"My 12 yr old male cat had lymphoma with a tumor the size of a ping pong ball on his neck. I gave him 2 eyedroppers of Essiac 3 times a day and I also added some tea to the Essiac formula that Echinacea, Chaparral Leaf and Red Clover. And I massaged the tumor with pure, cold pressed Castor Oil twice a day. In 4 weeks it was gone and he"s his old self. Please try it."
