Aloe vera has received a lot of scientific and commercial attention because of its activities in different therapeutic and industrial fields as a drought-resistant succulent plant of great ethnopharmacological importance. Traditionally used to heal wounds and soothe burns, the plant has been shown to further possess anticancer, antifungal, anti-inflammatory, gastroprotective, and hypoglycemic activities, which makes it one of the great versatile gifts of nature to modern healthcare. This review is aimed at providing in-depth views regarding bioactive composition, processing techniques, and functional applications of Aloe vera, especially for its role as a natural alternative to synthetic preservatives and chemical treatments. In the study, an attempt has been made to synthesize a spectrum of recent pharmacological advancements, phytochemical investigations, and industrial reports inculcating the importance of polysaccharides, enzymes, vitamins, and minerals in supporting the bioactivity of Aloe vera. It has been revealed that advances in the field of analytical chemistry through chromatographic and spectroscopic techniques have contributed to the characterization of these bioactive molecules for better quality assurance, product standardization, and the development of new formulations. Besides, the industrial operations that process Aloe vera into juice, concentrate, and powder for extensive use in medicines, cosmetics, nutraceuticals, and functional foods have enhanced antioxidant defense and anti-inflammatory effectiveness. Thus, the review concludes that Aloe vera has great potential to naturally replace synthetic compounds in food preservation, skincare, and treatment purposes. The authors have made a significant contribution by juxtaposing their compositional knowledge with application-oriented perspectives, framing Aloe vera as an environmentally sustainable resource for bioactive compounds. Despite there being issues of variations in plant constituents, challenges around standardization, and the clinical translation of experimental findings, social and practical implications are far-reaching, ranging from producing safer consumer products to establishing greener industrial standards. In conclusion, Aloe vera can be regarded as a plant of historical medicinal relevance and, at the same time, an emerging modern bio-resource with ever-growing application potential in the health, food, and cosmetic industries.
