or suppress it because they plug directly into immune cell receptors and initiate an adaptogenic cycle throughout all levels of the immune system. These long chain polysacchraide sugars also impart a powerful anti-inflammatory action, and they have a somewhat bitter taste that is easily detectable in Chaga’s unique flavour – which also offers a delicious vanilla overtone!

Chaga is also known as being one of the richest sources of antioxidants found in nature, far exceeding many of the better known antioxidant rich substances like blueberries, acai and resveratrol to name a few. Chaga is a rich source of the free radical scavenger Super Oxide Dismutase (SOD) and also contains incredibly high levels of melanin – a deeply pigmented antioxidant that comprises the dark surface of Chaga and is used abundantly throughout the human body. Melanin has been revealed as a geno-protective nutrient, meaning that it can protect the integrity of DNA and reduce genetic mutations, and is present in large amounts in the skin and eyes and even regulates the function of the pineal gland in the brain.


Chaga also contains a number of triterpene compounds – most notable betulin and betulinic acid – which are present in concentrated amounts in Birch bark. Chaga accumulates and further concentrates these substances from the tree, making them many times more powerful. Analysis of Chaga’s triterpenes have illustrated pronounced antiviral, anti-inflammatory, anti-mutagenic, anti parasitic/anti candida as well as anti cancer/anti tumour properties amongst others. These triterpenes actually increase the delivery of oxygen throughout the body making the whole process much more efficient, while at the same time providing immense antioxidant support in order to protect against the oxidative stress that damages the cells and tissues of the body. Chaga is always striving for balance on every level and working towards a state of homeodynamis – the body’s ability to maintain equilibrium under stress, and to be able to change and adapt in order to flourish and thrive.

Chaga’s impressive assortment of beneficial compounds can be divided into two basic categories – all of Chaga’s immune enhancing polysaccharides are soluble in hot water whereas all of the triterpene compounds are soluble in strong alcohol. This is why dual extracts are so important, because they contain the full spectrum of Chaga’s beneficial nutrients and active constituents. Nyishar Wild Siberian Dual Extract Tincture is made with 100% whole dried Chaga and is completely natural and unadulterated. 95% rectified ethanol is used for the alcohol extraction as it is by far the most effective menstruum for drawing out all of these constituents, whereas the hot water extraction is done using freshly harvested local spring water. The end product is concentrated at a 2:1 ratio, meaning that by weight, it has taken two parts liquid for one part dried Chaga.

Nyishar Wild Siberian Chaga Dual Extract is an incredibly concentrated and potent extract. The whole Chaga is reduced to a very fine flour before being infused in 95% rectified ethanol, in order to create maximum surface area and allow for a superior extraction. Once this stage is complete the alcohol infusion is run through a tincture press. It is then decocted in freshly harvested wild spring water, and finally run through the tincture press a second time. Both the alcohol and the water extract the full spectrum of Chaga’s beneficial nutrients and medicinal constituents, and when combined make a complete and powerful tonic medicine. The finished dual extract is then bottled in miron violet glass in order to perfectly preserve the integrity of the medicine, and spends a minimum of 7 days inside a grounded pyramid before being made commercially available.

  1. I just watched your video on making the tea. In it you stated that you can reuse the chaga a few times. If you cook some up say on a Monday and would not need to boil another batch for a few days how do you keep the -grounds – if you will from going bad, in between boilings? Is it safe and without ruining its medicinal and nutritional value, to freeze, say if you boil up a, (net), quart and will not be using all of it in three days? I have grown very interested in using chaga and am trying to educate myself as much as possible before purchasing. It would seem to really investigate how ones body handles it you need to use it for a good month to take a better evaluation. Thanks

    1. The ground Chaga can be stored in an airtight container in the fridge for a few days no problem. Remember it is very antibacterial, antimicrobial and antiviral etc. I have left it out at room temperature during the warmer months to see how long it took to go mouldy, and it took weeks! Obviously you don’t want to leave it for this long, but it is a robust and resilient substance. Leaving it for 2 to 3 days is absolutely fine.

  2. Still trying to work out if dual extraction powder is not as efficiently absorbed as dual action tincture. Can you clarify this better and is your product available in australia or even allowed to be imported into Australia

    1. Hi Gwen,

      The concentrated dual-extract powder is very good, but as it must be digested prior to absorption will take longer to reach the bloodstream and some of that potency will be lost en route. Good quality powdered extracts can still be excellent though.

      The tincture however can be taken sublingually and if held in the mouth for a couple of minutes will absorb directly into the bloodstream via the capillaries underneath the tongue and inside the walls of the cheeks. This enables it to bypass digestion almost completely and become active within the blood in a couple of minutes.

      Nyishar products are not yet sold in Australia, but shipping to Australia is no problem at all – there are many customers from Oz that order regularly 🙂

  3. I see that the extract is not currently available. I am interested in ordering the powder but would like to know if you can steep it one cup at a time (since you indicated 1 teaspoon servings)? And if so, how long do you steep the tea? A friend gave me some chago chunks, which I have steeped three times. Love the tea! Thank You!
