1. Definition of Plant Extracts

Plant extracts are concentrated forms of active compounds derived from various parts of plants, such as leaves, roots, seeds, and fruits. These extracts are typically obtained through a process of extraction, which involves the use of solvents, heat, or pressure to separate and concentrate the beneficial components from the plant material. The resulting extracts are then used in dietary supplements to provide a concentrated source of the plant's natural nutrients, bioactive compounds, and therapeutic properties.

Plant extracts are valued for their diverse range of health benefits, which can include antioxidant, anti-inflammatory, immune-boosting, and disease-preventing properties. They are often used to support overall health and well-being, as well as to address specific health concerns or conditions.

The use of plant extracts in supplements is based on the concept of herbal medicine, which has been practiced for thousands of years in various cultures around the world. Today, with advancements in science and technology, the health-promoting properties of plant extracts are being studied and validated through modern research, further enhancing their credibility and acceptance as a natural approach to health and wellness.
