This research was attempted to prove suppressing effect of medicinal plants on the intestinal absorption of toxic heavy metals. In vitro study was performed by membrane filtration considering intestinal absorption conditions. From drinking water contaminated singly with 10 and 50 times level of water quality standard for heavy metals, the removal ratio of lead was $40{\sim}60%$ by Chicorium intybus, Angelica acutiloba and Ganoderma lucidium. And the removal ratio of cadmium was $20{\sim}40%$. The removal ratio of lead contaminated with both was $30{\sim}50%$ by every sample similarly, the removal ratio of cadmium was $10{\sim}30%$. The removal ratio of Angelica acutiloba was more higher than Chicorium intybus and Ganoderma lucidium. Considering the extraction conditions of samples, $70^{\circ}C$, 2 min conditions were higher than $95^{\circ}C$, 10 min conditions, the removal ratios of heavy metals were similar. And the membrane filter permeated the material under 500 mw selectively, so the final filtrate could regard as passive transport in intestinal absorption. In conclusion, this research exhibited that the medicinal plants beverages have a suppressing effect on intestinal absorption of lead and cadmium in drinking water.
