Using hydro produced roots is obviously easier to use as the cleaning phase isn’t needed.
Hang the roots to dry, then cut them up into smaller pieces and chop them in a blender. Keep the ground roots in a glass jar till needed. Compost the fiber or as our ancestors did, make thread or rope.
Terpenes
Cannabis roots contain terpenes that are found nowhere else in the plant; Friedelin and Epifriedelonol. Historically ground cannabis roots have been used in poultices, lotions, and juiced for use in child birth.
These two terpenes are: pain killers, anti nausea, anti cancer, anti tumour, anti inflammatory and anti ulcerative. Used as a poultice it can relieve the pain from Gout. As a topical for skin cancers.
