Harvesting aloe

Aloe vera is a fabulous healer for 1st degree burns, scrapes and cuts. Many people grow aloe plants in their homes as houseplants. It’s no wonder that they do. With the right amount of sun and a minimum amount of attention, aloe thrives.

The real problem for housebound aloes is that they gets too big for their pots and fall over. Keeping aloes properly pruned is essential for good plant health. Using the aloe gel from within the leaves, is essential to good human health. Don’t wait for burns. Aloe can be used inside and out. Just be sure to try a small amount of gel on the inside of your arm first then check the site later to see if you have a reaction. It is rare but some people are allergic to aloe vera.

Aloe has phytonutrients (also called “actives”) that increase production of collagen which is a key protein that our bodies use for wound healing. As handy as these phytonutrients are, they do degrade quickly and are difficult to stabilize. Refrigeration slows the break up of these important chemicals but when it comes down to it, fresh is best.

Contrary to some claims on the internet, most of the healing properties of aloe gel are produced by the rind. At last count, close to 85% of the desired phytonutrients are right next to the rind of the leaf. This is why using a sharp knife to scrape the gel from the inner leaf results in a superior product.

Keep in mind that like other plants, aloe has tools to defend itself. It has lined with a surprisingly sharp spines on the edge of the leaf and it produces a yellowish-orange sap which, if taken internally, causes impressive diarrhea. This sap is produced near the stalk. When cutting the leaf from the stalk, be sure to leave about 1/2 inch of space from the stalk. If your leaf starts oozing yellow sap, just cut off more of the end.

  8. Scrape the gel carefully off the rind. If a bit of leaf rind comes away with it, it’s ok. It is easier to apply without leaf rind.

  10. Discard remaining stalk and rind.


Aloe vera can be preserved in the refrigerator but keep in mind that it does degrade. Some people add ascorbic acid to it as a preservative. We suggest adding any leftover gel not applied to wounds into smoothies or whisked into juice.
