Study summary

Nonclinical studies have shown sandalwood oil to have anti-inflammatory, anti-fungal, antiviral, and anti-bacterial activities. Previous clinical studies have shown East Indian Sandalwood oil to be promising as a treatment for common warts in adults and children.

The primary objective of this study is to evaluate the efficacy and safety of 10%, 20%, and 30% East Indian Sandalwood Oil (EISO) ointment compared with the ointment placebo administered twice daily (bid) for 12 weeks for the treatment of common warts (Verruca vulgaris).
