For most people, peppermint oil is going to be a refreshing way to soothe gastrointestinal discomfort. However, it’s extremely dangerous in high doses, and ingesting the oil alone may damage your esophagus. There’s a lot to consider here, so get the advice of a healthcare professional before you start ingesting peppermint oil, and only take it in a capsule form on a full stomach. It is important to note that peppermint oil is only proven as a potential treatment for stomach discomfort. There’s no evidence it will treat any other condition or problem.

Question 1 of 5:

How do you take peppermint oil orally?

1
Enteric-coated peppermint oil capsules are the only safe option. Peppermint oil is too strong to drink on its own. The enteric coating on the capsules, however, prevents the oil from directly touching or damaging your esophagus. Most scientific research into the benefits of peppermint oil focus on taking the capsule form. ^{[1]

- Purchase enteric-coated peppermint oil capsules online or at vitamin stores.
- Always follow the dosing directions on the label. Generally, you can take 180-400 mg (0.2-0.4 mL) of peppermint oil in a single dose. It's safe to take up to 3 doses daily. ^{[2]

Don't drink peppermint oil since it can harm your throat. Peppermint oil is very powerful stuff. Consuming the oil directly relaxes your esophagus too much, which can lead to acid reflux and other gastrointestinal issues. While the oil can soothe your stomach, it’s going to cause irritation as it goes down. Taking enteric-coated capsules prevents these issues. ^{[4]
