- University of Seville Researchers from the Department of Pharmacology at the University of Seville have recently published a study in which they state that diets supplemented with aqueous extract of Annona muricata L. leaves can prevent the symptoms associated with fibromyalgia, so improving the lives of these patients. Leaves of the species Annona muricata L. come from a tree of between 4 and 6 metres in height, from the botanical family Annonacese. They are simple leaves, oblong and egg like or oblong and elliptical in shape and between 5 and 15 cm in length. This species is native to the tropical areas of the Americas and is especially abundant in the Amazon region. It is usually cultivated for its medicinal use. The leaves have different ethnomedical uses according to their country of origin. The most important uses in traditional medicine, scientifically validated in pre-clinical tests, are for inflammation, pain, infections, diabetes and cancer.

- Bruce Ames and his colleagues have pointed out that although detailed toxicological analysis has been conducted on synthetic chemicals, almost no information is available about the mutagenic or carcinogenic effects of the toxins produced by plants as a natural defense against fungi, insects, and animal predators. Tens of thousands of such compounds have been discovered, and he estimates that in the United States adults eat about 1.5 g of these compounds each daylevels that are approximately 10,000 times higher than those of the synthetic pesticides present in the diet. For example, cabbage contains 49 natural pesticides and metabolites, and only a few of these have been tested for their carcinogenic and mutagenic effects. a. With the introduction of new foods into the U.S. diet over the last 200 years (mangoes, kiwi fruit, tomatoes, and so forth), has there been enough time for humans to develop resistance to the mutagenic effects of the toxins present in those foods? b. The natural pesticides present in plants constitute more than 99% of the toxins we eat.
