Periwinkle Twinkle

21 Jan

Catharanthus (Madagascar Periwinkle) is a genus of eight species of herbaceous perennial plants, seven endemic to the island of Madagascar, the eighth native to the Indian subcontinent in southern Asia. One species, C. roseus, has been widely cultivated and introduced, becoming an invasive species in some areas. C. roseus has gained interest from the pharmaceutical industry; the alkaloids vincristine and vinblastine from its sap have been shown to be an effective treatment for leukaemia. Although the sap is poisonous if ingested, some 70 useful alkaloids have been identified from it. In Madagascar, extracts have been used for hundreds of years in herbal medicine for the treatment of diabetes, as hemostatics and tranquilizers, to lower blood pressure, and as disinfectants. The extracts are not without their side effects, however, which include hair loss.

I create my own banners and I’ve fooled around with digital art for many years, using flowers from my garden. Here’s another pretty specimen to brighten a chilly winter day and remind us that spring is on it’s way.

Digg!
