Walnut Root Bark

The bark of walnut roots for medical purposes is collected in the fall, in September-October. Dry it in sunny weather under a canopy, and in cloudy weather - in a well-ventilated, dry room. (In any case, the bark must be kept in the house at night.) 

The finished dried bark is ground into a powder and transferred to paper bags. The shelf life of the bark is 3-5 years.
