History and Scientific Overview of Aloe Vera (Aloe vera)

History of Aloe Vera and Traditional Uses

Aloe vera has been used since ancient civilizations. Historical records indicate that Egyptians utilized this plant more than six thousand years ago. Both Cleopatra and Nefertiti included Aloe vera in their daily beauty routines. Its anti-inflammatory and pain-relieving properties were documented in the Ebers Papyrus in 1550 BCE.

In Mesopotamia, Aloe vera was used for intestinal purification. Additionally, historical evidence shows that Alexander the Great (356–323 BCE) used Aloe vera to treat the wounds of his soldiers.

Around 50 BCE, the Roman physician Dioscorides traveled to the Middle East in search of medicinal therapies. During his journey, he recommended Aloe vera juice for treating multiple physical conditions, including:

• Sunburns
• Gingivitis
• Wounds
• Arthritis
• Hair loss
• And various other ailments

Aloe vera has also played a notable role in Chinese medicine since the time of Marco Polo’s expeditions, where it was an essential component of medical treatments and part of daily life. In Japan, Aloe vera was known as the “royal plant,” and its juice was used as an elixir.

Christopher Columbus used Aloe vera for wound healing, while the Maya people regarded Aloe vera juice as a “fountain of youth.” In Indian traditional medicine, Aloe vera was used for various therapeutic purposes, such as:

• Rejuvenation
• Menopausal discomfort
• Stabilizing the cardiovascular system

In Ayurvedic tradition, Aloe vera is considered a balancing agent for Vata, Pitta, and Kapha. Historically, diluted Aloe vera juice was applied to the skin to protect against insects during travel in swampy regions, and it was also used as an insect repellent for wood and other materials prone to insect damage.

Introduction to Aloe Vera Plant

Aloe vera is a perennial, evergreen succulent belonging to the family Aloe barbadensis Miller. It originated in the southwestern region of the Arabian Peninsula but now grows naturally across tropical, subtropical, and arid climates worldwide. It is cultivated for agricultural, medicinal, and ornamental purposes and can also be grown indoors.

Aloe vera is widely used in:

• Facial cleansers
• Cosmetic products
• Medicinal ointments
• Gel preparations for minor burns and sunburns

Aloe vera is characterized by a rich, complex chemical composition, containing vitamins, minerals, enzymes, sugars, plant hormones, amino acids, and multiple biologically active compounds essential for its therapeutic effects.

Below is the complete composition of Aloe vera without removing any information from the original text:

.Composition of Aloe Vera

1) Vitamins in Aloe Vera

Aloe vera contains vitamins A, C, and E, in addition to vitamin B12, folic acid, and choline.
These vitamins act as antioxidants that neutralize harmful free radicals.

2) Enzymes in Aloe Vera

Aloe vera contains eight key enzymes:

• Alkaline phosphatase
• Amylase
• Bradykinase
• Carboxypeptidase
• Catalase
• Cellulase
• Lipase
• Peroxidase

Bradykinase helps reduce excessive inflammation when applied topically, while the remaining enzymes support the breakdown of sugars and fats.

3) Minerals in Aloe Vera

Aloe vera provides essential minerals, including:
Calcium, chromium, copper, selenium, magnesium, manganese, potassium, sodium, and zinc.
These minerals are vital for enzyme activity and various metabolic processes.

4) Polysaccharides and Active Sugars

Aloe vera contains monosaccharides such as glucose and fructose, as well as polysaccharides such as glucomannan/polymannose derived from the plant’s mucilage layer.

The polysaccharide Acemannan, a type of glucomannan, is one of its major active components.

Recent research has identified:

• Alprogen: a glycoprotein with anti-allergic properties
• C-glucosyl chromone: a newly isolated anti-inflammatory compound in Aloe vera gel

5) Anthraquinones 

Aloe vera contains 12 anthraquinones, which are phenolic compounds traditionally known for their laxative properties.

Two key active compounds:

• Aloin
• Emodin

These exhibit analgesic, antibacterial, and antiviral activities.

6) Fatty Acids

Aloe vera contains plant sterols such as:

• Cholesterol
• Campesterol
• β-Sitosterol
• Lupeol

All possess anti-inflammatory properties, and lupeol also exhibits antiseptic and analgesic effects.

7) Plant Hormones 

Aloe vera contains auxins and gibberellins, both of which support wound healing and exhibit anti-inflammatory effects.

8) Amino Acids

Aloe vera provides:

• 20 of the 22 amino acids required by the human body
• 7 of the 8 essential amino acids
