Echinacea is a lovely looking plant, with colorful flowers. Still, for most of us, it is easier to have it in a dried form, than to grow it in the garden. It can be used externally, in the case of wounds and cuts, as it has a powerful antiseptic action. Or internally, for cases of flu, colds, even blood poisoning, under the shape of tea. Dried Echinacea can be easily found in shops that sell natural products and alternative treatments.
