From wild ecosystem to the pharmaceutical use–exploring the traditional medicine and socio-cultural heritage of macrofungi from Pakistan

Abstract

ABSTRACT Medicinal macrofungi, like prized plants and animals, have dietary, therapeutic and commercial significance. This knowledge, anchored in the traditional healthcare system, warrants the identification of the most prominent species harbouring novel natural products. A traditional ethnobiological approach was adopted to collect ethnomycological data by interviewing 110 informants (95 men and 15 women) inhabiting 10 settlements in Bannu District, Pakistan. Visiting the remote nomadic sites revealed the most unique data of its type. This data was assessed and correlated with previous studies, comparing the standard numerical indices: informant consensus factor, fidelity level, use value, relative frequency of citation and Jaccard index. Tradition medicinal uses of 30 species of wild macrofungi (belonging to 19 genera and 12 families) are documented here. Podaxis pistillaris macrofungi was preference ranked with priority therapeutic uses, medicinally for stomach problems, as an antipyretic, for erotic uses, as an immune booster and as an antidiabetic; it is also nutritionally significant. Temperature and humidity are key factors for the growth of macrofungi generally in Pakistan (in spring and during the monsoon season), while the dynamic frequency of rain in the rainy season due to the impact of climate change cannot be neglected. Indigenous communities divided the ethnomycological potential of macrofungi into three main clusters: (a) edible macrofungi, for treating various disorders and as nutritional supplements; (b) non-edible macrofungi, medicinally important or just poisonous; (c) unknown or unused, without any known utility. Importantly, eight novel species with traditional uses are reported here, and the present work is the first ethnomycological study of macrofungi from Pakistan. This research aims to trace the traditional knowledge related to the naturally occurring medicinal macrofungi in the Bannu District, Khyber Pakhtunkhwa, Pakistan. Documentation of new medicinal species and novel uses of existing species reflect a healthy relationship between inhabitants of the Bannu District and wild medicinal macrofungi.
