How to make a proper herbal tea?

The most common dosage form of herbal medicines is a herbal tea mixture (species). Whether it is packed in tea bags or loose, the preparation of herbal tea has some rules. From the chemical point of view, it is an extraction. Extraction conditions determine what is extracted, how quickly and how much. There are three methods of herbal tea preparation:

Maceration – the plant material is soaked in cold water and macerated for several hours (overnight), then strained.

Infusion (infusum) – boiling water is poured over the plant material and kept in a covered vessel for 15 minutes, then strained.

Decoction (decoctum) – the plant material is soaked with cold water and then boiled for 30 minutes, then strained.
