As a topical home remedy, a small patch of banana peel can be taped over a plantar or common wart and left on overnight. It can take approximately 3 weeks of doing this every night to see results, notes the University of Maryland Medical Center (UMCC).
While using the banana peel remedy, it may be useful to place a few drops of tea tree oil on the wart before the application of the peel. The appearance of warts is very common, especially in children. The main cause of different types of warts are different strains of HPV (human papillomavirus), as noted by UMCC.
