2.3 herb-drug interaction assessment
For checking herb-drug interactions, we used a drug interaction checker supported by natural medicine collaboration (URL: https://naturalmedicines.therapeuticresearch.com/). The scientific names of herbal medicines and the generic name of chemotherapeutic agents as pair of herb-drug check together. In this part, the scientific name of herbal medicines was determined and approved by two herbalists. According to the results, interactions were stratified in three levels: minor, moderate and major based on the evidence (anecdotal evidence, theoretically based on pharmacology, vitro studies, randomized and non-randomized clinical trials).
