What it is: A succulent plant that has long, spiked leaves, which are thick-skinned and contain a clear gel-like substance. There are more than 200 varieties of these desert lilies. Aloe vera, which means “true aloe” in Latin, is generally the most widely used and most effective species of aloe.

Where it comes from: While thought to have originated in northern Africa, aloe vera plants are readily available and some people even keep a potted plant in the kitchen. The plant can be grown inside and outside. A leaf spike may be cut open and the gel applied directly to a cut or burn.

Properties: Aloe vera contains numerous vitamins and minerals, enzymes, amino acids, natural sugars, and agents that are anti-inflammatory and anti-microbial. The combination and balance of the plant’s ingredients are what purportedly gives it its soothing, healing properties.

What it’s good for: Aloes have been used worldwide for more than 3,500 years. Today aloe vera continues to be widely used. Studies have shown that aloe vera speeds the healing process, particularly in burns, including those from radiation. It is also used by dermatologists to speed healing after facial dermabrasion, which removes scars from the skin’s top layers.

Where you’ll find it: Aloe vera is used in body and hand lotions, as well as in capsule, gel, cream, spray, and liquid forms. It is also a key ingredient in post-sun care products.

Other uses: Ingesting aloe vera juice is thought to help treat digestive disorders, ulcers, and heartburn. Aloe vera is thought to be beneficial in the reducing of scalp care, stings, sunburns, sore muscles, scrapes, scalds, psoriasis, acne, burns, arthritis, sprains, bruises, cold sores, and abrasions.
