Herbal extracts are concentrated substances derived from plants, known as Phytotherapy, where specific compounds are isolated to provide a targeted therapeutic effect. The ratio, often referred to as the drug extract ratio (DER), indicates the amount of raw plant material relative to the final extract quantity. For instance, a 1:3, 1;5 ratio means that 3 or 5 parts of the plant were used to produce one part of the extract, resulting in a highly concentrated form. This ratio is crucial for determining the potency and dosage of the herbal extract, ensuring consistency and efficacy in herbal supplements.
