Is Aloe Vera Safe To Drink?

Aloe vera has a broad history of medicinal use—but is the gel or juice of Aloe vera safe to drink?

Given the vast array of information available online, you can easily find arguments to support either side of any topic. My search on “eggs are good for you,” for instance, returns 246,000 results in praise of eggs. A search on “eggs are bad for you,” returns 84,100 entries vilifying them. Which is true?

Likewise, some reports say Aloe vera does not provide the extensive health benefits claimed by many, but may even be dangerous to consume. This is troubling. Reports of Aloe juice and Aloe gel as effective in the treatment of internal problems—from GERD  and prediabetes (metabolic syndrome) to immune system disorders—have made Aloe vera a popular product. Jugs of Aloe are on the shelves of supermarkets everywhere.

Should consumers be concerned about drinking Aloe vera?

We sometimes receive questions about Aloe from people who have come across an adverse report—like one from the National Institutes of Health (NIH). They want to know if Aloe is safe to drink. And we don’t blame them for wondering. After all, the NIH is one of the most trusted medical research centers in the world.

And to top it off, Aloe vera has been safely used as an herbal remedy for thousands of years. Stories abound of its. The legendary healing properties of the gel are well documented.

How, then, could the NIH say Aloe may be bad for you?

Researchers sometimes look for additional medicinal properties in parts of the plant that are normally not used. In the case of Aloe vera, that part is the outer leaf. Reputable providers of Aloe vera gel dispose of the outer leaf, keeping only the inner flesh. The researchers disposed of the inner gel and tested the outer skin instead.

Take a look at the NIH report, and you will see references to “Aloe latex” and “Aloe leaf extract.” These do not refer to the inner part of the leaf, which is commonly ingested, but rather to the outer portions.

Which part of an orange do you eat?

Many plant foods contain an outer layer of anti-nutrients for protection. You can distill the outermost portion of an orange peel to obtain d-Limonene, a phytochemical that acts as a natural pesticide. It protects the orange from insects.

The same can be said about the outside portion of an Aloe leaf. It contains a yellowish brown, bitter substance called “Aloe latex” (also known as “aloin” or “barbaloin”). Aloin is an anthraquinone glycoside, and is known to be a digestive irritant and laxative.

When you eat an orange, do you bite into it as is, or do you peel it first? How about watermelon? Nature did not intend for the rind of some plants to be eaten. Used properly, Aloe vera is a nutrient-dense superfood.

Like the orange, the outer layer of Aloe is sometimes ingested in small quantities. Many use Aloe peel as a natural laxative to relieve constipation.

The NIH researchers used a preparation of outer leaf anti-nutrients. They did not focus on the nutritious inner leaf; therefore no information concerning the use of Aloe vera inner leaf gel, as either a food or nutritional supplement, is obtainable from the NIH study.

In fact, the samples used by the NIH were created by grinding whole Aloe vera leaves, then removing the pulp (the good part) and keeping the outer leaf. The tests were conducted using the parts of the Aloe plant we discard.

In the initial 13-week study, it was demonstrated that whole-leaf Aloe vera extract produced goblet cell hyperplasia of the large intestines in rats. This makes perfect sense. The mucous producing cells would most certainly attempt to increase their ability to protect the body from a digestive irritant, like the preparation used in the tests.

Aloin, the phytochemical abundant in the outer green portion of the Aloe vera leaf, is known to cause diarrhea (as mentioned earlier, it is often used as a laxative). It is this usage of Aloe the report questions concerning safety. It has nothing to do with the inner filet of the Aloe leaf—which is the only part used in all Stockton Aloe 1 products.

Stockton Aloe 1 Aloe vera gel has been demonstrated by an independent laboratory to contain between 1 and 5 ppm aloin. In order to consume the referenced 1 gram of aloin per day, you would need to drink about 276 gallons of Stockton Aloe 1 raw Aloe vera gel every 24 hours. Even Aloe pioneer, Rodney Stockton (who was in excellent health into his nineties) only drank a glass or two of Aloe gel each day.

That said, consumers should know that many Aloe drinks are “whole leaf” and may indeed cause stomach upset. The highest grade of Aloe products are taken from the inner leaf only. Moreover, because of modern filtration and processing techniques, even whole leaf Aloe drinks are likely to have very low aloin concentrations, compared to the preparation given to the rats in the government study.

Is Aloe vera safe to drink?

Most certainly—if it is prepared correctly from the plant’s inner leaf gel.

    Hello !
    My dad is 92 years old. He suffers of constipation. He also has tummy aches often. I am wondering if this drink will be safe for him?

    Thank you so much in advance

      When it comes to foods such as the aloe from Haley Nutrition, after 6 months, age is not really a factor that will determine it’s safety.

    Just wondering if your aloe is safe during the last trimester of pregnancy. I read that it can cathartic and cause uterine contractions. Is this the outer portion of the leaf that has these properties?

      It is the outer portions that can cause uterine contractions. The inner portion is more like a food… though a “super food”. Yet at the same time, the FDA warning regarding raw unpasteurized products still applies… though we have never found pathogenic bacteria in our aloe.

      Hi Dr. Haley’
      The first time I used your product, I didn’t let it thaw completely so my first glass was thin liquid with no gel and very bitter.
      Are there any safety concerns in drinking this thin liquid component In a concentrated form ?
      It was very bitter as opposed to when I drank the gel when it was thawed which was fairly tasteless.
      Thank you

        There are no concerns. Even a few PPM aloin is extremely bitter which is what you likely experienced. However we calculated it to hundreds of gallons worth of our aloe vera would have to be consumed in a day to reach the dangerous levels of aloin – you will drown in our aloe vera before you consume too much aloin.

    Hi Dr. Haley, does drinking Aloe Vera gel everyday lower red blood cells/iron levels and white blood cells? Please explain.
    Last December, I bought organic whole aloe leaf, I only use the white part inside with no green part. I used 1 inch per day and blend that 1 inch with 1cup of water and drink it. I did that for several weeks. In January 18 2010, my CBC showed lower white 1000 and red blood cell/iron was 9. Six months prior to drinking aloe gel, my CBC was normal. I never had these readings before in my life. Does drinking the aloe lower my iron and white blood cell? I plan on drinking Stockton Aloe1 so I want to make sure. Thanks a lot.

      I was unable to find research suggesting aloe vera lowers blood cell counts, but did find this which suggests it is beneficial for anemia, lymphocyte % may increase, and neutrophils % decrease

        Thank you so very much for this wonderful article Dr. Haley. It clarifies a lot for me and answered my questions. God bless you.

    I’ve been drinking Aloe Vera with Coconut water lately. It’s nice after a long bike ride.


    The freeze thaw thing seems a little confusing. I am wondering if you would receive the same benefits freezing the Aloe into Ice cubes then mixing the frozen cubes into a smoothy for ingestion.



      Yes, however, when in a cube form, there is usually more surface area exposed to the air… which means more freezer burn.

    Hi, are you familiar with Frei Zago Romanos Aloe Aborescens recipe… and the research and book he wrote about “Cancer can be cured” … point is… in the recipe they mix the whole leaf + honey and a 1% alcohol.
    The recipe is recommended on Cancer Tutor. However I was wondering how this can be… if NIH found out that the aloin is carciogenic. Is it safe to take his recipe, as it has whole leafs in it`?


      NIH found out that large amounts of aloin extract (outer leaf only) causes the tissues that secrete mucous to increase in size… probably to secrete more protective mucous because only the irritant was given. This adaptive change is called “cancer”. It was a study to show that aloin (by itself) could cause problems. They wanted to demonstrate that aloin was NOT a safe laxative. The recipe you are referencing uses “whole leaf”… includes the healing soothing aspect of the plant which should balance the outer leaf part… however, research has never been done on whole leaf as it relates to intestinal cancer.

    It is a yes or no question. My kid just drank some and I need to know if I should take her to the hospital and this page was no help.

    I slice and soak whole aloe leaf in a bottle of water, to be taken every morning before food. How safe or unsafe could that be pls.

      I disagree with using it this way, but many do without problems. So it seems pretty safe.

    Tried Aloe Vera Juice for the first time. 5 hours later had bad stomach pains and violent diahrhea. Became dehydrated, couldnt eat and had terrible muscle cramps. Two days later still feeling after effects. But on bright side i am down 5 lbs.

      The key word was “juice”. Aloe “juice” products tend to be either “whole leaf” and / or include other ingredients. Pure Aloe gel does not have that effect.

    Dear Dr. Haley,
    I grow Aloe Vera in my yard. Since you are not promoting your product and trying to help:
    Question #1 : Is it safe to ingest pure Aloe Vera gel spooned out of the skin? If so what is the maximum amount a person should ingest a day ? (in ounces, teaspoons or milligrams please) I know it vries by height weight and over all health of a person.
    Question #2 how much pure Aloe Vera gel spooned out of the skin will provide 1 gram of plant sterols?(in ounces, teaspoons or milligrams please) .

    2 grams (2000 MG) of plant sterols is required each day for people with high cholesterol.

    I recently learned that among other benefits, Aloe Vera gel is a good source of plant sterols, which reduces LDL, and good for preventing type 2 diabetics and the production of insulin for diabetics.

      Regarding how much you can drink… it depends on your specie, how you extract the gel (how much aloin gets in your gel) and a few other factors… find out more here:

      Regarding plant sterols… I don’t know. I know lots of people with HBP and diabetes use aloe vera and claim it helps them… but I am unfamiliar with how much and whether the benefits are from plant sterols. I might run that one by the

    Your comparison of aloe leaf to orange peel, or d-limonene has me wondering if that is a good comparison. I have used organic d-limonene for years to help with stomach issues such as gastritis, it works, even the Life Extension Foundation has a d-limonene product for that reason. I don’t have them at hand, but I have read many positive scientific reports on the benefits of consuming d-limonene. Here is the product I use:
    I would love to hear your opinion on this, and if it is still negative, could you provide me with any information verifying d-limonene’s negative effects health-wise?

      I just re-read… to make sure it was a good comparison. I feel good about it. You see, in the study, they gave rats mega-doses of of aloe vera outer-leaf extract. d-limonene may have some medicinal benefits in small amounts. It probably was not intended to be eaten as an isolate apart from the orange though. d-limonene is NOT a “whole food”. Much in the same way that large doses of d-limonene will cause upset stomach… the very same symptom people use d-limonene to relieve. The point, however, is that in the study, they wanted to show “aloin” to be dangerous… and accomplished that by giving rats large amounts.

    Do you know why the NIH only tested the outer part of the leaf?

      From what I understand, some companies were putting the outer leaf sap in powder form… into capsules to sell as a laxative.

    I’m trying to find answers after overdosing on aloe water. My liver went into shock and it was presumed end stage cihrrosis. After a year in the transplant list at Mt Saiani in NYC my liver suddenly turned around. Could my sickness stem from this???? I was not sick until drinking pint glasses of pure aloe water. It came hard and fast. Please help me in trying to find answers.

      I am not sure what “aloe water” is. If it is pure water extracted from aloe, certainly it was not the cause. But if you put a slice of aloe leaf in water to make “aloe water”, then maybe…

        So doctor you are saying that the gel inside the plant is good but the leaf itself is only used in small amounts when you are in need of a quick digestive cure. But the jail itself is good and readily used for all type of ailments and illnesses am I right and that assessment

          The outer leaf in small amounts might be a gut flush… but not a cure…
          Regarding aloe used for all types of ailments and illnesses… it is true that people use aloe vera for many of their illnesses… but I can’t say that the gel could be used for illnesses even if people do use it for illnesses. There is some science suggesting it could help some conditions. A search on will give better scientific insight.

    Can aloe vera juice be used to aid in healing hernias?

      It can support the body during healing… but aloe vera doesn’t heal hernias.

        I’m trying to find answers after overdosing on aloe water. My liver went into shock and it was presumed end stage cihrrosis. After a year in the transplant list at Mt Saiani in NYC my liver suddenly turned around. Could my sickness stem from this???? I was not sick until drinking pint glasses of pure aloe water. It came hard and fast. Please help me in trying to find answers. After closer examination, I see that basically this site is selling stuff that almost killed me., I’m sure I won’t get answers and my post with questions will be deleted. Hopefully not ?

          Julie, this site is for the benefit of the people… this is now the 4rd post of yours on this same page that I am approving. I only deleted the one that was an exact duplicate of your previous post. But I am certain that what we manufacture was nothing like whatever you drank. So please tell us exactly what “aloe water” is.

    Thank you for the information. Are you familiar with fatty liver condition known as N.A.S.H.? I was diagnosed last year. I like that the aloe water seems to help me with a sensitive stomach but want to be careful with my liver. Are you aware of any studies that deal with aloe water & fatty liver?
    Thank you again.

      I am not aware of any studies related to this.

        Be careful!!!! I was hospitalized for a year after overdosing in aloe water. It was after my daughter’s tragic death and I was drinking a lot of aloe water thinking I was doing good staying away from alcohol. No one told me that it’s small doses only

          Please share what “aloe water” is for the benefit of anyone that might see this.

    Hello Dr. Haley,
    My name is Rosemary and we spoke last week. I would like to set up a time to come and see you. My contact number is 305-751-8732. I look forward to hearing from you.
    Thank you,

      Please do call during our open hours and schedule an appointment.

    do think that soaking Aloe Vera leafs in water for a few minutes is enough to get rid of the Aloins ?

      That is what we do… and we test between 1 and 4 ppm aloin… which is extremely low… so, yes.

    Hi , its me from Nepal ,i’m also interest to ask some question hope i get the answer from you .I’m also suffering from constipation problem from long period of time when i’m 15 years old the constipation problem started but the time there is no any stomach pain problem inside ,only one thing that my whole body fell fatigue and felling hot inside .And that time i took different type of Aurvedic medicine and taking Aciloc 150 many time but can’t solve my problem .

    when i’m 24 somehow searching in internet n different other person told Aloe-Vera was good for stomach n intestine problem, so at that time its a period of winter starting here in nepal(Nov 2013) I bought from the market n drink three times a day morning-afternoon-evening at least 2 month .when i’m taking those juice at that time its fine i have no any constipation problem but when 4-5 bottles i finish ,i’m good n no any constipation problem but i severe problem of VITAMIN D deficieny and need of sunlight and taking a lots of protein (ie egg,meat …) After 2 years I’m good in vitamin d but having same condition in constipation ,these 2 years i’m far from these ALOE-VERA juice, so these days watery in mouth and wound inside mouth and having constipation again and acid comes in throat .How can i cure permanently ,Can i again using Aloe-Vera does it good for my health ???

      The yellow part of the leaf close to the trunk would have a lactive effect. There is one thing you should investigate though, the yellow part contains aloin wich would be a carcinogenic according to the FDA. I trust the FDA as any other three letter government organisation which is zero, so search in that direction. It might just be that it’s just bogus and then you have the perfect natural cure for your ailement.

      IT is very confusing. It worked for this person and then it didn’t why not? Either it is good for you or it is not.which one is it?

      are u having sufficient water (3-5 lts) ?
      looking at ur comments, u need to consult a doctor.

    Can you mix it with something so that it will taste better?

      To one person, it has no flavor at all. To another, the same bottle is bitter. To the one that tastes bitterness, I suggest a tad bit of stevia leaf extract. To the one that can’t stand the texture, shake in a little tart cherry concentrate… think “un-cured jello”.

      Mix it with dialuted buttermilk, pinch of salt and half tea spoon of lime juice. It’s a great drink to taste then.

    It may be safe, but your taste buds might warn you differently! It is not likely to be the base of the next big cocktail sensation!
