Question

studies and researches about anti-fungal property of guyabano

Answer 1

Researchers verified Guyabano leaf's hypotensive properties in rats again in 1991. Several studies over the years have demonstrated that leaf, bark, root, stem, and seed extracts of Guyabano are antibacterial in vitro against numerous pathogens, and that the bark has antifungal properties. Guyabano seeds demonstrated active antiparasitic properties in a 1991 study, and a leaf extract showed to be active against malaria in two other studies (in 1990 and 1993). The leaves, root, and seeds of Guyabano demonstrated insecticidal properties, with the seeds demonstrating strong insecticidal activity in an early 1940 study. In a 1997 clinical study, novel alkaloids found in Guyabano fruit exhibited antidepressive effects in animals. According to naturopath Leslie Taylor, author of the 2005 book "The Healing Power of Rainforest Herbs,"& guyabano possesses antibacterial, antifungal and antiviral properties. Purdue University has conducted significant research on acetogenins funded by the National Institute of Health (NIH) and The National Cancer Institute. These studies have resulted in at least nine patents on the results around the antitumorous and insecticidal, antifungal uses of Guyabano.
