Topical cream
Saleem et al. reported in 2008 on an herbal cream preparation using a standardized extract of M. azedarach flowers that displayed strong antibacterial activity against cellulitis, pustules, and pyogenic infections, and other conditions in clinical trials in children under the age of 10 years in four different villages in Pakistan. Subjects with bacterial infections anywhere on the body were divided into three groups, one treated with M. azedarach cream, one with placebo (negative control), and one with neomycin (positive control). Each treatment was applied twice daily for 15 days. The investigators observed that the healing effects of M. azedarach were similar to those rendered by neomycin.7
Conclusion
Not only has M. azedarach been used in several traditional medical systems, but its uses have consistently included cutaneous indications. Its most convincing modern application may be for head lice, but recent evidence and traditional uses suggest that this versatile plant may indeed warrant a more prominent role in the current dermatologic armamentarium. Future research is needed, and should provide some interesting answers.
