Dr. Natural Healing Herb: Aloe Vera

Commonly Known about this Natural Healing Herb

Aloe vera’s use can be traced back 6,000 years to early Egypt, where the plant was depicted on stone carvings. Known as the “plant of immortality,” aloe was presented as a funeral gift to pharaohs.

Historically, aloe vera has been used for a variety of purposes, including treatment of wounds, hair loss, and hemorrhoids; it has also been used as a laxative.

Two substances from aloe vera, the clear gel and the yellow latex, are used in health products today. Aloe gel is primarily used topically (applied to the skin) as a remedy for skin conditions such as burns, frostbite, psoriasis, and cold sores, but it may also be taken orally (by mouth) for conditions including osteoarthritis, bowel diseases, and fever. Aloe latex is taken orally, usually for constipation.

Do We Have a lot Studies about This Natural Healing Herb?

There’s not enough evidence to show whether aloe vera is helpful for most of the purposes for which people use it.

What Have We Learned about This Natural Healing Herb? 

Aloe latex contains strong laxative compounds. Products made with aloe were at one time regulated by the U.S. Food and Drug Administration (FDA) as over-the-counter (OTC) laxatives. In 2002, the FDA required that all OTC aloe laxative products be removed from the U.S. market or reformulated because the companies that manufactured them did not provide the safety data necessary for continued approval.

There’s some evidence that the topical use of aloe products might be helpful for symptoms of certain conditions such as psoriasis and certain rashes.

There’s not enough high-quality scientific evidence to show whether topical use of aloe helps to heal wounds.

There’s not enough scientific evidence to support aloe vera for any of its other uses.

Do We Know the Safety of This Natural Healing Herb?

Use of topical aloe vera is likely to be safe.

A 2-year National Toxicology Program study on oral consumption of nondecolorized whole leaf extract of aloe vera found clear evidence of carcinogenic activity in male and female rats, based on tumors of the large intestine. Another study in rats showed that decolorized whole leaf aloe vera did not cause harmful effects. This suggests that a component called aloin, most of which is removed by the decolorization process, may be responsible for the tumors seen in rats fed nondecolorized whole leaf aloe vera. More information, including what products are actually in the marketplace and how individuals use different types of aloe vera products, is needed to determine the potential risks to humans.

Abdominal cramps and diarrhea have been reported with oral use of aloe latex. Also, because aloe latex is a laxative, it may reduce the absorption and therefore the effectiveness of some drugs that are taken orally.

People with diabetes who use glucose-lowering medication should be cautious if also taking aloe orally because aloe may lower blood glucose levels.

There have been a few reported cases of acute hepatitis in people who took aloe vera orally. However, the evidence is not definitive.
