These results show:
• that occasionally herbal drugs are adulterated with foreign or even toxic plants. This applies especially to plants from collection in wild habitats, where confusion with similar plants as well as poorly qualified personnel presents a risk for the quality of the herbal drug,
• that especially the identity and purity of herbal TC(M) drugs is problematic and
• that regular tests for confusions/admixtures/adulterations
on one side,
• but also on heavy metals, pesticides, mycotoxins and microbiological counts are required
to get appropriate quality information.

� Most MAP species are now – and will continue to be – wild collected!
� Cultivation cannot be the principal solution to over-harvesting!
Ca. 900 MAP species are commercially cultivated.

Estimation of wild collection• (70)-90% in terms of species numbers• 50-(70%) in terms of quantity
Production of MAPs
About 15,000 medicinal plant species may be threate ned to some degree world-wide (IUCN).Make wild collection sustainable now !

Challenges for a Standard on Sustainable Wild Collection of MAP
• Unique circumstances of ecology, habitat, and pressures on resource for each species
• Harvesting techniques: Questions about “how to” collect wild MAP sustainably
• Uncertainty about annual sustained yield

54
55
Challenges for a Standard on Sustainable Wild Collection of MAP
• Large number of products, uses, and markets
• Proliferation of labels and claims regarding sustainability without means for validation
• Long and complex supply chains – difficult to trace product back to its source

ISSC-MAP – Purpose
To ensure the continued use and long-term survival
of medicinal and aromatic plant (MAP) species and populations in their habitats, while respecting the traditions, cultures and livelihoods of all stakeholders.
59
ISSC-MAP – Objectives
• To provide a framework of principles and criteria that can be applied to the management of MAP species and their ecosystems
• To provide guidance for management planning
• To serve as a basis for monitoring and reporting, and
• To recommend requirements for certification of sustainable wild collection of MAPs.

Who benefits from a widely accepted, credible standard?• Industry ���� sustainable resource use and corporate
social and environmental responsibility
• Resource managers ���� guidelines for MAP protection, harvest, and monitoring
• Collectors ���� insurance against resource and market failures
• Consumers ���� reliability of claims about ecological sustainability and fair trade
• Species and habitats ���� maintain biodiversity

Cutting and drying of plants, algae, fungi, lichens and exudates ‘on farm’ only!
Expression from plants and Distillation *
Comminution, processing of exudates, extraction from plants, fractionation, purification, concentration or fermentation of herbal substances substances
Further processing into a dosage form including packaging as a medicinal product

Premises , Equipment etc.
• Storage areas: separate and protected (against insects, animals,… well
aerated, clean, protection against high humidity, temperatur, light
• Production area: protected against dust (especially at manufacturing;
avoid cross-contamination!)
• Equipment: compatible with the extraction solvent
• Documentation: Specifications for starting materials in compliance with GACP,
incl. nomenclature, residues...
• Processing Instructions – Quality Control – Sampling: in compliance
