A new glance at the role of traditional medicines in treatment of cancers.

In this letter, the authors noticed the previously published article entitled "How to transfer traditional knowledge about medicinal herbs? or TCM plants: a black box for modern oncologists" by Büntzel et al. The article mentioned traditional Persian Medicine (PM) as the second most published item in the field of medicine for the treatment of oral mucositis and polyneuropathy in cancer patients. We performed a second attempt to find more clinical trials on herbal medications using Iranian Medicine (IM), Traditional Iranian Medicine (TIM), or Iranian Traditional Medicine (ITM) as added terms to the keywords. In conclusion, we found four more clinical trials on herbal medicines in this field. This survey increases the number of PM trials detected by Büntzel, J et al. to 19 investigations.
