Obscure properties of a traditional herb Pittosporum neelgherrense used to treat snakebite envenoming against Daboia russelli venoms

In tropical nations, snakebite envenomation is a significant public health issue with negative human and social effects. This is due to three factors: 1) more species of the most hazardous snakes are present; 2) emergency medical assistance is not readily available; and 3) inadequate health care. The problems caused by snakebite envenomation have been partially resolved by immunotherapy. An extensive collection of medicinal herbs is recognized to have antivenomous properties in traditional medicine. However, very few species have undergone scientific investigation, and even fewer have had their active components separated and structurally and functionally defined. In this work, the anti-venom potential of hot and cold aqueous extracts from Pittosporum neelgherrense is evaluated using an in-vitro model. The experimental results showed that 4H-pyran-4-one, 2,3-dihydro-3,5-dihydroxy-6-methyl-(11.20), 1-Undecanol (16.38), Lauryl acetate (18.25), and Cyclotridecane (19.14) were phytochemical substances whose chemical structures were recognized by GCMS. The Direct and Indirect hemorrhagic activity was found to be completely neutralized by P. neelgherrense extract (44.61% hot plant extract & 55.38% cold plant extract) and the zone (2.4 mm), respectively. The neutralization of venoms was indicated by the zone (0.5–0.9 cm) of hydrolysis production of proteolytic activity. Additionally, the results of the gelatine liquefaction study demonstrated that clot formation was not triggered by venom at low concentrations (50:50) but was instead brought on by higher concentrations. The present study suggested that the neutralization of venom by hot water extracts of P. neelgherrense is a potentially therapeutic application.
