Verrucae vulgaris are infectious keratotic lesions caused by the human papillomavirus (HPV), frequently impairing an individual's quality of life, mainly when situated on the facial region. Verruca vulgaris constitutes a prevalent dermatological issue with diverse repercussions for those affected. The interaction among HPV, the immune system, and treatment methods requires a sophisticated comprehension of this illness. The need for more proficient management of this ailment constitutes a considerable challenge for the healthcare industry. Topical corticosteroids, cryo-therapeutic techniques, laser-based treatments, and immunotherapeutic modalities, including photodynamic therapy, are recognized as costly alternatives. Siddha external medicine offers a therapeutic strategy that employs suitable methodologies.
