What is the key difference between Arista AH and PerClot starch?

Explanation:
The key difference is the form of starch each product uses. Arista AH is hydrolyzed starch, meaning the starch molecules have been partially broken down into smaller fragments. This makes it highly absorbent and enables faster absorption and gel formation in the wound, helping to stop bleeding and then resorb as healing progresses. PerClot uses crystalline (native) starch, with intact starch granules. It acts mainly as a physical barrier or scaffold to control bleeding and is absorbed more slowly than hydrolyzed starch. So, the best answer highlights that Arista AH is hydrolyzed starch while PerClot is crystalline starch.
