At Organicure quality is not a general commitment but a set of acceptance criteria measured lot by lot. The six criteria below are assessed on every lot arriving at the plant, and the shipping decision follows that assessment.

Which criteria do we assess in a dried drug?

• Species purity: the lot consists of a single species, with no look-alike species present
• Stem and twig ratio: the share of woody material other than leaf
• Foreign matter: soil, stones, fragments of other plants and inorganic material
• Colour: closeness to the species' own natural colour, with no yellowing or blackening
• Particle size: uniformity after sieving and conformity to the fraction the buyer requires
• Moisture: controlled at a level that prevents mould through storage and transport

Why do we put species purity first?

In wild collection the greatest risk is not the wrong species but the admixture of a similar one. Horsetail mixed with marsh horsetail, or raspberry leaf with blackberry leaf, are typical examples. Because this distinction becomes harder to judge as particle size decreases in the dried drug, species control is carried out at harvest and at intake, and doubtful material is not admitted to the lot.

Why are colour and moisture assessed together?

Colour loss in a dried drug has two principal causes: drying in direct sunlight, and a long interval between harvest and drying. Moisture carries the opposite risk: insufficient drying leads to mould, while excessive drying causes fragmentation and raises the dust fraction. The two criteria are therefore never considered in isolation.

What happens to a lot that fails the criteria?

A lot found non-conforming is not shipped. Depending on the nature of the defect, the material returns to cleaning or re-sieving; where species admixture or mould is involved, the lot is separated in full. If this causes a delay to a buyer's order, it is communicated before shipment.

How does a buyer specification work?

Most industrial buyers send their own specification, which may add numerical limits to the criteria above or define a minimum value based on a constituent. Sharing the specification before the order allows the correct species and the correct fraction to be planned from the outset.
