The principle of low frequency electric impulsed production technique is that electric energy,stored in ca-pacitors through boosting,rectifying and charging circuits,are released instantaneously by trigger circuits to produce vibration waves which can improve seepage flow in forma-tions,thus enhancing recovery factor.

Objective: To explore the regulation of transdermal absorption of Secretio Bufonis (SB) and the effect of low frequency complex impulse current (LFCIC) on it.
