The Surprising Health Benefits of Keeping an Aloe Vera Plant at Home

That spiky green plant sitting on your windowsill may be doing more for you than you realize. Long prized as a natural remedy for sunburns, aloe vera has drawn attention for a range of potential health benefits — from improving air quality in your home to supporting gut health and oral care.

Here’s a closer look at what this common houseplant has to offer and what experts say about its uses.

What Makes Aloe Vera Special?

Before diving into the benefits, it helps to understand what’s actually inside those thick, fleshy leaves. According to Medical News Today, “Aloe vera is known for its thick, pointed, and fleshy green leaves. Each leaf contains a slimy tissue that stores water, making the leaves thick. This water-filled tissue is the ‘gel’ that people associate with aloe vera products.”

That gel isn’t just water. As Medical News Today notes, “The gel contains beneficial bioactive compounds, including vitamins, minerals, and antioxidants.”

It’s this combination of bioactive compounds that has made aloe vera a popular ingredient in skin care products, health drinks and home remedies for generations.

Cleaner Air in Your Home

One of the lesser-known perks of keeping an aloe vera plant indoors is its potential to improve air quality. Aloe vera plants, along with other houseplants, increase oxygen levels and absorb carbon dioxide.

However, it’s worth noting that this isn’t a trait unique to aloe. Jane Wilson, executive director of the International Aloe Science Council, told USA TODAY that any houseplant can do the same.

Still, the air-quality benefits of indoor plants — aloe included — go beyond just oxygen. According to USA TODAY, “Plants, including aloe plants, can also remove toxins from the air we breathe.”

That claim has scientific backing. In 1989, NASA published a study that found that indoor plants can eliminate chemicals like formaldehyde and benzene from the air. For anyone looking for a simple, natural way to freshen up their living space, an aloe vera plant on the counter or shelf could be a good place to start.

A Go-To for Burns and Skin Irritation

Perhaps the most well-known use of aloe vera is as a topical treatment for burns and minor skin issues. If you’ve ever snapped off a leaf and rubbed the cool gel on a sunburn, you already know the soothing relief it can provide.

According to Plant Perfect, the plant’s uses are extensive: “The soothing gel inside an Aloe vera leaf can be used for more than just sunburns! Cut off a spiky leaf, scrape out the gel with a spoon, and apply the fleshy gel to the affected area of cooking burns, sunburn, eczema, or abrasions for relief.”

That said, there are important limits to keep in mind. Plant Perfect cautions that “while Aloe vera seems like a ‘soothe-all,’ it should not be used on severe burns or broken skin.”

For everyday kitchen burns, mild sunburns or minor skin irritation, however, having an aloe vera plant within arm’s reach can be a practical and convenient home remedy.

Potential Heart Health Benefits

The benefits of aloe vera may extend well beyond the skin. In an article for WebMD, R. Morgan Griffin and Stephanie Watson report that, when ingested, “This plant extract might help lower levels of unhealthy low-density lipoprotein (LDL) cholesterol and fats called triglycerides while boosting heart-healthy high-density lipoprotein (HDL) cholesterol.”

How does it work? According to Griffin and Watson, “Researchers think aloe vera works by reducing the amount of cholesterol that the intestines absorb.”

For readers unfamiliar with cholesterol terminology, LDL is commonly referred to as “bad” cholesterol, while HDL is known as “good” cholesterol. The potential for aloe vera to shift that balance in a favorable direction is noteworthy, though as the WebMD article frames it, the evidence is still emerging. Researchers “think” they understand the mechanism, rather than stating it as established fact.

Gut Health and Digestive Support

Another area where aloe vera has attracted attention is digestive health, particularly for those dealing with constipation. However, this is one area where the science comes with significant caveats.

Griffin and Watson explain that “Aloe vera juice and aloe latex are promoted as a treatment for constipation. Aloe contains substances (such as barbaloin) that act as laxatives. Barbaloin increases the amount of water in the intestine, which could make poop easier to pass and help digested foods move more easily through the intestines.”

They note that “Aloe juice and latex used to be in over-the-counter constipation drugs.” However, there’s an important safety warning: “But because aloe can cause painful cramps and other side effects, the FDA does not consider it safe to use as a laxative.”

That distinction matters. While aloe vera juice is widely available in grocery stores and health food shops, anyone considering it for digestive purposes should be aware of the FDA’s position on its laxative use.

Oral and Dental Health

One of the more surprising potential benefits of aloe vera involves oral health. According to Healthline, a “study found that an aloe vera mouthwash effectively reduced the severity and pain related to oral mucosities — a common side effect of chemotherapy and radiation treatments — in individuals with head and neck cancers.”

Additional research points in a similar direction. Healthline reports that “a study in 64 people with cancer found that using an aloe vera mouthwash solution 3 times daily for 14 days helped reduce the occurrence and associated pain of chemotherapy-induced stomatitis, which is an infection in the mouth.”

Beyond cancer treatment side effects, there may be broader dental applications as well. According to Healthline, “It’s also speculated that aloe vera mouthwash could help reduce dental plaque and manage pain and swelling following oral surgery.”

The use of “speculated” is important here — while early research is promising, these potential dental benefits are still being explored.

The Bottom Line

From cleaner air and soothed skin to potential support for heart health, digestion and oral care, the humble aloe vera plant packs a surprising number of potential benefits into its thick, fleshy leaves. Some of these uses — like treating minor burns — are well established in everyday practice, while others — like cholesterol reduction and dental plaque management — are still areas of active research.

What’s clear is that whether you keep one on your kitchen counter for burn relief or simply enjoy it as a low-maintenance houseplant, aloe vera offers more than meets the eye. Just remember: for serious burns, broken skin or digestive concerns, it’s always wise to consult a health care professional rather than relying solely on a home remedy.
