Career In March 1971, Han Taiyun of the 1st Affiliated Hospital started to treat cancer patients with a formula he collected from traditional Chinese medicine doctors. It was presumably an oral formula, and contained a mixture of many ingredients, including arsenic chemicals, mercury chloride, and cinobufagin venom toad. Later, Han Taiyun turned the formula into an intramuscular injection called "713" or "cancer spirit". For certain tumors, it worked and became a local hit. But Han Taiyun gave it up because the formula was too toxic for some patients, with side effects including renal toxicity and hypertension.
