Cooking honey at 40 degree Celsius or more can cause negative chemical change that makes it taste bitter. Cooking destroys the potent health benefits of honey.
The study revealed that heated honey (>140°C) mixed with ghee produces HMF which may produce deleterious effects and act as a poison in due course (Ushnam cha samagrutham madhu marayati).
Turns out, honey should never be warmed, cooked, or heated under any condition. A study published in the journal AYU found that at a temperature of 140 degrees, honey turns toxic. When you mix honey in hot milk or water, it turns hot and turns toxic.
When you heat honey in any form, it turns toxic and can deteriorate your health. A study published in a prominent journal says that when honey is heated at a temperature of 140 degree Fahrenheit, or mixed into hot beverages, the otherwise beneficial food item turns toxic.
The simple answer is no. Adding honey to hot tea is nontoxic, despite a common belief. Many claim that heating honey in any way – in tea, for cooking – actually makes it so toxic that it will poison you. Again, an important distinction is between raw and processed honey.
Grayanotoxin Contamination
Consuming raw honey increases the risk of honey poisoning from grayanotoxins, which causes symptoms such as dizziness, nausea, vomiting and a drop in blood pressure. There are reports of people becoming sick after consuming raw honey, with grayanotoxins being the likely culprit.
As far as honey is concerned, you're in the clear, regardless of how long that cute little teddy bear bottle has been languishing in your kitchen: Expired honey will not make you sick (but if it has crystallized it might be a real pain to squeeze out into a cup of tea).
For best quality, store honey for up to 12 months. After that time, it remains safe but the quality may not be as good. Honey can become cloudy, crystallized or solidified but this is not a safety concern. The honey can be microwaved or heated in a pan of hot water to clarify or melt it.
When honey is getting bad, it develops a cloudy yellow color instead of a clear golden one — the texture then becomes thicker until it's grainy. Once it's finally considered “bad,” the color becomes white, and the texture gets hard. This whole process is because of the crystallization of honey for a long time.
Parents can help prevent infant botulism by not giving their baby honey or any processed foods containing honey (like honey graham crackers) until after their child's first birthday. Light and dark corn syrups might also contain botulism-causing bacteria, but a link hasn't been proved.
Do not refrigerate honey. Keeping your honey in the refrigerator preserves it but the cool temperatures will cause your honey to form a semi-solid mass, so this method of storage is not recommended.
A number of clinical signs have been associated with mad honey disease [3, 4]. Most often hypotension, cardiac rhythm disorders (first, second and third degree AV block, asystole, and sinus bradycardia), nausea and/or vomiting, sweating, dizziness and impaired consciousness have been observed.
Most bacteria and other microbes cannot grow or reproduce in honey i.e. they are dormant and this is due to antibacterial activity of honey. Various bacteria have been inoculated into aseptically collected honey held at 20°C. The result showed loss of bacterial viability within 8–24 days 27.
Honey goes through a change in the color, texture and loses its nutrient value, when cooked or heated. In fact, heating honey can turn toxic and change the texture like glue.
As per the National Center for Biotechnology, heating honey causes adverse effects. Cooking honey lowers its quality, and it loses essential enzymes and nutrients. In fact, heated honey has high chances of affecting the body and can be fatal as well.

According to the National Center for Biotechnology (NCBI), heating honey is contraindicated as it causes adverse effects. Cooking it deteriorates the quality and loses its essential enzymes and nutrients. Heated honey can actually produce delirious effects in the body and can be fatal at the same time.
