Cultivation and harvesting are performed according to the company's quality manual and GAP guidelines (Good Agricultural Practice). There is a separate harvesting procedure for each medicinal plant which contains specific requirements:

• Description of the harvesting procedure
• Post-harvesting operations, e.g. documentation, determination of yield etc.

Standard operating procedures exist for all harvests. They are reviewed annually and updated if necessary. The employees working in the WALA herb garden are regularly trained in implementation of the procedures.
