Harvesting Guidelines
To harvest aloe vera, cut the mature outer leaves (18-24 months old) close to the base using a sharp knife, ensuring you leave the younger inner leaves intact. Slice open the leaves and scoop out the gel, using it fresh or storing it in the refrigerator for up to two weeks. Always avoid over-harvesting, allowing the plant time to heal and grow new leaves after each harvest.
Aloe vera, a revered plant used in both ancient and modern herbalism, has been known for its impressive array of healing properties. Historically, this succulent has been a part of human culture for thousands of years. Evidence suggests that aloe vera was utilized in ancient Egypt, where it appeared in tomb paintings and was integral to funerary rituals. Aloe vera’s therapeutic use can be traced as far back as 1750 BCE through Sumerian clay tablets, while Egyptian texts such as the Papyrus Ebers and the Book of Remedies referenced its medicinal benefits. It is said that Egyptian queens like Cleopatra and Nefertiti used aloe vera to preserve their skin’s beauty, applying it topically as part of their skincare rituals (1).
In modern medicine, aloe vera’s gel is known for its potent soothing effects, particularly in treating burns, sunburns, wounds, frostbite, and dermatitis. It has been scientifically validated for its ability to aid skin healing, reduce inflammation, and offer analgesic effects. Aloe vera contains compounds such as salicylic acid, magnesium, and various polysaccharides that contribute to its ability to reduce pain and inflammation, making it a popular ingredient in first-aid products.
Internally, aloe vera has long been used as a natural laxative due to its anthraquinone compounds. However, its benefits extend far beyond digestive health. Aloe vera has been traditionally used to balance metabolic issues, support kidney function, and even as an adjunct in chemotherapy to help alleviate side effects. More recently, studies have suggested that aloe vera may have antiviral properties, including its ability to inhibit the spread of HIV by limiting viral entry into healthy cells (2).
A particularly noteworthy area of research is its efficacy in managing chronic skin conditions such as psoriasis. A double-blind, placebo-controlled study examined the effects of aloe vera extract in a hydrophilic cream on individuals with moderate psoriasis. Over a four-week period, 83% of those using aloe vera extract saw significant improvement, with complete clearing of psoriatic plaques in many participants. In contrast, the placebo group showed only minimal improvement (3, 4). These results affirm aloe vera’s potential as a safe and effective topical treatment for psoriasis.
The versatility of aloe vera makes it a staple in both internal and external applications. It’s used in creams, gels, and ointments for healing, as well as in digestive formulations for its soothing and laxative properties. When using aloe vera internally, caution is advised, particularly for prolonged use. It is a potent cathartic and can lead to discomfort such as cramping and diarrhea when taken in large quantities over extended periods, potentially causing an electrolyte imbalance (5).
