Ethnopharmacological relevance: Processing cow ghee (clarified butterfat) with therapeutic herbs, i.e. ghrita, is recognized for augmenting the therapeutic efficacy of plant materials. Ashwagandha ghrita (AG) is an effective Ayurvedic formulation consisting of Indian ginseng, i.e., Withania somnifera (L.) Dunal, the main constituent used to treat infertility, weakness, gynaecological disorders, and general debility.
Objectives: The present investigation was undertaken to corroborate the ethnopharmacological claim of AG as 'Vajikarana Rasayana' for its aphrodisiac potential using bioinformatics (in-silico) and experimental (in-vitro and in-vivo) approaches.
Methods: AG was formulated as per the methods reported in Ayurved sarsangraha. AG was further subjected to HPLC, GCMS analysis, and biological (acute toxicity and aphrodisiac) assessment per the standard procedures. Thirty-eight bioactives of Indian ginseng were subjected to computational studies (molecular docking and network pharmacology) to confirm the plausible mechanism.
Results: AG was found to be safe up to 2000 mg/kg body wt., and it showed dose-dependent upsurge (p < 0.01 and p < 0.05, wherever necessary) in mount and intromission frequency, genital grooming, and anogenital sniffing at 150 and 300 mg/kg body weight suggesting aphrodisiac activity. In-vitro studies demonstrated significant relaxation of the Corpus Cavernosal Smooth Muscle at all concentrations in a dose-dependent manner. Furthermore, the results of molecular modelling studies were in agreement with the biological activity and showed interaction with phosphodiesterase-5 as a possible target.
Conclusion: AG exhibited an aphrodisiac effect and substantiated the traditional claim of Indian ginseng-based ghrita formulation as 'Vajikarana Rasayana'.
