EXTERNAL USE OF GOLDENROD
- Vulnerary: The main action of goldenrod in external use is due to its vulnerary properties for wound healing. This effect is due to the tannin content of this plant. Tannins form complexes with the macromolecules of skin, excising the tissues, sealing them and producing a slighly shallow vasoconstriction. They also exert an antiseptic and antihemorrhagic action.
Because of tannis, this plant is used to clean wounds and improve healing. (Compresses. 50-100g decoction of dried plant per liter of water, cool, strain, and apply to the skin, superficial cuts or wounds, burns, skin diseases, with a clean chiffon. Cooling serves the compress not to burn the skin, but also this time of rest favors the tannins to be released into the water). The same remedy is used for thrush or mouth sores (by means of gargling).
