Rating (out of 5): 2

Placental protein, particularly in the form of placental extracts, has been used traditionally in some countries such as India and China for wound healing and to support the treatment of external bleeding. The historical use is grounded in the belief that placental tissues possess regenerative, anti-inflammatory, and hemostatic properties, owing to their rich content of growth factors, cytokines, and proteins. In various traditional medical systems, preparations derived from human or animal placenta have been topically applied to wounds to promote healing and control bleeding.

However, scientific evidence specifically supporting the effectiveness of placental protein for external bleeding is limited. Some preclinical and small clinical studies have assessed placental extracts for wound healing and tissue regeneration, occasionally noting improved epithelialization and reduced healing time. The hemostatic (bleeding control) effect, however, is not well-substantiated in robust, high-quality clinical trials, and most of the available literature focuses on wound healing rather than acute bleeding control.

In conclusion, while the use of placental protein for external bleeding is primarily supported by traditional practices, there is a paucity of rigorous scientific data to confirm its efficacy for this specific indication. Its use persists in some regions more due to historical precedent than strong, evidence-based medicine.
