Description
Technical field
The present invention relates to Chinese medicine compositions, and in particular to a kind of Chinese medicine composition for treating malignant tumour further relates to its system
Preparation Method and application.
Background technique
Malignant tumour is to seriously endanger the formidable enemy of human health, oneself warp becomes the first killer of urban and rural residents, China death,
It and is in rise year by year trend.Anti- curing oncoma is the key subjects of contemporary medical science circle, extensively the concern by domestic and international medical field.So
And the treatment of malignant tumour is very difficult.Surgical operation, radiotherapy, the chemotherapy of doctor trained in Western medicine are currently treat malignant tumour three big basic
Means.However surgical operation not only brings huge physiology and psychological pain to patient, and its late result is also not to the utmost
People's will.The non-specific effect for killing tumour cell of radiation and chemotherapy causes normal cell and organ injury not can avoid, with
Cancer itself is not died of as some patients, but indirectly dies of toxicity brought by radiation and chemotherapy drug.By
It is not difficult to find out that, all there are some drawbacks in the big conventional therapy of the three of malignant tumour above, and people expect there is some new methods and hand
Duan Laiyu cancer is struggled.1994, Canadian schipper professor proposed in the new model about malignant tumour concept,
