Why Saying Cashew in Spanish Sparks Fierce Regional Debates Across Spain and the America's
In Mexican markets, asking for a cashew yields the phrase nuez de la India (literally, "nut of India"). This label emerged from Spanish colonial trade via the Manila Galleon and European maritime networks, where exotic spices and tropical nuts arriving from maritime routes through the East Indies earned broad, generalized geographical monikers. Today, major retail chains across Mexico package edible, salted cashews under this title without second thought.
However, this casual naming convention carries a genuine public health hazard. In alternative medicine circles across Latin America, the phrase nuez de la India also refers to the seed of Aleurites moluccanus (the candlenut tree) or Thevetia peruviana (yellow oleander). Shady online retailers and weight-loss supplement distributors market these dangerous seeds as miracle slimming aids. Unlike the harmless, nutritious cashew, these botanical imposters contain potent cardiac glycosides and toxalbumins that cause severe gastrointestinal distress, cardiac arrhythmias, and fatal poisonings.
Health agencies in Mexico (COFEPRIS), Spain (AEMPS), and the United States (FDA) have repeatedly issued warnings prohibiting toxic "slimming seeds" sold under the street name nuez de la India. For commercial buyers and travelers, context is vital: packaged edible snack nuts in Mexican supermarkets labeled nuez de la India are ordinary, heat-processed cashews. But unverified herbal remedies or raw medicinal nuts bearing that exact same label in traditional homeopathic stalls can be lethal.
