Forms, Preparation and Usage

Aloe vera has been widely used for its therapeutic properties in various forms, including fresh gel, dried tincture, powder, essential oil, and capsules.

It can be prepared through different methods such as making tea from the leaves, creating a decoction by boiling the plant, or using an infusion for topical application. For internal use, the recommended dosage for adults is typically 100-200 milligrams of powder or 1-2 capsules per day, while children should only use it under medical supervision. Topical application is generally more common, with the gel applied directly to the skin for conditions like burns or skin irritation.

Due to its potency, it is advisable to use aloe vera sparingly and for short durations, unless directed by a healthcare professional.

Safety, Side Effects and Contraindications

Aloe vera can be a beneficial medicinal plant for various skin and digestive conditions when used appropriately, but it also carries potential risks.

While generally safe for short-term use in small amounts, it may cause side effects such as gastrointestinal discomfort, diarrhea, or nausea, particularly when consumed in large quantities. Aloe vera may interact with certain medications, including laxatives, diuretics, and drugs affecting the kidneys or heart, so it is important to consult a healthcare provider before combining it with other treatments. Special populations, such as pregnant or breastfeeding women, should avoid internal use due to potential risks to the fetus or infant, and individuals with chronic illnesses should use it cautiously under medical supervision.

To ensure safety, always use aloe vera in recommended doses, opt for products labeled for internal or topical use, and discontinue use if adverse reactions occur.

Growing, Harvesting and Storage

Aloe vera grows best in well-draining soil, full sun to partial shade, and a warm, arid climate, making it ideal for tropical and subtropical regions.

It requires moderate watering, allowing the soil to dry out between waterings to prevent root rot, and thrives in sandy or loamy soils with a pH between 6.0 and 7.5. Regular pruning of dead or damaged leaves and occasional fertilization with a balanced, water-soluble fertilizer during the growing season help maintain its health and productivity. The best time to harvest aloe vera is when the leaves are fully mature, typically after 12 to 18 months, by carefully cutting the outer leaves at the base with a sharp knife to avoid damaging the plant.

To preserve its potency, harvested leaves should be dried in a cool, shaded area or stored in airtight containers in the refrigerator, ensuring the gel remains fresh and retains its medicinal properties.
