An infusion or infusion (Latin infusum "the infusion", Latin infusio "the pouring in", cf. infusion) is a watery extract that is made by pouring hot or boiling water over solid drugs (e.g. herbs, fruits, parts of plants). Water is obtained.
You pour boiling water over the drug, then let the tea steep for 10 to 20 minutes - depending on the type - and then strain it through a sieve, squeezing out the drug a little. The amount used depends on the type of plant, the intended use of the infusion and whether fresh or dried plants are used. For medicinal use, depending on the type of plant, around 2 to 4 g of dried herb are usually used in 150 ml of water. If fresh plants are used, the amount required is approximately 4 to 5 tablespoons of the coarsely chopped herb. Dry fruits, such as fennel, anise, caraway, should be crushed in a mortar before pouring.
Infusing herbal ingredients can be done in a heatproof pot or jug. The hot water causes medicinal and aromatic substances to be dissolved from the ingredients. These can then either be taken as an infusion drink (e.g. herbal tea or fruit tea) or used for inhalation as a remedy for respiratory diseases (e.g. runny nose and cold).
This method of making tea is the most common method and can also be used for drugs that contain volatile components (essential oils). However, you should cover the container well while “pulling”. This process is suitable for most leaf, herb and flower drugs as well as for the fruits of the umbelliferous plants.
