Aloe vera, sometimes described as a “wonderful plant”, is a shrub with a short stem. Aloe is a genus that contains over 500 species of flowering succulents. Many aloes are found naturally in North Africa.

The aloe vera leaves are succulent, erect, and form a dense rosette. Many uses are made of the gel obtained from the leaves of the plant.

Aloe vera has been the subject of numerous scientific studies in recent years, relating to various claimed therapeutic properties. In this article, we’ll take a look at some of these claims and investigate the research behind them.

What is aloe vera?

Aloe vera gel has many medicinal properties and is often used in creams and lotions.

According to Kew Gardens, England’s Royal Botanical Center of Excellence, aloe vera has been used for centuries and is now more popular than ever.

It is cultivated all over the world, mainly as an “aloe gel” culture, which comes from the leaf.

Aloe vera is now widely used in:

  • Food: It is FDA-approved as a flavoring.
  • Cosmetic products.
  • Food supplements.
  • Herbal remedies.

The oldest record of human use of Aloe vera comes from the Ebers papyrus (an Egyptian medical record) from the 16th century BC. C. According to a study published in the Indian Journal of Dermatology, in ancient Egypt, they called Aloe vera “that plant of immortality”. The authors added that the plant has been used for therapeutic purposes for many centuries. A reliable source in China, Japan, India, Greece, Egypt, Mexico, and Japan.


The medicinal claims made about Aloe vera, like many herbs and plants, are endless. Some are backed by rigorous scientific studies, while others are not. This article mainly focuses on those who are supported by research.

1. Teeth and gums

A study published in General Dentistry reported that aloe vera in dental gels is as effective as toothpaste in fighting cavities.

Researchers compared the germ-fighting ability of an aloe vera tooth gel to two popular kinds of toothpaste. They found the gel to be just as effective and in some cases even better than commercial toothpaste at controlling oral bacteria that cause cavities.

The authors explain that aloe latex contains anthraquinones, compounds that actively heal and reduce pain through natural anti-inflammatory effects.

Scientists warned that not all of the gels they tested contained the correct form of Aloe vera; they must contain the stabilized gel that exists in the center of the plant to be effective.

2. Constipation

The German herbal regulatory agency Commission E has approved the use of aloe vera for the treatment of constipation. Doses of 50 to 200 milligrams of aloe latex are usually taken as a liquid or capsule once a day for up to 10 days.

The United States Food and Drug Administration (FDA) ruled in 2002 that there was insufficient data on the safety and effectiveness of aloe products; Therefore, in the United States, they cannot be sold to treat constipation.

3. Diabetes-induced foot ulcers

A study conducted at Sinhgad College of Pharmacy, India, and published in the International Wound Journal Trusted Source examined Aloe’s ability to treat ulcers.

They reported that a “gel formed with carbopol 974p (1%) and aloe vera promotes wound healing and closure in diabetic rats compared to the commercial product and provides a promising product for use in Diabetes-Induced Foot Ulcers “.

4. Possible antioxidant and antimicrobial properties

Aloe vera can be used on skin conditions or superficial cuts for its antimicrobial and antioxidant properties.

Researchers at the University of Las Palmas de Gran Canaria, Spain, published a study in the journal Molecules.

The team investigated whether the methanol extract from the skin of Aloe vera leaves and flowers could have beneficial effects on human health. Scientists focused on the extract’s potential antioxidant and anti-mycoplasma activities.

Mycoplasma is a type of bacteria that does not have a cell wall; they are not affected by many common antibiotics. Anti-mycoplasma substances destroy these bacteria.

They reported that Aloe vera leaf and flower extracts had antioxidant properties, especially the skin extract from the leaves. The leaf skin extract also exhibited anti-mycoplasma properties.

The authors conclude that “A. Extracts of Vera from the skin of leaves and flowers can be considered good natural sources of antioxidants.”

5. Protection against ultraviolet (UV) rays

Scientists at the Global Campus of Kyung Hee University in South Korea wanted to determine whether baby aloe bud extract and adult aloe bud extract could have a protective effect on photoaging of the skin. UVB-induced skin; in other words, if they could protect the skin from the effects of aging in the sun.

Baby Aloe Bud Extract (BAE) comes from 1-month-old shoots, while Adult Aloe Bud Extract (AE) comes from 4-month-old shoots.

In an article published in Phytotherapy Research, the authors concluded Trusted Source: “Our results suggest that BAE can potentially protect the skin from UVB-induced damage more than EA.”

6.Protection against skin lesions after radiotherapy.

A study at the University of Naples, Italy tested five different topical creams to see how effective they might be in protecting the skin of breast cancer patients receiving radiation therapy. One of these creams contained aloe vera.

They divided 100 patients into five groups of 20; each received a different topical treatment. The creams were applied twice a day, starting 15 days before the radiotherapy treatment and continuing for 1 month after.

During the 6 weeks, participants underwent weekly skin assessments.

In the journal Radiation Oncology, scientists reported that the preventive use of topical moisturizers reduced the incidence of skin side effects in women treated with radiation therapy for breast cancer, none gave better results.

“All of the moisturizers used in this study were also valid in the treatment of skin lesions induced by radiation therapy.”

7.Depression, learning, and memory: an animal experiment

A study published in Nutritional Neuroscience found that aloe vera reduced depression and improved memory in mice.

After performing experiments on lab mice, they concluded: “Aloe vera improves learning and memory, and also relieves depression in mice.

More studies are needed to establish whether humans might also experience the same benefits.

8. Wounds from Second-degree burns

A team of plastic surgeons compared aloe vera gel to 1% silver sulfadiazine cream for the treatment of second-degree burns.

They reported in the Journal of the Pakistan Medical Association that burns in patients treated with Aloe vera healed much faster than those treated with 1 percent silver sulfadiazine (SSD).

The researchers added that those in the Aloe vera group experienced significantly greater and earlier pain relief than those in the SSD group.

The authors wrote: “Heat burn patients clad in aloe vera gel have shown advantages over SSD dresses in terms of early wound epithelialization, early pain relief, and cost-effectiveness.”

9.Irritable bowel syndrome (IBS)

A randomized, double-blind human trial conducted at St. George’s Hospital School of Medicine, London, UK, studied aloe and IBS. Their results have been published in the International Journal of Clinical Practice. Participants with IBS were given either aloe vera or a placebo. After 3 months, there were no significant differences in symptoms of diarrhea.

However, the researchers wrote a reliable source:

“There was no evidence that AV [Aloe vera] benefits patients with IBS. However, we could not rule out the possibility of improvement occurring in patients with diarrhea or alternative IBS while taking VA. More research is warranted in patients with predominantly diarrheal IBS in a less complex patient group. “


Most world health authorities say that many of the dozens of therapeutic benefits associated with aloe vera require further scientific evidence. This does not mean that the statements are necessarily inaccurate.

According to the United States National Center for Complementary and Alternative Medicine (NCCAMTrusted Source), part of the National Institutes of Health, aloe latex contains potent laxative compounds.

Products containing aloin, aloe-emodin, and barbaloin (components of aloe) were regulated by the FDA as over-the-counter oral laxatives. In 2002, the FDA required that all over-the-counter aloe laxatives be withdrawn or reformulated due to lack of donation.

Some studies have shown that topical aloe gel can help with abrasions and burns. However, NCCAM wrote: “There is not enough scientific evidence to support Aloe vera for any of its other uses.”
