Letter: Periwinkle cure

From Mr Ernest Kinson

Sir: Further to your article "Try a little flower power" (23 May), Roy Campbell, in his book on Portugal, describes how he was cured of diabetes when he visited his Portuguese friends in the Alentejo. He was given a concoction derived from periwinkle.

In the late Eighties, I related Mr Campbell's experience to an old friend who lived in Algarve and who, for many years, had suffered from diabetes.

Within six months of the treatment, my friend was leading a normal lifestyle.

Yours truly,

ERNEST KINSON
