ABSTRACT
Ethnopharmacological relevance: Processing cow ghee (clarifed butterfat) with therapeutic herbs, i.e. ghrita, is
recognized for augmenting the therapeutic effcacy 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 confrm 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
sniffng at 150 and 300 mg/kg body weight suggesting aphrodisiac activity. In-vitro studies demonstrated sig-
nifcant 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’.
1. Introduction
Withania somnifera (L.) Dunal, often known as Ashwagandha or In-
dian ginseng, is a member of the nightshade (Solanaceae) family and, in
Ayurveda (traditional Indian systems of medicine), it is revered as
Rasayana. The effectiveness of Rasayana treatment has been praised for
its ability to bestow superior Rasas and Dhatus on the body and to pro-
mote optimal health (Gurav et al., 2020). The plant is widely used in
various traditional systems of medicine to treat neurological disorders,
