The phrase "proud flesh" refers to the excessive growth of tissue around a wound or injury. There are several synonyms for this phrase, including exuberant granulation tissue, hypertrophic tissue, and exuberant tissue. These terms all describe the same type of tissue growth, which can occur in both humans and animals. While this type of tissue growth is initially beneficial in the healing process, it can become problematic if it grows too much and impedes proper healing. Techniques such as wound dressings and debridement can be used to manage and reduce the amount of proud flesh tissue. It's important to address this issue promptly to ensure proper healing and prevent complications.
