  "abstract": "Among the vast variety of proposals put forward by the community to resolve tree-level unitarity violations in Higgs inflation models, there exists the concept of self-healing. This mechanism helps cancel out tree-level violations for elastic scattering processes by summing over successive vacuum polarization loop corrections. In this comment, we shall see how self-healing is a manifestation of the optical theorem for a theory tailored to behave in a certain way.",
