Aloe vera, a succulent plant recognized by its thick, fleshy leaves, has been valued for centuries for its beneficial gel. This natural substance, found within the leaves, possesses properties suitable for various applications. Understanding how to properly harvest and prepare aloe vera leaves allows effective utilization of this versatile plant.
Harvesting and Preparing the Leaf
Select a mature, healthy outer leaf, ideally from a plant at least two to three years old, as these contain more gel. Use a sharp knife to make a clean cut as close to the plant’s base as possible, minimizing damage.
After harvesting, position the cut leaf upright in a container for 10 to 15 minutes. This allows aloin, a yellow-tinted liquid and skin irritant with strong laxative properties, to drain. Once drained, thoroughly wash the leaf under running water to remove any residue and dirt.
Next, place the leaf flat on a clean cutting board and trim away the spiny edges. Using a knife or vegetable peeler, slice off the green outer skin from both flat sides to expose the clear gel. Scoop out the gel with a spoon, ensuring no green skin or yellow latex is included. For a smoother consistency, the extracted gel can be blended until frothy.
Topical Applications
The clear gel from aloe vera leaves is widely used for its soothing and moisturizing skin properties. It contains anti-inflammatory and antibacterial compounds, making it suitable for minor skin irritations. Applied topically, it helps calm redness and discomfort.
Aloe vera gel can be applied to small cuts and abrasions to support healing. Its antibacterial qualities help prevent infection, and its wound-healing properties contribute to faster recovery. For sunburns, applying a thick layer of chilled gel provides a cooling sensation and helps reduce redness and peeling by hydrating the skin.
Aloe vera is beneficial for dry skin, as its gel is nearly 99% water and absorbs quickly without leaving a greasy residue. It creates a hydrating barrier, helping to retain moisture and improve overall texture. Spread the gel over the affected area and reapply as needed to maintain hydration and comfort.
Internal Uses
Consuming the clear inner aloe vera gel is sometimes suggested for digestive health. It can be incorporated into smoothies or juices, potentially aiding issues like acid reflux and indigestion. Ensure all traces of yellow latex (aloin) are completely removed before internal consumption.
Aloin is a potent stimulant laxative; ingestion can lead to abdominal cramps, diarrhea, dehydration, and electrolyte imbalances. High concentrations have been associated with potential kidney problems.
While some research indicates aloe vera may assist in regulating blood sugar levels for individuals with prediabetes or type 2 diabetes, more studies are needed to confirm these benefits. Due to potential side effects and careful preparation, consult a healthcare professional before internal use, especially for existing health conditions.
Safe Handling and Storage
Before applying aloe vera gel topically, perform a patch test for sensitivities or allergic reactions. Apply a small amount to a discreet area, like the inside of your elbow, and wait 5 to 10 minutes, or up to 24 hours, to observe any redness, burning, stinging, or rash. Discontinue use if an adverse reaction occurs.
Whole aloe vera leaves can be stored in the refrigerator for two to three weeks. To maximize freshness, wrap the cut end in plastic or a damp paper towel and store the leaf upright with the cut side down to allow residual aloin to drain.
Extracted aloe vera gel should be kept in an airtight container in the refrigerator and remains fresh for five to seven days. For longer-term storage, the gel can be frozen in ice cube trays, lasting six months to a year. Always discard stored aloe vera if you notice discoloration, an unusual odor, or mold.
