Dr. Cheng: In February of this year, you helped me to give my cat who is diagnosed with hyperthyroidism, a stab at a longer healthy life. You had sent me “Thyroidinum 200CH” to start with. Within a few days..she was another cat! My cat had an immediate turnaround with the treatment you advised. She responded so well. I still have some of the other medication left, but the Thyroidinum 200CH was what definitely got her on the right path. I would like to order another vial of this from you. I have nothing to lose at this point. She is eating a better diet (canned vs dry) and good quality and real chicken, but I really would like to try one more regime of this homeopathic pill. You are a very dedicated and helpful man, and I have recommended you to all who believe in this approach to treatment. I have no idea how long this will help her, but with my choice of diet for her and your advice, she is doing as well as I could have ever imagined. Thank you so much again.
