Unwanted Side Effects of Tea Tree Oil
Skin Itching

The tea tree oil is considered one of the most effective medicines to combat skin problems like skin acne, blackheads, and many other ailments. The use of tea tree oil is deemed to be safe as it is all-natural, but some people have displayed acute problems with the application of oil on their skin. One common complaint among the consumer was a gradual increase in itching, redness of the skin, a stinging sensation, and in some cases mild to severe rashes.
The application of tea tree oil directly to the dry and broken skin was the main culprit here. As such doctors and dermatologists now advise against the direct use of oil on the dry and cracked part of the skin. If one still wants to test the effects of tea tree oil on their skin and wants to know whether it will be safe or not then they can apply the oil on a small patch of skin and observe its effects, if nothing happens then they can go ahead with further application of the oil on their skin.

But studies by various research groups have concluded that it may not be as secure as the accepted notions about the natural products. Constant usage of organic tea tree oil-containing mouth washers leaves behind a bitter taste.
It also leads to impairment and senselessness of taste buds on the tongue. Swallowing the tea tree oil also leads to increased toxicity of the body. It also leads to blood cell abnormalities, weakness, drowsiness, coma, and even hallucinations. It can even make one depressed after its ingestion.
Nasal Infection

The tea tree oil is also gets recommended for nasal polyps. Nasal polyps are the growth of the cells that align with the nasal passages. It is non-cancerous and quite painless. This leads to problems like snoring, pain in other areas of the face, and difficulty in breathing. The tea tree oil has been strongly suggested by physicians to help with nasal polyps up until now.
The tea tree oil can cause side effects before curing nasal polyps like making the nose run with fluid. The nose might burn after the application of tea tree oil. The oil once used on the polyps might swell it before shrinking and eliminating the polyp.

Impact on pregnancy
Unless swallowed or given with any mixture, there is no direct harm from tea tree oil to pregnant women. Pregnant women can use the tea tree for their skin or scalp without any repercussions as long as they are not allergic to plant-based products. But if one wants to be even safer, then they can stop the use of tea tree oil during the pregnancy period altogether. One should also avoid the use of the application of tea tree oil while breastfeeding.
Adverse effects on pets

The constant application of tea tree oil on their skin usually leads to muscle tremors. Though this can be treated easily with the help of proper treatment and veterinary experts, it is even better to avoid this situation altogether. The same adverse effect can get observed in humans with direct application of tea tree oil.
Damage caused to ears
The tea tree oil is continuously being used to treat ear infections. It is strongly advised to mix tea tree oil with some other oils like almond oils or olive oils to dilute the mixture. As the direct application of the oil to ears can cause swelling inside. One can then tilt their heads sideways to allow the mixture to move from one ear hole to another. But it is strongly advised not to do this as it may cause harm to the internals of the ear and do more bad than good.
Muscle Tremor

Tea tree oil can cause excessive drowsiness when a high amount of oil gets consumed.
Doubtful Quality
Tea tree oil goes through various refining processing factories and is packed in bottles. One cannot be sure if they are receiving pure tea tree oil or not. This casts a long question mark on the quality of the product and its usability. The pure tea tree oil may not be a virgin, and it’s just getting marketed as such. Diluted tea tree oil may not work correctly for our skin, and in some cases, it might even adversely affect our skin. As such one should be vigilant when trying to buy pure tea tree oil and make sure that it’s a reputed company.
The tea tree oil is just like any other nature-based product. It has many useful properties and is anti-viral, antibacterial, and anti-fungal. All these characteristics make it one of the most useful products. But just like not every product is perfect, it has its fair share of problems. One should consider their medical background and use any tea tree oil-based product whether diluted or pure with caution and carefulness.
