According to Herbal Therapists, Calendula can be decoctioned if boiled for 10-15 minutes in water (estimate that you will need 5g for each cup of beverage). You can consume up to 3 cups of Calendula a day (morning, noon, evening before lunch). If you want to prepare a compress, simply place a quantity of herb in a saucepan, cover with water and simmer for 10-15 minutes. Drain the herb and dip a clean cloth (towel, gauze, etc.) into the decoction. Place the cloth on the skin (as long as it is warm). Alternatively you can make a poultice by wrapping the herb boiled in a gauze and fastening it to the body.
