These chunks are sourced, from wild-harvested Chaga mushrooms hand-picked, raw from the wilds of the Cairngorms National Park in the Scottish Highlands.

Chaga mushrooms (Inonotus obliquus) are found in the northern forests around the globe. They particularly like to grow on birch trees, and take many years to reach a good size.

There is a tradition of drinking chaga mushroom tea going back many hundreds of years - maybe even thousands of years.

The resulting tea is very dark and contains a range of antioxidants, including a nutrient called melanin.

Chaga tea has a faint hint of vanilla flavour, and so adding a little more vanilla powder or essence to your tea makes a very pleasing drink.
