There is no basis for the claim that cancer cannot activate blood. After a lot of clinical observation, TCM oncologists found that cancer patients often have characteristics of blood stasis, including painful lumps, lightness and heaviness at night, sallow face, wrong skin nail, blue and purple tongue, or petechiae and petechiae, thin and astringent pulse, etc. In clinical practice, patients with these characteristics often have obvious effects after treatment with blood activation and dispersion methods. In clinical practice, for patients with these characteristics, treatment with blood activation and blood dispersion methods will often have obvious effects, with the disappearance of blue and purple tongue, petechiae, and astringent pulse, as well as the reduction of pain, and the maintenance of stable tumors for a long time, with some of them shrinking significantly. The clinical application of anti-tumor Chinese patent medicines also contains blood-activating ingredients, such as Addy injection and compound zebrano capsule, which are mainly composed of zebrano, and eleuthero injection, which is extracted from the Chinese medicine Curcuma longa, all have strong blood-activating effects. Moreover, so far, there is no clinical observation to confirm that blood activating drugs will promote the development of tumor, so cancer patients can use blood activating drugs as long as they have the manifestation of blood stasis.
