For a herb to truly be Di Dao, the seed, spore or root from which the crop is seeded MUST come from the microclimate in which the herb or mushie is being grown. Furthermore, it must not be a domesticated, commercial, hybridized seed, spore or root, it must be consistently brought in from a wild to ensure we are growing a herb that has the wild blueprint that has been stamped upon these famous, and revered for thousands of years for this reason. When an operation tries to grow too fast, scale, bend to the wills of investors or get certain certifications, then the quality and integrity is most often lost in this way in particular.
