Aloe Vera Yellow Liquid: What You Need to Know

Ever noticed the yellow liquid oozing from your aloe vera plant and wondered what it is?

This mysterious sap, commonly referred to as aloin or aloe latex, often raises eyebrows.

But worry not; we’re here to demystify this unique aspect of the aloe vera plant for you.

Time to uncover the secrets of this enigmatic juice and its significance in the world of aloe vera, one of nature’s most cherished plants.

This is from one of my Aloe vera leaves. You an see the yellow liquid (aloin) dripping from it. Yes, it is very yellow!

To drain Aloe vera yellow liquid (aloin), I stand the leaf upright in water for several hours. This prevents the liquid from staining my pots or bowls and stops the aloe vera from oxidising when exposed to air, turning the liquid red. This red oxidation is due to certain compounds in aloe vera that change when exposed to the environment. Research suggests that the addition of certain substances, like alcohol, can prevent this oxidation, ensuring the purity and efficacy of aloe vera extracts, although I don’t add anything, just water.

What is the Yellow Liquid in Aloe Vera?

The yellow liquid in aloe vera is called “aloe latex” or “aloin.” It’s a sap found inside the plant’s leaves and is known for its strong laxative properties.. Check this link for more information.

Explanation of the yellow liquid (aloe latex)

The yellow liquid in aloe vera, known as aloe latex or aloin, comes from layers inside the thick green outer part of the plant. It has a strong, very bitter taste and a deep yellow-brown colour.

Many useful substances are found in this yellow sap – over 80 different types! One of them is called anthraquinone glycoside, acting as a very good laxative. But care needs to be taken with it because too much can harm you.

Laboratory tests show that the aloin in this yellow stuff can become toxic if misused. So, it’s best to avoid eating this part of the plant or including it when making home remedies like creams or lotions. Check below how I get rid of the aloin in Aloe vera (it is never 100% removed, but my method gets rid of most of it).

Presence of aloin, a powerful laxative

As we have seen, Aloe vera contains a yellow liquid called aloin, which is a strong laxative. This means that although it can help to relieve constipation and promote bowel movements, it is important to note that aloin can be toxic if ingested in large amounts. I’m not sure how much would be toxic to the body so I avoid it. I suggest you do the same, although you can also consult a doctor for more information on this.

That’s why I recommend to remove or avoid the yellow liquid when using aloe vera for consumption or topical application.

Long-term use of aloe latex as a laxative may lead to dependence and electrolyte imbalances.
- Prolonged ingestion of Aloe preparations can lead to adverse effects such as hypokalemia (a type of electrolyte imbalance) [source below].
In some cases, ingesting aloe latex has been linked to kidney damage and even cancer in animal studies.
- Aloe vera whole leaf extract showed evidence of carcinogenic activity in animals. In some cases, it was also linked to kidney failure [source below].
People with certain medical conditions like Crohn’s disease or haemorrhoids should avoid consuming aloe latex as it may worsen their symptoms.

How to drain the yellow liquid from the plant

Here’s a helpful video:

And here is how I do it:

Choose a Mature Plant: Select a mature aloe vera plant that’s at least a few years old for the highest concentration of nutrients in the gel.
Cut a Leaf: Using a sharp knife, cut off a leaf from the outermost section of the plant.
Trim the Leaf: Cut off the top and bottom edges of the leaf to make it easier to handle.
Drain the Aloin: Stand the leaf upright in a bowl and let it drain for between 2 to 24 hours. You can change the water a couple of times during this period to ensure all the aloin is removed.
Peel the Leaf: With the flat side down, use a knife to peel off the top layer of the skin.
Scoop Out the Gel: Once the top layer is peeled, use a spoon to scoop out the clear gel.
Store: If not using immediately, store the gel in an airtight container in the refrigerator.

Here’s a helpful video. It’s in Spanish but you’ll get the idea. This is how I do it, I leave the leaf 2h to 24h in water, depending on how long I’ve got to get started with the process of extracting the gel, as I’m usually quite busy. Also, I might change the water a couple of times.
