As a basic treatment of cancer

chemotherapy may induce adverse reactions

which is currently the core of the cancer researches. In traditional Chinese medicine（TCM）

chemotherapy induced adverse reactions is categorized into "deficiency detriment". Based on the theory of "treating detriment by supplementing"

the therapeutic methods of chemotherapy induced adverse reactions should be mainly supplementing and boosting. According to the occurrence timing of the commonly seen adverse reactions

such as gastrointestinal reaction

bone marrow suppression and external contraction

the additional use of TCM should be divided into different phases. In phase one（the first week of chemotherapy）

when gastrointestinal reactions occurs

Liujun Anwei Decoction（六君安胃汤） is recommended to fortify the spleen

harmonize the stomach

direct counterflow downward and arrest vomiting. In phase two（from the second week of chemotherapy）

when bone marrow suppression occurs

Qitu Erzhi Decoction（芪菟二至汤） is recommended to fortify the spleen

supplement the kidney

nourish blood and supplement essence. Additionally

when there is external contraction during chemotherapy due to insufficient healthy qi

Yinsang Decoction（银桑汤） can be used to clear heat and release the exterior. The sequential treatment regimen can precisely alleviate the adverse reactions caused by chemotherapy

while ensuring the effectiveness and safety.
