Results: The study had found that 57.66% of the patients used T&CM before diagnosis, while 33.66% begun using them after the diagnosis. Male patients have sought the doctor’s help more than female patients (p=0,022). As for socio-demographic findings, there was no significant statistical correlation between the use of T&CM and age, gender, occupation, educational background, monthly income, marital status, or family type. In terms of location, the patients residing in city centers utilized T&CM more than those living in smaller regions such as counties or villages (p=0,034). Among the post-diagnosis T&CM practices, phytotherapy was the most popularly applied (90.90%), followed by phlebotomy (5.45%), and leech therapy (3.63%). Amongst phytotherapy were the consumption of herbal teas (52%) and the use of Urtica urens (30%). Conclusion: It was observed that the knowledge level of the patients about T&CM was insufficient. It would be beneficial to carry out studies to increase the knowledge and awareness of patients about T&CM methods.
