Rubbing This Fish On Your Body Can Heal Open Wounds 300% Faster
That’s right we are talking Tilapia having super crazy healing properties but what is it specifically we are talking about that can heal wounds so fast? Collagen extracted from Tilapia can be applied as a wound dressing that helps accelerate healing. See image below for comparison.
Collagen from cows and pigs has been used previously, but the chance of disease transmission, in addition to religious objections, has prompted scientists to seek alternatives. The abundant supply of aquacultured tilapia (PDF) makes for an attractive substitute.
The researchers first analyzed the characteristics of collagen extracted from tilapia skin. Importantly, tilapia collagen did not appear to provoke an immune response. Furthermore, tilapia collagen encouraged the growth of fibroblasts and increased the expression of genes involved in wound healing. Thus, these experiments indicated that tilapia collagen is well-suited for regenerative medicine.
Finally, the authors made 1.8-cm-wide wounds on the backs of rats. The wounds were then treated with nothing (control), an algae-based wound dressing (Kaltostat), or tilapia (collagen). (See figure above.)
As shown, the tilapia collagen was most effective at healing the wound.
The authors perhaps will seek to commercialize this research. If they do, however, they will face a tough marketplace. For instance, the company Eqalix, which uses a soybean protein to promote wound healing, has a head start of a few years. Currently, Eqalix is seeking FDA clearance for its product.
