Resource sustainability is crucial and great care is taken to ensure that any harvesting of parts of the plant do not negatively impact on the plants survival. For all the plants that are used in the production of essential oils or other products extensive research on various aspects related but not limited to resource distribution, method of harvesting, potential offtake and traditional knowledge is carried out prior to any commercialisation.

In order to ensure that harvesting is carried out with minimal negative impact and to guarantee that high quality standards are met, harvesters are fully trained with respect to harvesting methods, basic processing, handling and storage of any of the plants used in the production of essential oils at the Opuwo Processing Facility.
