Convolvulus are a large group of plants that have been shown to have medicinal properties. In particular, Convolvulus plants may have mood elevating properties. It is not clear how these plants are able to elevate mood, but evidence suggests that this may be due to the presence of alkaloids and flavonoids within the plant tissues. In the case of flavonoids, studies have consistently shown that they are able to elevate depressed mood and relieve anxiety. Convolvulus plants have been shown to contain a range of flavonoids including quercetin, kaempferol, isorhamnetin, myricetin, rhamnetin, rutin, apigenin, chrysin, luteolin, vitexin, genistein, hesperidin and naringenin. The exact flavonoid content of the plants depends on the species and variety, and differences in flavonoid content between the flowers, stems, leaves and roots have been observed. The mood elevating effects of Convolvulus plants may therefore stem in part from the high concentrations of antioxidant flavonoids in the plant tissues.
