Its flowers are used to make extracts that are beneficial for digestion and relaxation.

3. Extraction Methods

The extraction of plant extracts involves various techniques, each with its own advantages and limitations.

3.1 Solvent Extraction

Solvent extraction is one of the most commonly used methods. It involves using a solvent, such as ethanol or hexane, to dissolve the desired components from the plant material. For example, when extracting flavonoids from a plant, ethanol may be used as the solvent. The plant material is soaked in the solvent for a period of time, allowing the flavonoids to dissolve into the solvent. The mixture is then filtered to separate the plant residue from the solvent - containing the extract. However, one of the challenges with solvent extraction is the potential for solvent residues to remain in the final extract, which may pose safety concerns.

3.2 Steam Distillation

Steam distillation is mainly used for extracting essential oils. In this process, steam is passed through the plant material. The heat causes the volatile compounds in the plant, such as essential oils, to vaporize. The vapor is then condensed back into a liquid, which is collected as the essential oil extract. For instance, when extracting peppermint essential oil, steam distillation is often employed. The advantage of this method is that it is a relatively gentle process that can preserve the integrity of the volatile compounds. However, it is mainly suitable for extracting volatile substances and may not be effective for non - volatile bioactive components.

3.3 Supercritical Fluid Extraction

Supercritical fluid extraction uses a supercritical fluid, typically carbon dioxide, as the extraction medium. Carbon dioxide in its supercritical state has properties that make it an excellent solvent for many plant components. It can penetrate the plant material and dissolve the target compounds effectively. This method has the advantage of being relatively clean, as carbon dioxide is a non - toxic and easily removable gas. After the extraction, the carbon dioxide can be easily removed from the extract, leaving behind a pure extract. However, the equipment required for supercritical fluid extraction is expensive, which limits its widespread use.

4. Diverse Applications of Plant Extracts
