PINK PERIWINKLE

PINK PERIWINKLE

PINK PERIWINKLE is considered a weed by Australian authorities and eradication guidelines are readily available.  In reality, it’s just as much a new migrant as the invasive “white man” and holds high medicinal value.  The juice of fresh leaves displays antidiabetic activity by reducing blood glucose [1], the flower extract has wound-healing activity [2] & it’s vinca alkaloids (obtained via acid-base extraction) are used in cancer treatment [3] .  For these reasons, it is considered a high value plant within the pharmaceutical industry.  Next time you walk past it in your garden, give it a ‘wink’ or better yet – “thank you”.  And remember where it’s growing in case you need to use it’s medicinal gifts….not just another pretty flower at all!
