Researchers at Istituto di Scienze Neurologiche-CNR identified folk medical cures that were used by the Calabrian people for the treatment of malaria, as evidenced in writings produced between the 19th and 20th centuries.

The authors identify 53 plants used by Calabrian people to treat malaria, and note that some of these plants are still currently used in Calabrian folk medicine to treat various diseases.

From the Discussion:

“The methodology based on the analysis of historical sources regarding Calabrian folk medicine remedies for the prophylaxis and treatment of malaria, if not compared with similar studies, can be considered a case study where the ordinary methodologies of ethno-medical-biological research are combined with the methodologies pertaining to historical-anthropological sciences. In addition, this is part of a debate regarding the association between ethnobotany and ethnopharmacology and other disciplines, to improve our understanding of the human usage of plants.”

Noting that an understanding of how people of diverse cultural backgrounds have traditionally used plants and animals as medicinal substances during displacements is one of the most important objectives of ethnopharmacological studies, biologists at the Universidade Federal de São Paulo interviewed five migrants who described knowledge about 12 animals and 85 plants used medicinally in their places of origin. The five interviewees migrated from northeast and southeast Brazil and established themselves in Diadema in the 1940s.

From the Background:

“Cultural mixing mediated by the migration of people around the world has generated increasing interest in recent years within the field of ethnopharmacology. Medicinal plants have been used by human societies throughout history, also across geographical barriers. The continuous use of certain plants and animals for medicinal purposes over time reflects their potential therapeutic value. Such substances become even more promising when they are persistently used by migrating human groups despite the considerable distances travelled and the consequent exposure to different cultures and vegetal resources.”

Seven plants [Impatiens hawkeri W. Bull., [Artemisia camphorata Vill.], Equisetum arvensis L. [sic – Equisetum arvense?], Senna pendula (Humb. & Bonpl. ex Willd.) H.S. Irwin & Barneby, Zea mays L., Fevillea passiflora Vell. and Croton fuscescens Spreng)] and two animals (Atta sexdens and Periplaneta americana) showed maintenance of use among migrants during their displacement in Brazilian territory and have not yet been studied by pharmacologists.

The authors acknowledge that their work raises significant issues related to property rights, as the dynamic use of natural resources presents particularly varied influences: “The interviewed migrants had passed through several Brazilian cities and were exposed to distinct vegetation and cultures. In this migration, they have passed on and incorporated knowledge in an intensive exchange where formulas and uses are mixed and re-invented as a result of contact between cultures.”

Hot chilis to cool cancer

Oyagbemi AA, Saba AB, Azeez OI. Capsaicin: a novel chemopreventive molecule and its underlying molecular mechanisms of action. Indian J Cancer. 2010 Jan-Mar;47(1):53-8 [open access]

Researchers at the University of Ibadan undertook a review of the literature on the plant genus Capsicum (Solanaceae), a principal ingredient of hot red and chili peppers, as a cancer-suppressing agent.

From the conclusion:

“The use of phytochemicals present in fruits and vegetable has gained worldwide acceptance as a novel source of chemopreventive agents against cancer cells. These non-nutrient phytochemicals either block or reverse multistage carcinogenesis. Capsaicin, a pungent ingredient present in chili pepper has anti-inflammatory, antioxidant, antiproliferative and anti-cancer potentials. Capsaicin has chemopreventive effect against a wide of chronic inflammatory diseases, including cancer. Other potential benefits of capsaicin should be explored with the aim of brightening our understanding of the molecular mechanism associated with its anti-cancer activities.”

Chilis!
