Removing nebula

Removing nebula (known in Traditional Chinese Medicine as Tui Yi) refers to a therapeutic action or functional category of medicinal substances used to clear corneal opacities and improve vision. It is not a specific biological target molecule, such as a single receptor or enzyme, but rather a clinical indication for treating ocular disorders including keratitis, cataracts, and pterygium. Traditional remedies classified under this category, such as Cicadae Periostracum and Pearl powder, are traditionally described as clearing 'liver fire' and 'wind-heat' to restore clarity to the eye. Modern pharmacological research suggests these substances may work by modulating inflammatory pathways (e.g., NF-κB, PI3K/Akt) and reducing oxidative stress in ocular tissues. While the term does not correspond to a canonical human protein, the gene 'nebula' exists in Drosophila (orthologous to human RCAN1), though it is unrelated to the TCM therapeutic phrase.

Traditional Chinese Medicine principles involve clearing liver heat and dispelling wind-heat to restore corneal transparency. Pharmacological evidence suggests these treatments reduce ocular inflammation, inhibit oxidative damage, and promote the resolution of corneal scars.
