Use only unblemished roots or bark. Gather the plant when it is in full bloom, the seed when it is ripening, the bark whenit is rising. Dig roots in the spring or late autumn and collect barks in spring or autumn. If you live the country you will want to investigate the many weeds, wild flowers, roots and barks that you can discover either in your own garden, or by the roadside, or in wastelands or meadows. Before you use these herbs on your body or hair, check whether there has been any spraying in that area.
Many people collect their herbs when they are already dried on the plant.
This lessens the strength and value of the herb. Scentless herbs can be dried in the sun, but herbs with an aroma should be dried entirely in the shade, after which they can be put in the sun for a short time to prevent fungus formulation. Sometimes, in a cold climate it is necessary to use heat, but use only slow heat. Roots should be dried in the shade. Slice or put in bunches and store in a cool, dry, airy place.
