Aloe vera: Benefits and medical uses

Oct 31, 2024

Many people use Aloe vera and its extracts for dietary and topical means. While it may have positive effects in specific instances, not all of Aloe vera’s reported benefits are backed by science.

There are several claimed therapeutic properties of Alove vera. In this article, we will examine some of these claims and investigate the research behind them.

Aloe vera is a deep green, cactus-like plant that grows in hot climates. Many of its reported health properties relate to the gel that is extracted from the core of its leaves.

Aloe vera is used today in:

Aloe vera has several reported benefits, ranging from the treatment of inflammatory skin conditions to promoting gastrointestinal health.

However, many of these claims are based on anecdotal evidence, or small studies. As such it is difficult to draw conclusions about its efficacy in many instances.

People should speak with a doctor before trying aloe vera as an alternative treatment, and its use should never take the place of doctor-recommended medicinal treatments.

Limited research suggests that topical aloe vera products and mouthwashes may be effective in promoting wound healing in the mouth and reducing symptoms of gum disease.

For example, an older 2016 study found that regular use of aloe vera-containing mouthwash was effective in pain and swelling management following molar surgery.

Similarly, a small 2018 study found that topically applied 1% metformin and aloe vera gel aided in the treatment of chronic periodontitis.

A 2020 review also found several incidences of topical aloe products aiding in gum disease, although many of the referenced studies were of low quality or older age.

Several studies have assessed the use of topical alove-containing ointments for wound healing in burns, cuts, and ulcers.

A small 2024 study found that topical application of aloe vera gel may be a safe and effective adjunctive therapy for diabetic foot ulcers. Although researchers did note that further study was necessary to fully assess its efficacy.

Similalry, a 2022 review found that aloe gel application led to “significantly faster time to healing” in second degree burns.

Aloe vera extract is a common component of many skin products. People often promote its use for the treatment of acne, psoriasis, and other dermatological conditions.

One 2021 study supported the use of aloe vera-containing products as an adjunct therapy for acne compare to baseline.

Aloe vera may have anti inflammatory properties, which may reduce visible signs of inflammatory skin conditions. For example, topical aloe vera ointments may help to reduce skin discoloration and scaling associated with psoriasis.

Many people claim that the antiinflammatory properties of aloe vera can help treat inflammatory bowel conditions such as Crohn’s, ulcerative colitis, and inflammatory bowel syndrome (IBS). However, evidence is lacking.

A 2023 animal study found that regular consumption of aloe vera extract mediated inflammatory response in ulcerative colitis, while a 2018 review concluded that aloe vera may be beneficial in treating some IBS symptoms.

Aloe vera is a popular component in many alternative and adjunct therapies. There is limited research to suggest it may aid in wound healing, dental health, and the treatment of several inflammatory skin and bowel conditions.

However, more research is necessary to assess its efficacy in these areas fully, and people should consult a doctor before using any alternative therapy.
