But there seems to be much more to Tannic acid than I ever realized. There is an enzyme called hyaluronidase (a collagenase or collagen digesting enzyme) which the cancer uses to digest or drill through the adjacent healthy cell host wall (which all contain hyaluronic acid derivatives) which allows it to spread. This is why hyaluronidase is actually described as a spreading factor for cancer. This enzyme therefore helps to spread the cancer horizontally or laterally into healthy host cells. What Tannic acid does is completely inhibit this hyaluronidase enzyme, thus halting any further cancer spread. From a research paper I found:
"We presented evidence that a hyaluronidase molecule is present on some but not all long term human tumor cell lines including colon adenocarcinoma. Hyaluronidase mRNA is also present in biopsies from patients with colon carcinomas but not from mRNA isolated from the normal colon tissue of the same patient. Expression of hyaluronidase on tumor cells could enable them to avoid intercellular adhesion, depolymerize the extracellular matrix, release growth factors stored in the matrix, and also induce angiogenesis, thereby facilitating the spread of tumor cells. From this link "Expression of hyaluronidase by tumor cells induces angiogenesis in vivo"
The above extract also showed induced angiogenesis (cancer's ability to form its own blood network system on and within the tumour) was greatly aided by hyalurodinase. To sum up the above research in simple layman's terms means that using Tannic Acid:
* De-cloaks the cancer as the enemy, fully allowing white blood cells to do their job.
* Stops angiogenesis and the spreading factor.
* Stops the cancer cells sticking or adhering to healthy host cells, thus disabling healthy cell penetration and invasion by the cancer cell.
* Preventing growth factors from being released in the healthy cells.
* The cumulative effect of tannic acid also helps to therefore stop or prevent cancer metastasis.

Here is also further evidence of how combining Vitamin C, Lysine, proline and Epigallotannins (very similar to tannic acid) in a combined protocol, has been proven to be very effective against cancers and particularly metastasis. See Dr Mathias Rath's Natural Cancer Formula Research.
