Essential oils have gained popularity all over the world for their beauty, health, and therapeutic uses. Peppermint oil, a well-known essential oil, is used to alleviate digestive discomfort, muscle pain, and headaches.
While it has many health benefits, peppermint oil can cause adverse reactions if used excessively or improperly. Read on to explore some of the potential peppermint oil side effects and how you can use it safely.
What are the side effects of peppermint oil?
Although peppermint oil has a calming effect and other benefits, consuming it in high doses can cause some adverse effects. Here are the common disadvantages to note:
-
Digestive discomfort
While peppermint oil is known for its digestive benefits, excessive use can lead to heartburn, indigestion, or nausea. This occurs because peppermint oil relaxes the lower oesophageal sphincter, which may trigger acid reflux or worsen existing digestive conditions.
-
Drug interaction
Peppermint oil may interact with medications, including drugs for digestive issues, heart conditions, and blood thinning. Consult a healthcare provider before taking supplement products, especially if you are on medication.
Cyclosporine is one of the drugs that interact with peppermint. Peppermint oil slows down the rate at which the body breaks down cyclosporine, increasing the side effects of this drug.
-
Skin irritation
Directly applying undiluted peppermint oil to the skin may cause a burning sensation, redness, or irritation. To minimise skin sensitivity, dilute peppermint oil with a carrier oil before topical use. Apply the recommended dosage to avoid rashes and other skin issues.
Do not apply peppermint oil to an infant’s face because they can get severe side effects from inhaling the menthol in this oil.
-
Allergic reactions
Some individuals, including those with sensitive skin, respiratory issues, or pre-existing allergies, may be allergic to peppermint oil. Symptoms of an allergy include rashes, itching, or swelling, particularly around the face.
If you notice any reaction, discontinue peppermint oil use immediately and consult a healthcare provider. For safety, do a peppermint patch test by applying the oil to a small area to monitor the reaction.
-
Respiratory issues
Inhaling large amounts of peppermint oil vapours can cause breathing difficulties, especially in individuals with respiratory conditions. To avoid complications, use peppermint oil in moderation and have proper ventilation when using it for aromatherapy.
Conclusion
Even though it is an essential oil, improper or excessive use of peppermint oil can lead to unwanted side effects. You can enjoy its therapeutic properties while minimising the risks by following proper dilution guidelines and using it in moderation.
Consult a doctor before using peppermint oil, especially if you have health issues or are on medications. An appropriate medical insurance policy can cover the cost of consultations and treatments, ensuring financial protection and peace of mind.
