I heard that stewed duck with konjac can cure cancer. My uncle got rectal cancer in 2004, and he has been eating konjac every day since the operation. He has lived for ten years since the operation. Uncle Er also got pancreatic cancer the year before last. He was treated with Chinese medicine in Chongqing Hospital of Traditional Chinese Medicine without surgery, chemotherapy and radiotherapy, and then he ate Chinese medicine and stewed duck with taro every day. After half a year of treatment, all indicators were normal, and I don't know if it was the cancer cells killed by taro. However, because Tianmao taro is highly toxic, it can only be removed by special treatment, so if we analyze it from the logic of fighting poison with poison, it should be effective. In Zizhong County, Sichuan Province, it is an open secret that Tianmao taro can prevent and treat cancer, so many people there have planted several Tianmao taro at home.
