A Chinese medicine practitioner who allegedly claimed he could cure haemorrhoids with a unique course of treatment is facing a $1.4 million negligence claim from a patient. Medicine applied by Tai Kut-sing to patient Choi Chun-kwan, who is also known as Choi Hok-lun, was a cocktail of poison which caused excessive skin decomposition and loss, the Court of First Instance heard yesterday. Professor Zhang Li-hin of the Guangzhou Chinese Medicine University told the court the cocktail contained arsenic as well as herbal medicines. He said there had been five reported deaths on the mainland after its use by different practitioners to treat haemorrhoids. Mr Choi, 51, a taxi driver, suffered permanent injury as a result of the treatment. Barrister Selwyn So, for Mr Choi, said Mr Tai, who charged Mr Choi $8,000, had failed to exercise reasonable care and skill. Mr Tai failed to appear in court yesterday. Mr Choi testified he had suffered from haemorrhoids since 1994 and sought treatment from the defendant in his Aberdeen clinic on June 22, 1994. The pain suffered by Mr Choi after the treatment was so great he collapsed in the street and had to rest again in a restaurant, the court heard. Mr Choi said it took him six hours to get home. He was admitted to the Princess Margaret Hospital that night because of profuse bleeding, the court heard. Mr Choi said he was examined in September 1994 by a Canossa Hospital doctor and needed an operation. The claim against Mr Tai includes damages for Mr Choi's loss of earnings, pain and suffering and medical expenses. The case continues before Deputy Judge Esther Toh Lye-ping in the Court of First Instance.
