Medicinal and aromatic plants and their secondary metabolites are also observed to be affected by climate change  . Phenological changes like early flowering and reduced vegetative phase are negatively affecting the productivity of such plants . While increasing atmospheric temperature and CO2 are reported to improve the biomass of Gynostemma pentaphyllum  , they adversely affect its antioxidant compounds/activity, health-promoting properties and phytochemical content . Experimental trials have shown that when medicinal plants are stressed by drought, phytochemical content increases, either by a decrease in biomass or by an increase in the actual production of metabolites  . The strong effects of climatic and non-climatic
