Traditional medicinal plants used in India demonstrated strong antifungal effects against fungal pathogens associated with dermal infections, with garlic, acalypha indica, and lawsonia inermis extracts showing the most promising antifungal activity. This research provides evidence for the potential use of natural plant extracts as alternative antifungal therapeutics for skin infections.
A broad spectrum of medicinal plants was used as traditional remedies for various infectious diseases. Fungal infectious diseases have a significant impact on public health. Fungi cause more prevalent infections in immunocompromised individuals mainly patients undergoing transplantation related therapies, and malignant cancer treatments. The present study aimed to investigate the in vitro antifungal effects of the traditional medicinal plants used in India against the fungal pathogens associated with dermal infections. Indian medicinal plants (Acalypha indica, Lawsonia inermis Allium sativum and Citrus limon) extract (acetone/crude) were tested for their antifungal effects against five fungal species isolated from skin scrapings of fungal infected patients were identified as including Alternaria spp., Curvularia spp., Fusarium spp., Trichophyton spp. and Geotrichum spp. using well diffusion test and the broth micro dilution method. All plant extracts have shown to have antifungal efficacy against dermal pathogens. Particularly, Allium sativum extract revealed a strong antifungal effect against all fungal isolates with the minimum fungicidal concentration (MFC) of 50-100 mu g/mL. Strong antifungal activity against Curvularia spp., Trichophyton spp., and Geotrichum spp. was also observed for the extracts of Acalypha indica, and Lawsonia inermis with MFCs of 50-800 mu g/mL respectively. The extracts of Citrus limon showed an effective antifungal activity against most of the fungal strains tested with the MFCs of 5-0800 mu g/mL. Our research demonstrated the strong evidence of conventional plants extracts against clinical fungal pathogens with the most promising option of employing natural-drugs for the treatment of skin infections. Furthermore, in-depth analysis of identifying the compounds responsible for the antifungal activity that could offer alternatives way to develop new natural antifungal therapeutics for combating resistant recurrent infections.
