These plants can be used to discover bioactive natural products in the form of antimicrobial proteins and peptides that may serve for the development of new pharmaceuticals. Such screening of various natural antimicrobial proteins and peptides supports the traditional knowledge of local users and it is a preliminary scientific validation for the use of these plants for the antibacterial activity. To promote proper conservation and sustainable use of such plant resources, awareness of local communities should be enhanced incorporating the traditional knowledge with scientific findings.
