New Findings: Scientific studies have raised concerns about the carcinogenic activity of aloe vera, specifically its whole leaf extract. The International Agency for Research on Cancer (IARC) has classified aloe vera whole leaf extract as having “clear evidence of carcinogenic activity in rats.”
Aloe Vera: A Natural Wonder
Aloe vera, often referred to as the “burn plant” or the “plant of immortality,” has been cherished for centuries for its medicinal properties. Its succulent leaves contain a gel-like substance that is used to treat a wide range of skin ailments, including burns, sunburns, and skin irritations. Its reputation for healing and soothing properties has made it a popular choice for topical applications.
However, aloe vera’s popularity has recently come under scrutiny due to concerns about its potential carcinogenicity. This raises a critical question: Could a plant known for its healing abilities also pose a cancer risk?
The Controversy Unveiled
The controversy surrounding aloe vera’s carcinogenic potential came to light through scientific research. Several studies have suggested that aloe vera, specifically its latex component, may contain substances that have the potential to cause cancer. Before delving into the specifics, let’s understand the different components of aloe vera and their uses.
Aloe Vera: More than Just a Plant
The Versatile Aloe Vera Gel
Aloe vera’s therapeutic properties primarily reside in its gel, which is extracted from the inner leaf. This gel is rich in vitamins, minerals, and antioxidants, making it a go-to remedy for various skin issues. It provides relief from sunburns, moisturizes the skin, and can even help in the management of skin conditions like psoriasis.

Aloe vera gel is generally considered safe for topical use and is widely available in the market. However, the real concern arises when we turn our attention to a less-known component of the aloe plant: aloe latex.
Aloe Latex: The Less-Known Component
Aloe latex is a yellowish substance found just beneath the outer leaf skin of the aloe plant. It is a bitter, sticky, and yellowish liquid that contains compounds known as aloin. Aloin is the key player in the controversy surrounding aloe vera’s potential carcinogenicity.
While aloe gel is used topically for its soothing properties, aloe latex has a different history of use. Traditionally, it has been used as a laxative and for its potential healing effects when consumed orally. However, the safety of aloe latex, especially in its unprocessed form, has come into question due to its potential link to cancer.
Aloe Vera and Cancer: What the Research Says
Evidence of Carcinogenic Activity
Scientific studies have raised concerns about the carcinogenic activity of aloe vera, specifically its whole leaf extract. The International Agency for Research on Cancer (IARC) has classified aloe vera whole leaf extract as having “clear evidence of carcinogenic activity in rats.” This classification has brought the carcinogenic potential of aloe vera into focus.
Let’s explore the key research findings on this topic.
– Aloe Vera Whole Leaf Extract
A study published in the National Institutes of Health indicated clear evidence of carcinogenic activity in rats exposed to aloe vera whole leaf extract. This revelation has prompted further investigation into the potential risks associated with aloe vera consumption.
Aloe Vera in Toxicity Studies
Despite the long history of aloe vera use, there have been limited toxicity or carcinogenesis studies reported in the literature. This lack of comprehensive research has raised concerns about the safety of aloe vera products, particularly when consumed.
Proposition 65 Listing
To add to the concerns, non-decolorized whole leaf extract of aloe vera is listed on Proposition 65, a list of substances known to the State of California to cause cancer. This listing has implications for product labeling and consumer awareness.

Safety Concerns: Aloe Vera’s Dark Side
The Controversy Over Aloin
The primary compound in aloe latex, aloin, has been the focus of scrutiny. Aloin is known to have laxative properties and has historically been used for its potential health benefits. However, the discovery of its potential carcinogenic properties has raised alarm bells.
Studies have indicated that aloin, particularly when consumed orally, may contain chemicals with the potential to cause cancer. This revelation has led to concerns about the safety of aloe vera products, especially those containing aloe latex.
Side Effects and Risks
Apart from the potential carcinogenicity, aloe vera latex consumption can lead to various side effects, including cramps and diarrhea. These side effects further highlight the need for caution when using aloe vera products, particularly in their unprocessed forms.
The safety of aloe vera has been a topic of debate. While some experts acknowledge the concerns raised by studies indicating carcinogenic activity, others argue that aloe vera is generally safe when used topically and that the risk of cancer is primarily associated with oral consumption of aloe latex.
Debunking the Myths
Aloe Vera as a Cancer Treatment
It’s important to note that there is no scientific evidence to support the use of aloe vera as a cancer treatment. While aloe vera has its merits when it comes to skin care and minor skin issues, it should not be considered a cure for cancer.
Aloe Vera and Intestinal Cancers
Carefully conducted studies by the U.S. government have concluded that there is “clear” evidence that aloe vera extracts may cause intestinal cancers. This finding underscores the need for caution when using aloe vera products, especially those containing aloe latex.
Recent developments in aloe vera research have raised questions about its safety and its potential as a carcinogen. The FDA’s analysis reporting “clear evidence of carcinogenicity” has added to the ongoing discussion. However, it’s important to consider all available evidence and expert opinions when forming conclusions.
In conclusion, aloe vera, a plant celebrated for its healing properties, is not without controversy. While aloe vera gel is generally safe for topical use and offers numerous benefits for the skin, concerns about the potential carcinogenicity of aloe latex have raised red flags.
Consumers should exercise caution when considering aloe vera products, especially those containing aloe latex. It is essential to read product labels, understand the source and processing of aloe vera ingredients, and consult with healthcare professionals when in doubt.
The balance between the benefits and risks of aloe vera remains a topic of ongoing research and debate. As we navigate this complex landscape, it’s crucial to stay informed and make choices that prioritize safety and well-being.
