First of all, make sure whether you are allergic to honey or not. If you are allergic to it, you should avoid it at any cost. If you try to consume it even after being allergic to it, you may have to face lots of consequences such as stomach upset, diarrhoea, sharp pain in the stomach, nausea, vomiting. You can also check the allergy by applying a small amount of honey on your skin. Take some amount and apply it to a small area of your arm. Wipe it after a few minutes. If the area turns red or else, if you experience itching or burning sensation, it means you are allergic to it.
Also, those who are allergic to honey shows severe symptoms if they consume or apply pure honey when compared to adulterated one. Some people tried unprocessed pure honey and were hospitalized as they were allergic to it. Thus, do not make haste in purchasing the purest honey. First, ensure that you are not allergic to it and then buy a good one.
Do not look at the prices while purchasing. Look for brands. For example, Dabur and Patanjali are good brands and sell original products. Similarly, there are many others known for their purity. Only buy the trusted ones. You can buy it from the beekeepers. They hardly adulterate it and also, they will charge you less. It will be unprocessed and raw one. Thus, it will be the purest.
Ways to identity pure honey-
1) Pure honey will always spread. Immerse a finger in honey. It never spills from the finger. On the other hand, adulterated honey spills easily.
2) Some brands try to adulterate honey by mixing a small amount of water in it. If the honey leaves a wet mark on blotting paper, it indicates that it has some amount of water in it.
3) Read the labels. If there are added colouring agents, artificial sweetening agents, artificial flavours, it is obvious that the honey is adulterated.
