Misinformation! Dont buy it!

Im currently trying to get a refund from this app. At first glance it looks good but theres really no way to tell before buying it.
It gives some very bad advice on using peppermint oil with babies. This is an exact quote from the app:
Peppermint- Add one drop of peppermint essential oil to herbal tea and apply to temples, forehead, back of the neck, and shoulders. Then, apply 2 drops of oil on the tongue and another drop of oil under the nose and the stomach.
This is HORRIBLE, even DANGEROUS advice.
How can I trust the information on the rest of this app if it gives such misinformation? What about people who might not know any better? This is unacceptable.
