Topical Sandalwood Oil for Common Warts

The purpose of this study was to evaluate the effectiveness of sandalwood oil for cutaneous viral warts caused by human papillomavirus. Sandalwood oil was applied topically twice daily for 12 weeks to cutaneous warts on any area of the body. Data collected at each visit included measurement of wart size, photograph of the warts, and documentation of treatment compliance and any adverse reactions. Ten subjects were enrolled and received treatment. At the end of the study, 8 of 10 (80%) had complete resolution of all treated warts. The remaining 2 subjects had improvement rated as moderate (25% to >90%). There were no complaints of skin irritation, erythema, itching, peeling of skin or scarring, pain or discomfort, or other adverse events reported. Sandalwood oil appears to be effective in the painless treatment of cutaneous warts caused by human papillomavirus.
