About Tundra Crowberry (Shiksha)

Tundra Crowberry (Shiksha) (Empetrum nigrum) is a herb used in the Russian & Siberian Folk Medicine tradition to help with Headache, Fatigue, Kidney Support, and Eye Health. The aerial parts and leaves are the parts traditionally used, taken internally.

Botanical background

Empetrum nigrum, crowberry, black crowberry, or, in western Alaska, blackberry, is a flowering plant species in the heather family Ericaceae with a near circumboreal distribution in the northern hemisphere. It is also native in the Falkland Islands. It is usually dioecious, but there is a bisexual tetraploid subspecies, Empetrum nigrum ssp. hermaphroditum, that occurs in more northerly locations and at higher altitude.

Quality tips

When buying Tundra Crowberry (Shiksha), look for: certified organic labelling, clearly stated country of origin, third-party lab testing for heavy metals and pesticides, and a batch expiry date. Standardised extracts offer consistent dosing; bulk dried herbs are more economical for regular use. Avoid very cheap, unlabelled products — quality varies enormously.
