This Sustainability Guide uses a ‘traffic-light’ designation of Green-Amber-Red. It is intended as a guide, not an absolute designation.

It has been collated by our Herbal Reality team and research with TRAFFICCITESNational Red or Endangered ListsFairWildUnited Plant SaversSustainable Herbs Program.

With over 70,000 plants used in herbal traditions and only 3,000 cultivated commercially, it is important that you know where your herbs come from, whether they are grown or wild-harvested, and how they are grown or wild-harvested.

As the increasing interest in natural health solutions can put pressure on wild sources, it is essential to buy herbs with a known history.

Impact of harvesting different plant parts:

  • Barks: Removal of barks can kill trees. Taking many years to regenerate, they should be either coppiced or removed in a rotation.
  • Resins: Tapping the resin of plants can drain nutritive reserves and weaken defences.
  • Roots: Digging roots can remove the whole plant, reducing the potential for future growth and damaging population densities.
  • Flowers: Prevents the formation of seeds and furthering of genetic diversity.
  • Seeds: Harvesting can prevent the spread of genetic diversity and reduce local populations.
  • Fruits: Harvesting reduces the potential for spreading the seed.

Before you buy, ask yourself:

  • Where is this species/herb/product grown?
  • Is there any environmental certification – e.g. Organic?
  • Is there any social certification – e.g. Fairtrade?
  • Is the herb from the wild? If so, is it certified – e.g. by FairWild?
  • Is there a mention of quality standards?
  • If not, why not?!
