Entity of the month
Tradition has it that in 1638 when Lady Ana de Osorio, the Countess of Chinchón, the wife of the Viceroy of Peru, fell ill with malarial fever, she was treated with the bark of a tree (much later named the Cinchona tree in her honour by the Swedish botanist Carl Linnaeus). It was at the recommendation of the Spanish Jesuit missionaries who were taught the healing power of the bark by the native Incas. Her recovery was dramatic and when she returned to Spain, she brought with her large supplies of the powdered bark, originally known as 'Jesuit's Powder' [1,2].
