Background: The Plant of Jatropha curcas is known for their many biological activities including antiviral, antifungal and antibacterial. Aim: To provide update knowledge on the phytochemistry, toxicology and antiviral activity of some medically interesting Jatropha curcas. Study Design: Multidisciplinary advanced bibliographic surveys and dissemination of the resulted knowledge. Results: The literature review shows that Jatropha curcas have antiviral properties on different types of viruses. Different parts of the plant such as leaves, roots, latex, seeds, fruits and other parts have been reported to have different compounds which have interesting bioactivities and antiviral properties. Conclusion: The present mini-review can therefore help inform future scientific research towards the development of anti-Hepatitis B virus and antiCovid-19 herbal drugs of relevance as well as nutraceuticals from J. curcas for the improvement of human health and wellbeing using reverse pharmacology approach. Molecular docking of some naturally occurring isolate compounds against anti-Hepatitis B virus protease is in progress.
