Plant extracts refer to substances with biological activity or specific components obtained from plants (including the whole plant, roots, stems, leaves, flowers, fruits, seeds, etc.) through physical or chemical extraction and separation processes. They are concentrated forms of the essence of plants, preserving their inherent characteristics and efficacy.

The effects of plant extracts are diverse and depend on the source plant and its active constituents. Common active ingredients include alkaloids, flavonoids, polysaccharides, saponins, volatile oils, and polyphenols. These components endow plant extracts with various physiological functions such as antioxidant, anti-inflammatory, antimicrobial, immune-boosting, lipid-regulating, and skincare benefits.

Plant extracts have a wide range of applications, primarily in the following sectors:

• Pharmaceuticals and Health Products: Used as natural or dietary supplements for disease prevention and adjuvant therapy. Examples include Ginkgo Biloba extract for cardiovascular health and Echinacea extract for immune support.
• Cosmetics and Skincare Products: Used as natural functional additives for whitening, moisturizing, anti-aging, and soothing the skin. Examples include Aloe Vera extract, Green Tea extract, and Licorice Root extract.
• Food and Beverages: Used as natural colorants, flavors, preservatives, or nutritional fortifiers. Examples include Paprika extract for color, Peppermint oil for flavor, and Green Tea extract.
• Agriculture: Used in the production of biopesticides for pest and disease control.

Compared to synthetic chemicals, plant extracts are generally considered to have advantages such as natural sourcing, fewer side effects, milder actions, and better bioavailability. They align with the modern consumer trend towards "green, healthy, and natural" products.
