11.1 Medicinal plants/herbal drugs should be harvested when they are at the best possible quality for the proposed use.
11.2 Damaged plants or parts plants need to be excluded.
11.3 Medicinal plants/herbal drugs should be harvested under the best possible conditions avoiding wet soil, dew, rain or exceptionally high air humidity. If harvesting occurs in wet conditions possible adverse effects on the medicinal plant/herbal drug due to increased moisture levels should be counteracted.
11.4 Cutting devices or harvesters must be adjusted such that contamination from soil particles is reduced to a minimum.
11.5 The harvested medicinal plant/herbal drug should not come into direct contact with the soil. It must be promptly collected and transported in dry, clean conditions.
11.6 During harvesting, care should be taken to ensure that no toxic weeds mix with harvested medicinal plants/herbal drugs.
