[Effect of Echinacea purpurea tincture and its polysaccharide complex on the efficacy of cytostatic therapy of transferred tumors].

ABSTRACT

Experiments on C57LB/6 mice with transplanted Luis lung carcinoma showed that the officinal Echinacea purpurea preparation did not influence the efficacy of cytostatic therapy. This echinacea preparation did not change the development of metastases and even stimulated the tumor growth. In contrast, a hydrophilic polysaccharide complex isolated from echinacea increased the antitumor and antimetastatic activity of cyclophosphamide.
