What can happen if the essential oil is used too often?

Essential oils are advertised as a “miracle” for many human problems, from skin care to mental health. However, these essential oils are not as harmless as many people think. It is true that essential oils have a pleasant, relaxing scent, but the marketing technology has painted too many real benefits, while downplaying their inferiority. It’s important to stay healthy, but be aware of the following potential risks of essential oils and how to safely use them.

Toxicity spreads quickly and it only requires a small amount of essential oil to be life-threatening. It can lead to vomiting, lung damage, and central nervous system depression. The most dangerous oil is eucalyptus, a few drops can cause nausea, stomach pain and seizures. 80% of poisoning cases are caused by accidental, mistaking essential oils with liquid medicine such as cough syrup, some people still use it by mouth due to false information.

Makes the male chest area develop

There is a phenomenon called gynecomastia – the development of “male breasts”. Although rare and often without an obvious cause, it can be triggered by lavender and tea tree essential oils.

One study has shown that essential oils are often the cause of enlarged breast tissue in young guys. It involved 3 boys who did not share the same bloodline, but suddenly appeared on the chest and used skin care products extracted from lavender and tea tree oil. As it turns out, essential oils can mimic female hormones and suppress male behavior. This disrupts the overall hormonal and endocrine balance of the body.

Be sensitive to the sun

Some essential oils are photosensitive, which means they increase the skin’s vulnerability to sunlight. Citric and bergamot essential oils are the two most dangerous. Many citrus fruits contain a compound called furocoumarin, which can cause chemical burns when exposed to sunlight. In extreme cases, even a few minutes in the sun can cause blisters and sunburn.

Skin problems

Note using essential oils properly

The problem with essential oils is largely due to the manufacturer’s admonition that they are natural products that cannot be dangerous, when in fact they are not.

If you dismiss the hype of advertising, it can be seen that essential oils are not a panacea, but also not dangerous. Some oils have insect repellant, anti-parasitic, antiseptic properties, aid with hair problems, and their gentle scent helps reduce stress. However, when misused, they can lead to all of the above.

So, before using essential oils consult your doctor. Then, test your body’s response to them by taking a small amount of oil on your arm or leg. This way people can check for allergies. And finally, remember that essential oils are not overused.
