The advancement of phytochemical and phytopharmacological sciences has enabled elucidation of the composition and biological activities of several medicinal plant products including plant extract and essential oils. These products have been widely used around the world since ancient times for the treatment of various disorders such as diabetes, hypertension, peptic ulcer disease, microbial infection, sexual disorder and many more. Its popularity in the modern system of medicine is mainly due to their availability and fewer adverse reactions compared to synthetic drugs. Various scientifific investigations have been conducted to look for the potential of the extract from the plant or isolated compounds for the continued use of these products in the treatment and prevention of various kinds of human diseases. It is evident from the available literature and scientifific investigations that many plant species possess potential for use as a benefificial therapeutic remedy with multiple pharmacological actions such as analgesic, anti-inflflammatory, antipyretic, hypoglycemic, hypotensive, antimicrobial, antiulcer and anticonvulsant activities. The present review aims to provide relevant updated information about certain plant products, its composition, preparation and its fungicidal or fungistatic effects on different species of fungus as evaluated by studies done in the past. It introduces six medicinal plants that have been studied for their antifungal property and are found to be effective. The overall objective is to provide comprehensive information about the use of plant extract and essential oil for treating fungal infections and to explore the evidence supporting its effectiveness in treating fungal diseases without causing any serious adverse reactions.

Tuberculosis (TB) is a communicable disease caused by Mycobacterium tuberculosis (M. tuberculosis). WHO estimated that 10.4 million new (incident) TB cases worldwide in year 2016. The increased prevalence of drug resistant strains and side effects associated with the current anti-tubercular drugs make the treatment options more complicated. Hence, there are necessities to identify new drug candidates to fight against various sub-populations of M. tuberculosis with less or no toxicity/side effects and shorter treatment duration. Bacteriocins produced by lactic acid bacteria (LAB) attract attention of researchers because of its 'Generally recognized as safe' status. LAB and its bacteriocins possess an effective antimicrobial activity against various bacteria and fungi. Interestingly bacteriocins such as nisin and lacticin 3147 have shown antimycobacterial activity in vitro. As probiotics, LAB plays a vital role in promoting various health benefits including ability to modulate immune response against various infectious diseases. LAB and its metabolic products activate immune system and thereby limiting the M. tuberculosis pathogenesis. The protein and peptide engineering techniques paved the ways to obtain hybrid bacteriocin derivatives from the known peptide sequence of existing bacteriocin. In this review, we focus on the antimycobacterial property and immunomodulatory role of LAB and its metabolic products. Techniques for large scale synthesis of potential bacteriocin with multifunctional activity and enhanced stability are also discussed.
