Chaga, Latin botanical name Inonotus obliquus, also known as birch conk, refers to the dried mature sclerotia of the fungus growing on birch trees. Our dried whole chaga sclerotia go through a complete processing workflow including mature sclerotia harvesting, rinsing, trimming, low-temperature dehydration, impurity removal and manual sorting. Only physical processing steps are applied to retain the natural block shape, characteristic mild earthy, faintly vanilla herbal aroma and inherent natural compounds found within raw chaga. No chemical modification or extra additives are introduced during processing, preserving the natural traits of this dried fungal raw material.

Many chaga products available on the market use simple sorting workflows, which may contain broken fragments, bark debris and underdeveloped sclerotia in finished batches. Our chaga is harvested sustainably from cold-climate birch forest areas. We carefully screen out immature sclerotia, broken pieces, discoloured se

We supply food-grade whole dried chaga sclerotia (Inonotus obliquus) with multiple grading options. Different chunk size grades can be selected to match requirements for botanical tea mixing, food formulation and plant ingredient compounding. Each batch is inspected and tested by third-party independent laboratories to meet international food safety and clean-label standards.

Inonotus obliquus is a wood-inhabiting fungus whose sclerotia naturally accumulate a range of fungal substances during slow growth on birch trunks. Our whole dried chaga sclerotia are harvested at full maturity, then gently dried and sorted to keep the natural fungal structure and original earthy, slightly bitter flavour with light vanilla undertones. With stable physical properties and flexible application options, this botanical raw material fits the global market trend for natural, plant-based and clean-label food ingredients.

Thanks to its natural whole-block form, distinctive mild earthy aroma and stable batch quality, chaga (Inonotus obliquus) is widely used in global botanical tea, beverage and food ingredient manufacturing industries:

We operate standardized chaga cleaning and drying lines. Stable raw material sourcing and complete batch inspection systems help maintain consistent block appearance, low impurity levels and fresh natural earthy flavour for bulk export orders.
