Enteric cover in capsules of peppermint oil

Can you explain me that why is not advisable the enteric cover in capsules of peppermint oil?

R/ The Peppermint oil capsule does not have the enteric coating of medicinal products and so dissolves in the stomach – not just in the lower intestine. It is designed to be anti-spasmodic and smoothing for the stomach and its effect is also active lower down in the small intestine.

Is pharmaceutical grade?.Yes.
