Escoazul
The escoazul or escozul (from escorpión azul - in Spanish: blue scorpion - the name by which it's known in Cuba) refers to different mix used in Cuban traditional medicine as an anti-inflammatory, whose composition may vary, but always containing a diluted dose of Rhopalurus junceus's poison, a species of scorpion found in Cuba, Haiti and Dominican Republic.
The Rhopalurus junceuss poison, coloured blue, contains a toxin whose composition and structure is still unknown.
The escozul gained fame when in Latin America and Europe was spread, through internet, the voice of a possible antineoplastic effect. After that, the Cuban Government started some studies, all in preliminary stages, in order to discover its real effects.
