 Episode notes 
Apple-Like But Not An Apple
- Manzanilla de la muerte looks like a small apple but is taxonomically a Euphorbiaceae mangrove species with apples-like fruit.
- Its coastal, tropical distribution runs from southern Florida through the Caribbean and into northern South America.
White Latex Is The Real Weapon
- The plant produces a white, caustic latex throughout leaves, bark, fruit and wood that acts as a broad-spectrum chemical defense.
- That latex contains phorbol esters and a cocktail of resins, tannins and saponins that irritate or poison many animals and humans.
Avoid Rainfalls And Ingestion
- Avoid standing or sheltering under the tree during rain because water dissolves toxins and drips can cause blistering contact dermatitis.
- Do not ingest any part of the fruit or sap; ingestion causes severe throat pain, vomiting and diarrhea and may be life-threatening.
