GLOBAL MARKET DEMAND

In the global market, Vernonia is primarily known for its use as an ingredient in herbal supplements and traditional medicines. Some species of Vernonia are believed to have anti-inflammatory, antioxidant, and other health-promoting properties, which has led to an increase in demand for Vernonia-based products. Vernonia has also gained attention for its potential use as a source of biodiesel. The oil extracted from Vernonia seeds has a high content of vernolic acid, which has similar properties to those of castor oil. Vernonia oil has been shown to be a promising source of biodiesel due to its high oil content and low viscosity. Additionally, some species of Vernonia are used as ornamental plants in landscaping and gardening, and this has contributed to a small but growing demand for Vernonia plants in the horticulture industry. Overall, while Vernonia is not a major player in the global market, its diverse uses and potential as a source of health-promoting compounds and biodiesel make it an interesting plant genus to watch.
