Influence of medicinal herbs decocted with different utensils on colony formation of gastric carcinoma cells.
In order to elucidate the different results obtained in cancer patients with similar condition and symptoms treated by the same medicinal herbs, an investigation of the utensils used for making decoctions was carried out. It was found that the decoction made by means of glassware, enamel and earthenware pots had the best effect of inhibiting the colony formation of human gastric carcinoma cells, the next were the decoctions made by means of unrefined iron pots, stainless steel pots and copper pots, and the worst was that made with aluminium pots. It was also found that there was no difference between the water contained in those utensils and normal saline in the influence on the colony formation of human gastric carcinoma cells. Therefore, it is believed that the difference in effect of the decoctions made by means of different kinds of utensils is not due to the trace dissolution of the utensil materials, but is most likely due to the occurrence of some chemical reactions while making the decoction. That the decoctions made by means of different utensils had different peak values in the absorption spectrum also supports this proposition.
