Introduction

Aloe vera, scientifically known as Aloe barbadensis miller, is a species of succulent plant that belongs to the Aloe genus. Native to the Arabian Peninsula, it thrives in dry, tropical climates and has been cultivated worldwide for its medicinal and agricultural uses. The gel extracted from its fleshy leaves is renowned for its therapeutic properties, making it a staple ingredient in cosmetics, skincare products, herbal remedies, and even dietary supplements.

Historical Roots

The use of aloe vera dates back thousands of years, with historical evidence of its medicinal and cosmetic applications found in ancient civilizations:

1. Ancient Egypt:
   • Egyptian queens Cleopatra and Nefertiti reportedly used aloe vera as part of their beauty regimen. It was referred to as the “plant of immortality” and depicted in hieroglyphs on temple walls.
2. Traditional Chinese Medicine (TCM):
   • Aloe vera was introduced to China from Arabia in the 17th century and incorporated into TCM for its cooling, hydrating, and detoxifying properties.
3. Ayurveda:
   • In India, aloe vera is known as “kumari” and has been used in Ayurvedic medicine for over 6,000 years to treat skin conditions, digestive disorders, and as a general tonic.
4. Greek and Roman Civilizations:
   • Greek physician Dioscorides and Roman naturalist Pliny the Elder documented the medicinal uses of aloe vera in their works, highlighting its effectiveness in wound healing and gastrointestinal ailments.

Botanical Characteristics and Composition

Aloe vera is characterized by its rosette of thick, fleshy leaves that contain a clear gel and a yellowish latex. The gel, found in the inner layers of the leaves, is rich in bioactive compounds, including:

• Polysaccharides: Mainly acemannan, which supports immune function and skin health.
• Enzymes: Such as amylase and lipase, which aid in digestion and metabolism.
• Vitamins: Including vitamin A (beta-carotene), vitamin C, and vitamin E, with antioxidant properties.
• Minerals: Such as calcium, magnesium, zinc, and selenium, essential for various physiological functions.
• Amino Acids: Building blocks of proteins that support tissue repair and growth.

The latex, or sap, found just beneath the outer leaf skin, contains anthraquinones like aloin, known for its laxative effects. Commercially, the latex is sometimes used for its purgative properties, although its consumption is regulated due to potential adverse effects.
