Issued in 1986 by the República Dominicana, this 50 centavos stamp belongs to the “Plantas Medicinales” (Medicinal Plants) series released for the 2° Seminario Farmacopea Popular Caribeña. It features the Guanábana (Annona muricata L.), known in English as soursop, a tropical fruit valued for its cooling and medicinal properties, especially used as a remedy for colds (resfriado). The stamp’s clean botanical illustration highlights the leaves and fruit, reflecting the country’s focus on traditional Caribbean herbal medicine and natural healing heritage.
