Dragon's Blood (Croton lechleri / Sangre de Drago): Taspine Alkaloid, Proanthocyanidin Matrix, and Cutaneous Barrier Repair

The Liquid Red Latex of the Amazonian Canopy

When the bark of the slender Croton lechleri Tree is scored in the lowland rainforests of Peru, Ecuador, and Brazil, it exudes a thick, blood-red viscous sap known throughout Latin America as Sangre de Drago (Dragon\'s Blood).

1. Taspine Alkaloid: The Cell-Migration Accelerator

• Taspine: A unique alkaloid that stimulates the rapid chemotactic migration of fibroblast cells directly into epithelial defects, accelerating epidermal regeneration.
• Oligomeric Proanthocyanidins ($OPCs$ - 90% dry weight): Form a natural, sterile, breathable polymer film over skin abrasions, cross-linking collagen fibers and locking in hydration.

2. Traditional Internal and Topical Applications

• Topical: Rubbed directly onto small skin abrasions, insect bites, or minor burns where it dries into a protective seal.
• Internal: Historically diluted dropwise in water by indigenous tribes to soothe sensitive gastric mucosal linings.
