If you are using aloe vera juice for your gargle, then you should be able to use it without dilution.
There are many possible recipes for aloe gargles. One is to combine ¼ cup of witch hazel, ¼ cup of aloe vera gel, 1 teaspoon of vegetable glycerin, 1 teaspoon of lemon juice, and 10 drops of tea tree oil. Put them inside a sealable container and shake well. [3] X Research source Don’t swallow the gargle. Gargles are not usually supposed to be ingested. While swallowing some aloe vera may be safe, some ingredients such as tea tree oil can be toxic when taken internally.
Once you have exhaled all of your air, either inhale again through your nose or spit out the gargle and then take in a new breath.
Some people take aloe remedies internally – in other words, they eat it in very small amounts. One recipe is to put aloe gel inside of a jar with honey, onions, green apples, lemon, and witch hazel. Let the mixture sit for a long time. Then, take up to 1 tablespoon at a time, three times per day. [6] X Research source Even if used in small amounts, pure aloe vera should relieve some of your discomfort while not exceeding the recommended daily dosage.
There needs to be more research done on the medical effects of aloe vera. Along with constipation, there is some evidence that it could have carcinogenic properties when ingested in large amounts. [8] X Research source
Pure aloe vera is typically available commercially at grocery stores, pharmacies, and online retailers.
A commercial product like aloe vera juice can be very helpful for full strength application but it also can be used in a diluted form.
To harvest aloe vera gel, begin by cutting off one of the leaves at its base. Then cut open the leaf along its length. Once you pull back the outer layer of the leaf, the gel inside will be exposed and it can be scraped out. Growing aloe vera at home is relatively easy. You can grow it indoors in a pot with minimal care. In certain climates, specifically those that never get below freezing, you can also grow it outside. [9] X Research source
